The discussion on material supply shall include the City project material list and the

supply source. It shall be the Contractor’s responsibility to review the list and advise

within 24 hours of the Pre-Job Conference if modifications to the material list are

required.

7. EXCAVATION

7.1 General

The Contractor shall make all machine and hand excavations necessary to install the

underground structures and equipment to the alignment and depths indicated by the

Project Specifications and the City's representative.

Before excavation through heavy asphaltic or concrete surfaces, the surface shall be cut in

a straight line with abrasive wheel or pneumatic spade equipment to a nominal 150 mm

outside of the limits of the excavation.

7.2 Proving Route

Grades of the trench, ducts, and structures shall be proven far enough along the route in

advance of duct laying or forming and concreting that any relocation or redesign

necessitated by unforeseen obstacles may be carried out.

It is essential that the Contractor prove the location of any existing utility by digging test

holes or other equivalent method satisfactory to the City's representative. The Contractor

shall not install a chamber until the next chamber has been fully excavated, and the

intervening duct line proven feasible. Any ducts or chambers constructed by the

Contractor in contravention of these requirements, and which have to be relocated or

redesigned because of an unforeseen obstacle along the route, shall be demolished,

removed from the site, and replaced at the Contractor’s expense.


Page 5 of 18

7.3 Basis of Tender

Unless otherwise specified in the Project Specification, the Contractor shall prepare

Tenders on the basis that the entire excavation will be common excavation and will be

immediately removed from the site.

The Contractor must also quote unit prices for rock excavation and extra common

excavation as defined herein. These unit prices shall include removal of excavated

material.

7.4 Material Definitions

All excavated material shall be classed as either "common excavation" or "rock

excavation" as defined in the following paragraphs:

(a) Common Excavation

Common excavation will include such materials as are commonly called earth,

loam, clay, muck, sand, gravel, gumbo, boulders each less than 1 m³ in void, angular

rock fragments, hardpan, pavement, and all other materials of every description not

defined as "rock excavation".

(b) Rock Excavation

The term "rock" is hereby defined as:

(i) Solid formations of dense homogeneous sedimentary or igneous material

which require, in the judgement of the City's representative, the continuous

blasting, drilling or wedging for their removal. In order to qualify for

payment under the unit price for rock excavation, material so removed shall

measure at least 1 m³ in void within the limits of excavation as defined

herein.

(ii) Individual boulders of any type measuring at least 1 m³. Payment for

excavation of this type of material shall be based upon the amount in cubic

metres of boulders removed within the limits of excavation as defined herein.

The breaking and removing of road or sidewalk pavements or frozen material,

regardless of thickness, will in no case be taken as rock excavation.


Page 6 of 18

7.5 Unit Price Excavation

The Contractor will be additionally compensated for any "rock excavation" or extra

"common excavation" removed from the trench in accordance with the relevant Unit

Price. Measurement for payment of additional or deleted quantities of excavation will be

as defined in the "Basis of Measurement" clause below.

If, after obstructions have been proven or after any trench has been excavated, the City's

representative should decide to change the depth or location of any trench or structure, the

Contractor will be paid for any additional excavation (but not that excavation included in

the "Basis of Tender" clause above) according to the volumes excavated, as defined in the

"Basis of Measurement" clause below. However, no allowance will be made for any

additional excavation unless the change in grade exceeds 150 mm.

Similarly, if the City's representative should change the depth or location of any trench or

structure thereby reducing the necessary excavation, the cost of deleted excavation will be

deducted from payments owing the Contractor; however, no deduction will be made for

any deleted excavation unless the change in grade exceeds 150 mm.

7.6 Basis of Measurement

(a) Common Excavation

(i) Trench Work

Volume measured in void with the excavation limits set at 75 mm below the

duct bank sub-grade and 150 mm outside each side of the duct bank,

including any concrete encasement, as shown on the drawings, except that

where the safety shoring recommendations of WorkSafe BC require

additional width of trench to install such shoring, then the payment shall be

based on these widths.

(ii) Chambers

Volume measured in void with the excavation limits set at 100 mm below

sub-grade and 300 mm outside each side of the chamber outline as shown on

the drawings.

(b) Rock Excavation

(i) Trench Work

As excavated - with the excavation limits set at 75 mm below the duct

bank sub-grade and 150 mm outside each side of the duct bank,

including any concrete encasement, as shown on the drawings, except

that the maximum allowance for width shall be in accordance with

WorkSafe BC recommended practices.


Page 7 of 18

(ii) Chambers

As excavated - with the excavation limits set at 100 mm below sub-

grade and 300 mm outside each side of the chamber outline as shown

on the drawings.

Where rock excavation is required above the sub-grade of the duct banks or

chambers, as shown on the drawings, the Contractor will be paid only at the unit

rock excavation price quoted in the Tender. Where rock excavation is required

below the aforementioned sub-grades, the Contractor will also receive the unit

common machine excavation price quoted.

7.7 Subsurface Structures

The drawings show the available information on the type and location of existing surface

and subsurface structures and utilities. Neither the accuracy nor the completeness of this

information is guaranteed.

If the location of such a utility is not as shown on the drawings, but requires that the

underground structures be installed either above or below the utility, then the only unit

price adjustments allowable will be those for additional excavation and backfill.

The Contractor shall be responsible for locating and exposing all buried utility services;

building around, under, or over these services, and taking proper precautions against

accidental damage; temporary supporting where required and removing such supports

upon completion; and maintaining specified clearance between services and the

underground structures.

7.8 Removal of Obstructions

After the excavation is opened and all pipes and other obstructions are exposed, the City's

representative shall be notified that the excavation is ready for examination. Should the

City's representative decide any pipes or other structures excluding pavement at the same

elevation as the trench require moving, the expense of such moving will be borne by the

City, but the Contractor will have no charge against the City by reason of delay so

occasioned, nor shall the Contractor be held responsible for any delay in completion of the

work due solely to the above cause.

If the Contractor wishes to temporarily remove, disconnect, or relocate service pipes

crossing the excavation to facilitate installation of the underground structures, they shall

make their own arrangements with the owners of the service pipes and shall bear all costs

of such temporary work. The City will neither guarantee that such temporary work may be

done nor bear any cost of such temporary work. Payments for all such temporary work

shall be made directly by the Contractor.

Disconnected or abandoned utilities shall not be removed or salvaged without the

permission of the City's representative.


Page 8 of 18

7.9 Irregularities in Excavation

All irregularities and cavities in the bottom of the trench or excavation shall be filled up to

the required sub-grade with approved backfill material properly tamped in place.

7.10 Adjacent Structures and Properties

Prior to excavation, the Contractor shall consult and cooperate with owners of adjacent

structures which may be endangered, or whose gardens, trees, tree roots, and shrubs

require protection or alteration during construction, to eliminate future dispute and

litigation over that which may already be in a damaged condition. Under no circumstances

shall the Contractors permit their forces, materials, and/or equipment to encroach on

private properties adjacent to the work, without the express consent of the City's

representative. Any survey pins displaced during the construction work shall be reinstalled

by a legal surveyor at the Contractor's expense.

7.11 Drainage and Shoring

The Contractor shall, without additional charge, construct such temporary drains or do

such dewatering of the trench and chamber excavations as may be necessary to keep water

away from concrete work until the concrete has thoroughly set.

Without additional charge, the Contractor shall provide and place adequate shoring as

required by WorkSafe BC and as required to protect adjacent paving and structures, and to

prevent any sloughing in of material that is under adjacent sections of sidewalk, road

pavement, pipes, or ducts.

8. UNDERGROUND DUCTS, CHAMBERS, AND TRANSFORMER PADS

The location, number, and arrangement of ducts, chambers, transformer pads, and service boxes

shall be as shown on the drawings. Ducts may be directly buried, concrete encased, or a

combination of both as specified on the drawings. The size, shape, routing, and concrete

encasement of ducts between terminations may be varied by the City's representative according

to space available in the street or the obstructions encountered as may be determined after the

trench is excavated.


Page 9 of 18

9. PROTECTION OF FOREIGN UTILITIES

In the performance of the work, care shall be taken not to move, without consent of the proper

parties, any structure, and in crossing or running parallel with any structures they shall be

secured in place until the work is completed. Any damage to structures of any kind, caused by

neglect to attend to such structures, shall be paid by the Contractor.

The Contractor shall build around, under, over, or through pipes, sewers, culverts, catch basins,

or any other structure encountered in the line of the work, or shall divide the ducts so as to lay

part on each side either horizontally or vertically or both, of any such structure, as required by

the City's representative, and shall supply such materials and make such alterations, substitutions

and repairs as may be required for such work. Whenever concrete duct bank is so divided, each

part must have a full concrete envelope 75 mm in thickness.

10. DUCT INSTALLATION

10.1 URD/UD Class Ducts

It is recommended that excavation for transformer pads be completed and trenching

extended from the respective pads. This permits duct bends to be secured and tamped in

the pad subsurface and duct laying can proceed therefrom in the excavated trench.

In locations other than where native soil is a fine sandy material completely devoid of

rocks or small stones, a 75 mm layer of sand shall be placed in the bottom of the trench.

The plastic duct shall be either direct buried or encased in concrete as shown on the

drawings. All joints shall be cemented and joined in an approved manner. Duct runs

except stubbed off sections shall be terminated with preformed bell ends and plugs. The

caps installed on stubbed off service ducts shall not be cemented, however, caps shall be

cemented on main runs intended for future extension.

10.2 Feeder Ductbanks

The Contractor shall build complete forms to the full height of, and on each side of every

duct bank, before pouring concrete or laying duct. Forms shall be made rigid and shall be

adequately braced to prevent bulging or movement. All duct banks shall be poured on a

minimum 50 mm thick bed of 40 mm minus drain rock, supplied and placed by the

Contractor without additional compensation.

Duct banks shall be installed in accordance with the following procedure:

(a) After the grade of the trench has been checked by the City's representative, a 75 mm

base of stiff concrete shall be poured in sufficient quantity that the bottom row of

ducts may be laid before the concrete has attained its initial set.

(b) The duct shall be checked for defects in material and structure before being placed

in the trench. Any field-cut ducts or bends shall have their inside edges bevelled

smooth by sanding. The bottom row of ducts shall then be laid, with open ends


Page 10 of 18

closed with plugs secured to prevent removal by hand. Any work done to repair or

connect to existing transite ducts must comply with approved methods and

regulations for working with asbestos cement duct.

(c) For 4-inch and 5-inch ducts, a separation of 45 mm, both vertically and horizontally,

shall be maintained between ducts by the use of approved separators of the correct

dimensions. However, vertical separation shall be increased to 115 mm before

entering a manhole, unless otherwise noted on the drawings. Increase in vertical

separation shall begin a minimum of 6 m back from the outside face of the manhole.

(d) The duct joints shall be staggered at least 150 mm from neighbouring duct joints in

both the vertical and horizontal rows.

(e) After the alignment has been checked by the City's representative, the concrete

sheathing and fill shall be poured around the ducts to the level set by the City's

representative. The Contractor shall ensure that the correct duct separations and

thicknesses of concrete are maintained at all times.

(f) The separators shall then be removed and the holes filled with concrete.

(g) The next horizontal row of ducts shall then be laid and the same procedure repeated

until the required section is obtained and the top 75 mm concrete sheathing is

complete.

(h) The ends of ducts in a run, which will be extended later, shall be staggered and shall

extend at least 300 mm beyond the end of the concrete envelope. The open ends of

these ducts shall be closed with caps cemented in place.

10.3 Mandrelling and Duct String

(a) URD/UD Class Ducts:

The ducts shall be proven clean and free of obstructions or faulty joints by use of a

Greenlee Piston or an acceptable combination of mandrell, swab, and wire brush to

the satisfaction of the City's representative.

(b) Feeder Class Ducts:

When the duct work is completed and the concrete and mortar thoroughly set, a test

mandrel shall be drawn through each duct in the presence of the City's

representative. The test mandrel will be comprised of a wire brush, cutter and disc

type mandrel (General Machine Products attachment Part No. 25, Cat. No. G-1011,

followed by Part No. 27 or equivalent, sized according to the duct). The minimum

diameter of such mandrels shall be 0.5 inch below the nominal duct size.

After test-mandrelling, an approved light waterproof cord shall be left through all ducts or

as designated by the City’s representative.


Page 11 of 18

10.4 Feeder Duct Measurements

Duct measurement shall be from centre to centre of chamber covers, or centre of chamber

cover to centre of terminal poles, measured horizontally, less the distance from centre of

chamber cover to face of duct where it enters each chamber.

After formwork is completed care, shall be taken in placing concrete for wall cavities.

Concrete lifts for such cavities shall not exceed 300 mm and concrete for such lifts shall

be first placed on the manhole roof form or a pouring deck before placing into wall

cavities. Concrete shall not be poured directly into wall cavities. Wall pours must be

continuous until completed.

The top of the chamber roof and the chamber casting shall be set to conform to the line of

the street or as otherwise determined by the City's representative. Manhole openings shall

have a 75 mm chamfer at the bottom. Manholes are normally built with a brick chimney,

cement rendered inside and out, extending from the chamber roof slab to the underside of

the cover castings to allow for any subsequent lowering of street grade. Cement bricks or

equivalent materials are to be supplied and installed by the Contractor for this purpose as

required by the City's representative. The Contractor shall also install a 250mm

ventitaliton hose casting in a manner similar to the manhole lid.

(v) Under wet conditions, at the discretion of the City's representative, the above

150 mm layer of drain rock shall be increased to 200 mm.

(b) Placing

(i) Manhole sections shall be placed with great care. The responsibility of off-

loading and placing manholes (or sections) into excavations shall be the

Contractor's. Care shall be taken to maintain adequate clearances from hoist

booms to overhead conductors.

(ii) Gaskets - Care shall be taken to place precast sections so that gaskets between

sections are totally contained and compressed.

(iii) Sumps - A suitable sealing grout shall be placed, at the the City

representative's direction, between sump and base of manhole.

11.4 Duct Terminations

The Contractor shall terminate all ducts with bell ends installed 75 mm back from the

inside face of chamber walls when poured in place (25 mm back when precast), and shall

finish the recesses with chamfered edges in a clean and workmanlike manner. For precast

manholes any wall openings shall be filled with concrete to the satisfaction of the City's

representative.

Where the drawings indicate a future duct bank on any face of a chamber, a brick window

100 mm thick, cement rendered both sides, shall be provided.

11.5 Chamber Designations

Each manhole lid shall be permanently identified by the Contractor with the letters CNWE

and the manhole number (MHXXX).

Secondary service boxes shall be identified with the letters CNWE only.

or as required by the City's representative.

(b) All drainage pipe, valves and P-traps shall be provided by the Contractor.

(c) Connection of drains to City sewers or catch basins will normally be done by the

Contractor. Drainage excavations shall then be back-filled to the same standards as

set for duct excavation. All costs of installing and backfilling drains shall be

included in the lump sum bid price. Under no circumstances will laying of drains as

shown on construction drawings be considered as unit price or extra work.

11.8 Removal of Forms and Traffic Loading

Inside roof forms of poured-in-place chambers will not be removed for a minimum of 14

days if the chamber is in the sidewalk and 21 days if in the travelled road.

Poured-in-place chambers shall not be subjected to traffic loading for 21 days unless

otherwise directed by the City's representative.

12. BACKFILL

12.1 General

with these Tender Documents, and the clean-up after backfill.

Backfill will normally be imported granular or sand material (see below). However, native

materials may be used, at the City representative's discretion, if location and soil

conditions are considered satisfactory, and/or if specified in the Project Specifications.


Page 14 of 18

12.2 Backfill Materials

Unless otherwise specified in the Project Specifications or by the City's representative, the

excavation shall be backfilled as follows:

(a) To 150 mm above direct buried ducts or 200 mm above concrete encased ducts with

approved sand, hand tamped. A portable plate vibrator may be used at the discretion

of the City's representative.

(b) From the point specified in (a) above to the point specified in (c) below with any of

the following materials, providing all materials are compacted in accordance with

the compaction clause below. Backfill shall be done in maximum lifts of 300 mm

(loose) for imported material or 150 mm to 200 mm (loose) for native material

unless otherwise specified by the City's representative. Warning tape reading, as a

minimum, "Caution Buried Electric Line Below" shall be supplied and installed by

the Contractor at a depth of 300mm below finished grade.

Sand shall be free of organic materials, clay or silt. 100% shall pass a 5 mm

sieve, 90 – 100% shall pass a 2 mm sieve and not more than 5% shall pass a

75 m mesh sieve by mass. Fraser River pump sand is acceptable.

(ii) Combined Crushed Aggregate Fill

This fill shall be free from organic materials, clay or silt. The fraction retained

on a 10 mm sieve shall be at least 50% crushed. The fraction passing a 75 m

mesh sieve shall be not more than 5% by mass.

(iii) Select Backfill

This material shall be essentially granular and shall not contain stones larger

than 75 mm, organic material, silt or clay. The fraction passing a 75 m mesh

sieve shall not be more than 5% by mass.

(iv) Native or Random Backfill

This material may be used, if the required compaction can be obtained.

Compaction ability is very dependent upon water content and to obtain

approval for use of this material the Contractors may be called upon to

demonstrate their methods and machinery to prove to the City's representative

that the compaction requirements can be met. In any event, all stones larger

than 150 mm must be removed.


Page 15 of 18

(c) The top zone of the excavation shall be backfilled with 300 mm of 20 mm minus

combined crushed aggregate fill where the excavation is situated in a paved or

travelled road; 150 mm of 20 mm minus combined crushed aggregate where the

excavation is situated in a sidewalk; 150 mm of black loam where the excavation is

situated in a developed grass boulevard. All these materials shall be thoroughly

compacted after placement.

(d) In all locations where road paving or sidewalk has been removed for trench

excavation the Contractor shall, unless otherwise directed, supply and place a

temporary tamped asphalt patch within 24 hours of backfilling to facilitate the

movement of traffic and pedestrians until permanent repairs are made. Compacted

thicknesses shall be 50 mm for roads and 25 mm for sidewalks.

(e) In all locations where the excavation is located in developed grass boulevards, the

Contractor shall neatly cut the grass sod and store it in a suitable location. After

backfill is completed the black loam shall be leveled off, raked clear of stones and

debris and the grass sod replaced. If the Contractors damage the adjacent grass, or

are unable to preserve the grass sod, they shall resod the boulevard. The Contractor

shall be responsible for maintaining sod until it has grown to a condition similar to

that existing before excavations were begun. If, in the opinion of the City's

representative, the time of year is not suitable for resodding, the Contractor will be

required to carry out this work at a more seasonable time.

(f) Backfilling of all voids around chambers shall be done with river sand or other

approved material.

The supply and placement of all the above backfill materials including the supply and

placement of sand for the minimum cover over all ducts, and the disposal of any native

excavated backfill materials, shall be the responsibility of the Contractor, and shall be

included in the Contractor's lump sum tender.

total sample,

Pf = percent of total sample passing the No. 4 sieve,

Df = maximum dry density in pounds per cubic foot (ASTM D1557-

66T) for material passing the No. 4 sieve,

Pt = percent of total sample retained on the No.4 sieve,

G = bulk specific gravity (dry basis) of material retained on the No. 4

sieve (ASTM C127-59).

Upon request of the City's representative, the Contractors shall, at their own expense,

provide certified test results demonstrating that the above compaction requirements have

been met.

12.4 Unit Price Work - Backfill
