DETAIL ESTIMATING WRITERS GUIDE FOR CDED CHAPTER B

001 WRITERS GUIDE for CDED MANUAL CHAPTER B DETAIL ESTIMATING

001.1 GENERAL

001.1.1 Introduction

The purpose of this document is to provide insight and guidance to persons involved in writing Contract Design Estimation and Documentation (CDED) Chapter B sections.

CDED Chapter B sections provide designer guidance on how to design, estimate quantities and document tender items related to each applicable Ontario Provincial Standard (OPS) construction specification. The CDED Manual, Chapter B typically forms part of the terms-of-reference for detailed design projects. Design project managers and the project team shall follow the guidance given unless reasons exist to do things in different ways. Designers shall be prepared to explain and justify departures from the guidance provided. The end-product includes a biddable tender package and a constructible design package that is suitable for administration of capital construction projects on the Ministrys Provincial highway network.

The CDED Manual is the guide for designers to complete detailed design for highways. Some Structural and all Electrical engineering functions are not covered by the CDED manual, Chapter B. Guidance in detailed design for those engineering functions may be obtained in the Structural Manual and Electrical Engineering Manual, Volume 3, Electrical CDED and Volume 4, Electrical CDED ATMS (Advanced Traffic Management systems) respectively.

001.1.2 Contract Documentation

The core of tender packages consists of the tender. The tender is supported by engineering standards, including: Ontario Provincial Standard Specifications (OPSSs), Ontario Provincial Standard Drawings (OPSDs) and Ministry of Transportation

Ontario Drawings (MTODs). Standard Special Provisions (SSPs) are used to modify OPSSs, as warranted.

The tender package also includes: Contract Drawings are drawings or plans provided by the owner for the work, as

defined in the MTO General Conditions of Contract (OPSS.PROV 100), GC 1.07. Non-standard special provisions (NSSPs) which supplement and modify the

standards to provide specific information on the Construction Project.

January 2010 Pg. 1 of 16 B001


The MTO General Conditions of Contract (OPSS.PROV 100), GC 2.02, Order of Precedence, provides guidance on the relationship between the different types of documents.

The tender package contains adequate information to estimate the cost of the work for tendering purposes. Supporting information in the design package provides all the details required to construct the work. This includes all dimensioned data, such as detailed cross-sections for example.

When changes are made to engineering standards, the corresponding sections of the CDED Manual, Chapter B and the CA&IT Manual should be updated. Having these documents compatible with one-another will help to ensure that tender packages are properly assembled and construction contracts are properly administered.

001.1.3 Authors and Readers of CDED Chapter B Sections

Authors of CDED Chapter B sections: are typically representatives from engineering functional offices within the

Ministry that are similarly involved with writing and updating design policies and contract documentation, including OPS Specifications.

are assumed to have a good understanding of the technical subject (engineering discipline) that is relevant to the Chapter B section. For multi-disciplinary Chapter B sections, consultation with other functional offices may be necessary. The author and their office colleagues are assumed to have a good understanding of ministry construction practice with respect to the particular subject. Liaison with CMO may be necessary to confirm ministry practice regarding construction administration.



Liaison with regional staff and the appropriate functional committee(s) may be necessary to obtain an adequate understanding of the current practices in all of the ministrys regions.

may not have direct experience in creating contract documents or administering construction contracts and may need some assistance with the documentation functions. Staff of the Quality Standards Section (QSS), DCSO are able to assist with this.

Readers of Chapter B sections: are typically project managers and their project team for a detailed design project.

These persons could be ministry staff or employees of an engineering consulting firm.

will often be relying on the technical content of design reports and will not be in a position to technically review them or accept responsibility for their content.

will often be responsible to assemble a contract package as a deliverable. Such a person may have a reasonable understanding of ministry construction practice and the components of a tender package and a design package.

001.1.4 Writing Chapter B Sections

This writers guide is set in the same format in MS Word as CDED Chapter B sections. This MS Word document may be used as a template to start writing a new CDED Chapter B Section.

Write the CDED section as if you are directly telling the reader how to design, estimate and document the design project to create a tender package. Use standard English with good grammar and complete sentences. Where appropriate, diagrams, figures, tables, numbered lists or bulleted lists may be used. Large tables or figures should be included in an appendix to the Chapter B section. Expand all acronyms at first usage within the section.

Under sub-section 1: GENERAL, provide a general description of the subject being covered. Discuss major principles, constraints or limitations. Describe how other tender item quantities may be influenced by installations under these tender items, as applicable. For these cases provide reference to the appropriate CDED Chapter B sections. For example, many tender items cover installation of appurtenances (i.e. safety hardware, drainage features, illumination, etc.) that will influence grading requirements. Details on the contents of sub-sections 2 through 8 are given below in the corresponding sub-section.

001.1.5 Section, Sub-section Numbering and Headings

The CDED B-section title should match the title of the corresponding OPS construction specification, where practical. The Chapter B section number corresponds to the three-digit OPS construction specification number and the first four digits of the



tender item code (first digit is zero) for related tender items. Where multiple CDED Chapter B sections are applicable to one OPSS, they are further identified as -1, -2, etc.

There are nine mandatory standardized first-level sub-section headings in each Chapter B section. Second-level headings may be used at the authors discretion. Some possible second level headings are provided, but their applicability depends on the subject being covered. Second-level headings are appropriate to subdivide a lengthy sub-section.

001.1.6 Step Process to Write a Draft CDED Chapter B section

A CDED Chapter B Section shall be revised to be compatible with any changes are made to the corresponding OPSS, or SSPs.

This process should be initiated when an OPSS and related documents are being developed by the ministry or by an OPS Specialty Committee. This will allow the CDED Chapter B section to be nearly complete by the time that the OPSS is published. Final edits may be done, based on the published OPSS, when it becomes available. This will help to ensure that OPSS and all related documents may be implemented in CPS per the scheduling requirements set out in the Memorandum Implementation of OPS Specifications in Construction Contracts (dated: August 27, 2007 and signed by G. Todd).

Step 1 Assemble and review all relevant contract documentation. Obtain the existing CDED Chapter B section, as applicable Obtain the applicable published OPS specification (or OPSS under development,

as applicable) and standard drawings. Obtain existing applicable standard special provisions (SSPs). Additional

information may be found in Regional non-standard special provisions (Regional NSSPs).

Confirm that the published specification is compatible with current ministry practices and policies.

Follow the requirements of the document: Scheduling and Tracking Updates of Standard Specifications and the CDED Manual (dated November 30, 2007) See Appendix A.

Establish whether the existing and/or proposed standard tender items are appropriate.

SSP(s) may be required to modify the published OPSS.

Step 2 Gather all pertinent design-related information Obtain and review the content of any design documents that may be a reference

document (i.e. manuals, design memoranda, design bulletins). The Quality Systems Section of the Design and Contract Standards Office can

provide a list of OPSSs and SSPs that have a reference to the subject OPSS.

Step 3 Produce first draft of CDED Chapter B section Refer to this document and existing, recently published CDED Chapter B sections

for guidance and examples.

Step 4 Review content with appropriate functional committee(s) and/or regional staff Review the contract documentation and draft CDED section to ensure that it is

compatible with current practice. Obtain any feedback from the functional committee or regional staff. Make any

appropriate changes to the draft. Any construction administration issues should be reviewed with CMO.



Step 5 Review content with Quality Systems Section (QSS), DCSO. Via E-mail, send electronic copies of the draft CDED Chapter B section, along

with the applicable OPS specification, any draft SSP(s) and applicable standard drawings.

In the covering E-mail, describe all the documentation for implementation, along with any proposed tender item revisions. Also note any corresponding documentation that is currently active in CPS which will be superceded.

Address comments received back from QSS

Step 6 Review with the Design Implementation (DI) Committee. DI Committee meeting agendas and schedules are arranged through QSS. The draft CDED Chapter B section, and all related documents (OPSS, OPSDs,

SSPs, as applicable) shall be distributed to DI Committee a minimum of two weeks in advance of the next scheduled meeting.

Functional office representation at the DI Committee meeting is essential. Address comments received back from the DI Committee. Finalize Chapter B section.

Step 7 Implement the CDED Chapter B section and applicable OPSS, SSP and OPSDs intoContract Preparation System (CPS). Submit all finalized documentation to QSS with a covering E-mail in the same

manner as Step 5, above. As applicable, co-ordinate this activity with an update to the Construction

Administration and Inspection Task (CA&IT) Manual that is administered by CMO.

001.1.7 Use of Words

shall: indicates a mandatory obligation and is widely used in standard specifications and similarly used in CDED Chapter B Sections.

should: is used to describe use of a recommended practice.

may: indicates that there is a choice. May is typically to allow an exception to a rule, provided that certain circumstances apply

001.2 REFERENCES

List all applicable Ministry design manuals, directives, memoranda or bulletins in this section. Construction standards documentation is listed under appropriate headings below. Do not repeat references of documentation that are provided in the referenced OPSS. Referenced documents should be discussed within the body of the CDED



Chapter B section so that designers are directed appropriately to these specific documents.

All referenced documents should be readily available to the designer. Include the source of the document, as applicable. The source could be a library, publisher or web-site. Such reference documents would typically be listed in the terms-of-reference for a consultant assignment of a detailed design project.

List proprietary documentation, such as design guides or installation guides, if applicable.

A brief description of the type of information to be obtained from reference documents may be provided, as it pertains to the applicable tender item(s). Any design document referred to within the Chapter B section should be listed in the REFERENCES sub-section.

List project-specific design reports that are typically provided for the applicable engineering function. As a CDED Chapter B section is typically used by project Managers and the project team, it is not necessary to include reference documents of a highly technical nature that would be used only by practitioners of specific engineering functions. Designers would typically rely upon and follow the recommendations within a design report from such practitioners and would not need to address or verify the details provided by those functions.

001.2.1 Reference Documents (as applicable to this guide)

OPSS.PROV 100; MTO General Conditions of Contract Recently implemented CDED Chapter B Sections CDED, Chapter F; Contract Documents Highway Design Bulletin 2008-003; Management of New: Non-Standard Tender

Items, Non-Standard Special Provisions and Modified Standard Special Provisions.

Structural Manual Electrical Engineering Manual Construction Administration and Inspection Task Manual

001.3 TENDER ITEMS

List tender item names. These should exactly match the tender item names given in the OPS specification or SSPs (if applicable) and in CPS.

Applicable tender items are identified in CPS by the 2nd, 3rd and 4th digits of the tender item code which correspond to the three-digit OPSS construction specification number and the three-digit number for the CDED Chapter B Section. Codes are not required to be included.



001.4 SPECIFICATIONS

Provide a general reference about where applicable Ontario Provincial Standard Specifications (OPSS) are located.

The subject OPSS is identified, as applicable. The OPSS number may represent either an OPSS.common or OPSS.PROV (Provincial) Specification, as applicable. However, if an OPSS.MUNI (Municipal) is required, it must be specifically identified.

001.5 SPECIAL PROVISIONS

Provide a general reference about where applicable standard special provisions (SSPs) are located. Specific references to SSPs should not be given. Designers will rely on SSP warrants to ensure that appropriate SSPs are included in the contract documents.

Use of fill-in SSPs may be appropriate for cases where similar project-specific details must be included repetitively in many contracts. The Notes to Designer appendix to an SSP should only be used to include information to assist the designer to complete fill-in SSPs. All other SSP-related information should be contained in the corresponding CDED Chapter B section.

The warrant for use of each SSP is provided at the end of the SSP.

001.5.1 Non-Standard Special Provisions (NSSPs)

Discuss possible needs for NSSPs, if applicable, under Section 9: DOCUMENTATION, below.

Regional Offices have Regional NSSPs that they typically use to apply specific requirements to particular situations. Regional NSSPs may be downloaded from CPS.

001.6 STANDARD DRAWINGS

Provide a general reference about where applicable standard drawings are located. Ontario Provincial Standard Drawings (OPSDs), MTO Drawings (MTODs) and Structural Standard Drawings (SSDs) may be applicable. Reference would typically be made to a division or hundred series of drawings, not the individual drawing numbers. For example: 200 Series drawings are for General Grading features. The individual OPSDs or MTODs may change on a frequent basis which, if included, would require updating of the corresponding CDED Chapter B section each time such a change was made.



001.7 DESIGN

Discuss circumstances where use of specific tender items is recommended. Information may be provided on the relationship and applicability of the various design manuals to the particular tender items. Any design manuals shall be listed in sub-section 2: REFERENCES, above. For cases where design manuals do not exist, a complete discussion of design requirements is appropriate in this sub-section.

Providing a brief summary of design requirements is not recommended because it may be problematic, as readers may be led to believe that all design requirement details have been met.

001.7.1 Information to be Provided to Bidders

Bidders will need specific information in order to bid on the tendered work. Providing such detailed information will allow bidders to provide a well-informed and competitive bid. This will help to reduce risks and extra costs associated with uncertainty. Such information could include but is not limited to: Geotechnical borehole data Survey data Existing condition data

001.8 COMPUTATION

Discuss each tender item or group of similar tender items in a separate paragraph.

Indicate whether each tender item is Plan Quantity Payment (PQP) item. This information is available in CPS for existing tender items but will need to be determined for all new tender items. The level of checking or verification should be provided for PQP tender items.

There is a unique unit-of-measure (UOM) to express the quantity for each tender item, as provided in CPS. Discuss the UOM for each tender item and specifically how the quantity is measured. For example, linear measure in metres, m, could be either horizontal or following a slope. Describe from where the quantity measurement may be obtained. For example: quantities may be measured from field measurement, design cross-sections or contract drawings, etc.

Detailed discussion may be provided on how to measure tender quantities in difficult or unusual project-specific situations, where appropriate. The complimentary summary sheet form (PH-CC-44) should be identified for use for computation of applicable tender item quantities.



Some tender items have UOMs of LS/M, LS/M2, LS/M3 and LS/T. These are not PQP items and are mostly structural oriented. Quantities are provided for estimating purposes only. They are similar to lump-sum tender items but allow for tracking of unit prices on a length, area, volume or weight basis. In the tender document, the quantities for these items appear as 100% and the measured quantities do not appear.

Discuss how work done under these tender items may influence requirements for other tender items or their quantities. It may be necessary to discuss how to avoid double payment of the same feature over multiple tender items, where applicable. An example of where double payment could occur would be where the neat lines of different excavations overlap, causing double payment for this excavation.

001.9 DOCUMENTATION

This sub-section provides guidance on how to document tender item(s) with respect to contract drawings, quantity sheets and NSSPs. Project-specific details are provided in these documents. Improving consistency in documentation across the province will improve quality and efficiency.

OPSSs often contain wording, such as: ., as specified in the Contract Documents. This guides readers to seek out more project-specific information elsewhere in the contract. Such information may reside in other specifications, SSPs, quantity sheets or drawings (OPSDs or MTODs). However, for some cases, such information may be required within the non-standard documentation to address project-specific circumstances. For each such notation in the OPSS, the writer of the CDED Chapter B section should verify that the required information is either contained in the accompanying standard documents or will be accounted for in the project-specific non-standard documentation. Where non-standard documentation is needed, the CDED Chapter B section must provide guidance to the designer as to how and where in the tender package the details are to be provided. This type of information is often detailed in Appendix A of OPSSs. Appendix A is not used by the Ministry, but it provides useful information that is typically provided in the CDED Chapter B section.

Information contained in standard specifications or other contract documentation should not be repeated.

001.9.1 Contract Drawings

Contract drawings include drawings or plans, profiles, typical cross-sections and non-standard details and may include other reports, lists or schedules. These may include standard or modified OPSDs or MTODs. Explain how to show the information on these drawings, as applicable. Standard symbology is provided in the 100 series of both OPSDs and MTODs.



Provide descriptions of any other information that shall be provided on the contract drawings to support these tender items. For example: geotechnical borehole data.

Quantity sheets are considered to be contract drawings. Sample quantity sheets may be obtained from Chapter F. Instructions on which quantity sheet format to use and how to complete filling it out, for each applicable tender item, is covered in sub-section 9: DOCUMENTATION.

001.9.2 Quantity Sheets (Q-sheets)

Q-sheets are usually provided in 11X17 format. Information on Q-sheets is contained in CDED Chapter F. As applicable to the tender item, provide a line entry in the Q-sheet for each installation or segment of product to be supplied, installed or constructed. As applicable, locate the installation by including start and end locations (chainages) of each installation and indicate left or right of centreline. Separate tender items should not be combined on one line of the Q-sheet.

Indicate whether additional information in addition to chainage is required, for example: offset, left or right. In complex projects, staging considerations should be accounted for such that quantities applicable to each stage are provided. The required accuracy of such dimensions should be included in the CDED Chapter B section, where appropriate.

For variation tender items, list each possible variation with a brief explanation of its application. Each variation of the tender item shall be entered in a separate column heading in the Q-sheet. The space available for headings is 92 characters (4 lines of up to 23 characters each). Quantities for each installation shall be entered in the Q-sheet in the appropriate box where the line for that installation meets the column applicable to the tender item variation. An appropriate title shall be provided for each column in the quantity sheet.

Tender item column types Breakdown Normal Variation Special

Column types of tender items are documented in Contract Preparation System (CPS), under CPS Help. This type influences how these items are documented in quantity sheets (Q-sheets). The type of each tender item listed in CPS is listed under Items Master.



001.9.3 Non-Standard Special Provisions (NSSPs)

Discuss how project-specific information is documented in NSSPs, modified SSPs and fill-in SSPs.

Improperly drafted NSSPs are a major source of contractual problems that lead to engineering claims. Use of NSSPs should be minimized, where possible. The use of existing contract documentation, including NSSPs that have been successfully used before, is usually preferable to drafting new NSSPs.

References on how to write NSSPs are included in the SP writers guide. See CDED Chapter E for detailed information on how to write SSPs and NSSPs.

The requirements of Highway Design Bulletin 2008-003, Management of New: Non-Standard Tender Items, Non-Standard Special Provisions and Modified Standard Special Provisions, shall be complied with for the NSSP and non-standard tender item review process.

001.9.4 Documentation Accuracy

Indicate the accuracy (rounding) for the UOM of the tender quantity.



Appendix A

Scheduling and Tracking Updates of Standard Specifications and the Contract Design Estimating and Documentation Manual

November 30, 2007

Objectives:

1. To update OPS specifications in the Ontario Ministry of Transportations (MTO) Contract Preparation System (CPS) in order to streamline contract documents by:

a) Incorporating special provisions into an OPS specification for submission to OPS for publication, or

b) Adopting the latest published version of an OPS specification when it suits MTOs needs. The latest published version of an OPS specification is considered to suit MTOs needs when: i) Its technical content fulfills MTO requirements and ii) Its administrative, quality control and quality assurance, and payment content

conform to MTO policy and practice, OR a standard special provision with a total length of not more than two pages,

excluding any text that is directly related to any fill-in portion of the special provision, can be used to make the latest published version of the OPS specification conform to i) and ii) above.

2. To assist designers in their roles by reviewing and updating all chapters in the Contract Design Estimating and Documentation (CDED) Manual.

OPS Review Process Overview dated September 26, 2007

OPS Review Process Protocols dated November 26, 2007

Background:

The updating of the Contract, Design, Estimating and Documentation Manual began in December 2006. In early 2007, the effort to reduce special provisions by including themin specifications extended to all functional areas when OPS officially introduced OPSS.PROV



specifications. The update of specifications and the CDED Manual need to be planned together so that the CDED Manual reflects the specifications that will be used in contracts.

A worksheet for scheduling and tracking purposes has been provided by the Quality Systems Section, DCSO, to each custodial office/section responsible for individual OPS construction specifications and their associated CDED chapters and individual OPS material specifications. In most cases, the same office/section is custodian of the OPS construction specification and the CDED chapters. The exceptions are noted in the tracking sheets for the Concrete Section, MERO, and the Design Innovations Section, DCSO. Similarly, the custodial office/section of an OPS construction specification may not be the same custodian of the corresponding OPS material specification. Collaboration is necessary between the custodial offices/sections to coordinate and facilitate the updating of these specifications and chapters. Unless otherwise agreed between the parties, the custodian of the construction specification shall coordinate the scheduling of updates of the associated material specifications and CDED chapters.

The Updating Process:

1. Identifying Specifications for Updating

The custodial office/section shall plan to update an OPS specification in CPS (i.e., the implemented specification) when it is:

a) Modified by one or more standard special provisions that i. are always included with the tender item or the engineering material covered by the

special provision, ii. Exceed a total length of two pages, excluding any text that is directly related to any

fill-in portions of the special provision, and iii. Where at least one of the special provisions has been implemented for a minimum

of two construction seasons, or

b) More than 5 years old,

2. Updating the Implemented Version vs. the Latest Published Version

If a specification requires updating and the implemented version is older than the latest published version, the specification developer in the custodial office shall determine which version will be updated.

In most cases, the latest published version of the OPS specification shall be used since the references in it will more up-to-date and some of MTOs special provisions may have been included in it by an OPS Specialty Committee. Also, the style and format of the specification is likely to be more inline with current OPS practice.

The implemented version of the OPS specification may be used when:



a) The latest published version of the OPS specification has clearly been written for municipal purposes and using the latest published version would require more rewriting than using the implemented version. Depending on the age of the specifications, the WORD documents for both versions are available from the OPS Unit, DCSO for comparison using the Tools- Compare and Merge Documents function, or

b) Agreement from the Head, Quality Systems Section, DCSO, has been obtained.

The developer shall ensure that all references in the specification are updated to the current version of the referenced documents and that the style and format conforms to current OPS practices. OPS specification templates and guidance in OPS style and format are available from the OPS Unit, DCSO.

3. Scheduling the Updates

a) The goal of the updating process is for each custodial office/section to update an annual average of one OPS construction specification, and its associated CDED chapters, or an OPS material specification, every two months beginning in January 2008, until all specifications have been updated. When prioritizing its work of updating OPS specifications for the tracking sheet, the custodial office/section should take into account the age of the specification, the number and complexity of the standard special provisions written against it, and the priority identified in the worksheet for the associated CDED chapters.

For each specification that will be updated, the developer in the custodial office/section shall enter dates in the Target OPS Publication Date of Updated Spec and the Date for Submission of Updated OPSS to DCSO columns of the tracking sheet.

In order to be published by OPS in April, the submission of the updated OPSS to DCSO must be made no later than October 31 of the previous year. In order to be published by OPS in November, the submission must be made no later than May 31 of the same year. Submissions should be scheduled throughout the year(s) to level the workload.

b) The developer in the custodial office/section shall enter dates in the Final Draft

Submission Date column of the tracking sheet for all CDED chapters associated with the specifications.

When specifications are updated, the final draft submission date of the CDED chapters is one month after the targeted OPS publication date (i.e., either May 31 for April publications or December 31 for November publications).

When the specifications do not require updating, but the chapters of the CDED manual require updating, the final draft submission date of the CDED chapters shall be as indicated in the tracking sheet or May 31, 2008, whichever is earlier.



c) In the comments column of the tracking sheet, the developer in the custodial office/section shall identify the OPS material specifications that will be updated for publication at the same time as the OPS construction specification or note the reason why the material specification update will not take place.

As in the case of the OPS construction specifications, the developer shall determine which version to the OPS material specification is to be used. The OPS review process encourages the review and publication of construction and associated material specifications simultaneously. If the latest published version of an OPS construction specification is being used for the updating process, the latest published version of the OPS material specification should also be used.

4. Updating OPS Specifications and the CDED Chapters

Developers are to proceed with the updating of OPS specifications and the CDED chapters as detailed in the tracking sheet. As the OPS specifications are completed, they are to be submitted to the Head, Quality Systems Section, DCSO, as outlined in the OPS Review Process Protocols document.

Updated CDED chapters are to be submitted to the Head, Quality Systems Section, DCSO, as outlined above.


DETAIL ESTIMATING CLEARING

May 2013 Page 1 of 11 B201-1

B201-1 - CLEARING - OPSS 201

201-1.1 GENERAL

The removal of vegetation, usually, is the first operation performed in the

construction of a highway and comes in 2 forms; clearing and close cut clearing.

Clearing consists of the cutting of trees, brush and undergrowth at or below one-half

metre (0.5 m) above the ground, and includes the removal and disposal of windfalls,

felled timber, branches and other litter.

Close cut clearing is the cutting of trees at ground level (i.e. leaving no stump) and is

typically employed in areas where there will be no following grubbing operation.

Where close cut clearing is substituted for clearing (as discussed in subsection

B201-1.1.5) grubbing may be required as determined in CDED B201-3.

Additionally, close cut clearing may be followed by stump removal by mechanical

cutter as specified in CDED B 201-6.

Close Cut Clearing

201-1.4 SPECIFICATION

The requirements for clearing and close cut clearing are contained in OPSS 201.

201-1.5 SPECIAL PROVISIONS

Refer to chapter `E' of this Manual to review applicable standard special provisions.


May 2013 Page 2 of 11 B201-1

Fill-in special provisions are to be included in the contract documents according to

their warrants for the following:

i) Salvaging of trees for property sellers

ii) Disposition of marketable timber from Crown Lands.

201-1.6 STANDARD DRAWINGS - None

201-1.7 DESIGN

201-1.7.1 Environmental Considerations

The value of vegetation is considered high enough to warrant saving the maximum

number of trees possible, rather than follow the practice of completely removing all

growth. In addition, other significant vegetative communities may be identified for

protection. The Ministry would prefer to maintain a sizable specimen tree or

established woodlot than replant with nursery stock. Also, vegetation retained on the

right-of-way has value in minimizing construction impacts and in blending the

reconstructed right-of-way with the adjacent landscape.

Wholesale clearing is to be discouraged, and every effort made to preserve as many

trees as possible, taking into account the cost involved and providing that they do not

constitute a safety hazard and that their condition warrants their retention.

A special effort should be made to save trees adjacent to private property, as they

serve to screen the property from road traffic.

These environmental concerns should be discussed with the Ministry's Environmental

Section.

201-1.7.2 Limits of Clearing

The limits of clearing are established on a project specific basis, with the aim of

providing a roadside landscape which will allow an economical maintenance

program. Clearing should be limited to those areas of actual roadway construction

and where the retention of existing natural growth is deemed undesirable.

Removal of all growth to the right-of-way limits is required only where winter

maintenance (snow storage) or the need for greater exposure to winter sunlight justify

such extra width.


May 2013 Page 3 of 11 B201-1

The designer should discuss the limits of clearing for each project with:

i) Principle Landscape Architect, Design and Contract Standards Office

ii) Regional Environmental Section

iii) Regional Operations Office

iv) Regional Geotechnical Office

201-1.7.3 Advance Clearing

Clearing may be scheduled ahead of the grading contract for the following reasons:

a) To facilitate utility relocation, where only a small portion of the overall clearing

needs to be done to accommodate the work, with the remainder of the clearing left

as part of the grading contract.

b) To provide winter work in areas of high unemployment.

c) Where the area to be cleared is small.

d) To avoid migratory bird nesting timing restrictions where trees need to be cleared

to accommodate the work before the end of the bird nesting timing window.

Advance clearing may be carried out by:

a) The contractor - as a separate contract by tender

b) Operational Services - if available for such work

c) A utility company - for a utility relocation

201-1.7.4 Clearing - Under Grading Contract

Where clearing is part of the main grading contract, and there is insufficient lead time

to relocate utilities in advance of construction possibly affecting the contractor's

schedule of operations, clearing should be done by the Contractor as one of his first

operations and a non-standard special provision is to be included in the contract to

advise the Contractor of the staging requirements.

Clearing of a minor nature may be done by Operational Services (check with the

Regional Head of Operational Services regarding manpower needs and availability)

and the work paid for out of Services (Sundry) funds (see Chapter 'D').

201-1.7.5 Clearing for Utility Relocation

Where clearing is done by a utility company to install or relocate a utility and the

clearing is a Ministry requirement for other construction or for safety reasons, then the

total cost of the clearing will be borne by the Ministry.


May 2013 Page 4 of 11 B201-1

Where the Ministry requests the relocation of a utility to an area beyond the limits of

clearing proposed under the contract, then the utility company shall pay half the cost

of labour for such additional clearing.

Where the utility company installs a new plant or relocates an existing plant within

the Ministry right-of-way and no clearing or grading is scheduled in that area, then the

utility company shall pay the total cost of labour for clearing.

201-1.7.6 Clearing on Crown and Private Lands

a) Crown Lands

All timber cut on a right-of-way through Crown lands becomes the property of the

Ministry who will, in due course, be invoiced by the Ministry of Natural

Resources (MNR) for merchantable wood.

Regional Planning and Design are required to notify the MNR of the proposed

clearing or close cut clearing at least two months prior to the scheduled design

completion date to allow sufficient time to organize a timber cruise. When

notifying MNR, the following information should be forwarded:

i) Commencement date of clearing operation

ii) Whether clearing is to be done by contract or by Operational Services

iii) Commencement date of construction operations

iv) Plan of construction area

The value of the timber will have been determined previously by the MNR from a

timber cruise of the area. Following receipt of an invoice from the MNR, the

Ministry will transfer the ownership of the timber to the Contractor by including

the applicable standard special provision.

b) Timber Licence

The Regional Planning and Design Section is to enquire of the MNR whether

timber rights (e.g. timber berth, registered mining claims, etc.) exist on Crown

lands scheduled for clearing. This information is passed to the Contractor by

means of a standard special provision.

c) Timber Salvage on Private Lands

All timber cut from privately owned lands purchased for right-of-way purposes

becomes the property of the Contractor, unless property purchase agreements

specify otherwise.


May 2013 Page 5 of 11 B201-1

The Regional Design Office must check with the Property Section for timber

salvage information and provide details of same in the contract drawings (see

Subsection 201-1.9 Documentation) and in the contract documents (see

Subsection 201-1.5 Special Provisions).

201-1.7.7 Selective Clearing

Selective clearing is normally carried out after the general contract using Operational

Services, with funds established under "Services (Sundry)" (see Chapter 'D').

Areas for selective clearing are detailed on the construction drawings outside (and

usually adjacent to) the limits of "contract" clearing. These areas are normally

protected by a barrier and denoted as "Areas (or trees) to be retained".

As there are no clearing quantities to be computed for this operation, the work of the

designer is limited to:

a) Liaison with:

i) Principle Landscape Architect, Design and Contract Standards Office

ii) Regional Environmental Section

iii) Regional Operations Office

iv) Utility Co-ordinator

in order to determine the need for tree retention areas and selective clearing;

b) Presenting tree retention areas on construction drawings, with suitable notes, and

distributing copies to those concerned, for comments;

c) Providing the appropriate OPSS 801 for Tree Protection;

d) If needed, generating a tender item "Barrier for Tree Protection" and computing

quantities.

201-1.7.8 Areas of Clearing

Areas which are to be included in the clearing item are as follows:

a) Areas within the right-of-way required for construction, including corners of

intersections where growth may obstruct visibility.

b) Curves where visibility is a problem.

c) Areas recommended for clearing in the Landscape Planning Report.

d) Areas required to construct detours.

e) Areas required to construct stream diversions sideroads, entrances, etc.

f) Areas required to construct ditches within the right-of-way and on areas of limited

interest.


May 2013 Page 6 of 11 B201-1

g) Areas required to accommodate utility relocation within the right-of-way or on

areas of limited interest.

h) Areas with fruit trees on MTO right-of-way in Southern Ontario.

i) Areas within the roadside clear zone. (See the Roadside Safety Manual)

j) Areas for the disposal of surplus materials within MTO right-of-way.

k) Embankments up to and including 1.2 m in height.

Areas cleared, but not included in this item are:

a) Borrow pits.

b) Access roads.

c) Haul roads.

Areas or work covered by other tender items where clearing is paid for as part of the

work of that tender item, such as fencing in wooded areas not designated for clearing.

When the clearing item is small and there is a close cut clearing item in the contract, it

may be more practical to indicate close cut clearing only, and to include grubbing

where required. When both clearing and close cut clearing are large, the clearing item

could be eliminated, but only where experience has shown that separate items would

not result in cost savings.

201-1.7.9 Areas of Close Cut Clearing

Close cut clearing will be prescribed for areas where grubbing is considered

unnecessary or undesirable, such as those:

a) Under embankments higher than 1.2 metres.

b) Where grubbing operations could damage fences, building foundations or

underground utilities (not requiring relocation);

c) Where a matted surface (roots, etc.) provides slope stability;

d) In swamps, where grubbing could rupture the matted surface;

e) Where roots left in place would not interfere with construction or maintenance

operations.

May 2013 Page 8 of 11 B201-1

201-1.8 COMPUTATION

These are Plan Quantity Payment items.

201-1.8.1 Source of Information

The main sources of information for the computation of the tender item "Clearing"

and Close Cut Clearing are the field survey notebooks (see Fig. B201-1-1) and

available plans (B Plans; ETR Books; Photogrammetry Contour Plans).

201-1.8.2 Clearing by Area

The unit of measurement for clearing by area is the hectare (ha).

Clearing by area may comprise areas of solid bush, trees in clumps and rows, or

individual trees, all of which are computed in square metres.

Clearing quantities are computed from details recorded in the field survey notebooks,

or, if not available, by scaling available plans in square metres.


May 2013 Page 9 of 11 B201-1


May 2013 Page 10 of 11 B201-1

201-1.8.3 Clearing of Trees

On suitable projects where the number of trees to be cleared is minimal and there is

no other clearing by area (hectare), the clearing calculation may be based on the total

number of trees greater than 100 mm diameter to be removed, under the unit "each":

The diameter of each tree is determined by measuring its girth at a height of

1.3 metres and recording its diameter; the information being found in the field survey

notebooks.

Those trees which are to remain within the construction area should be suitably

marked by the contractor or by Operational Services.

Do not refer to this operation as "Selective Clearing (see Section 201-1.7.7).

201-1.9 DOCUMENTATION

201-1.9.1 Contract Drawings

Where clearing areas are extensive, they are shown on the removal drawings.

However, where clearing is minor, they may be placed on construction drawings,

providing they do not obstruct the construction details.

Areas identified where timber is to be cut and remain on the property of the property

seller shall be shown on the Removal drawings.

If specific trees are to be retained in an area of clearing, the areas should be shown on

the Removal Drawings, with the note - "....... to be retained". The outline of the treed

area or individual trees to be retained should be shown also on the construction plans

in full intensity.

Prints should be sent to the Principle Landscape Architect for identification of

clearing and subsequent refurbishment, the Regional Environmental Unit for review

by the environmental planner, and the utility co-ordinator to identify clearing and

trees to be saved during construction and utility relocation.

201-1.9.2 Contract Documents

Areas to be cleared are to be entered onto the Quantities - Miscellaneous 1 sheet in

square metres by station location. The position information must clearly indicate the

extent, by centre-line offset, of each individual area to be cleared since this

information will be used for layout & verification purposes during construction.

Quantities, in hectares, are automatically calculated and then totalled at the bottom of

the column.


May 2013 Page 11 of 11 B201-1

Diagrams may be drawn on the Removals sheet to indicate partial clearing in solid

bush areas. Where entire bush areas are to be cleared, diagrams are not necessary as

this type of situation can be described adequately by chainage and offset.

Quantity sheets produced which precludes sketching, may have 350 meter quantity

summaries as long as removal drawings and separate quantity calculations are

provided.

Where rows of trees to be removed are denoted by a single chainage, offsets to both

the beginning and end of the row are required (e.g. Sta. 16 + 473 - 4.1 m Lt. to 25.6 m

Lt.).

It is important that quantities shown on the Quantity sheet have a degree of accuracy

sufficient to be used in the contract as the final payment quantities.

Clumps of single trees are documented by combined spread and area rather than as

single trees.

201-1.9.3 Documentation Accuracy

Chainage Stations: One-tenth of a metre (0.1m)

Chainage offsets: One-tenth of a metre (0.1m)

Areas in square metres: One square metre (1.0 m)

Areas in hectares: One hundredth of a hectare (0.01 ha)

In calculating areas, work to one extra place of decimals and record to the accuracy

shown above.

DETAIL ESTIMATING GRUBBING

May 2013 Page 1 of 3 B201-3

B201-3 - GRUBBING - OPSS 201

201-3.1 GENERAL

Grubbing consists of the removal and disposal of all stumps, roots, embedded logs,

debris and second growth, with the operation usually being performed immediately

following, and as part of, the same contract as clearing or close cut clearing.

Where the right-of-way, or a portion thereof, has been previously cleared or close cut

cleared (under a separate contract, or by Operational Services), the Contractor will,

under the item "Grubbing", clear, remove and dispose of all second growth, brush and

debris from those areas designated for grubbing.

When grubbing requirements are minor, the work may be done by Operational

Services, with funds provided from 'Services (Sundry)' - (see Chapter 'D').

Surface boulders lying within areas designated for grubbing are removed as part of the

work of grubbing, except those one cubic metre (1.0 m) or larger in volume which

are removed under the item "Rock Excavation (Grading)". For treatment of boulders

see section CDED B201-4.

201-3.7.1 Limits of Grubbing

Fig. B201-2-1 in CDED B201-1 shows in principle the application of grubbing.

The designer should discuss the limits of grubbing for each project with:

The Regional Maintenance Office

The Regional Construction Office

The Utility Co-Ordinator

The Regional Environmental Section

201-3.7.2 Grubbing and Advance Grubbing for Utility Relocation and Fencing

Grubbing operations, including advance grubbing, for utility relocations and fencing

are governed by the same principles outlined in CDED B201-1.

201-3.7.3 Areas of Grubbing

Areas to be grubbed are:

a) Excavation areas (except swamp excavation);

b) Under low embankments - up to and including 1.2 metres in height;

c) Offtake ditches and watercourse corrections.

Where swamp excavation is required, embedded low stumps, etc. will be removed as

part of swamp excavation (see CDED B206-1).

201-3.7.4 Disposal of Debris

Debris from grubbing operations may be disposed of both on and off the right-of-way.

In bush areas, debris such as stumps, roots, earth, usually is pushed onto adjacent

private or Crown lands under agreement with the owner or Ministry of Natural

Resources respectively, and with the approval of the Ministry of the Environment; all

arrangements for disposal being the responsibility of the Contractor. Alternatively,

debris may be pushed to the back of the right-of-way and, in suitable areas,


May 2013 Page 3 of 3 B201-3

incorporated into the flattening of sideslopes, but in no case will it be disposed of

within embankments.

Surface litter and second-growth material may be burned on the right-of-way, under

those conditions stated in CDED B201-1.

In rare cases, debris may require hauling off the right-of-way, to disposal sites

arranged for by the Contractor.

201-3.8 COMPUTATION

These are Plan Quantity Payment items.

Computation procedures for grubbing are the same as those for clearing (see CDED

B201-1).


Documentation procedures for grubbing are the same as those for clearing (see CDED

DETAIL ESTIMATING REMOVAL OF BOULDERS

May 2013 Page 1 of 4 B201-4

B201-4 - REMOVAL OF BOULDERS - OPSS 201

201-4.1 GENERAL

The removal of boulders includes the disposal of both surface and piled boulders.

Surface boulders are defined as boulders or rock fragments that measure 200 mm or

greater in any one dimension, above original ground, and can be removed without

excavation.

Piled boulders are defined as any cobbles, boulders, or rock fragments that have been

placed in fencerows or piles.

Boulders or rock fragments one cubic metre (1.0 m) or larger are not part of this

tender item, but are removed under the item "Rock Excavation (Grading)", or, if there

is no such item, as a Change in the Work.

201-4.2 REFERENCES - None


Removal of Surface Boulders

Removal of Piled Boulders


The requirements for the removal of surface and piled boulders are contained in

OPSS 201.





May 2013 Page 2 of 4 B201-4

201-4.7 DESIGN

201-4.7.1 Removal of Surface Boulders

Surface boulders are designated for removal only where they would interfere with

construction or the intended level of maintenance, or where they could become a

traffic hazard. Surface boulders in areas of close cut clearing do not require removal,

unless they interfere with construction.

Where surface boulders occur in fill sections exceeding 1.0 m in height then the

boulders could remain in place.

This item is used when surface boulders to be removed are located beyond areas to be

grubbed.

Surface boulders within grubbing areas are removed as part of grubbing operations

and paid for under the item "Grubbing". No designation or quantity for surface

boulders is indicated on the contract drawings or quantity sheets, in this instance.

Where a surface boulder area lies partly within an area to be grubbed, only that

portion outside the grubbed area is calculated as removal of surface boulders; the

remainder will be removed under the grubbing operation, as described above.

201-4.7.2 Removal of Piled Boulders

Piled boulders are removed only where they interfere with construction; fence

erection; the intended level of maintenance, or would create a hazard to traffic.

Piled boulders (total quantity greater than 100 m), both within and beyond grubbing

areas, are included in the tender item "Removal of Piled Boulders", regardless of

whether the work is done before or during the grubbing operation. (For a total

quantity smaller than 100 m, see subsection 201-4.8.3).

Boulders in piles or fencerows within areas of surface boulder removal are also

removed as part of the item "Removal of Piled Boulders".

No deduction of areas covered by boulders in piles and fencerows are made from any

areas designated for grubbing or removal of surface boulders.

201-4.8 COMPUTATION

When measured, these are Plan Quantity Payment items.


May 2013 Page 3 of 4 B201-4

Lump sum payment may be used for these items when locations are well defined the

quantity is small and it is unlikely that the quantity will vary.


The main sources of information for the computation of the tender item "Removal of

Surface Boulders" are the field survey notebooks and the Geotechnical Report.

The main sources of information for the computation of the tender item "Removal of

Piled Boulders" are the field survey notebooks and ETR (Engineering and Title

Records) Plans (or contour plans).

201-4.8.2 Methods of Calculation

The basic unit of measurement for the removal of surface boulders is the hectare (ha).

The areas of surface boulders to be removed under this tender item are calculated

initially from the field survey notebooks in square metres (m2), summarized on the

Quantity Sheets and converted to hectares.

The basic unit of measurement for the removal of piled boulders is the cubic metre

(m).

201-4.8.3 Small Quantities

Small quantities of surface boulders (up to 0.20 ha) and/or piled boulders (100 m or

less), beyond grubbing areas requiring removal may be included as part of other work

such as "Earth Excavation Grading". A special provision is required to include these

removals with the other work, and the extent of piled boulder removals must be

shown on the contract drawings.

Small quantities within grubbing areas, if not designated on the contract drawings for

removal under a separate tender item, are removed as part of the grubbing operation,

as specified in OPSS 201; a special provision is not required.


201-4.9.1 Surface Boulders

Boulder-strewn areas do not normally require demarcation on contact drawings unless

the area is very irregular and difficult to describe. Areas requiring the removal of

surface boulders within grubbing areas are designated as grubbing on the Quantity

Sheets, and not as removal of surface boulders.


May 2013 Page 4 of 4 B201-4

The calculated surface boulder areas are detailed on the Quantity Sheet. Entries are

listed by station and offset at each location where surface boulders (beyond grubbing

areas) are to be removed. All areas are totalled and the tender total transferred to the

Tender document.

When lump sum payment is chosen, the quantities are indicated on the Quantity Sheet

at each location where surface boulders are to be removed, as described above.

201-4.9.2 Piled Boulders

Piled boulders are shown on the plans using a hand-drawn symbol, and appropriately

labelled (e.g. "1.5 m Boulder Pile" or "0.5 m Fencerow"). The calculated quantities

are detailed on the Quantity Sheets. Entries are listed by station and offset at each

where piled boulders are to be removed.

All quantities are totalled on the Quantity Sheet and the total transferred to the Tender

documents.

When piled boulders quantities are small and removed under lump sum payment or as

part of other work, the locations are indicated on the contract drawings and entered on

the Quantity Sheet, listing each location and quantity where piled boulders are to be

removed.

DETAIL ESTIMATING MECHANICAL STUMP CUTTING

May 2013 Page 1 of 2 B201-6

B201-6 - MECHANICAL STUMP CUTTING - OPSS 201

201-6.1 GENERAL

Stump removal using a mechanical cutter is a chipping operation whereby tree stumps

are removed to a depth of 0.15 m below the surrounding area, leaving the root

systems undisturbed.

Under this tender item, only those stumps 150 mm diameter and greater are

considered for stump removal by mechanical cutter.

For innumerable small trees, those less than 150 mm diameter, close cut clearing is a

more practical and acceptable means of removing hazards or improving aesthetics.

Following are typical conditions under which stump removal by mechanical cutter is

considered desirable:

DETAIL ESTIMATING MECHANICAL STUMP CUTTING

May 2013 Page 2 of 2 B201-6

a) In urban areas, beyond grading limits, where grubbing is an unwarranted expense

and regular mowing a necessity;

b) Areas where underground utility installations are liable to damage from grubbing

operations;

c) Areas where grubbing operations may affect culverts, or undermine buildings,

sidewalks, pavement or shoulders;

d) Following clearing or close cut clearing - to remove hazards, permit mowing or to

improve aesthetics, without having to remove entire root systems, as is the case in

grubbing operations.

201-6.8 COMPUTATION

This is a Plan Quantity Payment item.

Computation procedures for mechanical stump cutting are the same as those for

206-1 - EARTH EXCAVATION (GRADING) - OPSS 206

206-1.1 GENERAL

This section deals with the excavation, haulage, placement and compaction, and disposal of earth material, as classified in OPSS 206. Earth excavation, usually, is the main component of highway construction, and includes grading for sideroads, entrances, ditches, detours, etc.

206-1.1.1 Classification of Earth Materials

The following materials, when encountered during grading operations, usually are treated the same as earth, and are included in the tender item "Earth Excavation (Grading)":

a) Earth Overburden

Stripping and Earth Cut quantities originating from earth overburden on rock formations are estimated and treated as earth excavation in accordance with the Regional Geotechnical Section's recommendation.

b) Boulders and Fragmented Rock in Earth Cuts

The treatment of boulders and fragmented rock smaller than 1.0 m3encountered in earth cuts is normally stipulated in the Geotechnical Report and, unless otherwise directed, they are dealt with as per Ontario Provincial Standard Drawings.

c) Fragmented Rock and Weathered Rock

Quantities of fragmented rock, smaller than 1.0 m3, excavated from existing road embankments or cuts will be included in "Earth Excavation (Grading)" quantities.

Certain rock deposits such as shale may be designated as earth to the bottom of excavation or to a designated pay line, below which it would be classified as solid rock.

d) Granular Deposits

Any granular or select subgrade material deposits which meet the requirements of OPSS 1010, when obtained from within the right-of-way, is paid for as "Earth Excavation (Grading)". Relevant estimating procedures and rates such as those for compaction, water, etc. apply equally to granular material.


96 05 B206-1-4

206-1.1.2 Tender Item

The tender item associated with highway grading in earth is:

Earth Excavation (Grading)

and includes material from the following operations:

Stripping in Cuts Stripping under Fills Earth Cut/Fill - roadway ) - side ditches ) - transition points ) - sidewalks ) Integral with - widening ) roadway Section - entrances ) - frost heaves ) - excavation below subgrade) Ditching - catch - interceptor - intake/offtake Swamp Excavation - roadway ) combined quantity - culverts ) Watercourse Correction Frost Heaves, isolated Sidewalks, isolated Commercial Entrances

The benching of existing sideslopes for roadbed widening in fills is a construction operation only; it is not to be computed for inclusion in this tender item.

206-1.1.3 Other Excavation Tender Items

Excavation for the following is not carried out under the item "Earth Excavation (Grading)", but under separate tender items and governing OPS Specifications:

Pavement Widening (linear measurement) Pipe Culverts Sewers, Manholes, Catchbasins, Ditch Inlets Subdrains Structures

These items are detailed elsewhere in this Chapter.


96 05 B206-1-5

206-1.1.4 Specifications

Details of the work of Earth Excavation (Grading) are contained in the following OPS Specifications:

OPSS 206 Grading General 209 Swamp Treatment 316 Expanded Polystyrene 351 Concrete Sidewalk

206-1.1.5 Special Provisions

The designer should investigate to determine whether Standard Special Provisions are required to be included in the contract.

206-1.1.6 Standard Drawings

To establish the physical limits on which to base quantities the designer should become familiar with the "Ontario Provincial Standard Drawings" - 200 Series.

The designer may be required to develop typical sections or modify existing standard drawings for specific situations, such as:

Sideroad Intersections Commercial Entrances Private Entrances Design of Open Channels

and should consult the following manuals, where appropriate:

Geometric Design Manual Commercial Access Manual Drainage Manual

206-1.2 COMPUTATION

This is a Plan Quantity Payment item.

In computing earth quantities - cut and fill - the designer will subtotal the figures every 350 m along the highway, and also on service roads, sideroads, detours, ramps and entrances where the length justifies such a breakdown. Each subtotal will constitute a single-line entry on the "Quantities - Grading" sheet.


96 05 B206-1-6

Where stage construction is proposed, quantities must be considered on a stage basis, as material excavated in one stage may not be available for fill purposes in a later stage. Separation of quantities may also be required for left and right sides of a widening project.


A. Design Criteria

This document contains the approved parameters governing the alignment and cross-section of the main roadway in a project.

B. Survey Information

Field notes are produced by survey crews, and provide details of existing surface features on the main roadway, sideroads and entrances, as well as data for the new horizontal and vertical alignments.

Cross-sections are recorded by survey crews, using rod and level, for plotting either manually or by machine. Surveys and Plans Office also provide cross-sections obtained by means of aerial photography.

C. Soils Profile

The Soils Profile shows the existing groundline, the proposed vertical alignment and the existing drainage data. Also shown are the relevant soils data and grading and granular base recommendations specified by the Regional Geotechnical Section.

D. Reports

A number of reports contain data needed by the designer to establish cross-sections upon which cut and fill quantities will be based. These reports are:

Geotechnical Report (Pavement Design Report) Preliminary Design Report Environmental Assessment Report Foundations Report

E. Field Review

206-1.2.2 Components of Earth Excavation (Grading)

A. Stripping


96 05 B206-1-7

Stripping consists of the removal of the upper layer of soil, which is predominantly organic and generally known as topsoil. It differs from the underlying material in that it is unsuitable for the construction of embankments - within the load supporting area of the 1:1 slope of the fill while, at the same time, it needs to be treated as a valuable commodity, to be stockpiled for later use in the contract as topsoil on graded areas, prior to seeding or sodding.

The depths of required stripping under fills and in cuts, also the percentage of stripping considered as suitable for use as topsoil, will be as recommended by the Regional Geotechnical Section, based on soils investigations and published in the Geotechnical Report.

(a) Stripping in Cuts

Cut stripping occurs when the subgrade is below the bottom of the stripping depth.

Topsoil is to be removed for the full width of the cut to the depth recommended in the Geotechnical Report. In the absence of any recommendation, a depth of 0.15 m is to be used.

It is not necessary to manually deduct the stripping areas beyond excavation backslopes from the computerized stripping areas.

(b) Stripping under Fills

(i) Stripping under Fills 1.2 m or less in height.

The height of fill is defined as the vertical distance between the top of granular base and the ground line.

Fill stripping occurs when the subgrade is above the bottom of the stripping depth.

The width of stripping under shallow embankments coincides with the width of the proposed embankment,i.e. toe to toe of slope. This does not include areas under embankments due to slope flattening.

Topsoil is to be removed to the depth recommended in the Geotechnical Report. In the absence of such recommendation, a depth of 0.3 m is to be used.

(ii) Stripping under Fills more than 1.2 m in height

Stripping is not required under fills higher than 1.2 m unless there is a shortage of topsoil, in which case the


96 05 B206-1-8

height limitation may be waived and the stripping area extended, rather than resorting to the more expensive operation of importing topsoil.

(c) Stripping in Areas to be Grubbed

Stripping is calculated for all areas to be grubbed within the grading limits. Excavated material is considered lost and not available for further use.

The depth of stripping in grubbing areas is that recommended by the Regional Geotechnical Section or 0.3 m, whichever is the greater.

(d) Stripping in Swamps

Stripping is not calculated in areas where swamp excavation or displacement is required.

(e) Stripping in Areas of Embankment Widening

In areas of reconstruction requiring embankment widening, stripping of previously constructed slopes is estimated using a depth of 0.15 m, or as recommended in the Geotechnical Report.

(f) Stripping of Sideslopes Prior to Benching

Although benching of sideslopes is not a measured quantity, stripping is computed over the benched area to the depth recommended in the Geotechnical Report. If no depth is recommended, a depth of 0.15 m is to be used.

Note: On projects where all of the excavated earth is unsuitable for embankment construction, or where there are no embankments to be constructed, and there is no need to salvage stripping material for topsoiling, then stripping over cuts need not be computed.

B. Earth Cut for Roadways, Interchanges, Detours, Sideroads, Entrances and Sidewalks.

Earth Cut is material classified as earth as per OPSS 206, and which is excavated from below the stripping down to s
