below for other lines, and no branch shall overhang horizontal clearances.
Where trees are indicated to be removed to provide a clear right-of-way,
clearing is specified in Section 02231 CLEARING AND GRUBBING.
3.1.4
Disposal of Liquid Dielectrics
PCB-contaminated dielectric shall be marked as PCB and transported to and
incinerated by an approved EPA waste disposal facility. The Contractor
shall furnish certification of proper disposal. Contaminated dielectric
shall not be diluted to lower the level of contamination.
3.2
POLE INSTALLATION
Joint-use electric/roadway-lighting poles for overhead electric and
communication lines shall be [wood][steel][concrete] poles utilizing
[armless] [crossarm] construction. [Cluster-mounted] [Cross-arm mounted]
banked single-phase transformer installations shall be provided. [Crossarm
construction shall be provided for support of other equipment, except where
direct-pole mounting is indicated.] [Pole equipment mounts shall be used
for steel and concrete poles and may be used for wood poles rather than
crossarm equipment mounts. Detail drawings shall be submitted for
approval.] Provision for communication services is required on pole-line
construction, except where specifically noted otherwise. A vertical pole
space of not less than [600 mm 2 feet] [_____] shall be reserved at
[indicated] [all] locations.
3.2.1
Wood Pole Setting
**************************************************************************
NOTE: Where specific pole setting depths cannot be
given because the type of soil is unknown, use the
second bracketed choice; otherwise detail
requirements.
**************************************************************************
Wood Pole Setting: Wood poles shall be set straight and firm. In normal
firm ground, minimum pole-setting depths shall be as listed in Table II.
In rocky or swampy ground, pole-setting depths shall be decreased or
increased [as shown] [respectively in accordance with the local utility's
published standards and as approved]. In swampy or soft ground, a bog shoe
shall be used where support for a pole is required. Poles in straight runs
shall be in a straight line. Curved poles shall be placed with curvatures
in the direction of the pole line. Poles shall be set to maintain as even
a grade as practicable. When the average ground run is level, consecutive
poles shall not vary more than 1.5 m 5 feet in height. When the ground is
uneven, poles differing in length shall be kept to a minimum by locating
poles to avoid the highest and lowest ground points. If it becomes
necessary to shorten a pole, a piece shall be sawed off the top end and
roofed. If any pole is shortened after treatment, the shortened end of the
pole shall be given an application of hot preservative. Where poles are
set on hilly terrain, along edges of cuts or embankments, or where soil may
be washed out, special precautions shall be taken to ensure durable pole
foundations, and the setting depth shall be measured from the lower side of
the pole. Holes shall be dug large enough to permit proper use of tampers
to the full depth of a hole. Earth shall be placed into the hole in 150 mm
6 inch maximum layers, then thoroughly tamped before the next layer is
placed. Surplus earth shall be placed around each pole in a conical shape
and packed tightly to drain water away from poles.
