COLTO SERIES 8000: SUNDRIES

SECTION B8100: TESTING MATERIALS AND WORKMANSHIP

B8102 TESTING METHODS

Insert the following as a new first paragraph:

“Where reference is made to TMH test methods in this specification or the standard specifications, it shall be replaced with the relevant current published SANS test method.”

B8103 THE COSTS OF TESTING

(a) Process Control

Rename the heading as “Materials Quality Control” and replace the contents with the following:

“Testing shall be undertaken by a combined laboratory facility for process control (where the process control testing can be utilised as acceptance control), acceptance control and correlation testing subject to the following requirements laid down by the employer: (i) The contractor accepts the test results of the combined laboratory. Should there be any

doubts with regard to certain test results, this will be settled by an independent laboratory mutually agreed upon. The cost in such cases will be to the account of the party at fault.

(ii) The contractor accepts that the engineer will be in charge of the combined laboratory

exclusive of any prejudice towards the contractor in freely carrying out his process control obligations.

The total cost of the combined laboratory for the 42 month contract period has been estimated at R12 500 000 000. The estimated cost per month to establish and operate the combined laboratory for the contract period as listed above, allows for the following items:

Establishment of laboratory buildings Salaries and labour for all laboratory staff members Housing for all laboratory staff members Transport requirements (based on distance) for staff and material testing Provision of laboratory equipment (as required for the contract) A pay item for the monthly contribution from the contractor’s interim payment certificates has been provided under payment item B81.04.”

B8105 TESTING OF AGGREGATES

Add the following sub-clause:

“(g) Determination of Ethylene Glycol Durability Index

The Ethylene Glycol Durability Index shall be determined as follows:

(i) Apparatus

Suitable pans or basins Ethylene Glycol solution Stirring rod

(ii) Method

Obtain three or more representative samples from the source to be evaluated. If not already crushed, crush the material in order to obtain sufficient minus 19 mm plus 13 mm sized aggregate in order to totally cover the bottom of the basin or pan with a single layer of stone. Add

sufficient ethylene glycol to each basin ensuring that every aggregate particle is completely submerged. After soaking for 24 hours, gently stir the aggregate and allow to settle. Observe and record the response of the aggregate to the ethylene glycol according to the criteria listed in (iii) below. Continue the above cycle at intervals of 24 hours for a further 4 days, in each case recording the observed response. After 5 days allow the samples to remain submerged in the solution and observe and record the disintegration response after a total period of 15, 30 and 60 days have elapsed. (iii) Classification of response

After each cycle, classify and record the response of the aggregate as follows:

DISINTEGRATION CLASS

Class 1: No obvious effects, or only very minor spalling of sand sized particles or very small flakes. Class 2: Splitting of rock, accompanied by any other disintegrative effects. Class 3: Fracturing (spheroidal and/ or internal) without extensive spalling or distortion. Class 4: Fracturing (spheroidal and/or internal) with extensive spalling or distortion. Class 5: Complete disintegration. TIME CLASS

The time factor in the above disintegrative process is classified according to the time taken for the most serious effect of the expansive stresses to occur i.e. Class 4: 0 - 5 days Class 3: 6 - 15 days Class 2: 16 - 30 days Class 1: 31 - 60 days Class 0: Over 60 days (iv) Determination of Glycol Durability Index

The Ethylene Durability Index is determined by adding the class number as assigned for the specific disintegrative response observed to the class number as assigned for the period for this response to occur. A durability index ranging from 1 (no response) to 9 (rapid and complete disintegration) is thus determined.” Amend the heading of B8106 to read as follows:

“B8106 TESTING THE CONCRETE AND COVER TO STEEL REINFORCEMENT”

Add the following sub-clauses under B8106:

“(g) Trial panels for durability concrete (W class concrete)

As part of the durability class concrete mix design approval process, trial panels shall be constructed on the site (or at the laboratory) before construction of structural elements commences, to ensure that the contractor can successfully achieve the oxygen permeability, sorptivity and conductivity targets set for the in situ concrete with method of construction to be adopted. Each trial panel shall be constructed using the same type of concrete mix, shuttering type, placing and curing methods (including application rates of curing compounds if applicable) as to be used on the final structural element to be constructed. The dimensions of such a trial panel shall be 0.40 m wide, 0.60 m high and 150 mm thick. The panel shall be constructed vertically. It is suggested that 2 lifting hooks be cast into the panel to facilitate lifting, moving or disposal of panel. It most likely will be that one trial panel will be required for substructures (piers, abutments, retaining walls, etc) if the same grade concrete is specified for all substructures and another for the decks due to type of casting and curing methods. A third (or successively numbered) trial panel representative of the parapets, that utilize a different concrete mix, should also be prepared.

C3-213

The test area for taking of cores (taken in horizontal direction) shall not be less than 100 mm from all horizontal and vertical edges. The number of cores to be extracted and tested is described under B8106(i). (h) Test panels for durability concrete (W class concrete)

During casting of concrete on site, test panels shall be constructed on the site adjacent to where the concrete element is being placed. Each test panel shall be constructed with the same concrete, shutter type, compaction and curing methods being used in the element being cast (including same vibrator frequency and curing compound application rates), and be left to cure for 28 days adjacent to the concrete element. Thereafter it shall either be cored on site or transported to the laboratory for testing of the required durability parameters. The dimensions of the test panels shall be 0,4 m wide, 0,6 m high and 150 mm thick and be cast vertically to simulate vertical casts of the substructures and vertical faces of bridge decks. It is suggested that 2 lifting hooks be installed at both top ends of the test panel to assist with transport. For precast concrete, test panels will not be constructed, as cores will be drilled from the concrete elements at the precast yard before being placed at its final location. For the horizontal faces of in situ bridge decks and culverts, test panels will also not be constructed. Instead cores will be extracted from the top surface of the decks. The frequency of the testing and number of cores to be extracted is described under B8106(i). The test area for the taking of cores (taken in a horizontal direction) shall not be less than 100 mm all horizontal and vertical edges. The costs for construction of the test panels shall be deemed to be included under rates for payitem 64.01.” (i) Testing for concrete durability

Durability predictions for durability concrete prefixed ‘W’ will be based on the following tests that shall be carried out by an accredited laboratory approved by the engineer:

Oxygen permeability Water sorptivity Chloride conductivity (if specified)

Notes:

The test methods shall be as described below. For test no’s (i) and (ii) (and (iii) when required), cores of 70 ± 2 mm diameter shall be extracted from the test panels when the concrete reaches the age of at least 28 days but not more than 35 days and tested for the durability criteria set out in clause B6404(h) and used to determine the payment as per table B8212/1. Test No. (iii) may only be required where specified (e.g. within a XS-chloride environment along the coast or where chlorides are present in ground water). A sample for the purposes of durability testing is as defined in table B8106/1. The cores for durability testing shall be extracted from the test panels for process and acceptance control (at the frequency as shown in table B8106/2). Durability testing shall only be required for concrete specified as durability concrete with the prefix “W”. The number of samples to be taken shall be as shown in table B8106/2. Table B8106/1

Note:

1. Test panels required to be cast vertically. Additional cores required to be extracted from top of deck / major culvert slabs, i.e. in situ cores.

2. Note that where group of elements are cast on the same day, only one test panel will be required, but only if the same grade concrete is used.

3. Sample required to be taken from Precast element in casting yard. For edge beams, inner face to be cored.

For cores to be extracted from precast elements and top of bridge decks, the engineer will indicate the positions at which the cores will be extracted. Filling of the holes left by the drilling of the cores shall be the responsibility of the contractor and shall be carried out using an approved proprietary non-shrink repair mortar so as to restore structural integrity-, water retaining-, water excluding- and durability-properties of the structural element tested. It is recommended that the initial hole be suitably prepared to accept a cementitious non-shrink grout installed by (dry) ramming technique and a 25mm thick recess left at the final surface. The 25 mm thick recess can be finished with a colour-matched cementitious repair mortar and cured and rubbed down together with the remaining final surface to achieve the desired finish of the element as per Colto Clause 6207 (or as amended in the project specifications), particularly in terms of uniform colour, texture and appearance. If the test results indicate that the durability requirement has not been achieved, then the structural element shall be cored and tested for the durability criteria. The engineer will indicate the positions at which the cores will be extracted. The costs for testing of the structure shall be borne by the contractor. Filling of the holes left by the drilling of the cores shall be the responsibility of the contractor and shall be carried out with material as described in the paragraph above. Note that if testing has to be undertaken on sides of decks and walls, the cores shall be taken on the exposed faces of the concrete i.e. the sidewall face taking care not to cut the reinforcing bars. Where the cores do contain pieces of reinforcing steel, they shall not be used for the tests. The cores shall be extracted through the cover concrete from the test panels or constructed concrete element as applicable. The outer 5 mm of the exposed surface of the core shall be cut off and then a slice (30 ± 2 mm thick) shall then be cut and prepared for testing. The engineer will indicate the positions at which the cores will be extracted. The methodology and latest revisions for the durability index tests are available at the University of Cape Town’s web address at www.civil.uct.ac.za. In addition, the results of all the durability testing shall be submitted at least once a month in the required format to the University of Cape Town, where the present contact person is:

Assoc Prof. HD Beushausen - email: [email protected]. (j) Testing for cover to steel reinforcement

This procedure covers all measurements to be performed on reinforced concrete structures to establish conformance to specified cover requirements.

C3-215

(i) Apparatus (Cover meter devices)

Concrete cover testing shall be conducted using an approved electro-magnetic cover meter device complying with the relevant modern standards BS 1881 Part 204 (1988) and ACI 228.2R-13 and shall be capable of identifying the location and depth of reinforcement and to a lesser extent identify the diameter of embedded reinforcement. The daily use thereof may be delegated to the responsibilities of joint site laboratory. The contracts approach to sampling of particular areas and elements for cover testing shall be at the discretion of the engineer. All cover meter devices proposed for use shall possess documentary proof of calibration by the original equipment supplier, or equivalent calibration authority, certifying the electronic calibration of the cover meter device not exceeding 5 years since the latest (re)calibration. A standard control block (preferably with 40 mm cover) shall be used and maintained on site as a permanent control reference for cover depth. The cover meters shall be routinely checked on site using the control block under the control of the engineer and recorded daily in writing in the laboratory equipment calibration/control register. (ii) Test procedure and method

(1) Sampling ratio and bridge elements requiring particular cover measurement

The cover meter tests shall be conducted for a minimum 2% of surface area of concrete placed (1m2 for every 50m2 surface area). For bridges (or elements thereof) constructed utilising a half-width construction strategy, the sampling ratio shall be increased to 3,3% of surface area (1m

2 for every

30m2 surface area). This contract’s approach to sampling of particular areas and elements for cover

testing shall be selected at the discretion of the Engineer. Critical elements for cover surveys are parapets, deck edges including underside of cantilevers, deck soffits, lower portions of columns and abutments and walls. All parapets (F-shaped) including the parapet beam and aesthetic detail recesses shall be fully tested for cover compliance. In addition, the entire area up to 1,5 m high on piers, walls and abutments, including the rear of abutments and wingwalls, shall be fully tested before being backfilled. The engineer will identify other critical areas required to be surveyed. Should any of these areas shows deficiencies, the engineer may order additional cover tests on other areas at the contractors costs. (2) Preparation

The contractor shall complete in writing a cover survey request and record the request in writing in the established site test request system. The selected area for cover measurement is to be indicated on a sketch, appropriately referenced to clearly defined structural features to ensure that the area can be further investigated should a cover non-conformity be reported. The responsible person must identify the area to be scanned, take measurements on the required date and calculate the results in terms of the project specification. The cover meter device shall be checked against the standard control block immediately prior to each day of measurement. Any deviation of reading(s) on the standard control block shall be immediately reported to the engineer, who may instruct the immediate replacement of the cover meter device at the contractor’s expense. All measurements shall be performed in accordance with the cover meter equipment manufacturer’s guidelines. (3) Grid, block, or image scan method

Individual cover depth measurements are to be recorded in both primary orthogonal reinforcement directions of a marked grid as per the cover meter equipment manufacturer’s guidelines. A minimum of 24 individual cover depth measurements (CDM) shall be recorded from a grid area of at least 600mm by 600mm (0.36m2) and the individual arithmetic mean cover calculated for this specific grid area. An example of Image Scan information and presentation is shown in Figure B8106-3 below:

C3-216

Figure B8106-3 : Example of a Image scan output If the equipment used is not able to provide the above presentation it has to be done manually by determining the position of rebar, first and second reinforcement layers closest to surface, and manually record readings in order to establish the depth of rebar, as shown in Figure B8106-4 below.

Figure B8106-4 : Manual recording of readings” (4) Normalization procedure for the intended use of quick or linear scan methods

Where the contractor elects to utilize quick or linear scan methods, he is hereby duly alerted to the fact that only the outer rebar layer closest to the concrete surface is measured, resulting in the reporting of relatively smaller cover. The contractor shall ensure stricter control over the achievement of cover

Page 7: COLTO SERIES 8000: SUNDRIES SECTION B8100: TESTING MATERIALS … … ·  · 2015-08-17... and used to determine the payment as per table B8212/1. Test ... Additional cores required

C3-217

takes place on site to ensure full compliance where quick or linear scan methods are proposed and employed. The normalisation procedure shall be satisfactorily executed in full and submitted in writing to the engineer prior to the acceptance of the quick/linear scan method on site. The engineer shall duly consider the technical submission and elect to approve at his own discretion the test method provided that the straight line regression coefficient exceeds the minimum requirement specified below. The contractor shall perform a comparative parameter study comprising of a minimum range of 80 discrete individual cover surveys as recorded in the cover survey request system, where the quick/linear method is specifically limited to exactly the same grid area used for the grid scan. The comparative results shall be tabled for each grid area and specific structural element type, and the individual mean cover (mm) and standard deviation (mm) shall be reported for each cover method per grid area. A graphical XY plot of individual mean cover from the two cover methods, with the grid/block method plotted on the horizontal (independent variable) axis and the quick/linear method plotted on the vertical (dependant variable) axis. In order to accept the normalisation procedure, a squared linear regression coefficient (R

2) shall be equal to, or greater than 0.90. The comparative

analyses shall also determine the net reported shift in cover between the two methods, but the shift shall not under any circumstances be used to adjust any cover readings determined using the quick or linear method. (5) Quick or linear scan method

Individual CDM readings are to be taken perpendicular to the layer of rebar closest to the concrete surface for each scan area (>40 per m

2), so that an individual mean cover to reinforcement can be

determined for the tested area. Readings are to be taken to identify individual bars within each 1 m2. At least three cover readings, at 100 mm spacing, per an individual bar shall be shown in the test results but only the overall mean cover measurement would be used for payment purposes. Reports generated by the equipment shall be used for determining payment in accordance with table B8212/2a.

e.g. If specified cover is 50mm, the lower limit for full acceptance is:

50 mm x 85% = 42 mm (rounded down to the nearest integer). Where more than 5% of individual CDM readings are below specified lower limit (85%), the area shall be re-scanned, by Image, Block or Grid scan method, to verify the individual mean cover. An example of Quick Scan information and presentation is shown in Figure B8106-5 below. (iii) Processing, analysis and reporting of cover data

The overall mean cover per cover survey request shall be determined from a minimum of 3 individual mean covers calculated from 3 discrete scan areas totalling at least 1 m

2. The overall mean cover is

calculated as the arithmetic mean of at least 3 individual mean cover results (more individual mean cover results shall be determined for larger structural elements). The sample standard deviation (mm) shall be determined and reported for the same data set used to calculate the overall mean cover. Each individual bar reading, used to determine the minimum individual mean cover, shall exceed 60% of the specified cover. Where individual bar reading does not exceed 60% (refer table B8212/2), the contractor shall at his expense conduct a physical exploratory investigation to confirm the depth of reinforcement and to propose appropriate remedial measures subject to the agreement and written approval of the engineer. Cognizance to be taken of the effect to cover depth measured, where spliced bars are measured in same area as single bars. For splices, the size of rebar shall be corrected manually on the device by means of applying the following formula (approximately 1.41 x diameter of spliced rebar as shown in design). For the purposes of calculating the individual mean cover, individual CDM’s that have covers exceeding the specified nominal cover by the greater of twice (2,0x) the reinforcement diameter or

C3-218

25 mm, whichever is greater, shall be capped at specified cover plus the greater of twice (2,0x) the reinforcement diameter or 25 mm in the calculations.

Figure B8106-5 : Example of quick/linear scan output

Where insufficient cover are established before placing of concrete, e.g. Starter bars from base not correct position, remedial actions shall be performed before continuing with next concreting – these actions to be clearly recorded and area identified. The overall mean cover, categorised per element type and per specified cover range, shall be used to assess conformance with the requirements of table B8212/2. A Microsoft Excel (or similar) spreadsheet shall be used to consolidate and record all cover data. One worksheet shall record all unique cover survey request identifiers, the element type, the cover survey date, the specified nominal cover, the unique reference to the electronic file containing individual readings, the cover meter device used, the bar diameter setting used to record the individual cover readings, the arithmetic mean of individual readings (in mm, rounded off to nearest integer) i.e. Individual mean cover, the standard deviation (in mm) of the sample used to calculate the individual mean cover, the minimum individual reading, the maximum individual reading and information relating to any non-conforming work. A second worksheet shall record the element type, the specified nominal cover, and sufficient information to link the data to particular individual mean covers. The overall mean cover per element

Page 9: COLTO SERIES 8000: SUNDRIES SECTION B8100: TESTING MATERIALS … … ·  · 2015-08-17... and used to determine the payment as per table B8212/1. Test ... Additional cores required

C3-219

type per portion of work, standard deviation (mm) of the sample comprising the individual mean covers, the minimum individual mean cover used and the maximum individual mean cover used to calculate the overall mean cover. Global analysis of the cover results shall be reported for the contract comprising of: 1) the total number of individual CDM’s utilised to calculate the individual mean cover data per specified nominal cover , 2) the total number of individual mean covers reported per specified nominal cover, 3) the overall mean cover and standard deviation per structural element type (defined by the engineer) and per specified nominal cover, 4) determine the statistical degree of compliance based on single-sided Gaussian statistical tables (to three decimal places) and report the compliance percentage (%) to one decimal place. Pertaining to the overall mean cover; the arithmetic mean (mm), standard deviation (mm), maximum and minimum statistics shall be presented separately for the means and standard deviations of the global data package per specified nominal cover.

B8108 DETERMINING THE TOTAL APPROXIMATE DRY BULK RELATIVE DENSITY AND THE APPARENT DENSITY

Add the following at the end of this clause:

“For materials where the total water absorption, when determined according to TMH1 Methods B14 and B15, is in excess of 1,5%, the apparent density shall be calculated in accordance to the following formula:

This formula shall be used as an alternative to note (5) regarding soaking period, when so instructed by the engineer."

B8110 TESTS RELATING TO CHEMICAL STABILISATION

Add the following sub-clause:

“(d) The Wet-Dry Durability Test for cement and/or lime-treated materials using the hand-brush method (SANRAL METHOD)

(i) Scope

This method covers the procedure for determining the soil-cement losses obtained by repeated wetting, drying and hand brushing of hardened soil-cement specimens (see 5.4). (ii) Apparatus

(1) A moisture curing room capable of maintaining a relative humidity of 95 to 100 percent and a temperature of 22 to 25°C, or suitable plastic bags capable of holding specimens and carriers in an air tight condition in a water bath as described in 2.2 below. (2) A suitable water bath with thermostatic control capable of maintaining a temperature of 22 to 25°C. (3) A balance to weigh up to 10kg, accurate to 0.5g. (4) A drying oven capable of maintaining temperatures of 71 ± 3°C and 110 ± 5°C. (5) A wire scratch brush made of 50 mm by 1.6 mm flat 26 gauge wire bristles assembled in 50 groups of 10 bristles and mounted to form five longitudinal rows and 10 transverse rows on a 200 by 65mm wooden block. (iii) Method

(1) Preparation of specimens

Prepare specimens in accordance with the procedure described in the Appendix to method A19 in the TMH 1 with the following exceptions:

(b -a)

(d - a) + { (w - 1.0)/100 x (b - a) } - (c - b)

C3-220

Use the material passing the 37.5 mm sieve and discard the material remaining on the sieve. Use the apparatus and compaction method as described in TMH 1 method A7 (100% Modified AASHTO at predetermined OMC). (2) Curing of specimens

Rapid cure the specimens (see 5.6). Alternatively, and where instructed by the engineer, the specimens may be cured for seven days at a relative humidity of 95% to 100% and a temperature of 22°C to 25°C in a suitable curing room or in plastic bags and a suitable water bath. (3) Wetting, drying and brushing

After curing, remove the specimens from the curing room or plastic bags, allow to cool and submerge them in water at room temperature for a period of five hours. Remove the specimens from the water and place them in an oven at 71°C for 42 hours. Remove the specimens from the oven. Give each specimen two firm strokes over the full surface area with the wire scratch brush. The brush must be held parallel to the long axis of the specimen or parallel to the ends as required to cover all areas of the specimen. Apply these strokes to the full height and width of each specimen with a firm stroke corresponding to approximately 13.5 kN force (see note 5.5). (4) Determination of soil-cement losses

After 12 cycles, dry the specimens to constant mass at 100°C and determine the oven dry mass of the specimens. The data collected will permit the calculation of the soil-cement losses of the specimens after the prescribed 12-cycle test. (iv) Calculations

(1) Calculate the soil-cement loss of the specimens as a percentage of the original oven-dry mass of the specimens as follows:

L = W - N x 100 W

Where L = soil-cement loss (%) W = original calculated oven-dry mass (g) (calculated according to paragraph 3.5 in the

Appendix to method A19 in the TMH 1). N = final oven-dry mass (g).

(2) The percentage loss shall be calculated and reported to the nearest 0.1 percent. The results are normally required for stabilisation design purposes and should be reported graphically against relevant cement contents. (v) Notes

(1) Mass determinations of the specimens before and after brushing are usually made at the end of each cycle during research or special investigations. (2) Care is required when assessing results obtained on very coarse graded materials as "plucking" out of the aggregate pieces during the brushing process could result in very high losses of material, which may however not be truly indicative of its potential erosion resistance. (3) If it not possible to run the cycle continuously because of Sundays or holidays, or for any other reason, the specimens should be held in the oven during the layover period.

C3-221

(4) The test was originally developed to determine wet-dry durability of cement-treated material. It can, however, be used with equal success on material tested with other chemical stabilizers, for example lime, or mixes of lime and milled blast furnace slag, or cement and milled blast furnace slag. (5) The pressure of the brushing stroke is determined as follows:

Clamp a specimen in a vertical position on the edge of a platform scale and zero the scale. Apply vertical brushing strokes to the specimen and note the force necessary to register approximately 1.36 kg. (6) Rapid curing:

Seal each specimen airtight in a suitable container or plastic bag. Carefully place the briquettes on suitable holders or in pans and place in the oven at the relevant temperature and period given below:

Stabilizing agent Temp (°C) Time (Hours) Cement 70 – 75 24 ±0.5 PBFC 70 - 75 24 ±0.5 Lime 60 ±2 45 ±1 Lime / FA 60 ±2 45 ±1 Lime / MBFS 60 ±2 45 ±1

C1001 SCOPE

The Employer recognises environmental management as a key component of road infrastructure development and as part of its environmental policy has developed this Environmental Management Plan (EMPl) as a tool for continual improvement in environmental performance. This EMPl prescribes the methods by which proper environmental controls are to be implemented by the contractor. The duration over which the contractor’s controls shall be in place cover the construction period of the project as well as the limited time after contract completion defined by the Conditions of Contract for Construction for Building and Engineering Works Designed by the Employer (1999 edition) published by the Federation Internationale des Ingenieurs-Conseils (FIDIC) as the Defects Notification Period (maintenance period). The provisions of this EMPl are binding on the contractor during the life of the contract. They are to be read in conjunction with all the documents that comprise the suite of documents for this contract, particularly the conditions of any environmental authorisation and associated Environmental Management Programme (EMPr). In the event that any conflict occurs between the terms of the EMPl and the rest of the project specifications or environmental authorisation, the terms herein shall be subordinate. The EMPl is a dynamic document subject to similar influences and changes as are brought by variations to the provisions of the project specification. Any changes to the EMPl and/or environmental authorisation cannot occur without being submitted to the Employer who will manage the process of seeking approval of the change from the relevant authority. The EMPl identifies the following:

Relevant parties and their responsibilities; Construction activities that will impact on the environment; Specifications with which the contractor shall comply in order to protect the environment from

the identified impacts; and Actions that shall be taken in the event of non-compliance.

C1002 DEFINITIONS

Alien Vegetation: undesirable plant growth which includes, but is not limited to all declared category 1 and 2 listed invader species as set out in the Conservation of Agricultural Resources Act (CARA), 1983 regulations. Other vegetation deemed to be alien are those plant species that show the potential to occupy in number, any area within the defined construction area and which are declared to be undesirable. Construction Activity: any action taken by the contractor, his sub-contractors, suppliers or personnel during the construction process as defined in the contract documents. Environment: the surroundings within which the contract exists and comprises land, water, atmosphere, micro-organisms, plant and animal life (including humans) in any part or combination thereof as well as any physical, chemical, aesthetic or cultural inter-relationship among and between them.. Environmental Aspect: any component of a contractor’s construction activity that is likely to interact with the environment. Environmental authorisation: a written statement from the National Department of Environmental Affairs, (DEA), with the general and specific conditions and the EMPr recording its approval of an application for a planned undertaking that triggers listed activities in the Environmental Impact Assessment (EIA) regulations of the National Environmental Management Act (NEMA).

C3-230

Environmental Impact: any change to the environment, whether desirable or undesirable, that will result from the effect of a construction activity. An impact may be the direct or indirect consequence of a construction activity. Environmental Impact Assessment (EIA): a systematic process of identifying, assessing and reporting environmental impacts associated with an activity and includes basic assessment and scoping and environmental impact reporting. Environmental Management Programme (EMPr): the embodiment of this EMPl to ensure that undue or reasonably avoidable adverse impacts of a development are prevented, and to ensure that positive impacts are enhanced. It thus addresses the how, when, who, where and what of integrating environmental mitigation and monitoring measures through identified projects. Road Reserve: a corridor of land, defined by co-ordinates and/or proclamation, within which the road, including access intersections or interchanges, is situated. A road reserve may, or may not, be bounded by a fence. Site; the site is defined in the FIDIC conditions of contract and in the scope of works. It is bound by the limits of construction as shown in the drawings or the title of the project and extends to also include the following:

Areas outside the construction zones where accommodation of traffic is placed; All borrowpits defined in the applications approved by the relevant Department of Mineral

Resources (DMR); All haul roads constructed by the contractor for purposes of access; Any non-adjacent sites specified in the contract documentation; The contractor’s and his subcontractors’ camp sites; and

for the purposes of this EMPl includes areas outside of, but adjacent to, the road reserve that may be affected by construction activities. Spoil material: is material unsuitable for construction of the road pavement and for which no other useful purpose can be found in appurtenant works on the project (e.g. for the provision of protection beams). Such material is considered as waste material that requires spoiling at convenient areas to be identified by the engineer and/or contractor within the Site. Spoil material does not require removal to a designated landfill site unless it contains identifiable hazardous contaminants.

C1003 LEGAL REQUIREMENTS

C1004 ADMINISTRATION OF ENVIRONMENTAL OBLIGATIONS

Copies of this EMPl shall be kept at the site office and must be distributed to all senior contract personnel who shall familiarise themselves with its contents. Implementation of this EMPl requires the involvement of several stakeholders, each fulfilling a different but vital role as outlined herein, to ensure sound environmental management during the construction phase of a project. (a) The Employer

The Employer is the holder of authorisations issued by the relevant environmental regulating authorities responsible for authorising and enforcing environmental compliance. The Employer and anyone acting on the Employer’s behalf is accountable for the potential impacts of the activities that are undertaken and is responsible for managing these impacts. (b) The Engineer

The engineer has been appointed by, and acts for, the Employer as its on-site implementing agent and carries the responsibility to ensure that the contractor undertakes its construction activities in such a way that the Employer’s environmental responsibilities are not compromised. The engineer will, within seven days of receiving a contractor’s request for approval of a nominated Designated Environmental Officer (DEO), approve, reject or call for more information on the nomination. The engineer will be responsible for issuing instructions to the DEO where environmental considerations call for action to be taken. If in the opinion of the engineer the DEO is not fulfilling his/her duties in terms of this EMPl, the engineer may, after discussion and agreement with the Employer, exercise his powers under FIDIC condition of contract clause 6.9 and instruct replacement of the DEO in writing and with stated reasons. (c) The Contractor

The contractor is responsible for project delivery in accordance with the prescribed specifications, among which this EMPl shall be included. The contractor shall receive and implement any instruction issued by the engineer relating to compliance with the EMPl including the removal of personnel or equipment. Compliance with the provisions contained herein or any condition imposed by the environmental approvals shall become the responsibility of the contractor through an approved Designated Environmental Officer (DEO). The contractor shall nominate a person from among his site personnel to fulfil this function and submit to the engineer for his approval the curriculum vitae of the proposed DEO. This request for approval shall be given, in writing, at least fourteen days before the commencement of any construction activity clearly setting out reasons for the nomination, and with sufficient detail to enable the engineer to make a decision. (d) The Designated/Dedicated Environmental Officer (DEO)

Once a nominated representative of the contractor has been approved he/she shall become the DEO and shall be the responsible person for ensuring that the provisions of this EMPl are complied with during the life of the contract. The DEO shall submit regular written reports to the engineer, but not less frequently than once a month.

Page 23: COLTO SERIES 8000: SUNDRIES SECTION B8100: TESTING MATERIALS … … ·  · 2015-08-17... and used to determine the payment as per table B8212/1. Test ... Additional cores required

C3-233

The DEO may undertake other construction duties unless the Appendix to Tender prescribes this position as ‘dedicated’ as opposed to the standard position being ‘designated’. However, the DEO’s environmental duties shall hold primacy over other contractual duties and the engineer has the authority to instruct the contractor to reduce the DEO’s other duties or to replace the DEO if, in the engineer’s opinion, he/she is not fulfilling his/her duties in terms of the requirements of this EMPl. Such instruction will be in writing clearly setting out the reasons why a replacement is required. As a minimum the DEO shall have an accredited diploma qualification in environmental or natural sciences or equivalent. Alternatively, the DEO shall have a minimum of 2 years’ experience in a similar role in construction or other environmental regulatory field. In addition to the compliance duties relating to EMPl the DEO shall also provide full cooperation whenever the contractor is subjected to regular environmental audits. The DEO shall be a dedicated officer with no other encumbrances. (e) Environmental Control Officer (ECO)

The Environmental Control Officer (ECO) is an independent environmental specialist appointed by the engineer to objectively and regularly monitor the contractor’s implementation of this EMPl and the EMPr as may be determined by the sensitivity of the project or by conditions of authorisations. These are ‘internal’ audits and the regularity determined by the environmental approvals, usually once a month. Other ad hoc or ‘external’ audits ordered by the Employer may be conducted by other environmental specialists.

C1005 TRAINING

(a) Qualifications

The (DEO) shall have the minimum qualifications as prescribed above, and must be conversant with all legislation pertaining to the environment applicable to the contract. He/she must be appropriately trained in environmental management and possess the skills necessary to impart environmental management skills to all personnel involved in the contract. The contractor shall ensure that adequate environmental training takes place. All employees shall have been given an induction presentation on environmental awareness. Where possible, the presentation needs to be conducted in the language of the employees. (b) Content

Apart from induction environmental training should, as a minimum, include the course content below and no induction or course should be given until the engineer has been afforded the opportunity to appraise it and provide comment. (i) The importance of conformance with all environmental policies and the consequences of departure from standard operating procedures; (ii) Environmental impacts, actual or potential, caused by work activities, prevention measures to avoid them and mitigation measures when they occur; (iii) Work force roles and responsibilities in achieving conformance with the environmental policy and procedures and with the requirement of the Employer’s environmental management systems, including emergency preparedness and response requirements; and (iv) The environmental benefits of improved personal performance. (c) Induction

In the case of permanent staff the contractor shall provide evidence that such induction courses have been presented. In the case of new staff (including contract labour) the contractor shall inform the engineer when and how he intends concluding his environmental training obligations.

The role of the DEO cannot be underestimated and once approved he/she shall be on the site at all times, and before the contractor begins each construction activity he/she shall give to the engineer a written statement setting out the following: (i) The type of construction activity about to be started. (ii) Locality where the activity will take place. (iii) Identification of the environmental aspects and impacts that might result from the activity. (iv) The methodology of impact prevention for each activity or aspect. (v) The methodology of impact containment for each activity or aspect. (vi) Identification of the emergency/disaster potential for each activity (if any) and the reaction procedures necessary to mitigate impact severity. (vii) Treatment and continued maintenance of impacted environment. The contractor shall programme his work in such a way that each cause and effect of a construction activity is also identified and the activity planned so as to prevent any impact from happening and shall demonstrate that he is capable of carrying out any repair and reinstatement of the damaged environment. These requirements shall be concurrent with the time constraints to produce method statements for each construction activity in compliance with the provisions of the project specifications. The contractor shall provide such information in advance of any or all construction activities provided that new submissions shall be given to the engineer whenever there is a change or variation to the original. The engineer may provide comment on the methodology and procedures proposed by the DEO, but he shall not be responsible for the contractor’s chosen measures of impact mitigation and emergency/disaster management systems. However, the contractor shall demonstrate at inception and at least once during the contract that the approved measures and procedures function properly.

(b) Spillages

Streams, rivers and dams shall be protected from direct or indirect spillage of pollutants such as refuse, garbage, cement, concrete, sewage, chemicals, fuels, oils, aggregate, tailings, wash water, organic materials and bituminous products. In the event of a spillage, the contractor shall be liable to arrange for professional service providers to clear the affected area. Responsibility for spill containment and treatment (whether hazardous or not) lies with the contractor. The individual causing a spill, or who discovers a spill, must report the incident to his/her DEO or to the engineer. The DEO will assess the situation in consultation with the engineer and act as required. In all cases, the immediate response shall be to contain the spill. The exact treatment of polluted soil / water shall be determined by the contractor in consultation with the DEO and the engineer. Areas cleared of hazardous waste shall be re-vegetated according to the engineer’s instructions. Should water downstream of the spill be polluted, and fauna and flora show signs of deterioration or death, specialist hydrological or ecological advice will be sought for appropriate treatment and remedial procedures to be followed. The requirement for such input shall be agreed with the engineer. The costs of containment and rehabilitation shall be for the contractor’s account, including the costs of specialist input as well as the sampling and testing of the water quality upstream and downstream of the spill. Water quality sampling and testing, and further treatment shall continue until upstream and downstream results correspond with each other. (c) Water use and control

The contractor’s use of water shall take into consideration that it is a scarce commodity, and shall be optimised. Where applicable, authorisation shall be obtained from the Department of Water Affairs (DWA) before water is drawn from streams or new boreholes developed. The contractor shall also ensure that any stream deviations or diversions are undertaken in such a manner that the impact on the environment is minimised. Method statements shall be submitted to the engineer for comment, detailing how the work will be undertaken, what risks are foreseen and what measures will be employed to minimise such risks. Notwithstanding any comments by the engineer, no work on stream deviations or diversions can commence without written approval from DWA. The quality, quantity and flow direction of any surface water runoff shall be established prior to disturbing any area for construction purposes. Cognisance shall be taken of these aspects and incorporated into the planning of all construction activities. Before a site is developed or expanded, it shall be established how this development or expansion will affect the drainage pattern. Recognised water users / receivers shall not be adversely affected by the expansion or re-development. No water source shall be polluted in any way due to proposed changes. Streams, rivers, pans, wetlands, dams, and their catchments shall be protected from erosion and from direct or indirect spillage of pollutants such as refuse, garbage, cement, concrete, sewage, chemicals, fuels, oils, aggregate, tailings, wash water, organic materials and bituminous products. The contractor shall submit to the engineer his proposals for prevention, containment and rehabilitation measures against environmental damage of the identified water and drainage systems that occur on the site. Consideration shall be given to the placement of sedimentation ponds or barriers where the soils are of a dispersive nature or where toxic fluids are used in the construction process. The sedimentation ponds must be large enough to contain runoff so that they function properly under heavy rain conditions up to a 1:5 year severity. The contractor shall submit to the engineer the results of monthly testing of water samples taken above and below the site of new culvert or bridge construction. No taking-over can be authorised until the water quality is shown to be at pre-construction levels or better. (d) Vegetation management

The contractor shall be responsible for the management of vegetation by protection of indigenous vegetation, especially identified protected species, and the prevention of alien vegetation germinating in areas disturbed by road construction activities within and outside the road reserve. This includes, for

Page 26: COLTO SERIES 8000: SUNDRIES SECTION B8100: TESTING MATERIALS … … ·  · 2015-08-17... and used to determine the payment as per table B8212/1. Test ... Additional cores required

C3-236

example, service roads, stockpile areas, stop/go facilities, windrows and wherever material generated for or from road construction has been stored temporarily. This responsibility shall continue for the duration of the defects notification period. CARA-listed category 1 and 2 alien species will be removed and replaced with the planting of specified indigenous species. (e) Dust control

Dust caused by construction activities shall be controlled by means such as water spray vehicles and applied at sufficient frequency so as not to cause nuisance to adjacent habitation or affect farming activities or natural vegetation. Vegetation cover should also be kept for as long as possible to reduce the area of exposed surfaces. Dust emissions from batching and screening plants shall be subject to the relevant legislation and shall be the subject of inspection by the relevant authorities. (f) Noise control

The contractor shall endeavour to keep noise generating activities to a minimum. Noises that could cause a major disturbance, for instance blasting and crushing activities, should only be carried out during the hours prescribed by the conditions of contract (i.e. normal hours). Should such noise generating activities have to occur at any time outside normal hours the people in the vicinity of the noise-generating activity shall be warned about the noise well in advance and the activities kept to a minimum. Relevant legislation shall also be taken into consideration, and any practical mitigation measures adopted. No noise generating activity outside of normal hours, regardless of its proximity to residences, can take place without application to the engineer for approval. The application shall be accompanied by the noise containment measures proposed. (g) Energy consumption

The contractor shall take into consideration the impacts of high energy consumption, both from a cost and emissions point of view. Energy use shall be minimised, and where possible, alternative energy sources such as solar utilised. Furthermore, the contractor shall undertake a study of the consumption of carbon units his chosen method of construction produces in the execution of his programme. In conjunction with the engineer who will provide complete cooperation in this study, a month by month output shall be compiled and efforts made to see how these outputs can be curtailed and reduced.

C1007 ENVIRONMENTAL MANAGEMENT OF CONSTRUCTION ACTIVITIES

The contractor shall undertake “good housekeeping” practices during construction as stated in the COLTO Standard Specifications for Roads and Bridges and the FIDIC conditions of contract. This will help avoid disputes on responsibility and allow for the smooth running of the contract as a whole. Good housekeeping extends beyond the wise practice of construction methods that leaves production in a safe state from the ravages of weather to include the care for and preservation of the environment within which the site is situated. The construction activities addressed below shall become part of the contractor’s obligations regarding his programme of work and incorporated into the required method statements for workmanship and quality control. (a) Site establishment

(i) Site Plan

The site refers to an area with defined limits on which the project is located. The contractor shall establish his construction camps, offices, workshops, staff accommodation and testing facilities on the site in a manner that does not adversely affect the environment. However, before any site establishment can begin, the contractor shall submit to the ECO for his comments and to the engineer for his approval, plans of the exact location, extent and construction details of these facilities and the impact mitigation measures the contractor proposes to put in place. The plans shall detail the locality as well as the layout of the waste management facilities for litter, kitchen refuse, sewage and workshop-derived effluents. The site offices should not be sited in close

Page 27: COLTO SERIES 8000: SUNDRIES SECTION B8100: TESTING MATERIALS … … ·  · 2015-08-17... and used to determine the payment as per table B8212/1. Test ... Additional cores required

C3-237

proximity to steep areas, as this will increase soil erosion. Preferred locations would be flat areas along the route. If the route traverses water courses, streams and rivers, it is recommended that the offices, and in particular the ablution facilities, aggregate stockpiles, spoil areas and hazardous material stockpiles are located as far away as possible from any water course. No camp establishment, including satellite camps, can be placed within 32 metres of an identified wetland unless the contractor has applied to DWA and DEA and received authorisation to do so. Regardless of the chosen site, the contractor’s intended mitigation measures shall be indicated on the plan. The site plan shall have been submitted and approved before establishment commences. Detailed, electronic colour photographs shall be taken of the proposed site before any clearing may commence. These records are to be kept by the ECO and the engineer for consultation during rehabilitation of the site in order that rehabilitation is, as a minimum, done to a standard similar to pre-construction activities. (ii) Vegetation

The contractor has a responsibility to inform his staff of the need to be vigilant against any practice that will have a harmful effect on vegetation. The natural vegetation encountered on the site is to be conserved and left as intact as possible. Vegetation planted at the site shall be indigenous and in accordance with instructions issued by the engineer. Only trees and shrubs directly affected by the works, and such others as may be indicated by the engineer in writing, may be felled or cleared. In wooded areas where natural vegetation has been cleared out of necessity, the same species of indigenous trees as were occurring shall be re-established. Protected trees may not be removed without a permit from the Department of Agriculture, Forestry and Fisheries. Contravention of a notice of listed protected tree species under the National Forests Act, 1998 is regarded as a first category offence that may result in a fine or imprisonment for a period up to three years, or to both a fine and imprisonment. Rehabilitation shall be undertaken using only indigenous tree, shrub and grass species. Special attention shall be given to any search and rescue operation identified during the environmental application process, removal to an on-site nursery for continuous nurturing and protection and later replanting. The contractor should be alert to this procedure and apply to the engineer to approve it even though no allowance has been made in the contract documents. Any proclaimed weed or alien species that propagates during the contract period shall be cleared by hand before seeding. Fires shall only be allowed in facilities or equipment specially constructed for this purpose. The need for a firebreak shall be determined in consultation with the engineer and the relevant authorities, and if required a firebreak shall be cleared and maintained around the perimeter of the camp and office sites. The contractor’s staff shall at no time make fires for purposes of keeping out the cold unless they are contained in purpose-built containers capable of preventing runaway fires if knocked over and the ashes collected and safely and environmentally disposed of on a daily basis. (iii) Water management

Water for human consumption shall be available at the site offices and at other convenient locations on site. All effluent water from the camp/office sites shall be disposed of in a properly designed and constructed system, situated so as not to adversely affect water sources (streams, rivers, pans, dams etc). Only domestic type wastewater shall be allowed to enter this system. (iv) Heating and cooking fuel

The contractor shall provide adequate facilities for his staff so that they are not encouraged to supplement their comforts on site by accessing what can be taken from the natural surroundings. The contractor shall ensure that energy sources are available at all times for construction and supervision personnel for heating and cooking purposes.

C3-238

(b) Sewage management

Particular reference in the site establishment plan shall be given to the treatment of sewage generated at the site offices, site laboratory and staff accommodation and at all localities on the site where there will be a concentration of labour. Sanitary arrangements should be to the satisfaction of the engineer, the local authorities and legal requirements. Safe and effective sewage treatment will require one of the following sewage handling methods: septic tanks and soak-aways, dry-composting toilets such as “enviro loos”, or the use of chemical toilets which are supplied and maintained by a specialist service provider. The type of sewage management will depend on the geology of the area selected, the duration of the contract and proximity (availability) of providers of chemical toilets. Should a soak-away system be used, it shall not be closer than 800 metres from any natural water course or water retention system. The waste material generated from these facilities shall be serviced on a regular basis. The positioning of the chemical toilets shall be done in consultation with the engineer. Toilets and latrines shall be easily accessible and shall be positioned within walking distance from wherever employees are employed on the works. Use of the veld for this purpose shall not, under any circumstances, be allowed. Outside toilets shall be provided with locks and doors and shall be secured to prevent them from blowing over. The toilets shall also be placed outside areas susceptible to flooding. The contractor shall arrange for regular emptying of toilets and shall be entirely responsible for enforcing their use and for maintaining such latrines in a clean, orderly and sanitary condition to the satisfaction of the engineer. (c) Waste management

The contractor’s intended methods for waste management shall be outlined and implemented at the outset of the contract, and shall be to the satisfaction of the engineer. Opportunities for avoiding, reducing, reusing and recycling of materials should be identified upfront, as should constraints for their implementation. All personnel shall be instructed to dispose of all waste in the proper manner. (i) Solid waste

Solid waste shall be stored in an appointed area in covered, tip-proof metal drums or similar container for collection and disposal. Disposal of solid waste shall be at a licensed landfill site or at a site approved by the relevant authority in the event that an existing operating landfill site is not within reasonable distance from the project area. No waste shall be burned or buried at or near the project area. (ii) Litter

No littering by construction workers shall be allowed and any locality where motorists are encouraged or forced to stop shall be effectively controlled for litter collection. During the construction period, the various contractor’s facilities shall be maintained in a neat and tidy condition and the site shall be kept free of litter. Measures shall be taken to reduce the potential for litter and negligent behaviour with regard to the disposal of all refuse. At all places of work the contractor shall provide litter collection facilities for later safe disposal at approved sites. Particular emphasis on litter control measures shall apply at stop/go facilities. (iii) Hazardous waste

Hazardous waste such as oils shall be disposed of at an approved landfill site. Special care shall be taken to avoid spillage of bitumen products such as binders or pre-coating fluid to avoid water-soluble phenols from entering the ground or contaminating surface water. Under no circumstances shall the spoiling of bituminous products on the site, over embankments, in borrow pits or any burying, be allowed. Unused or rejected bituminous products shall be returned to the supplier’s production plant. Any spillage of bituminous products shall be attended to immediately and affected areas shall be promptly reinstated to the satisfaction of the engineer.

C3-239

(iv) Construction and demolition waste

The opportunity for recycling and reuse of construction and demolition waste as fill for road embankments, land reclamation and drainage control must first be explored and take priority before the option of declaring these materials a ‘waste’. The contractor is encouraged to actively engage with authorities and landowners adjacent to the site and identify where such ‘waste’ materials can be usefully deployed to repair existing environmentally damaged areas such as erosion dongas. (d) Control at the workshop

The contractor’s management and maintenance of his plant and machinery will be strictly monitored according to the criteria given below, regardless of whether it is serviced on the site (i.e. at the place of construction activity or at a formalised workshop). (i) Hazardous Material Storage

Petrochemicals, oils and identified hazardous substances shall only be stored under controlled conditions. All hazardous materials such as bitumen binders shall be stored in a secured, appointed area that is suitably fenced, bunded and has restricted entry. Storage of bituminous products shall only take place using suitable containers to the approval of the ECO and the engineer. The contractor shall provide proof to the engineer that relevant authorisation to store such substances has been obtained from the relevant authority. In addition, hazard signs indicating the nature of the stored materials shall be displayed on the storage facility or containment structure. Before containment or storage facilities can be erected the contractor shall furnish the engineer with details of the preventative measures he proposes to install in order to mitigate pollution of the surrounding environment from leaks or spillage. The preferred method shall be a concrete floor that is bunded. Any deviation from the method will require proof from the relevant authority that the alternative method proposed is acceptable to that authority. The proposals shall also indicate the emergency procedures in the event of misuse or spillage that will negatively affect an individual or the environment. (ii) Fuel and gas storage

The contractor shall take cognisance of the limits set by legislation for the storage of fuels and acquire the necessary authorisation for storage capacity beyond these. All fuel shall be stored in a secure area in steel tanks supplied and maintained by the fuel suppliers. An adequate bund wall, 110% of volume, shall be provided for fuel and diesel areas to accommodate any leakage spillage or overflow of these substances. The area inside the bund wall shall be lined with an impervious lining to prevent infiltration of the fuel into the soil. Any leakage, spillage or overflow of fuel shall be attended to without delay. Gas welding cylinders and LPG cylinders shall be stored chained in a secure, well-ventilated area exterior to any building wall. (iv) Oil and lubricant waste

Used oil, lubricants and cleaning materials from the maintenance of vehicles and machinery shall be collected in a holding tank and sent back to the supplier. Water and oil should be separated in an oil trap. Oils collected in this manner, shall be retained in a safe holding tank and removed from site by a specialist oil recycling company for disposal at approved waste disposal sites for toxic/hazardous materials. Oil collected by a mobile servicing unit shall be stored in the service unit’s sludge tank and discharged into the safe holding tank for collection by the specialist oil recycling company. All used filter materials shall be stored in a secure bin for disposal off site. Any contaminated soil shall be removed and replaced. Soils contaminated by oils and lubricants shall be collected and disposed of at a facility designated by the local authority to accept contaminated materials. (e) Clearing the site

In all areas where the contractor intends to, or is required to clear the natural vegetation and soil, either within the road reserve, or at designated or instructed areas outside the road reserve, a plan of

Page 30: COLTO SERIES 8000: SUNDRIES SECTION B8100: TESTING MATERIALS … … ·  · 2015-08-17... and used to determine the payment as per table B8212/1. Test ... Additional cores required

C3-240

action shall first be submitted to the engineer for his approval. Working areas shall be clearly defined and demarcated on site to minimise the construction footprint. ‘No-go- areas’ and other sensitive areas shall also be clearly demarcated on site, and staff must be made aware of them. The plan of action shall contain a photographic record and chainage/land reference of the areas to be disturbed. This shall be submitted to the engineer for his records before any disturbance/stockpiling may occur. The record shall be comprehensive and clear, allowing for easy identification during inspections. (f) Soil management

(i) Topsoil

Topsoil shall be removed from all areas where physical disturbance of the surface will occur and shall be stored and adequately protected. The contract will provide for the stripping and stockpiling of topsoil from the site for later re-use. Topsoil is considered to be the natural soil covering, including all the vegetation and organic matter. Depth may vary at each site. The areas to be cleared of topsoil shall include all storage areas. All topsoil stockpiles and windrows shall be maintained throughout the contract period in a weed-free condition. Weeds appearing on the stockpiled or windrowed topsoil shall be removed by hand. Soils contaminated by hazardous substances shall be disposed of at an approved waste disposal site. The topsoil stockpiles shall be stored, shaped and sited in such a way that they do not interfere with the flow of water to cause damming or erosion, or itself be eroded by the action of water. Stockpiles of topsoil if they are to be left for longer than 6 months, shall be analysed, and if necessary, upgraded before replacement. Stockpiles shall be protected against infestation by weeds. The contractor shall ensure that no topsoil is lost due to erosion – either by wind or water. Areas to be top-soiled and grassed shall be done so systematically to allow for quick cover and reduction in the chance of heavy topsoil losses due to unusual weather patterns. The contractor’s programme shall clearly show the proposed rate of progress of the application of topsoil and grassing. The contractor shall be held responsible for the replacement, at his own cost, for any unnecessary loss of topsoil due to his failure to work according to the progress plan approved by the engineer. The contractor’s responsibility shall also extend to the clearing of drainage or water systems within and beyond the boundaries of the road reserve that may have been affected by such negligence. (ii) Subsoil

The subsoil is the layer of soil immediately beneath the topsoil. It shall be removed, to a depth instructed by the engineer, and if not used for road building it shall be stored and maintained separately from the topsoil so that neither stockpile is contaminated by the other. This soil shall be used for rehabilitation purposes by first spreading it over the excavated slopes without interfering with or contaminating the stockpiled topsoil. Whilst in stockpile it shall be maintained free from erosion and weed infestation in the same way as for topsoil stockpile maintenance. (g) Earthworks and layerworks

This section includes all construction activities that involve the mining of all materials, and their subsequent placement, stockpile, spoil, treatment or batching, for use in the permanent works, or temporary works in the case of deviations. Before any stripping prior to the commencement of construction, the contractor shall have complied with the requirements of this EMPl. In addition, the contractor shall take cognisance of the requirements set out below. (i) Quarries and borrow pits

The contractor’s attention is drawn to the requirement of the Department of Mineral Resources, that before entry into any quarry or borrow pit, an EMPr for the establishment, operation and closure of the quarry or borrow pit shall have been approved by the Department. It is the responsibility of the contractor to ensure that he is in possession of the approved EMPr or a copy thereof, prior to entry into the quarry or borrow pit. The conditions imposed by the relevant EMPr are legally binding on the contractor and may be more extensive and explicit than the requirements of this specification. In the

Page 31: COLTO SERIES 8000: SUNDRIES SECTION B8100: TESTING MATERIALS … … ·  · 2015-08-17... and used to determine the payment as per table B8212/1. Test ... Additional cores required

C3-241

event of any conflict occurring between the requirements of the specific EMPr and these specifications the former shall apply. The cost of complying with the requirements shall be deemed to be included in existing rates in the Pricing Schedule. (ii) Excavation, hauling and placement

The contractor shall provide the ECO and the engineer with detailed plans of his intended construction processes prior to starting any cut or fill or layer. The plans shall detail the number of personnel and plant to be used and the measures by which the impacts of pollution (noise, dust, litter, fuel, oil and sewage), erosion, vegetation destruction and deformation of landscape will be prevented, contained and rehabilitated. Particular attention shall also be given to the impact that such activities will have on the adjacent built environment. The contractor shall demonstrate his “good housekeeping”, particularly with respect to closure at the end of every day so that the site is left in a safe condition from rainfall overnight or over periods when there is no construction activity. (iii) Spoil sites

The contractor shall be responsible for the safe siting, operation, maintenance and closure of any spoil site he uses during the contract period, including the defects notification period. This shall include existing spoil sites that are being re-entered. Before spoil sites may be used proposals for their locality, intended method of operation, maintenance and rehabilitation shall be given to the ECO for his comments and to the engineer for his approval. The location of these spoil sites shall have signed approval from the affected landowner before submission to the ECO and the engineer. No spoil site shall be located within 500m of a wetland and/or within 100m of any watercourse. A photographic record shall be kept of all spoil sites for monitoring purposes. This includes before the site is used and after re-vegetation. The use of approved spoil sites for the disposal of hazardous or toxic wastes shall be prohibited unless special measures are taken to prevent leaching of the toxins into the surrounding environment. Such special measures shall require the approval of the relevant provincial or national authority. The same shall apply for the disposal of solid waste generated from the various camp establishments. The engineer will assist the contractor in obtaining the necessary approval if requested by the contractor. Spoil sites will be shaped to fit the natural topography. Depending on availability these sites shall receive a minimum of 75mm topsoil and be grassed with the recommended seed mixture. Appropriate grassing measures to minimise soil erosion shall be undertaken by the contractor. This may include both strip and full sodding. The contractor may motivate to the engineer for other acceptable stabilising methods. The engineer may only approve a completed spoil site at the end of the defects notification period upon receipt from the contractor of a landowner’s clearance notice and an engineer’s certificate certifying slope stability. (iv) Stockpiles

The contractor shall plan his activities so that materials excavated from borrow pits and cuttings, in so far as possible, can be transported direct to and placed at the point where it is to be used. However, should temporary stockpiling become necessary, the areas for the stockpiling of excavated and imported material shall be indicated and demarcated on the site plan submitted in writing to the engineer for his approval, together with the contractor’s proposed measures for prevention of environmental damage, containment and subsequent rehabilitation. The areas chosen shall have no naturally occurring indigenous trees and shrubs present that may be damaged during operations. Care shall be taken to preserve all vegetation in the immediate area of these temporary stockpiles. During the life of the stockpiles the contractor shall at all times ensure that they are positioned and sloped to create the least visual impact, constructed and maintained so as to avoid erosion of the material and contamination of surrounding environment and kept free from all alien/undesirable vegetation. After the stockpiled material has been removed, the site shall be re-instated to its original condition. No foreign material generated / deposited during construction shall remain on site. Areas affected by stockpiling shall be landscaped, top soiled, grassed and maintained at the contractor’s cost until clearance from the engineer and the relevant national authority is received.

C3-242

Material milled from the existing road surface that is temporarily stockpiled in areas approved by the engineer within the road reserve, shall be subject to the same condition as other stockpiled materials. Excess materials from windrows, in situ milling or any detritus of material from road construction activities may not be swept off the road and left unless specifically instructed to do so in the contract documentation or under instruction from the engineer. In all cases, the ECO shall comment on and the engineer shall approve the areas for stockpiling and disposal of construction rubble before any operation commences and shall approve their closure only when they have been satisfactorily rehabilitated. (v) Blasting activities

Wherever blasting activity is required on the site (including quarries and/or borrow pits) the contractor shall rigorously adhere to the relevant statutes and regulations that control the use of explosives. In addition, the contractor shall, prior to any drilling of holes in preparation for blasting, supply the engineer with a risk assessment and locality plan of the blast site on which shall be shown the zones of influence of the ground and air shock-waves and expected limits of fly-rock. The plan shall show each dwelling, structure and service within the zones of influence and record the existing positions and conditions of the dwellings/structures/services including, lengths and widths of cracks, as well as the condition of doors, windows, roofing, wells, boreholes etc. The contractor, alone, shall be responsible for any costs that can be attributed to blasting activities, including the collection of fly-rock from adjacent lands and fields. The submission of such a plan shall not in any way absolve the contractor from his responsibilities in this regard. The contractor shall also indicate to the engineer the manner in which he intends to notify the adjacent communities and/or road users the times and delays to be expected for each individual blast. (h) On site plant

(i) Crusher, screening plants and concrete batching plants

Crushing plants and concrete batching plants, whether sited inside or outside of defined quarry or borrow pit areas, shall be subject to the requirements of the applicable industrial legislation that governs gas and dust emissions into the atmosphere. Such sites will be the subject of regular inspections by the relative authorities during the life of the project. In addition, the selection, entry onto, operation, maintenance, closure and rehabilitation of such sites shall be the same as for those under section C1007(g)(i) of this EMPl, with the exception that the contractor shall provide additional measures to prevent, contain and rehabilitate against environmental damage from toxic/hazardous substances. In this regard the contractor shall provide plans that take into account such additional measures as concrete floors, bunded storage facilities, linings to drainage channels and settlement dams. Ultimate approval of these measures shall be from the relevant national authority, as shall approval of closure. The engineer will assist the contractor in his submissions to the relevant authority. Screening activities shall be undertaken so that dust and noise is minimised. This can be done by carefully choosing the site for the activity, and by using slightly damp material. Effluent from concrete batch plants and crusher plants shall be reused where possible or treated in a suitable designated sedimentation dam to the legally required standards to prevent surface and groundwater pollution. The designs of such a facility should be submitted to the engineer for approval. The contractor shall invite the relevant department to inspect the site within 2 months after any plant is commissioned and at regular intervals thereafter, not exceeding 12 months apart. (ii) Asphalt Plant

Asphalt plants are considered to be one of the scheduled processes listed in the Environmental Impact Assessment Regulations of 2010. The activity triggered by the asphalt for road construction purposes is activity 26 of GN. R. 545, which states: “Commencing of an activity, which requires an atmospheric emission license in terms of Section 21 of the National Environmental Management: Air Quality Act, 2004 (Act No 39 of 2004) except where Activity 28 in Notice No R544 of 2010 applies.” Commencing with activity 26 of GN R. 545 requires Scoping and Environmental Impact Reporting (S&EIR) in order to obtain an environmental authorisation. In the event the use of an on-site asphalt

Page 33: COLTO SERIES 8000: SUNDRIES SECTION B8100: TESTING MATERIALS … … ·  · 2015-08-17... and used to determine the payment as per table B8212/1. Test ... Additional cores required

C3-243

plant is considered the contractor shall be responsible to obtain the necessary permit from the Department of Environmental Affairs, regardless of where the site is situated. Operation of the plant shall conform to the same requirements as for a crushing plant or concrete batching plant under C1007(h)(i) above.

C1008 AREAS OF SPECIFIC IMPORTANCE

Any area, as determined and identified within the project documents as sensitive or of special interest within the site shall be treated according to the express instructions contained in these specifications or the specific, approved EMPr. The contractor may offer alternative solutions to the engineer in writing should he consider that construction will be affected in any way by the hindrance of the designated sensitive area or feature. However, the overriding principle is that such defined areas requiring protection should not be changed. Every effort to identify such areas within the site will have been made prior to the project going out to tender. The discovery of other sites with archaeological or historical interest that have not been identified shall receive ad hoc treatment. (a) Archaeological sites

If an artefact on site is uncovered, work in the immediate vicinity shall be stopped immediately. The contractor shall take reasonable precautions to prevent any person from removing or damaging any such article and shall immediately upon discovery thereof inform the engineer of such discovery. The South African Heritage Resource Agency (SAHRA) is to be contacted, and a SAHRA-registered archaeological consultant may undertake the necessary work involved in confirming the find and advising on how it should be preserved or removed. Work may only resume once clearance is given in writing by the archaeologist. If a grave or midden is uncovered on site, or discovered before the commencement of work, then all work in the immediate vicinity of the graves/middens shall be stopped and the engineer informed of the discovery. The South African Heritage Resource Agency and the South African Police Services (SAPS) should be contacted and in the case of graves, arrangements made for an undertaker to carry out exhumation and reburial. The undertaker will, together with SAHRA, be responsible for attempts to contact family of the deceased and for the place where the exhumed remains can be re-interred.

C1009 REHABILITATION

The contractor shall be responsible for the re-establishment of grass within the road reserve boundaries for all areas disturbed during construction. This includes, for example, service roads, stockpile areas, stop/go facilities, windrows and wherever material generated for, or from, construction has to be stored temporarily, and designated or instructed areas outside the road reserve. It also includes the area where site offices were erected which may require rehabilitation at the end of the contract. All construction material, including concrete slabs and barbecue (braai) areas shall be removed from the site on completion of the contract unless written approval from the relevant landowner demonstrates it is to be left in place. Responsibility for re-establishment of vegetation shall extend until expiry of the defects notification period. However, the employer reserves the right to continue holding retention monies (or not releasing guarantees in lieu of retention) depending upon the state of cover at the end of the defects notification period. Such extension may continue until closure of the relevant quarry or borrow pit has been secured, Rehabilitation of affected areas should be undertaken as early as possible when the relevant activities are done in order to reduce further environmental damage. All re-vegetation should be undertaken using indigenous vegetation. The standard of rehabilitation should be to the satisfaction of the engineer and the relevant authorities. The Department of Minerals Resources will only issue closure certificates for borrow pits and quarries when they are satisfied with the rehabilitation undertaken. It should also be noted that in some cases there is a requirement for a final environmental audit covering the extent of the project.

C1010 RECORD KEEPING

The engineer and the DEO will continuously monitor the contractor’s adherence to the approved impact prevention procedures and the DEO shall submit regular written reports to the ECO and to the engineer, at least once a month. The engineer shall issue to the contractor a notice of non-compliance whenever transgressions are observed. The DEO shall document the nature and magnitude of the non-compliance in a designated register, the action taken to discontinue the non-compliance, the action taken to mitigate its effects and the results of the actions. The non-compliance shall be documented and reported to the engineer in the monthly report. Copies of any authorisations or EMPrs (including those for specific borrow pits or quarries used on the project) shall be kept on site and made available for inspection by visiting officials from the employer, relevant environmental departments or internal/external auditors.

C1011 COMPLIANCE AND PENALTIES

The contractor shall act immediately when a notice of non-compliance is received and correct whatever is the cause for the issuing of the notice. Complaints received regarding activities on the construction site pertaining to the environment shall be recorded in a dedicated register and the response noted with the date and action taken. This record shall be submitted with the monthly reports and an oral report given at the monthly site meetings. Any non-compliance with the agreed procedures of the EMPr and this EMPl is a transgression of the various statutes and laws that define the manner by which the environment is managed and, therefore, any avoidable non-compliance, dependant on severity, may be considered sufficient grounds for contact to be made with relevant provincial or national authorities to invite their sanction. The engineer’s decision with regard to what is considered a violation, its seriousness and the action to be taken against the contractor shall be final. Failure to redress the cause shall be reported to the relevant authority. The responsible provincial or national authority may ensure compliance and impose penalties relevant to the transgression as allowed within statutory powers.

C1012 PROJECT SPECIFIC CONDITIONS

1. Introduction 1.1 Brief project description The South African National Roads Agency SOC Limited (SANRAL) commissioned traffic studies of the N7 between the Melkbos Intersection and Malmesbury in 2008 and 2012 to assess the possible requirement for upgrading this section of the N7. The conclusion of both studies was that the road section needs to be upgraded from two lanes to four lanes by 2015. SANRAL has divided this section of the N7 into the following three project phases:

Phase 1: Melkbos Intersection (Section 1, km 17) to Atlantis South Intersection (Section 1, km 26);

Phase 2: Atlantis South Intersection (Section 1, km 26) to Kalbaskraal (Section 1, km 39); and Phase 3: Kalbaskraal (Section 1, km 39) to Hopefield Intersection (Section 2, km 6).

The proposed upgrade of Section 1 is necessary to increase the capacity and improve safety levels of this section of the N7. The specific rationale for all three phases of the N7 route upgrade is to:

Comply with freeway standards; Improve traffic safety; Increase the traffic capacity to accommodate current and future traffic volumes; and Improve free-flow traffic movement.

This Construction Environmental Management Programme (EMP) deals with Phase 2 of the proposed N7 upgrading, namely the proposed improvement of Section 1 between the Atlantis South Intersection at km 26 and Kalbaskraal at km 39, a distance of approximately 13 km. This would entail the following:

Upgrading the existing single carriageway to a dual carriageway with a median separating the carriageways;

Constructing a new grade-separated interchange with ramp terminals at an appropriate access point;

Closing off the existing accesses for public roads and private properties onto the N7 and rerouting them to adjacent and new roads in accordance with freeway standards; and

Constructing approximately 20 km of new access roads to link existing roads and private properties to the N7 via the new interchange.

1.2 Aims of the Construction EMP The purpose of the EMP is to ensure that impacts on the environment associated with the construction phase are prevented and, where they cannot be prevented, are kept to a minimum and rehabilitated. The Construction EMP sets environmental targets for the Contractor (defined as the lead Contractor and any nominated or selected Sub-contractors) and reasonable standards against which the Contractor’s performance can be measured during the construction phase. This document will form the basis for the environmental specifications that the Contractor, in terms of the construction contract, will be obliged to adhere to during construction. This document will be included in the contract documentation for the construction phase and will thus form a binding agreement between the Contractor and the Applicant, SANRAL. 1.3 CONTENTS OF THE construction EMP The Construction EMP comprises the following sections: Section 1: Introduction: This section includes the project information, aims of this Construction EMP and describes the content of this Construction EMP. Section 2: Administration and regulation of environmental obligations: This section identifies the management structure and responsibilities of the various stakeholders. The procedures for environmental management and monitoring of the construction phase are also presented.

Explanation of the importance of complying with the Construction EMP; Discussion of the potential environmental impacts of construction activities; Explanation of the management structure of individuals responsible for matters pertaining to the

Construction EMP; Employees’ roles and responsibilities, including emergency preparedness; Explanation of the mitigation measures that must be implemented when carrying out their

activities; Explanation of the specifics of the Construction EMP and its specification; and Explanation of the Environmental Do’s and Don’ts (see Annexure B). It is recommended that awareness posters be developed and placed on site in highly visible areas to provide the required information when it needs to be referred to as well as reminding employees of their obligations with regard to environmental protection. Throughout the presentations (posters, meetings, slideshows, etc.), it is recommended that visual aids be used to explain the potential risks and management thereof as thoroughly as possible. The awareness training for this project should aim to prevent, and where prevention is not possible, mitigate detrimental environmental impacts. In particular, it should promote awareness of environmental risks and management thereof. The Contractor shall keep records of all environmental training sessions, including names of attendees, dates of their attendance and the information presented to them. Records of environmental training sessions shall be submitted to the ECO. 2.7 Meetings The ECO shall meet with the RE and DEO on a monthly basis, or more frequently as required during the initial stages of the project. The ECO may attend monthly construction site meetings (Contractor/ Engineer/ RE/ DEO) when considered necessary. 2.8 Inspection procedures The day-to-day monitoring and verification that the Construction EMP is being adhered to shall be undertaken by the RE and the DEO. The ECO shall visit and inspect the site once a month to ensure that correct operational procedures are being implemented and that the Contractor is complying with the environmental specifications in the Construction EMP. Additional site inspections by the ECO may be needed during the initial and final stages of the project. The ECO shall address any queries to the RE. If the queries cannot be resolved at this level, they shall be referred to the Engineer and, if necessary, to DEA. 2.9 Record of activities The RE, ECO and DEO shall keep a record of activities on site, including but not limited to meetings attended, Method Statements received and approved, issues arising on site, cases of non-compliance with the Construction EMP, penalties / fines issued and corrective action taken to solve problems that arise.

2.10 Fines A system of fines shall be implemented to ensure compliance with the Construction EMP (see Annexure C). Where the Contractor inflicts non-repairable damage upon the environment or fails to comply with any of the environmental specifications of the Construction EMP this would constitute a breach of Contract for which the Contractor may be liable to pay a fine. The Contractor is deemed not to have complied with the Construction EMP if: There is evidence of contravention of the Construction EMP specifications, including any non-

compliance with an approved Method Statement; Construction activities take place outside the defined boundaries of the site; Environmental damage ensues due to negligence; The Contractor fails to comply with corrective or other instructions issued by the Engineer within a

specific time period; and/or The Contractor fails to respond adequately to complaints from the public. If excessive infringement with regard to any of the above (as determined by the Engineer) is registered, then SANRAL reserves the right to terminate the Contractor’s contract. The system of fines shall be implemented in the following way: Fines shall be issued per incident at the discretion of the Engineer; Fines shall be issued in addition to any remedial costs incurred as a result of non-compliance

with the environmental specifications; The Engineer shall inform the Contractor of the contravention and the amount of the fine, and

will deduct the amount from the Contractor’s monthly Payment Certificates; and Fines, including but not limited to those activities presented in Annexure C, shall be imposed by

the Engineer on the Contractor, his staff and/or the Sub-contractors’ staff for contravention of the environmental specifications. Where there are ranges, the amount shall depend on the severity and extent of the damage done to the environment.

Failure by any employee of the Contractor or their Sub-contractors to show adequate consideration to the environmental aspects of the contract shall be considered sufficient cause for the RE or ECO to recommend to the Engineer to have that employee removed from the site. The RE or ECO may, through the Engineer, also order the removal of equipment that is causing continual environmental damage. 2.11 Internal review and auditing The Contractor and DEO shall establish an internal review procedure to monitor the progress and implementation of the Construction EMP. Where necessary, and upon the recommendation of the RE and/or the ECO, procedures that require modification shall be changed to improve the efficiency of the Construction EMP. All significant modifications to the Construction EMP shall be approved by DEA before these changes or adjustments to the Construction EMP are implemented. Any changes or adjustments to the Construction EMP shall be registered in the daily records of the RE. Adjustment and update of the original Construction EMP document is not required when these ad hoc changes are made. At the conclusion of the project an environmental audit report shall be compiled and submitted to DEA within 30 days of the completion of the rehabilitation activities. This report shall be compiled by the ECO, in collaboration with the RE, DEO and the Contractor. It shall, as a minimum, outline the implementation of the Construction EMP, and highlight any problems and issues that arose during the construction period to report, on a formal basis, the lessons learned from this project. 2.12 Authorisations and permits Copies of all environmental related permits for construction activities associated with the proposed project must be submitted to DEA for record keeping.
