3.11.1
Pole Brackets
Brackets shall be installed as specified by the manufacturer and as shown
on drawings. Mounting hardware shall be sized appropriately to secure the
mount, luminaire, and housing with wind and ice loading normally
encountered at the site. [CCTV luminaires shall be located inside the
perimeter zone and at a minimum of 9 m 30 feet vertically above the
finished grade.] [When security lights are used along roadways, brackets
shall correctly position roadway luminaires and fresnel-lens luminaires not
less than [1.2] [1.8] [2.4] [3.1] [3.7] or [4.6] m [4] [6] [8] [10] [12]
[or] [15] feet from the pole, at not less than the mounting height
specified by the fixture manufacturer.] Pole brackets for floodlights
shall have the number of tenons indicated, arranged to provide the
indicated spread between each tenon. Where indicated on drawings,
adjustable heads shall be installed on the brackets to position the
luminaires. Identical brackets shall be used with one type of luminaire.
3.11.2
Concrete Foundations
Concrete foundations shall have anchor bolts accurately set in the
foundation using a template supplied by the pole manufacturer. Once the
concrete has cured, the pole shall be set on the foundation, leveled on the
foundation bolts, and secured with the holding nuts. The space between the
foundation and the pole base shall be grouted. Concrete and grout work
shall conform to Section 03300A CAST-IN-PLACE STRUCTURAL CONCRETE.
Concrete shall be 21 MPa 3000 psi at 28 days.
3.11.3
Rigid Steel Conduit Ells
Rigid steel conduit ells shall be provided [at all poles] [where specified
or indicated on drawings]. Rigid steel conduit shall be connected to the
ells and shall extend to a minimum height of 3 m 10 feet above grade.
Rigid steel conduit ells shall be provided for wood poles, where required

Wood Pole Installation
**************************************************************************
NOTE: Where specific pole setting depths cannot be
given because the type of soil is not known, use the
second bracketed choices; otherwise detail
requirements.
**************************************************************************
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 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
