SECTION 01310

CONTRACTOR'S CONSTRUCTION SCHEDULE

PART 1 - GENERAL

1.01 SCOPE

This section specifies the procedures for preparing the construction schedule used for

planning and managing construction activities. The schedule provides a basis for

determining the progress status of the project relative to the completion time and specific

dates.

1.02 DESCRIPTION

The Contractor shall prepare a time scale network schedule using a critical path method. A

general guide for preparing such a schedule is contained in The Use of CPM in

Construction, a Manual for Contractors, published by the Associated General Contractors

of America.

The schedule shall depict all significant construction activities and all items of work listed

in the breakdown of contract prices submitted by the Contractor in accordance with the bid

schedule. The dependencies between activities shall be indicated so that it may be

established what effect the progress of any one activity has on the schedule.

Detailed network activities shall include, in addition to construction activities, the

submittal and approval of samples of material and shop drawings, the procurement of

critical materials and equipment, and their installation and testing. All submittals of

equipment and materials in Divisions 11, 13, 14, 15 and 16 shall be shown on the schedule

together with appropriate allowances for review and delivery times, installation, testing and

training as appropriate. All activities of the City and Construction Manager that affect the

progress of the work shall be shown. Any omission of work from the schedule required for

contract compliance shall not excuse the Contractor from completing such work within any

applicable completion date.

Completion time shall be shown on the schedule. Activities making up the critical path

shall be identified.

No activity on the schedule shall have a duration longer than 21 calendar days except

activities comprising only fabrication and delivery, which may extend for more than 21

calendar days. Activities which exceed these limits shall be divided into more detailed

components. The scheduled duration of each activity shall be based on the work being

performed during the normal 40-hour work week with allowances made for legal holidays

and normal weather conditions.

The Contractor shall not work on legal holidays except by permission of the Construction

11

Manager. Legal holidays are defined as the holidays observed by the respective job

classifications as defined by the California Department of Industrial Relations, Prevailing

Wage Determinations. The Contractor shall notify the Construction Manager by Friday of

their intent to work on any immediately following Saturday or Sunday. Delays to project

completion experienced during holidays or weekends without proper permission or notice

will not be considered to be the responsibility of the City or Construction Manager.

Schedules shall be realistic. Contractors shall be required to show use of all calendar days

allowed for completion in their schedule or accept a no cost change order reducing the

number of days allowed for the completion of the work to the amount shown on the

proposed and approved schedule.

1.03 SUBMITTAL PROCEDURES

Within 20 days after the date of the Notice of Proceed, the Contractor shall complete a

construction schedule conforming to Part 1.02, Description, and representing in detail all

planned procurement and onsite construction activities. The schedule shall be prepared on

reproducible paper and may be in draft form with legible freehand lines and lettering. The

Contractor shall submit the original and three copies to the Construction Manager in

accordance with Section 01300, SUBMITTALS.

No progress payments shall be made prior to the acceptance of the CPM schedule. Failure

to resubmit updated schedules as required herein shall result in an increase in the retentions

of the amounts due the Contractor as described in these contract documents.

Within 14 calendar days after receipt of the submittal, the Construction Manager shall

review the submitted schedule and return two copies of the marked up original to the

Contractor. If the Construction Manager finds that the submitted schedule does not comply

with specified requirements, the corrective revisions will be noted on the submittal copy

returned to the Contractor for corrections and resubmittal as specified in Section 01300,

SUBMITTALS.

1.04 SCHEDULE REVISIONS

Revisions to the accepted construction schedule may be made only with written approval

of the Contractor and the City. Changes in timing for activities which are not on the critical

path may be modified with written agreement of the Contractor and Construction Manager.

A change affecting the timing of any activity on the critical path, the completion time and

specific dates and work sequencing may be made only with the approval of the

Construction Manager and the City.

1.05 PROJECT STATUS UPDATE

A jobsite meeting will be held each month at a time mutually agreed upon by the

Contractor, Construction Manager and City to review the construction progress for

compliance with the approved schedule. Weekly meetings will also be held between the

Contractor and Construction Manager to review the progress of the work of the previous

week and to coordinate the work of the subsequent week. The schedule shall be revised

12

whenever: the schedule does not represent the progress of the work; equipment submittals,

approvals or deliveries make rescheduling of activities necessary; any change to the

sequence of activities occurs or any change occurs to activities on the critical path; or when

a contract modification necessitates a revision to the schedule. Updates to the schedule

shall, at a minimum, be required on a monthly basis.

**END OF SECTION**

13

SECTION 01300

SUBMITTALS

PART 1 - GENERAL

1.01 GENERAL

Where required by the specifications, the Contractor shall submit descriptive information

which will enable determination of whether the Contractor's proposed materials,

equipment, or methods of work are in general conformance to the design concept and in

compliance with the drawings and specifications. The information to be submitted shall

consist of drawings, specifications, descriptive data, certificates, samples, test results and

such other information, all as specifically required in the specifications. In some instances,

specified submittal information describes some, but not all, features of the material

equipment, or method of work. Features not requiring submittals shall be as specified.

Submittal review shall be only for general conformance with the design concept and

general compliance with the information given in the contract documents. It shall not

include review of quantities, dimensions, weights or gages, fabrication processes,

construction safety precautions, all of which are the sole responsibility of the Contractor.

Review of a specific item shall not indicate acceptance of an assembly of which the item is

a component. The Engineer shall not be required to review, and shall not be responsible

for, any deviations from the contract documents not clearly noted by the Contractor, nor

shall the Engineer be required to review partial submissions or those for which submissions

for correlated items have not been received.

The Contractor may authorize material or equipment suppliers to deal directly with the

Engineer with regard to such submittals; however, ultimate responsibility for the accuracy

and completeness of the information contained in the submittal shall remain with the

Contractor.

1.02 CONTRACTOR'S RESPONSIBILITIES

The Contractor shall be responsible for the accuracy and completeness of the information

contained in each submittal and shall assure that the material, equipment, or method of

work shall be described in the submittal. The Contractor shall verify that all features of all

products conform to the requirements of the specifications and drawings. The Contractor

shall verify that all features of all products conform to the requirements of the

specifications and drawings. The Contractor shall insure that there is no conflict with other

submittals and shall notify the Engineer in each case where his submittal may affect the

work of City or others. The Contractor shall insure coordination of submittals among the

related crafts and subcontractors.

Immediately following Award of the Contract, the Contractor shall review the plans and

specifications and shall prepare a list of all submittals anticipated on the project and shall

14

submit this list to the Engineer. Items not on the list but requiring review shall be added to

the list as requested by the Engineer at any time during the construction.

1.03 TRANSMITTAL PROCEDURE

A. General

Submittals regarding material and equipment shall be accompanied by a transmittal form.

A separate form shall be used for each specific item, class of material, equipment, and for

items specified in separate, discrete sections. Submittals for various items shall be made

with a single form when the items taken together constitute a manufacturer's package or are

so functionally related that expediency indicates checking or review of the group or

package as a whole.

A unique number, sequentially assigned, shall be noted on the transmittal form

accompanying each item submitted. Submittal numbers shall have the following format:

"XXX-YYYYY-ZZ"; where "XXX" is the sequential number assigned by the Contractor,

"YYYYY" is the specification section number covered by the submittal, and "ZZ" is the

sequential number of the submittal ("01" for the first submittal, "02" for the second

submittal, etc.). Resubmittals shall have the same submittal number format; where "XXX"

is the originally assigned submittal number.

Submittal 25-11350-02, for example, would be the second submittal (first resubmittal) of

submittal 25 covering Section 11350.

B. Deviation from Contract

If the Contractor proposes to provide material, equipment, or method of work which

deviates from the contract documents, he shall so indicate on the transmittal form

accompanying the submittal copies.

C. Submittal Completeness

Submittals which do not contain all the information required to be submitted, including

deviations, are not acceptable and will be returned without review.

D. Requests for Substitution

The Contractor may offer material or equipment of equal or better quality and performance

in substitution for those specified. The City will consider offers for substitution only from

the Contractor and will not acknowledge or consider such offers from suppliers,

distributors, manufacturers, or subcontractors. The Contractor's offers of substitution shall

be made in writing to the Engineer and shall include sufficient data to enable the Engineer

to assess the acceptability of the material or equipment for the particular application and

requirements.

If the offered substitution necessitates changes to or coordination with other portions of the

work, the data submitted shall include drawings and details showing such changes.

15

Contractor agrees to perform these changes as part of the substitution of material or

equipment at no additional cost to City. Within 21 calendar days after receipt of the offer

of substitution, the Engineer will review the material submitted by the Contractor and

advise the Contractor of objections, if any, to the proposed substitution or if further

information is required. Upon notification by the Engineer, the Contractor shall either

provide material or equipment which complies with project specifications or furnish

requested additional information. While the Engineer might not take any objections to the

proposed substitution, such action shall not relieve the Contractor from responsibility for

the efficiency, sufficiency, quality and performance of the substitute material or equipment,

in the same manner and degree as the material and equipment specified by name. Any cost

differential associated with a substitution shall be reflected in the offer and the contract

documents shall be modified by a change order.

1.04 REVIEW PROCEDURE

When the contract documents require a submittal, the Contractor shall submit copies of the

specified information as follows unless otherwise specified:

A. One reproducible original of all the submitted information. When individual sheets in

the submittal exceed 8 1/2" x 11", a sepia shall be submitted.

B. Five copies of all the submitted information.

C. Submittals shall be delivered or mailed to:

The Construction Manager (To be determined)

Unless otherwise specified, within 21 calendar days after receipt of the submittal, the submittal

will be reviewed and three copies of the marked-up reproducible original will be returned to the

Contractor. The reproducible original shall be retained by the Engineer. The returned submittal

shall indicate one of the following actions:

A. If the review indicates that the material, equipment, or work method is in general

conformance with the design concept and complies with the drawings and specifications,

submittal copies will be marked "NO EXCEPTIONS TAKEN." In this event, the

Contractor may begin to implement the work method or incorporate the material or

equipment covered by the submittal.

B. If the review indicates limited corrections are required, copies will be marked "MAKE

CORRECTIONS NOTED." The Contractor may begin implementing the work method or

incorporating the material and equipment covered by the submittal in accordance with the

noted corrections. Where submittal information will be incorporated in operation and

maintenance information, a corrected copy shall be provided.

C. If the review reveals that the submittal is insufficient or contains incorrect data, copies will

be marked "REVISE AND RESUBMIT." Except at his own risk, the Contractor shall not

undertake work covered by this submittal until it has been revised, resubmitted and

returned marked either "NO EXCEPTIONS TAKEN" or "MAKE CORRECTIONS

16

NOTED."

D. If the review indicates that the material, equipment, or work method is not in general

conformance with the design concept or in compliance with the drawings and

specifications, copies of the submittal will be marked "REJECTED". Submittals with

deviations which have not been identified clearly may be rejected. Except at his own risk,

the Contractor shall not undertake the work covered by such submittals until a new

submittal is made and returned marked either "NO EXCEPTIONS TAKEN" or "MAKE

CORRECTIONS NOTED".

Following the initial review, two "resubmittals" will be allowed by the Engineer prior to a

"backcharge" for engineering review and administration costs being incurred by the

Contractor. The "backcharge" will be deducted from any amounts due the Contractor.

1.05 EFFECT OF REVIEW OF CONTRACTOR'S SUBMITTALS

Review of drawings, methods of work, or information regarding materials or equipment the

Contractor proposes to provide shall not relieve the Contractor of his responsibility for

errors therein and shall not be regarded as an assumption of risks or liability by the City, or

by any officer or employee thereof, or by any engineering firm conducting such review on

behalf of the City, and the Contractor shall have no claim under the contract on account of

the failure, or partial failure, of the method of work, material, or equipment so reviewed. A

mark of "NO EXCEPTIONS TAKEN" or "MAKE CORRECTIONS NOTED" shall mean

that the City has no objection to the Contractor, upon his own responsibility, using the plan

or method of work proposed, or providing the materials or equipment proposed.

PART 2 - PRODUCTS

2.1 PRELIMINARY SCHEDULE OF VALUES

A. The CONTRACTOR shall submit a preliminary Schedule of Values for the major

components of the WORK at the Preconstruction Conference. The listing shall include a

detailed breakdown of cost for each lump sum bid item specified in Section 01025,

MEASUREMENT AND PAYMENT.

The CONTRACTOR and CONSTRUCTION MANAGER shall meet and jointly review the

preliminary Schedule of Values, and make any adjustments in value allocations if, in the

opinion of the CONSTRUCTION MANAGER, these are necessary to establish fair and

reasonable allocation of values for the major components of the WORK. Front end loading

of the Schedule of Values will not be permitted. The CONSTRUCTION MANAGER may

require reallocation of major WORK components from items in the above listing if such

reallocation is necessary in the opinion of the CONSTRUCTION MANAGER.

2.2 DETAILED SCHEDULE OF VALUES

A. The CONTRACTOR shall prepare and submit a detailed Schedule of Values to the

CONSTRUCTION MANAGER within 15-days from acceptance of preliminary schedule of

values that is submitted within 15-days of NTP per 3.1 A this section. The detailed Schedule

of Values shall be based on the accepted preliminary Schedule of Values for major

components of the WORK. Sufficient breakdown of the construction activities shall be

provided to allow development of a detailed Schedule of Values sufficient to determine

appropriate monthly progress payment amounts through cost loading of the Construction

Schedule activities. The CONSTRUCTION MANAGER shall determine the acceptable

numbers, details and description of values established. If, in the opinion of the

CONSTRUCTION MANAGER, a greater number of items or construction activities than

those proposed by the CONTRACTOR are necessary, the CONTRACTOR shall add the

additional items so identified by the CONSTRUCTION MANAGER.

1. The minimum detail of breakdown of the major components of the WORK is indicated

in Part 1 of Section 01025 Measurement and Payment. Greater detail shall be provided

as directed by the CONSTRUCTION MANAGER.

a. All other WORK not specifically included in the above items shall be detailed as

necessary for establishment of cost and Construction Schedule activity items.

The CONTRACTOR and CONSTRUCTION MANAGER shall meet and jointly

review the detailed Schedule of Values within 35-days from the date of Notice to

Proceed. The value allocations and extent of detail shall be reviewed to determine any

necessary adjustments to the values and to determine if sufficient detail has been

proposed to provide cost loading of the Construction Schedule activities.

19

2. Following acceptance of the detailed Schedule of Values, the CONTRACTOR shall

incorporate the values into the cost loading portion of the Construction Schedule. The

Construction Schedule activities and logic shall have been developed concurrent with

development of the detailed Schedule of Values; however, it shall be necessary to

adjust the detailed Schedule of Values to correlate to individual Construction Schedule

activities. Because of the independent but simultaneous development of the Schedule

of Values and the Construction Schedule activities, it is anticipated that instances will

occur where interfacing these two documents will require changes to both documents.

Construction Schedule activities may need to be added to accommodate the detail of the

Schedule of Values. Schedule of Value items may need to be added to accommodate

the details of the Construction Schedule activities. Where such instances arise, the

CONTRACTOR shall propose changes to the Schedule of Values and to the

Construction Schedule activities acceptable to the CONSTRUCTION MANAGER to

satisfy the Construction Schedule cost loading requirements.

2.3 CROSS REFERENCE LISTING

A. To assist in the correlation of the Schedule of Values and the Construction Schedule, the

CONTRACTOR shall provide a Cross Reference Listing which shall be furnished in two

parts. The first part shall list each Scheduled Activity with the breakdown of the respective

valued items making up the total cost of the activity. The second part shall list the valued

item with the respective Scheduled Activity or Activities that make up the total cost

indicated. In the case where a number of schedule activities make up the total cost for a

valued item (shown in the Schedule of Values) the total cost for each scheduled activity

should be indicated.

B. These listings shall be updated and submitted in conjunction with the Construction Schedule

monthly submittals as stated in Section 01310, CONSTRUCTION SCHEDULE.

C. Approved change orders reflected in the Construction Schedule shall be incorporated into the

Schedule of Values as a single unit identified by the change order number.

2.4 CHANGES TO SCHEDULE OF VALUES

A. Changes to the Construction Schedule, which add activities not included in the original

schedule but included in the original WORK (schedule omissions), shall have values

assigned, and other activity values shall be reduced to provide equal value adjustment

increases for added activities as approved by the CONSTRUCTION MANAGER.

B. In the event that the CONTRACTOR and CONSTRUCTION MANAGER agree to

make adjustments to the original Schedule of Values because of inequities discovered

in the original accepted detailed Schedule of Values, increases and equal decreases to

values for activities may be made.

1.01 DESCRIPTION

This section specifies the installation, testing, and commissioning for all mechanical,

electrical and instrumentation systems.

1.02 QUALITY ASSURANCE

A. Installation

All mechanical, electrical, and instrumentation equipment provided under this contract

shall be installed in conformity with the details shown and specified and with the

manufacturer's requirements. Should a manufacturer's installation recommendations

conflict with specific requirements of these contract documents, the Contractor shall

bring the matter to the attention of the Construction Manager. Any additional costs

incurred arising out of changes in the contract documents authorized by the

Construction Manager to accommodate manufacturer's installation recommendations

will be considered extra work in accordance with the General Conditions. Any costs

incurred by the Contractor through failure to timely notify the Construction Manager of

a difference between contract document and manufacturer's installation requirements

shall be borne by the Contractor.

B. Testing

1. General Requirements: All equipment and partially complete or fully completed

portions of the work included in this contract shall be tested and inspected to

to make the equipment operate as specified shall be carried out by the

Contractor as part of the work.

9. Procedures:

Prior to receipt of any progress payments in excess of 60% of the Contractor's

lump sum bid for the work, the Contractor shall submit to the Construction

Manager, in quintuplicate, details of the installed tests and inspection

procedures he proposes to adopt for testing and start-up of all equipment to be

operated singly and together, except when such procedures have been

addressed in the Project Specifications. The procedures shall be divided into

two distinct stages: pre-operation checkout and operation testing. Testing

procedures shall be designed to duplicate, as nearly as possible, all conditions

of operation and shall be carefully selected to ensure that the equipment is not

damaged. Once the testing procedures have been reviewed by the

Construction Manager, the Contractor shall produce checkout, alignment,

adjustment and calibration signoff forms for each item of equipment to be

used in the field by the Contractor and the Construction Manager jointly to

ensure that each item of electrical, mechanical, and instrumentation equipment

has been properly installed and tested. The Contractor is advised that failure to

observe these precautions may place the acceptability of the subject

equipment in question.

10. Preoperation Checkout: The installed tests and inspection procedures shall

incorporate all requirements of these specifications and shall proceed in a

logical, step wise sequence to ensure that all equipment has been properly

serviced, aligned, connected, calibrated and adjusted prior to operation.

Preoperation checkout procedures shall include, but not necessarily be limited

to:

a. Piping system pressure testing and cleaning as specified in

Division 15, MECHANICAL.

b. Alignment of equipment.

c. Preoperation lubrication.

11. Operational Testing: Once all affected equipment has been subjected to the

required preoperational checkout procedures and the Construction Manager

has witnessed and has not found deficiencies in that portion of the work,

individual systems may be started and operated under simulated operating

conditions to determine as nearly as possible whether the equipment and

systems meet the requirements of these specifications. Potable water shall be

employed for the testing of all liquid systems except gaseous, oil or chemical

systems unless specified otherwise. Test media for these systems shall either

be the intended fluid or a compatible substitute. The equipment shall be

operated a sufficient period of time to determine machine operating

characteristics, including temperatures and vibration; to observe performance

characteristics; and to permit initial adjustment of operating controls. When

testing requires the availability of auxiliary systems such as electrical power,

compressed air, control air, or instrumentation which have not yet been placed

in service, the Contractor shall provide acceptable substitute sources, capable

of meeting the requirements of the machine, device or system, at no additional

cost to the City. Disposal methods for test media shall be subject to review

and acceptance of the Construction Manager.

12. Repeated Tests: If under test, any portion of the work should fail to fulfill the

contract requirements and is adjusted, altered, renewed or replaced, together

with all other portions of the work as are affected thereby, shall, if so required

by the Construction Manager, be repeated within reasonable time and in

accordance with the specified conditions. The Contractor shall pay to the City

all reasonable expenses incurred by the City as a result of repeating such tests.

Once simulated operation has been completed, all machines shall be

rechecked for proper alignment, realigned, if necessary, and doweled in place.

All equipment shall be checked for loose connections, unusual movement or

other indications of improper operating characteristics. Any deficiencies shall

be corrected to the satisfaction of the Construction Manager. All machines or

devices which exhibit unusual or unacceptable operating characteristics shall

be disassembled and inspected. They shall then be repaired or removed from

the site and replaced at no cost to the City.

13. Tolerances: Test results shall be within the tolerances set forth in the detailed

specification sections of this contract document. If no tolerances have been

specified, test results shall conform to tolerances established by recognized

industry practice. Where, in the case of an otherwise satisfactory installed test,

any doubt, dispute, or difference should arise between the Construction

Manager and the Contractor regarding the test results or the methods or

equipment used in the performance of such test, then the Construction

Manager may order the test to be repeated. If the repeat test, using such

modified methods or equipment as the Construction Manager may require,

substantially confirms the previous test, then all costs in connection with the

repeat test will be paid by the City, otherwise the costs shall be borne by the

Contractor. Where the results of any installed test fail to comply with the

contract requirements for such test, then such remedial efforts and repeat tests

as may be necessary to achieve the contract requirements shall be made by the

Contractor at this expense.

14. Contractor Supplied Materials: Unless otherwise specified, the Contractor

shall provide at no expense to the City, all power, fuel, compressed air

supplies, labor and all other necessary items and work required to complete all

tests and inspection specified herein. The Contractor shall provide, at no

expense to the City, temporary heating, ventilating and air conditioning for

any area requiring it in the case where permanent facilities are not complete

and operable at the time of installed tests and inspections. Temporary facilities

shall be maintained until permanent systems are in service.

15. Commissioning: After completion of the operation testing and certification by

the Construction Manager that the systems did meet all performance

requirements, commissioning will begin. The commissioning period for each

system or system components shall be 15 days except where specified

otherwise specified. The Contractor shall remove all temporary piping or

bulkheads that may have been in use during the operational testing. The City's

operations and maintenance personnel will be responsible for operation of the

plant or portion of the plant being operated during this period of time. The

plant or portion thereof shall be fully operational, accepting all normal flow

called for in design and performing all functions as designed. The Contractor

and the equipment manufacturer's technical representative shall be available at

all times during the commissioning period to provide immediate assistance in

case of failure of any portion of the system being tested. At the end of the

commissioning period and when all corrections required by the Construction

Manager to assure a reliable and completely operational facility are complete,

the Construction Manager shall issue a certificate of substantial completion.

During the commissioning period, the City shall be responsible for all normal

operational costs and the Contractor shall bear the costs of all necessary

repairs or replacements, including labor and materials, required to keep the

portion of the plant being commissioned, operational.

16. Training: During the operational testing phase of equipment, the Contractor

shall make available experienced factory trained representatives of the

manufacturers of all the various pieces of equipment, to train the City's

personnel in the operation and maintenance thereof. The time required for this

training shall be as specified herein for the specific piece of equipment. The

PART 3 - EXECUTION

3.01 GENERAL

A. Control of Water

The Contractor shall keep excavations free from water during construction. The static water

level shall be drawn down a minimum of 2 ft. below the bottom of excavations to maintain

the undisturbed state of natural soils and allow the placement of any fill to the specified

density. Disposal of water shall not damage property or create a public nuisance. The

Contractor shall have on hand pumping equipment and machinery in good working condition

for emergencies and shall have workers available for its operation. Dewatering systems shall

operate continuously until backfill has been completed to 1 ft. above the normal static

groundwater level. The location of the Contractor's dewatering discharge shall be approved

by the Engineer.

Groundwater shall be controlled to prevent softening of the bottom of excavations, or

formation of "quick" conditions. Dewatering systems shall not remove natural soils.

Release of groundwater to its static level shall be controlled to prevent disturbance of the

natural foundation soils or compacted fill and to prevent flotation or movement of structures

of pipelines.

Additional dewatering requirements are specified in Section 02140, DEWATERING.

Dewatering piping which crosses existing roads shall be buried.

Contractor shall be responsible for constructing and maintaining a temporary desilting basin

to allow the water removed from trenches to pass through prior to discharge.

B. Shoring and Sheeting

Shore and sheet excavations over 5 ft. in depth in accordance with Section 02160,

EXCAVATION SUPPORT SYSTEMS.

C. Hauling

When hauling is done over highways or city streets, the loads shall be trimmed and the

vehicle shelf areas shall be cleaned after each loading. The loads shall be watered after

trimming to eliminate dust. All streets shall be swept clean daily where dirt and debris result

from the Contractor's operation.

D. Maintenance of Roadways

All earthwork operations shall be performed in a manner which does not disrupt the

continuous flow of traffic on existing roadways without prior approval of the Engineer.

E. Control of Erosion

The Contractor shall maintain earthwork surfaces true and smooth and protected from

erosion. Where erosion occurs, the Contractor shall provide fill or shall excavate as

necessary to return earthwork surfaces to the grade and finish specified.

F. Surplus Material

Surplus excavated material shall become the property of the Contractor and shall be disposed

of at the Contractor’s expense.

Material shall not be stockpiled to a depth greater than 5 feet above the finished grade within

25 feet of any excavation or structure. The contractor shall maintain stability of all

stockpiled materials.

The Contractor shall satisfy himself that there is sufficient material available for the

completion of the work before disposing of any material inside or outside the site. Shortage

of material, caused by premature disposal of any material by the Contractor, shall be replaced

by the Contractor at his expense.

G. Pavement, Curb, And Sidewalk Removal

Cut all bituminous and concrete pavements, regardless of the thickness, and all curbs and

sidewalks, prior to excavation of the trenches with an approved pavement saw.

Hydrohammers will be prohibited. Pavement shall be sawed completely through on neat

lines parallel and equidistant from the trench centerline. Sawcuts shall be a minimum of 12

in. wider on each side of the actual trench width for asphalt concrete pavements and a

minimum of 6 inches wider than the trench width for concrete pavements. Pavement and

concrete materials removed shall be hauled from the site and disposed of as specified in

Section 02100, SITE PREPARATION.

H. Excavation of Rock

If rock is encountered, notify the Engineer immediately. The Engineer will determine if the

material meets the definition of rock as specified herein. The Engineer will then instruct the

Contractor to relocate portions of the work to avoid the rock or will instruct the Contractor to

excavate the rock. Blasting shall only be conducted following written approval of the

Engineer.

I. Hazardous Waste

Contractor shall promptly notify the Engineer in writing, of any subsurface material that

Contractor believes is hazardous, as defined in Section 25117 of the Health and Safety Code.

Upon discovery, material is to remain undisturbed until an investigation can be made by the

Engineer.

3.02 EXCAVATION AND FILL—GENERAL EARTHWORK

A. Excavation

Excavation shall be to the elevations and dimensions indicated. Notify the Engineer

immediately in writing in the event that it becomes necessary to remove hard, soft, weak, or

wet material to a depth greater than indicated.

Soil disturbed or weakened by the Contractor's operations and soils permitted to soften from

exposure to weather shall be excavated to firm foundation and refilled with engineered fill

material compacted to 90% of ASTM D1557, Method D, maximum density. All work of this

nature will be at the Contractor's expense.

B. Overexcavation

Subgrade soils beneath operations building and package plant slab (42’ by 87’) shall be

overexcavated to a five-foot minimum depth below the slab. The zone of overexcavation

shall extend horizontally at least 5 ft outside the perimeter edges of structure.

Overexcavated soils shall be replaced with Type 1 Engineered Fill.

C. Filling Operations

1. Subgrade for Engineered Fill

All areas to receive engineered fill shall be prepared as specified herein.

For subgrades composed of undisturbed bedrock which is also classified as competent

material, the subgrade shall be left undisturbed.

For subgrades not composed of competent bedrock the surface to receive engineered fill

shall be scarified to a depth of 24 in., moisture conditioned, and compacted in 8 inch

lifts as specified in Section 3.05.

2. Proof-Rolling

Unless otherwise directed in writing by the Engineer proof-roll all subgrade surfaces,

except undisturbed bedrock, prior to constructing engineered fill. Use a half loaded

dump truck or similar heavy-wheeled vehicle acceptable to the Engineer to detect soft or

loose zones. Notify the Engineer prior to commencement of proof-rolling. If soft or

loose zones are found, excavate the soft or loose material to a depth directed by the

Engineer, then fill and compact as specified for engineered fill. The quantity and

placement of such material will be paid for as extra work.

3. Construction of Engineered Fill

Construct engineered fill to lines and cross sections shown. Deposit fill material in lifts

not exceeding 8 inches in loose depth, moisture condition, and compact as specified in

Section 3.05.

No fill shall be placed during weather conditions which will alter the moisture content

of the fill materials sufficiently to make adequate compaction impossible. After placing

operations have been stopped because of adverse weather conditions, no additional fill

material shall be placed until the last layer compacted has been checked and found to be

compacted to the specified densities.

Care should be taken during fill placement to prevent and/or correct any unstable or

"pumping" subgrade conditions. Such conditions could develop with a combination of

factors, including overly moist soils, heavy construction, equipment or frequent

movement of equipment. If an unstable or "pumping" condition should develop as

determined by the Engineer, the affected soils shall be removed and replaced or aerated

and allowed to stabilize prior to further work in the area. Furthermore, when, in the

judgment of the Engineer, sufficient compaction effort has not been used or where the

field density tests indicate that the required compaction or moisture content has not been

obtained, the fill shall be reworked and recompacted as needed to obtain a stable fill at

the required density and moisture content prior to placing additional fill materials.

The Contractor shall be responsible for the maintenance and protection of all

embankments and fills made during the contract period and shall bear the expense of

replacing any portion which has been displaced due to carelessness, negligent work,

erosion or failure to take proper precautions.

3.03 EXCAVATION AND BACKFILL – PIPELINES AND UTILITIES

A. Excavation

1. General

Pipelines and utilities shall be installed in trenches. Excavation shall include the

satisfactory loosening, removing, loading, stockpiling, transporting, and

placement in final location (including disposal) of all materials necessary to for

construction of trenches. Trench excavation shall include the removal of all

materials and/or obstructions of any nature.

2. Trenching

Minimum trench width for piping shall be the outside diameter of the piping plus

18 inches. For duct banks the minimum width shall be three inches wider than the

outside edges of the conduit bank. Maximum trench widths at the top of the pipe

shall be as shown on the Drawings for the designated type bedding. For drainage

pipe, if no maximum is shown, the Contractor shall limit top trench widths to pipe

outside diameter plus 24 inches for pipe 24 inches or smaller, and pipe outside

diameter plus 36 inches for pipe 27 inches and larger, except upon written

approval of a wider trench by the Engineer.

If, because of soil conditions, safety requirements or other reasons, the trench

width at top of pipe is increased beyond the width specified in the preceding

paragraphs, laying conditions shall be upgraded or stronger pipe installed,

designed in conformance with the specifications for the increased trench width,

without additional cost to the Owner.

3. Manholes, Valves And Appurtenances

Excavation for manholes, valves, or other accessories shall be sufficient to leave

at least 12 inches in the clear between their outer surfaces and the trench side,

trench shield or shoring. Backfill under manholes, vaults, tanks, or valves shall

be imported material as designated on the drawings. Any unauthorized excess

excavation below the elevation indicated for foundation of any structure shall be

filled with sand, base material, or concrete, at the direction of the Engineer, and at

the expense of the Contractor. Backfilling of manhole excavation shall conform

to the backfilling required for trenches.

4. Location Of Excavated Materials

During trench excavation, place the excavated material only within the approved

working area. Do not obstruct any roadways or streets unless specified otherwise.

Conform to all Federal, State, and local codes governing the safe loading of all

trenches with excavated material.

Material shall not be stockpiled greater than 5 feet above grade within 25 feet of

any excavation.

5. Overexcavation

Where the undisturbed condition of natural soils is inadequate for support of the

planned construction, the Engineer will direct the Contractor to overexcavate to

adequate supporting soils. The excavated space shall be filled to the specified

elevation with bedding. The quantity and placement of such material will be paid

for as follows:

1. Overexcavation and refilling up to 12 inches below the specified trench

bottom elevation shall be solely the Contractor's responsibility and expense.

2. Overexcavation and refilling in excess of 12 inches below the specified trench

bottom elevation will be considered extra work.

B. Backfill

1. General

Construct backfill as indicated and specified in this section. Place backfill in 8 in.

maximum loose lifts unless otherwise specified. Bring up evenly on each side

and along the full length of the pipe. Ensure that no damage is done to structures,

pipe or their protective coatings. Compact each loose lift as specified in

Subsection 3.05, Compaction, before placing the next lift. Do not backfill in

freezing weather or where the material in the trench is already frozen or is muddy,

except as authorized.

Where settlements occur in trenches due to improper compaction, the Contractor

shall excavate to the depth necessary to rectify the problem, then backfill,

compact as specified herein, and restore the surface to the required elevation. If

pavement is damaged, it shall be removed after carefully sawcutting the damaged

area, and replaced as originally specified. All costs of repairing settlement and

related damage shall be borne by the Contractor.

2. Bedding and Initial Backfill

The pipe shall be placed on a bed of imported materials. All loose material shall

be removed from the trench bottom before placing the bedding material. Bedding

shall extend at least 4 inches below the pipe barrel (6 inches for a pipe greater

than 6 inches in diameter) and 1-1/2 inches below the pipe joint bell. No wedging

or blocking of the pipe will be permitted. The pipe shall be bedded uniformly

throughout its length. The bearing shall be achieved by shaping the bedding or by

lightly "bouncing" the pipe to set it into the bedding.

The Contractor shall then place initial backfill material. Each lift shall be worked

under the haunches of the pipe and thoroughly compacted to the specified

compaction by shovel slicing, tamping and other appropriate means to achieve a

dense and thoroughly compacted material that provides proper support under the

pipe haunches. Care shall be used not to disturb or displace the pipe. Initial

backfill shall be the material placed from the top of the bedding to a point 12

inches above the top of the pipe and pipe bell. Initial backfill shall be carefully

placed evenly on both sides of the pipe so as not to disturb or damage the pipe,

and compacted to the specified compaction. Jetting will not be allowed.

3. Subsequent Backfill

Subsequent trench backfill above the initial backfill shall be placed and

compacted as specified. Jetting will not be allowed. However, until the total

backfill above the top of the pipe exceeds 3 feet, machine-placed backfill material

shall not be allowed to "free-fall" more than 2 feet. If the excavation is through

an area used for horticulture, lawns or other cultivated areas, the final 12 inches of

backfill shall be essentially the original topsoil which shall have been removed

and stockpiled separately.

4. Finish Grading

Finished surfaces shall be smooth, compacted and free from irregularities. The

degree of finish shall be that normally obtainable with a blade-grader.

Finished grade shall be as specified by the contours plus or minus 0.10 feet except

where a local change in elevation is required to match sidewalks, curbs, manholes

and catch basins, or to ensure proper drainage. Allowance for topsoil and grass

cover, and subbase and pavement thickness shall be made.

5. Buried Warning and Identification Tape

Install tape specified in Section 15060, PIPING SYSTEMS, above all buried

pipes and conduits in accordance with manufacturer's recommendations except as

modified herein. Bury tape 12 inches below finished grade; under pavements and

slabs, bury tape 6 inches below top of subgrade.

6. Open Trench

The Contractor shall not leave trenches open during hours when the Contractor is

not actively working. All trenches shall be backfilled at the end of the day or up

to 200 feet may be left shored and plated.

3.04 EXCAVATION AND BACKFILL -- STRUCTURES

General

The bottom excavation elevation shall be sufficient to allow the proper placing of

forms and concrete construction to the elevations indicated, as specified herein.

Slopes shall vary no more than 0.5 ft from specified grade.

Overexcavation

Subgrade soils beneath all structures shall be overexcavated to the depth specified

in Subsection 3.02, Excavation and Fill--General; Item B, Overexcavation. After

the overexcavation is complete, the Contractor shall scarify the top 12 in. and

recompact the subgrade in accordance with Subsection 3.05, Compaction. The

excavated space shall be filled as specified for Type I Engineered Fill.

Should the excavation be carried below the elevation required per the contract

documents or should the bottom of the excavation be disturbed because of the

Contractor’s operations and require overexcavation and backfill, the Contractor

shall refill such excavated space to the proper elevation in accordance with the

procedure specified for Type I Engineered Fill at his expense.

Unless otherwise specified, excavation shall extend a sufficient distance from

walls and footings to allow for placing and removal of forms, installation of

services, and for inspection, except where concrete is specified to be placed

directly against excavated surfaces.

Foundation Inspection

Whenever any structure excavation is substantially completed to grade, the

Contractor shall notify the Engineer who will make an inspection of the

foundation for uniformity and suitability as a structure foundation. No concrete

or masonry shall be placed until the foundation has been inspected by the

Engineer. The Contractor shall, if directed by the Engineer, dig test pits and make

test borings and foundation bearing tests. If the material tested complies with the

specifications, the cost thereof will be paid for as extra work. If the material

tested does not comply with the specifications, the cost thereof (initial testing,

remedial work, re-testing) will be borne by the Contractor.

Backfilling and Filling

1. Structural Backfill

Unless otherwise specified, structural backfill shall be Type I Engineered

Fill.

After completion of construction below the elevation of the final grade,

and prior to backfilling, forms shall be removed and the excavation shall

be cleaned of debris.

Structure backfill shall not be placed until the subgrade portions of the

structure have been inspected by the Engineer. No backfill material shall

be deposited against concrete structures until the concrete has developed

the specified 28 day compression strength, and until the concrete has been

in place for 14 days, whichever occurs last. Backfill material shall be

placed in uniform layers (8 in. thick) and shall be brought up uniformly on

all sides of the structure. Each lift shall be compacted in accordance with

Subsection 3.05, Compaction.

2. Structural Foundation Fill

Where fill materials form the foundation for a structure, materials shall be

Crushed Rock, Drain Rock, Rock Capillary Break, or Type I Engineered

Fill as shown on the plans. Materials shall be placed in 8 in. lifts and

compacted in accordance with Subsection 3.05, Compaction.

3.05 COMPACTION

Compact each layer or lift of material specified so that the in-place density tested is not less

than the percentage of maximum density identified herein per ASTM D1557. Compaction

shall be accomplished by mechanical equipment such as tamping rollers, sheepsfoot rollers,

pneumatic tire rollers, vibrating rollers, or other mechanized tampers suitable for the work.

Compaction of materials by ponding and jetting is prohibited.

Compaction methods and equipment used are subject to approval by the Engineer.

minimum of 6 inches wider than the trench width for concrete pavements. Pavement and

concrete materials removed shall be hauled from the site and disposed of as specified in

Section 02100, SITE PREPARATION.

3.03 BACKFILL

A. General

Construct backfill as indicated and specified in this section. Place backfill in 8 in.

maximum loose lifts unless otherwise specified. Bring up evenly on each side and along

the full length of the pipe. Ensure that no damage is done to structures, pipe or their

protective coatings. Compact each loose lift as specified below before placing the next

lift. Do not backfill in freezing weather or where the material in the trench is already

frozen or is muddy, except as authorized.

Where settlements occur in trenches due to improper compaction, the Contractor shall

excavate to the depth necessary to rectify the problem, then backfill, compact as specified

herein, and restore the surface to the required elevation. If pavement is damaged, it shall

be removed after carefully sawcutting the damaged area, and replaced as originally

specified. All costs of repairing settlement and related damage shall be borne by the

Contractor.

B. Bedding and Initial Backfill

The pipe shall be placed on a bed of imported materials. All loose material shall be

removed from the trench bottom before placing the bedding material. Bedding shall

extend at least 4 inches below the pipe barrel (6 inches for a pipe greater than 6 inches in

diameter) and 1-1/2 inches below the pipe joint bell. No wedging or blocking of the pipe

will be permitted. The pipe shall be bedded uniformly throughout its length. The bearing

shall be achieved by shaping the bedding or by lightly "bouncing" the pipe to set it into

the bedding.

The Contractor shall then place initial backfill material. Each lift shall be worked under

the haunches of the pipe and thoroughly compacted to the specified compaction by

shovel slicing, tamping and other appropriate means to achieve a dense and thoroughly

compacted material that provides proper support under the pipe haunches. Care shall be

used not to disturb or displace the pipe. Initial backfill shall be the material placed from

the top of the bedding to a point 12 inches above the top of the pipe and pipe bell. Initial

backfill shall be carefully placed evenly on both sides of the pipe so as not to disturb or

damage the pipe, and compacted to the specified compaction. Jetting will not be allowed.

C. Subsequent Backfill

Subsequent trench backfill above the initial backfill shall be placed and compacted as

specified. Jetting will not be allowed. However, until the total backfill above the top of

the pipe exceeds 3 feet, machine-placed backfill material shall not be allowed to "free-

fall" more than 2 feet. If the excavation is through an area used for horticulture, lawns or

other cultivated areas, the final 12 inches of backfill shall be essentially the original

topsoil which shall have been removed and stockpiled separately.

D. Finish Grading

Finished surfaces shall be smooth, compacted and free from irregularities. The degree of

working day will be permitted unless approved in writing by the Construction Manager.

All sharp edges, burrs and weld spatter shall be removed. The following levels of

surface preparation are subsequently referred to:

1. White Metal Blast Cleaning (SSPC-SP-5): Removal of all visible rust, mill scale,

paint, and foreign matter by blast cleaning by wheel or nozzle (dry) using sand,

grit, or shot.

2. Near-White Blast Cleaning (SSPC-SP-10): Blast cleaning nearly to white metal

cleanliness until at least 95% of each element of surface area is free of all visible

residues.

3. Commercial Blast (SSPC-SP-6): Blast cleaning until at least 67% of each element

of surface area is free of all visible residues.

4. Brush-Off Blast Cleaning (SSPC-SP-7): Blast cleaning of all except tightly

adhering residues of mill scale, rust, and coatings, exposing numerous evenly

distributed flecks of underlying metal.

5. Solvent Cleaning (SSPC-SP-1): Removal of all grease, oil and dirt.

Clean cloths and clean fluids shall be used in solvent cleaning. Cleaning and painting

shall be scheduled so that dust and spray from the cleaning process will not fall on wet,

newly painted surfaces. Hardware, electrical fixtures and similar accessories shall be

removed or masked during preparation and paint operations, or shall otherwise be

satisfactorily protected. Equipment adjacent to walls shall be disconnected and moved to

permit cleaning and painting of equipment and walls and, following painting, shall be

replaced and reconnected.

B. Metallic Surfaces

with a primer compatible with both the existing coating and the field applied paint, or

replaced with the proper prime coat. The primer shall be as recommended by the

manufacturer of the field applied paints.

The Contractor has the option of completely removing the existing coating before

applying the specified coating.

3.03 APPLICATION

A. Workmanship

Each coat of paint shall be of the consistency as supplied by the manufacturer, or

thinned if necessary, and applied in accordance with the manufacturer's written

instructions. Each coat shall be well brushed, rolled, or sprayed to obtain a uniform and

evenly applied finish. Work shall be free from "runs", "bridges", "shiners", or other

imperfections due to faulty intervals. Particular care shall be taken to obtain a uniform,

unbroken coating over all bolts, threads, nuts, welds, edges and corners. Further, all

weld splatter shall be removed and all welds neutralized with thinner.

B. Paint Properties, Mixing and Thinning

Paint, when applied, shall provide a satisfactory film and smooth even surface, and

glossy undercoats shall be lightly sanded to provide a surface suitable for the proper

application and adhesion of subsequent coats. Paints shall be thoroughly stirred,

strained, and kept at a uniform consistency during application. Coatings consisting of

two or more components shall be mixed in accordance with the manufacturer's

instructions. Unless otherwise specified, paint shall not be reduced more than necessary

to obtain the proper application characteristics. Thinner shall be both type and amount

as recommended by the coating manufacturer.

C. Environmental Conditions

Paints shall be applied only to surfaces that are dry, and only under such atmospheric

conditions as will cause evaporation rather than condensation. Paint shall not be applied

during rainy, misty weather, or to surfaces upon which there is frost or moisture

condensation. During damp weather, when the temperature of the surface to be coated is

within 5°F of the dew point, the surfaces shall be heated to prevent moisture

condensation thereon. Bare metal surfaces, except those which may be warped by heat,

may be dehydrated by flame-heating devices immediately prior to paint application.

During painting, and for a period of at least 8 hours after the paint has been applied, the

temperature of the surfaces to be painted, the painted surfaces, and the atmosphere in

contact shall be maintained at or above 50°F and not less than 10°F above the dew point

or specifically at manufacturer's recommended ambient temperatures and humidity

ranges. . Fans or heaters shall be used inside enclosed areas where conditions causing

condensation are severe.

Paint shall not be applied on surfaces hotter than 120°F.

No painting of concrete, masonry work, plaster or plasterboard is permitted until all

construction activities involving moisture in adjacent areas have been completed, the

moisture involved has been dissipated, and adjacent masses and the surface to be

painted have reached a constant condition of humidity suitable for the application of

paint.

Paint shall not be applied to masonry or concrete within 30 days of construction of same

or if the moisture content is greater than 15% as measured on the Delmhorst moisture

meter.

D. Protection of Coated Surfaces

Items which have been coated shall not be handled, worked on, or otherwise disturbed,

until the paint is completely dry and hard. After delivery at the site of permanent

erection or installation, shop-coated metalwork shall be repainted or retouched with

specified paint when it is necessary to maintain the integrity of the film.

E. Method of Paint Application

Where two or more coats are required, the alternate coats shall be of contrasting colors.

Colors shall not contain lead, or any lead compound, which may be destroyed or

affected by hydrogen sulfide or any other corrosive gas.

Electrical, instrumentation, and mechanical equipment, on which the manufacturer's

coating is acceptable, shall be touch-up primed and painted with two coats of the

specified coating system to match the color scheduled. This does not apply to electrical

and instrumentation equipment specified in Division 16.

Only good, clean brushes and equipment shall be used; and all brushes, buckets, and

spraying equipment shall be cleaned immediately at the end of each painting period.

If paint is applied by spray, the air pressure used shall be within the ranges

recommended by both the paint and spray equipment manufacturers. Spray painting

shall be conducted under controlled conditions, and the Contractor shall be fully

responsible for any damage occurring from spray painting.

Care shall be exercised not to damage adjacent work during abrasive blasting

operations. Stainless steel need not be abrasive blasted. Blasted surfaces shall be coated

as soon as possible after being abrasive blasted and before any rust bloom occurs. If rust

bloom occurs, abrasive blasting the surface must be repeated prior to coating. All dust

shall be removed from the surfaces prior to painting.

F. Film Thickness and Continuity

Coating system thickness is the total thickness of primer and finish coats and does not

include passivators or sealers.

The surface area covered per gallon of paint for various types of surfaces shall not

exceed those recommended by the manufacturer. The first coat (prime coat) on metal

surfaces refers to the first full paint coat and not to conditioning, tie coats, sealers or

other pretreatment applications. Coatings shall be applied to the thickness specified, and

in accordance with these specifications. Unless otherwise specified, the average total

thickness (dry) of any completed protective coating system on exposed metal surfaces

shall be not less than 1.25 mils per coat, and the minimum thickness at any point shall

not deviate more than 25% from the required average. Unless otherwise specified, no

less than 2 coats shall be applied.

In testing for continuity of coating about welds, projections (such as bolts and nuts), and

crevices, the Construction Manager will determine the minimum conductivity for

smooth areas of like coating where the dry mil thickness has been accepted. This

conductivity shall then be taken as the minimum required for those rough or irregular

areas. Pinholes and holidays shall be repainted to the required coverage.

G. Special Requirements

Hangers and supports shall be coated, except for the final coat, prior to the installation.

Except for those to be filled with grout, the underside of ungalvanized equipment bases

and supports shall be coated with at least one coat of primer specified for System C

prior to setting the equipment in place. Bolts and bolt holes in flanges (such as those

used with couplings or wafer type valves where holes and bolts as finally installed will

be exposed to weather or moisture) shall be coated prior to assembly to prevent rusting

of the unprotected metals.

H. Cleanup

Upon completion of coating, the Contractor shall remove surplus materials, protective

coverings, and accumulated rubbish, and thoroughly clean all surfaces and repair any

overspray or other paint related damage.

3.04 ELEVENTH MONTH INSPECTION

The Contractor shall guarantee all coating work for a period of one year following the

date of final acceptance by the City. The Contractor is hereby notified that the City will

inspect the project during the eleventh month following the date of final acceptance. The

Contractor shall be notified by certified letter as to the date and time of the eleventh

month inspection and will be expected to attend with his coating subcontractor. All

defects in workmanship and materials shall be repaired by the Contractor at no cost to

the City in accordance with this specification and to the satisfaction of the City or their

appointed representative.

PART 3 - EXECUTION

3.01 INSTALLATION

A. General

Plastic lining sheets to be installed on concrete surface poured with forms shall be

closely fitted and properly secured to the inner forms prior to any concreting operation.

Sheets shall be cut to fit curved and wrapped surfaces using a minimum numbers of

separate pieces. On vertical surfaces, liner sheets shall be placed so that locking ribs run

vertically. Where liner sheets terminate on vertical surfaces, double termination ribs

shall be in the horizontal direction. All joints shall be protected and made mortar-tight.

During placement and consolidation of concrete, the Contractor shall exercise caution

not to damage the lining and the joints. In removing forms, care shall be taken to protect

the lining from damage. Sharp instruments shall not be used to pry forms from lined

surfaces. After all forms have been removed, nails, form ties and protruding wire or

metal objects shall be cut back from the surface and holes filled with grout and pointed

flush, then weld strips applied. All work including preheating of sheets in cold weather

and the building of all joints shall be done in strict conformance with the specifications,

instructions and recommendations of the lining manufacturer. All pipes, conduits, and

sleeves passing through the lining shall be flashed as shown or as recommended and

demonstrated by the manufacturer. All defective joints, wrinkles and area which do not

bond to concrete shall be repaired by the Contractor to the satisfaction of the


Bonding of the Type II lining to the concrete surfaces shall be accomplished by the

application of the primer specified in this section to the prepared concrete surface

following with the mastic also specified in this section as an intermediate layer.

Application of the bonding material, installation of lining surface preparation and

joining shall be in accordance with the recommendation of the manufacturer.

When external groundwater is present, dewatering procedures must be continued for a

minimum of 24 hours after final installation of mastic.

B. Joints in Lining

Lining at joints shall be free of all mortar and other foreign material and shall be clean

and dry before joints are made. Field joints in the lining shall be made by lapping sheets

not less than 1/2 inch. One 1-inch welding strip is required. The upstream sheet shall

overlap the one downstream. The lap shall be heat-sealed into place prior to welding on

the 1-inch welding strip.

C. Joint Welding

All welding of joints is to be in strict conformance with the specifications and

instructions of the lining manufacturer.

Welding shall fuse both sheets and weld strip together to provide a continuous joint

equal in corrosion resistance and impermeability to the liner plate.

Hot air welding tools shall provide effluent air to the sheets to be joined at a temperature

between 500 degrees F and 600 degrees F. Welding tools shall be held approximately

1/2 inch from and moved back and forth over the junction of the two materials to be

joined. The welding tool shall be moved slowly enough as the weld progresses to cause

a small bead of molten material to be visible along both edges and in front of the weld

strip.

D. Special Requirements

Unless otherwise shown on the plans, the lining shall be returned at least 3 inches at the

surfaces of contact between the concrete structure and items not of concrete (including

manhole frames, gate guides, clay pipe or brick manholes and clay or cast iron pipes).

The same procedure shall be followed at joints where the type of protective lining is

changed or the new work is built to join existing unlined concrete. At each return, the

returned liner shall be sealed to the item in contact with the plastic-lined concrete using

Amer-Plate 19Y adhesive system. If the liner cannot be sealed with this adhesive

because of the joint at the return being too wide or rough or because of safety

regulations, the joint space shall be densely caulked with lead wool or other approved

caulking material to a depth of 2 inches and finished with a minimum of 1 inch of an

approved corrosion resistant material.

E. Lining Patching and Repair

All nail and tie holes and all cut, torn and seriously abraded areas in the lining shall be

patched. Patches made entirely with welding strip shall be fused to the liner over the

entire patch area. Larger patches may consist of smooth liner sheet applied over the

damaged area with adhesive. All edges must be covered with welding strip fused to the

patch and the sound lining adjoining the damaged area.

3.02 TESTING

After the installation is complete, all surfaces covered with lining, including welds, shall

be tested by the Contractor with an approved electrical holiday (Timker and Rasor

Model No. AP-W with power pack) or flow detector with the instruments to be set

between 18,000-22,000 volts. All welds shall be physically tested by nondestructive

probing methods. All patches over holes, or repairs to the liner wherever damage has

occurred, shall be accomplished in accordance with Part 3.01E, Lining, Patching and

Repair.

Each transverse welding strip which extends to a lower edge of the liner will be tested

by the Contractor. The welding strips shall extend 2 inches below the liner to provide a

tab. A 10-pound pull shall be applied to each tab. The force shall be applied normal to

the face of the structure by means of a spring balance. The liner adjoining the welding

strip shall be held against the concrete during application of the force. The 10-pound

pull shall be maintained if a weld failure develops until no further separation occurs.

Defective weld shall be retested after repairs have been made. Tabs shall be trimmed

away neatly by the installer of the liner after the welding strip has passed inspection.

Inspection shall be made within 2 days after joint has been completed in order to prevent

tearing the projecting weld strip and consequent damage to the liner from equipment and

materials used in or taken through the work.

Liner plate locking extensions embedded in concrete shall withstand a test pull of at

least 100 pounds per linear inch applied perpendicular to the concrete surface for a

period of 1 minute, without rupture of the locking extensions or withdrawal from

embedment. This test shall be made at a temperature between 70°F to 80°F.

Lining plate locking extensions embedded in concrete shall withstand a test pull of at

least 20 pounds per linear inch, applied perpendicularly to the concrete surface for a

period of one minute, without rupture of the locking extensions or withdrawal from the

intermediate mastic layer or delamination of the mastic from the concrete substrate. This

test shall be made at a temperature of 70º - 80ºF inclusive and not before mastic has

cured at least 7 days.

The Construction Manager or his representative shall inspect the lining to ensure proper

installation. Any defects shall be repaired by the Contractor.

(ii) (a) Any class of laborers or mechanics which is not listed in the wage determination and which is to be employed under the contract shall be classified in conformance with the wage determination. HUD shall approve an additional classification and wage rate and fringe benefits therefore only when the following criteria have been met.

(1) The work to be performed by the classification requested is not performed by a classification in the wage determination; and

(2) The classification is utilized in the area by the construction industry; and (3) The proposed wage rate, including any bona fide fringe benefits, bears a reasonable relationship to the wage

rates contained in the wage determination. (b) If the Contractor and the laborers and mechanics to be employed in the classification (if known), or their

representatives. and HUD or its designee agree on the classification and wage rate (including the amount designated for fringe benefits where appropriate), a report of the action taken shall be sent by HUD or its designee to the Administrator of the Wage and Hour Division, Employment Standards Administration, U.S. Department of Labor, Washington, D.C. 20210. The Administrator, or an authorized representative, will approve, modify or disapprove every additional classification action within thirty (30) days of receipt and so advise HUD or its designee or will notify HUD or its designee within the thirty (30) day period that additional time is necessary. (Approved by the Office of Management and Budget under OMB control number 1215-0140.)

(c) In the event the Contractor, the laborers or mechanics to be employed in the classification or their representatives, and HUD or its designee do not agree on the proposed classification and wage rate (including the amount designated for fringe benefits, where appropriate), HUD or its designee shall refer the questions, including the views of all interested parties and the recommendation of HUD or its designee, to the Administrator for determination. The Administrator, or an authorized representative, will issue a determination within thirty (30) days of receipt and so advise HUD or its designee or will notify HUD or its designee within the thirty (30) day period that additional time is necessary. (Approved by the Office of Management and Budget under OMB Control Number 1215-0140.)

(d) The wage rate (including fringe benefits where appropriate) determined pursuant to subparagraphs (1)(b) or (c) of this paragraph, shall be paid to all workers performing work in the classification under this Contract from the first (1

st) day on which

work is performed in the classification. (iii) Whenever the minimum wage rate prescribed in the Contract for a class of laborers or mechanics includes a

fringe benefit which is not expressed as an hourly rate, the Contractor shall either pay the benefit as stated in the wage determination or shall pay another bona fide fringe benefit or an hourly cash equivalent thereof.

(iv) If the Contractor does not make payments to a trustee or other third person, the Contractor may consider as part of the wages of any laborer or mechanic the amount of any costs reasonably anticipated in providing bona fide fringe benefits under a plan or program, provided, that the Secretary of Labor has found, upon the written request of the Contractor, that the applicable standards of the Davis-Bacon Act have been met. The Secretary of Labor may require the Contractor to set aside in a separate account assets for the meeting of obligations under the plan or program. (Approved by the Office of Management and Budget under OMB Control Number 1215-0140.)

2. Withholding. HUD or its designee shall upon its own action or upon written request of an authorized representative of the Department of Labor withhold or cause to be withheld from the Contractor under this Contract or any other Federal contract with the Contractor, or any other Federally-assisted contract subject to Davis-Bacon prevailing wage requirements, which is held by the Ccontractor so much of the accrued payments or advances as may be considered necessary to pay laborers and mechanics, including apprentices, trainees and helpers, employed by the Contractor or any subcontractor the full amount of wages required by the Contract. In the event of failure to pay any laborer or mechanic, including any apprentice, trainee or helper, employed or working on the site of the work (or under the United States Housing Act of 1937 or under the Housing Act of 1949 in the construction or development of the project), all or part of the wages required by the Contract HUD or its designee may, after written notice to the Contractor, sponsor, applicant or owner, take such action as may be necessary to cause the suspension of any further payment advance or guarantee of funds until such violations have ceased. HUD or its designee may, after written notice to the Contractor, disburse such amounts withheld for and on account of the Contractor or subcontractor to the respective employees

to whom they are due. The Comptroller General shall make such disbursements in the case of direct Davis-Bacon Act contracts. 3. (I) Payrolls and Basic Records. Payrolls and basic records relating thereto shall be maintained by the

Contractor during the course of the work preserved for a period of three (3) years thereafter for all laborers and mechanics working at the site of the work (or under the United States Housing Act of 1937, or under the Housing Act of 1949, in the construction or development of the project). Such records shall contain the name, address and social security number of each such worker. his or her correct classification, hourly rates of wages paid (including rates of contributions or costs anticipated for bona fide fringe benefits or cash equivalents thereof of the types described in Section I (b)(2)(B) of the Davis-Bacon Act), daily and weekly number of hours worked, deductions made and actual wages paid. Whenever the Secretary of Labor has found under 29 CFR 5.5 (a)(1)(iv) that the wages of any laborer or mechanic include the amount of any costs reasonably anticipated in providing benefits under a plan or program described in Section I (b)(2)(B) of the Davis-Bacon Act, the Contractor shall maintain records which show that the commitment to provide such benefits is enforceable, that the plan or program is financially responsible, that the plan or program has been communicated in writing to the laborers or mechanics affected and records which show the costs anticipated or the actual cost incurred in providing such benefits. Contractors employing apprentices or trainees under approved programs shall maintain written evidence of the registration of apprenticeship programs and certification of trainee programs, the registration of the apprentices and trainees and the ratios and wage rates prescribed in the applicable programs. (Approved by the Office of Management and Budget under OMB Control Numbers 1215-0140 and 1215-0017.)

(ii) (a) The Contractor shall submit weekly for each week in which any Contract work is performed a copy of all payrolls to HUD or its designee if the agency is a party to the Contract but if the agency is not such a party, the Contractor will submit the payrolls to the applicant sponsor, or owner, as the case may be, for transmission to HUD or its designee. The payrolls submitted shall set out accurately and completely all of the information required to be maintained under 29 CFR Part 5.5(a)(3)(i). This information may be submitted in any form desired. Optional Form WH-347 is available for this purpose and may be purchased from the Superintendent of Documents (Federal Stock Number 029-005-WO14-1), U.S. Government Printing Office, Washington, D.C. 20402. The Contractor is responsible for the submission of copies of payrolls by all subcontractors. (Approved by the Office of Management and Budget under OMB Control Number 1215-0149.)

(b) Each payroll submitted shall be accompanied by a "Statement of Compliance," signed by the Contractor or subcontractor or his or her agent who pays or supervises the payment of the persons employed under the Contract and shall certify the following:

(1) That the payroll for the payroll period contains the information required to be maintained under 29 CFR Part 5.5 (a)(3)(i) and that such information is correct and complete;

(2) That each laborer or mechanic (including each helper, apprentice and trainee) employed on the Contract during the payroll period has been paid the full weekly wages earned, without rebate, either directly or indirectly, and that no deductions have been made either directly or indirectly from the full wages earned, other than permissible deductions as set forth in 29 CFR Part 3;

(3) That each laborer or mechanic has been paid not less than the applicable wage rates and fringe benefits or cash equivalents for the classification of work performed, as specified in the applicable wage determination incorporated into the Contract;

(c) The weekly submission of a properly executed certification set forth on the reverse side of Optional Form WH-347 shall satisfy the requirement for submission of the "Statement of Compliance" required by paragraph A.3.(ii)(b) of this section.

(d) The falsification of any of the above certifications may subject the Contractor or any subcontractor to civil or criminal prosecution under Section 1001 of Title 18 and Section 231 of Title 31 of the United States Code.

(iii) The Contractor or any subcontractor shall make the records required under paragraph A.3.(i) of this section available for inspection, copying or transcription by authorized representatives of HUD or its designee or the Department of Labor, and shall permit such representatives to interview employees during working hours on the job. If the Contractor or subcontractor fails to submit the required records or to make them available, HUD or its designee may, after written notice to the Contractor, sponsor, applicant or owner, take such action as may be necessary to cause the suspension of any further payment advance or guarantee of funds. Furthermore, failure to submit the required records upon request or to make such records available may be grounds for debarment action pursuant to 29 CFR Part 5.1 2.

4. (i) Apprentices and Trainees. Apprentices. Apprentices will be permitted to work at less than the predetermined rate for the work they performed when they are employed pursuant to and individually registered in a bona fide apprenticeship program registered with the U.S. Department of Labor, Employment and Training Administration, Bureau of Apprenticeship and Training or with a State Apprenticeship Agency recognized by the Bureau, or if a person is employed in his or her first ninety (90) days of probationary employment as an apprentice in such an apprenticeship program, who is not individually registered in the program, but who has been certified by the Bureau of Apprenticeship and Training or a State Apprenticeship Agency (where appropriate) to be eligible for probationary employment as an apprentice. The allowable ratio of apprentices to journeymen on the job site in any craft classification shall not be greater than the ratio permitted to the Contractor as to the entire work force under the registered program. Any worker listed on a payroll at an apprentice wage rate, who is not registered or otherwise employed as stated above, shall be paid not less than the applicable wage rate on the wage determination for the classification of work actually performed. In addition, any apprentice performing work on the job site in excess of the ratio permitted under the registered program shall be paid not less than the applicable wage rate on the wage determination for the work actually performed. Where the Contractor is performing construction on a project in a locality other than that in which its program is registered, the ratios and wage rates (expressed in percentages of the journeyman's hourly rate) specified in the Contractor's or subcontractor's registered program shall be observed. Every apprentice must be paid at not less than the rate specified in the registered program for the apprentice's level of progress, expressed as a percentage of the journeymen hourly rate specified in the applicable wage determination. Apprentices shall be paid fringe benefits in accordance with the provisions of the apprenticeship program. If the apprenticeship program does not specify fringe benefits, apprentices must be paid the full amount of fringe benefits listed on the wage determination for the applicable classification. If the Administrator determines that a different practice prevails for the applicable apprentice classification, fringes shall be paid in accordance with that determination. In the event the Bureau of Apprenticeship and Training, or a State Apprenticeship Agency recognized by the Bureau, withdraws approval of an apprenticeship program, the Contractor will no longer be permitted to utilize apprentices at less than the applicable predetermined rate for the work performed until an acceptable program is approved.

(ii) Trainees. Except as provided in 29 CFR 5.16, trainees will not be permitted to work at less than the predetermined rate for the work performed unless they are employed pursuant to and individually registered in a program which has

received prior approval, evidenced by formal certification by the U.S. Department of Labor, Employment and Training Administration. The ratio of trainees to journeymen on the job site shall not be greater than permitted under the plan approved by the Employment and Training Administration. Every trainee must be paid at not less than the rate specified in the approved program for the trainee's level of progress, expressed as a percentage of the journeyman hourly rate specified in the applicable wage determination. Trainees shall be paid fringe benefits in accordance with the provisions of the trainee program. If the trainee program does not mention fringe benefits, trainees shall be paid the full amount of fringe benefits listed on the wage determination unless the Administrator of the Wage and Hour Division determines that there is an apprenticeship program associated with the corresponding journeyman wage rate on the wage determination which provides for less than full fringe benefits for apprentices. Any employee listed on the payroll at a trainee rate who is not registered and participating in a training plan approved by the Employment and Training Administration shall be paid not less than the applicable wage rate on the wage determination for the work actually performed. In addition, any trainee performing work on the job site in excess of the ratio permitted under the registered program shall be paid not less than the applicable wage rate on the wage determination for the work actually performed. In the event the Employment and Training Administration withdraws approval of a training program, the Contractor will no longer be permitted to utilize trainees at less than the applicable predetermined rate for the work performed until an acceptable program is approved.

(iii) Equal Employment Opportunity. The utilization of apprentices, trainees and journeymen under this part shall be in conformity with the equal employment opportunity requirements of Executive Order 11246, as amended, and 29 CFR Part 30.

9. Disputes Concerning Labor Standards. Disputes arising out of the labor standards provisions of this Contract shall not be subject to the general disputes clause of this Contract. Such disputes shall be resolved in accordance with the procedures of the Department of Labor set forth in 29 CFR Parts 5, 6 and 7. Disputes within the meaning of this clause include disputes between the Contractor (or any of its subcontractors) and HUD or its designee, the U.S. Department of Labor or the employees or their representatives.

11. Complaints, Proceedings or Testimony by Employees. No laborer or mechanic to whom the wage, salary or other labor standards provisions of this Contract are applicable shall be discharged or in any other manner discriminated against by the Contractor or any subcontractor because such employee has filed any complaint or instituted or caused to be instituted any proceeding or has testified or is about to testify in any proceeding under or relating to the labor standards applicable under this Contract to his employer.

B. Contract Work Hours and Safety Standards Act. As used in this paragraph, the terms "laborers" and "mechanics" include watchmen and guards.
