conduits at the time of installation. Unused openings in sheet steel panels shall
be plugged with press-in plugs. Spare conduits shall be capped.
c-35
i)
Concrete Pole Bases
Whe¡e possible, the hole for the base shall be dug without disturbing the
surrounding soil. If the soil remains firm and hole rlimensions conform to those
specified, no form work need be used except for the top 200 mm of the base.
The pedestal portion of the base shall be neatly formed to the given dimsnslottr.
The top of the base shall be trowelled smooth and level, and edges shall be
bevelled.
An accurate template shall be used to locate conduits and pole anchors.
Anchor bolts shall be set with a template to suit the poles.
Poles shall not be mounted until 7 days after pouring bases.
Before mounting poles, all formwork shall be removed and baclfill placed
around the base and compacted with a mechanical tamper to 90 percent of
Standard Proctor Density (ASTM D698).
Bases shall be neatly grouted after pole installation ensuring that drain holes are
not plugged. Temporary protective covers shall be provided over any concrete
pole base which has exposed wiring prior to the installation of the steel pole.
Poles
Poles shall be erected plumb, using the shims supplied if required. Plumbing
shall be done with a 600 mm spirit level attached to a proper size wedge to allow
for taper of poles. No more than 6 shims shall be used for Írny one pole. Davits
and mast arms shall be installed at right angle to the centreline of the road.
Poles shall be cleaned after erection.
E4posed portions of the anchor rods and nuts shall be given a liberal coating of
Dearborn Chemical Company No-Oxide Grease Type "G Special".
Arrangements shall be made by the Developer to de-energize high potential
conductors that are too close to roadway lighting poles during erection. The cost
for this shall be borne by the Developer.
If temporary protection is required for erection of works where overhead
conductors of 600 volts or less or telephone cables are in contact with or in
danger of contacting roadway lighting poles or luminaires during erection,
adequate polyethylene conduit sleeves securely taped into place shall be installed
to protect the overhead conductors.
k)
c-36
The Developer shall be held responsible for and bear the cost of damages done
to other facilities caused by this operation.
t)
Luminaires
Luminaires shall be cleaned and levelled after pole erection and plumbing is
complete.
Luminaires shall be securely fastened to the lighting poles, and oriented to
produce the required light distribution.
m)
Photo-Electric Controller
Photo-electric controller shall be oriented as required by the manufacturer.
n)
Painting
After completion of the pole installation, the Developer shall wire-brush any
paint defects to be followed by application of a coat of paint.
Poles and service bases shall receive a final coat of spray paint, the color of
which shall be as specified by the District.
Surfaces shall be completely dry before painting. Work shall not be done in
temperatures lower that LO"C or when frost is predicted within the next 24 hours.
Existing metal poles, service bases and other materials which are part of the
project shall be cleaned, wire brushedwhere the paint is damaged and repainted.
o)
Clean-up
The interior of enclosures, pole handholes, and wiring areas shall be cleaned of
dust, dirt and loose materials, vacuum-cleaned, and all water and moisture
removed.
All fastening screw holes provided in enclosures shall have a fastening screw
installed.
c-37
p)
Testing and Calibration
L.
General
The Contractor shall carry out all adjustments and tests necessary to
ensure that the entire electrical installation and all its equipment material
and components are in satisfactory physical condition electrically and
perform the intended function and operations. Adjustments required to
make the system operate in the manner intended by the District shall be
made at no cost to the District of Mackenzie.
At the completion of the job, proper systems operation shall be
demonstrated to the District.
2.
Conductors
After conductors have been drawn into raceways, but before the
conductors are connected or spliced, they shall be checked for insulation
resistance, continuity, and freedom from short circuits and grounds.
3.
Voltages
Single-phase, 3-wire systems shall be checked to ensure that proper
voltage exist between each phase and neutral, ffid between phases.
Three-phase circuits shall be checked to ensure that phase voltages are
equal, and that phase to neutral voltages are equal and correct on three-
phase systems.
UNDERGROUND WIRING
General
The Developer shall cause BC Hydro to install electrical distribution systems to service
all parcels in his subdivision, such systems to the standards required by BC Hydro; the
Developer shall also install roadway lighting as required by this bylaw.

tested sholl be filled with woler ond oll oir expelled from the piping. lt is
recomn¡ended thot the test section be filled with woter for ot leost 24 hours
prior to teslíng. By pumping woter into the fest section, the pressure within
the piping shotl be increosed to 0.7 lvlPo or l-l/2 times the system operoting
pressure of the point of test, whichever is lhe greoter. This pressure sholl be
mointoined constontly in the pipe througho.tt fhe durotion of the test by the
oddition of mokeç woter. The durotion of the test sholl be o minimum of 2
hcr¡rs. The quontity of woter pumped into the test section to mointoin the
specified pressure over the period of test sholl be considered to be the
leokoge.
Piping will not be occepted until the leokoge is less thon the moximum
ollowoble leokoge determined from the following formulo:
L = ND x the Squore Root of P in which
4060
L = the rumber of bolted, mechonicol or push-on joints in the test section
D = the nominol diometer of the pipe in millimetre, ond
P = the oreroge test pressure during the leokoge test ïn nngoposcols.
Should ony tesf disclose leokoge greoter thon fhot specified obove, the
Dweloper sholl læoTe ond repoir the defect ond retest the section to ensure
thot the leokoge is within the ollowoble limits.
For o section of pipe instolled wifh couplings, the number of joints ore equol
to the number of pieces of pipe.

Ð Ca¡tion in Excorotion
Trenches sholl be excovoted only qs for ín odvonce of fhe pipe lq¡ing
operolion os sofety, troffic, ond weother condìtionss permit. Ccn¡fion sholl be
exercised with respect to strucfures, piping, or olher rnonmode obstocles thot
moy exist within the working oreo ond d.¡e corsiderqtion given to lhe
protection ond supporf of such properfies ond structures.
Precuttínq Foved Su rfoces
When trenching olong or ocross o poved surfoce, povemenf shqll first be cut
by hord or rnechonicol meons in stroight lines porollel to the trerch
cenfreline. the totol cut width of povement sholl not be greoter lhon thot
which is necessory for trench excorotion under existing soil conditions ond
sholl not, in ony cose, exceed the specified rmximum trerch width of lhe
grourd surfoce shown on the drcwings. Where, ìn theopinion of theDistrict,
existing povement is in such poor condition fhot precutting is not worronted,
povement mq¡ be cut by lrerching equipment. Po¿ement lhot hos been
removed topermit trenching shqll be disposed of os wosle moteriol ond sholl
not be plcced in the trerch bockfill.
Excorated Trench Moteriol
Excqvofed trench moteriol rrny be piled olorgside the trench prorided the
working spæe is odequote for this purpose ond provided thot by so doing the
bockfill moteriol does ml spill onto privote properties odjocent to line of
trench thereby disturbing fences, buildings, shrubs, lowns, or other items of
volue.
Piling of excovoled rrnteriol olorg the trench sholl nof unduly restrict cross
troffic qt rood intersections. Moteriol sholl be cleored from rood
interæctiors md provisíon mode for use of the cross rood by troffic crs soon
os possible ofter exco¿otion hos tqken plæe. Pedestrion troffic to individ.¡ol
properties sholl be mointoined ot oll tirnes ond timber bridges sholl be
provided where it is necessory to cross open trenches. Roodwoys, drivewoys,
ond droinoge focilities sholl not be blocked unnecessorily. The spoil pile sholl

the Workerst Compensotion Boord or os moy be necessory lo protect life,
property, ond structures odjocent to the work, the work itself, or to mqinloin
trench width within the specified limits. Trench sheeting ond brocing sholl be
locoted no closer lhon 150 mm þ the widest section of ony instolledpipe.
Whenever possible, verticol trench timber or sheeting sholl be plæed so thot
it does r¡ot extend below the springline of thepipe beirrg instolled. When it is
necessry to ploce sheeting or timber below the pipe spríngline, os in the cose
of overexcovotion for trench bottom stobilizotion, sheeting sholl be roised in
600 mm lifts ond oll bockfill plæed below the level of the pipe sprîngline
sholl be thora.rghly compocted on eoch lifl to fill fhe void left by the roising
shee ting.
Trench sheeting ond brocing sholl be removed where its rernovol will not
result in domoç to odjæent structures, othenrrisg it sholl be left in plcce.
When sheeting ond broðing is lefl in ploce, it sholl be cut so thot no sheeting
remoins closer thon 900 mm to existing ground surfcce.
Where sheeting or timber is remo¿ed from o trench in which bockfill 's to be
compæted, itsholl be removed in o monner which permits compoctîon of the
bo'ckfill in lhe monner specified.

Precr¡tt irrg Poved Su rfæes
When trenching olorg or ctcross o poved surfoce, povement sholl first be cut
by hond or mechonicol meons in stroight lines porollel to fhe trer¡ch
centreline. The tolol cut width of povement sholl not be greoter thqn thot
which is necessory of trench exco¡qtion urder existing soil conditions ond
sholl not, in ony cose, exceed the specified rnoximum trench width of the
grotnd surfoce shown on the drowings. Where, in the opinion of the Districtt
ãxisting porernent is in such poor condition thot precutting is not worronted,
poremeni mcry be cut by trenching equipment. Pqvement thot hos been
removed topermit trenching sholl be dispoæd of os woste moteriol ond sholl
r¡ot be plcced in the trerchbockfill.
Excot¡oted Trench Moteriol
Excovoted trench rrnteriol rmy be piled olorgside the trench provided the
working spcce is odequote for this purpose ond provided thot by so doing the
bockfili moteriol does ml spill onto privote properties odjocent to line of
trench lhere disturbing fences, buildings, shrubs, lowns or other items of
volue.
Piling of exco¡oted moferiol olorg the trench sholl not unduly restrict cross

olso thot street entrqræes to drivewoysore not blocked f ¡om vehiculor troffic
for periods in excess of one doy.
Where excovoted rncteriol connot be piled olorg the trench in complionce
with the obove restriclions, it shall be trucked to locotions where bockfilling
is lokirç ploce or trucked to stockpile for return to the trerch ot the time of
bækfilling. Alternqtively, excoroted moieriol sholl be wqsted ond reploced
with opprwed moteriol ot time of bockfilling.
Trench Widths
Trenches shqll be exco¿oted such thot there is no less fhon 150 mm cleoronce
between the outside of the pipe ot its lorgest section ond the trench sheeting
or eorth woll, ond no more thon 375 mm cleoronce between thepipe ond the
eorïh woll rego rdless of the existence of trench support work. The obove
conditions sholl govern from the bottom of the trench to o distonce 100 mm
obove the top of the pipe ot its lorgest sectim. Trench widths obove this
level sholl be rrnintoined within the ollowoble limifs shown on the opprored
d rcwings.
Ledge rock, boulders, ond lorge stones sholl be removed to provide o
cleqrorce of qt leosf 150 mm belowond on ollsides of the pipe ond fittings.
O Brqcing qd Sheeting
Trenches shqll be sheeted ond broced in occordonce with the requirements of
the Workerd Compensotion Bærd or qs moy be necessory to protect life,
property, ond structures odjocent to the work, the work itself, or to mointoin
trench widths within fhe specified limits. Trench sheetÍng qnd brocing sholl
be locoted no doær thon 150 mm to the widest sectionof ony instolled pipe.
Whenever possible, verticol trench timber orsheeting sholl be ploced so thqt
it does not extend below the springline of thepipebeing insfolled. When it is
necessrry to ploce sheeting or timber below the pipe springlirre, os in the cose
of overexcorotion for trench bottom stcbilizotion, sheeting shall be roised in
600 mm lifts ond oll bqckfill plcced below the level of the pipe springline
sholl be thoroughly compocted on eoch lift to fill thevoid left by the roising
sheeting.
Trench sheeting ond brocirg sholl be removed where its removol will not
result in domoge to odjæent structures, othenvise it sholl be left in plcce.
When sheeting ond brocirg is left in ploce, it sholl be cut so thot no sheeting
remoins closer thon 900 mm to existing grourd surfoce.
Where sheeting or fimber is remo¡ed from o trench in which bqckfill is to be
