SECTION 26 56 13.00 40 Page 15

] a. Steel Reinforcing

Reinforce prestressed concrete pole shafts with steel prestressing members, designed to provide internal longitudinal loading by either pretensioning or post tensioning of longitudinal reinforcing members.

b. Tensioned Reinforcing

Tension primary reinforcement steel used for a prestressed concrete pole shaft between 60 to 70 percent of its ultimate strength, with the amount of reinforcement being such that when reinforcement is tensioned to 70 percent of its ultimate strength, the total resultant tensile force does not exceed the minimum section compressive strength of the concrete.

c. Coating and Sleeves for Reinforcing Members

Where minimum internal coverage cannot be maintained next to required core openings, such as handhole and wiring inlet, protect reinforcing with a vapor proof non-corrosive sleeve over the length without the 13 mm 1/2-inch concrete coverage. Provide each steel reinforcing member which is to be post-tensioned with a non-migrating slipper coating applied prior to the addition of concrete to ensure uniformity of stress throughout the length of such member.

d. Strength Requirement

As an exception to the requirements of ASTM C1089, allow poles to cure naturally to achieve a 28-day compressive strength of 48.23 MPa 7000 psi.

Do not allow poles to be subjected to severe temperature changes during the curing period.

SECTION 26 56 13.00 40 Page 16

c. Ground Rods

NOTE: Determine the size, type, and number of ground rods to be used, based on local conditions, earth resistively data, and on the size and type of the electrical installation. Copper clad steel rods will be specified for normal conditions. Zinc coated steel or stainless steel rods will be used where low soil resistivities are encountered and galvanic corrosion may occur between adjacent underground metallic masses and the copper clad rods. Stainless steel rods have a longer life than zinc coated steel, but use of stainless steel should be justified based on the higher cost. Rods 15.9 mm 5/8 inch in diameter and2.4 m 8 feet in length are generally acceptable; however in rocky soils specify

19.1 mm 3/4 inch rods. In high Resistivity soils,

SECTION 26 56 13.00 40 Page 22

][ 3.1.5 Standard Foundations

3.1.5.1 Excavation

Restrict excavation in size to that which provides sufficient working space for installation of concrete forms. Should soil conditions at the bottom of the excavation be unsuitable as a foundation, as determined by the Contracting Officer, take the excavation down to firm soil and fill to required grade with concrete or satisfactory soil materials as directed.

Perform excavations in a manner to prevent surface, subsurface, and ground water from flowing into the excavation. Use pumps or other dewatering methods necessary to convey the water away from the excavation work below ground-water level.

[ Depth is as indicated [on the drawings] [in the table above]. Dig holes large enough to permit the proper use of tampers to the full depth of the hole. Place backfill in the hole in 150 mm 6-inch maximum layers and thoroughly tamp. Place surplus earth around the pole in a conical shape and pack tightly to drain water away.

] 3.1.5.2 Formwork

Construct forms of wood, plywood, steel, or other acceptable materials fabricated to conform to the configuration, line, and grade required.

Reinforce formwork to prevent deformation while concrete is being placed and consolidated. Wet or coat formwork with a parting agent before placing concrete.

3.1.5.3 Setting of Anchor Bolts

Set anchor bolts or rods with exposed threaded ends vertically positioned in the concrete [using a template supplied by the pole manufacturer] [in accordance with the lighting standard manufacturer's recommendations.]

3.1.5.4 Concrete Placement

Level and steel trowel concrete bearing surface to a smooth, hard, dense finish surface. After form work is removed, protect the exposed concrete with impervious paper or burlap material and keep wet for the full curing period.

][ 3.1.6 Special Foundations

] 3.1.7 Standard Setting

Install standards, with their bases level so that standards are plumb.

Once the concrete has cured, set the pole on the foundation, level on the foundation bolts, and secure with the holding nuts. Grout the space

SECTION 26 56 13.00 40 Page 23 between the foundation and the pole base. Conform concrete and grout work to Section[ 03 30 00.00 10 CAST-IN-PLACE CONCRETE][ 03 35 00.00 10 CONCRETE FINISHING][ 03 39 00.00 10 CONCRETE CURING]. Provide concrete strength of 21 MPa 3000 psi at 28 days.

3.1.8 Grounding

NOTE: Butt grounds are not be permitted as an option in dry desert areas. See HREF=http://www.wbdg.org/ccb/DOD/UFC/ufc_3_550_01.pdf>UFC 3-550-01, "Exterior Electrical Power Distribution" .

Provide grounding conforming to NFPA 70 , the contract drawings, and the following:

a. Provide soft-drawn, stranded copper grounding conductors.

b. Drive ground rods into the earth so that after the installation is complete, the top of the ground rod is approximately 300 mm 1-foot below finished grade, except in handholes.

[ c. Use butt grounds made of at least 4 m 13-feet of No. 6 bare copper wire stapled to the butts of wood poles in spirals where a ground resistance of 25 ohms or less can be obtained by this method.

][ d. Butt grounds are not allowed.

] 3.1.8.1 Ground Rods and Pole Butt Electrodes

NOTE: Designer is to determine the size, type, and number of ground rods to be used, based on local conditions, earth resistively data, and on the size and type of the electrical installation. Specify copper clad steel rods for normal conditions. Use zinc coated steel or stainless steel rods where low soil resistivities are encountered and galvanic corrosion may occur between adjacent underground metallic masses and the copper clad rods. Stainless steel rods have a longer life than the zinc coated steel; use only if the use of stainless steel is justified based on the higher cost. Rods 15.9 mm 5/8 inch in diameter and 2.4 m 8 feet in length are generally acceptable; however in rocky soils specify

19.1 mm 3/4 inch rods. In high resistively soils, use 3.1 m 10 feet or sectional rods to obtain the required resistance to ground; however where rock is encountered, additional rods, a counterpoise, or ground grid may be necessary.

Measure the resistance to ground using the fall-of-potential method described in IEEE 81 . The maximum resistance of a [driven ground rod] [pole butt electrode] is not to exceed 25 ohms under normally dry conditions. Whenever the required ground resistance is not met, provide additional electrodes [interconnected with grounding conductors] [as indicated], to achieve the specified ground resistance. Provide additional

SECTION 26 56 13.00 40 Page 24 electrodes [up to three, [2.4] [3] m [8] [10]-feet long rods spaced a minimum of 3 m 10-feet apart] [a single extension-type rod, [15.9] [19.1] mm [ 5/8] [3/4]-inch] in diameter, up to 9.1 m 30-feet long, [driven perpendicular to grade] [coupled and driven with the first rod]. In high ground resistance, UL listed chemically charged ground rods may be used.

If the resultant resistance exceeds 25 ohms measured not less than 48 hours after rainfall, notify the Contracting Officer immediately. Fusion weld connections below grade. Fusion weld or use UL 467 approved connectors for above grade connections.

3.1.8.2 Items to be Grounded

Ground all ground conductors, metallic conduits, junction boxes, and noncurrent-carrying metallic parts of equipment. Make connections above grade with solderless connectors, and fusion weld those below grade.

3.1.8.3 Lighting Pole

Provide one ground rod at each pole. Connect bases of metal or concrete lighting poles to ground rods by means of No. 8 AWG bare copper wire.

Ground the lighting fixture brackets on wood and concrete poles to a No. 6 AWG bare copper grounding conductor connected to the ground rod.

3.1.8.4 Handhole

In each handhole, at a convenient point close to the wall, drive a ground rod into the earth before the floor is poured. Make provision for approximately 100 mm 4 inches of the ground rod to extend above the floor after pouring. When precast concrete units are used, the top of the ground rod may be below the floor, and bring a No. 1/0 AWG copper ground conductor inside through a watertight sleeve in the wall. Make connection to ground rods by means of bolted-clamp terminals or by an approved fusion-welding process. Neatly and firmly attach ground wires to handhole walls, holding the amount of exposed bare wire to a minimum.

3.1.8.5 Metal Cable Boxes

Connect metal cable boxes for direct-burial cable to adjacent ground rods by wires with current-carrying capacities of at least 20 percent of the spliced phase conductors, but not less than No. 6 AWG.

3.2 FIELD QUALITY CONTROL

3.2.1 Ground Resistance Measurements

Measure the resistance to ground by the fall-of-potential method described in IEEE 81 .

3.3 CLOSEOUT ACTIVITIES

3.3.1 Record Drawings

Maintain and keep up to date, a separate set of drawings, elementary diagrams and wiring diagrams of the lighting to be used for "record" drawings, showing all changes and additions to the lighting system. In addition to being complete and accurate, keep this set of drawings separate and do not use for installation purposes. Upon completion of the record
