F-51 DIVISION 600

Project: AK PRA DENA 10(35), Repave Denali Park Road MP 0.0 to 3.4

636.04 General. At the preconstruction conference, submit a certified cost breakdown for all lump sum items for use in making progress payments and price adjustments.

Submit a list of proposed equipment and material 14 days before installation. Include the manufacturer’s name, size, and identification number of each item. Supplement the list with scale drawings, catalog cuts, and wiring diagrams showing locations and details of equipment and wiring.

The CO will approve the exact locations of the systems.

Remove structures and obstructions according to Section 203. Salvage material acceptable for reuse in the work. Excavate and backfill according to Section 209. Construct concrete according to Section 601.

Where roadways are to remain open to traffic and existing systems will be modified, maintain the existing systems in operation until final connection to the modified circuit to minimize traffic disruptions.

All electrical work shall be performed by licensed electricians or under the direct supervision of a licensed electrician.

Detector drawings do not attempt to show complete details of construction that affect installation. Diagrams are schematic only and do not necessarily show physical arrangement of equipment. Refer to drawings of other trades for additional details which affect work.

Stake the location of the inductive loops, traffic counter, traffic counter cabinet, and camera for approval by the CO prior to beginning installation activities.

Excavate and backfill according to Section 209. Bed the conduit according to Subsection 209.09(c).

636.05 Conduit. Cut conduit so the ends are smooth. Connect conduit sections with couplings to butt the ends of both conduits squarely against each other inside the couplings. Provide a metal expansion and deflection fitting where conduit crosses a structural expansion joint.

636.06 Traffic Signal and Lighting Systems. Furnish systems according to the MUTCD or state adopted supplements to the MUTCD for the state in which the system is located. Design systems to operate according to NEMA.

Design the control unit to energize the lighting circuit upon failure of any component of its circuit.

Furnish a control with an "on" level adjustable between 1 and 5 foot candles (11 and 54 lux).

Operate luminaires with a series circuit distribution system at a potential not exceeding 2400 volts.

Control lights and luminaires by photocell controls. For current less than or equal to 10 amperes, furnish a photocell switch. For current greater than 10 amperes, furnish a photocell switch operating a magnetic relay for switching the lighting circuit.

636.07 Traffic Counter. Locate and install traffic counters as shown in the plans.

The Government will furnish the traffic counter at no cost to the Contractor. Coordinate with the CO to request delivery of a traffic counter for each traffic count station shown in the plans. Begin coordination between 21-28 days before traffic count station work is to begin.

The Government will furnish the modem at no cost to the Contractor. Coordinate with the CO to request delivery of a modem for each traffic count station shown in the plans. Begin coordination between 21-28 days before traffic count station work is to begin.

Mount a fan inside the cabinet and position to direct the majority of airflow over the traffic counter and modem. Mount a fan thermostat at the top of the cabinet and minimize its interference with other cabinet components.

Mount and orient the cabinet to provide an unobstructed, direct line of sight to the roadways that contain count station and vehicle detection equipment when cabinet door is opened. Install traffic counter and communications devices inside cabinet.

Identify and label loop wires inside each pull box in which the loop wires enter. Maintain consistent wiring identification and labeling when entering the cabinet and with connection to the traffic counter. Use water resistant material for wiring identification and labeling. Obtain approval for loop wire assignments at all locations.

Before powering-on equipment within the cabinet provide a copy of the following:

(a) Voltages for power supplies to include, but not limited to electrical meter, batteries, and communications devices, and

636.08 Traffic Loop. Do not install loops when the pavement is wet. Saw cut, wire, and seal for loop wires on the same day. Do not allow vehicular traffic to pass over an open saw cut unless protected.

Wet cut clean, smooth, well-defined, 3/8-inch wide saw cuts at a depth to allow 2 to 2½ inches of cover without damaging the adjacent pavement. Drill 1½-inch diameter loop corners matching the saw cut depth. For the lead-in channel, saw clean, smooth, well-defined, 5/8-inch wide cuts providing a minimum cover of 2 inches. Ensure saw cuts are straight with less than ½-inch error in a 10-foot line. Saw cut the lead-in to the pull box as close as possible to the edge of pavement.

Thoroughly clean the saw cut of foreign material with compressed air and water blasting. Dry the joint with compressed air.

Install the loop wire in one continuous length at the bottom of the cut using a 3/16 - to ¼-inch thick rounded, smooth wood paddle. Install without kinks, curls, or other damage to the wire or its insulation. Replace damaged wires. Hold the loop wire in place with 1-inch lengths of half-inch backer rod spaced at 2-foot intervals.

For the number of loop wire turns, conform to Table 636-1.

Table 636-1 Required Number of Loop Wire Turns

Lead-in Length, feet Number of Turns ≤ 200 3

>200 to 500 4 >500 to 700 5

Where the loop wire crosses a crack or joint, use a plastic sleeve that extends 4 inches (100 millimeters) on each side of the crack or joint. Provide extra loop wire in the sleeve for joint expansion and contraction.

Twist the loop lead-in wires 6 turns per foot (20 turns per meter) from the loop to the pull box.

Do not twist different loop pairs together. Color code the wires of each loop using colored vinyl electrical tape for identification of separate loops inside each pull box as shown in Table 636-2 below. Coil 18 inches (450 millimeters) of lead-in slack in the pull box for each loop.

Before applying sealant, test the loop and lead-in for continuity and resistance by applying a 1000-volt megohmmeter between each end of the loop lead-in and the nearest reliable electrical ground.

If no available ground exists, establish a ground for the measurement. Record the location and megohmmeter readings and submit readings and test equipment data to the CO. Replace the loop if the insulation resistance measured to earth ground is less than 100 megohms at 500 volts DC, the inductance is less than 50 microhenries or more than 800 microhenries, wire resistance is less than

1.75 ohms per 700 feet, or the loop quality (Q) factor is less than 5 at 50 kilohertz.

Installed inductive loops shall have dedicated saw cuts and separate PVC conduits for each sensor lead-in cable from the edge of pavement to the first pull box.

Apply sealant to the saw cuts with the backer rods in place. Apply the sealant in a manner that does not produce air bubbles. Remove excess sealant and finish level with the pavement. Follow the manufacturer’s instructions for sufficient time for the sealant to harden before allowing traffic to cross the loops.

Repeat the resistance and continuity test after sealant is applied. Report the second test for comparison with the first test report.

Preformed inductive loops with 3 to 5 turns of #14 AWG cable with an insulation of XLPE (cross-linked polyethylene) encased in PVC pipe are an acceptable alternative to saw cuts for use in new construction before the pavement is installed. Loop dimensions and spacing based on lane width are shown in Table 636-3. Installation of loops on lanes less than 10 feet wide shall be approved by a Federal Lands traffic engineer prior to installation.
