624RIGHT-OF-WAY FENCE

624.1DESCRIPTION—This work is construction of right-of-way fence of the type indicated.

624.2MATERIAL—

28-day compressive strength of 3,000 pounds per square inch.

• Class A Cement Concrete. Section 704

• Mortar. Section 1001.2(e)

• Ground Rod. Acceptable 1-inch by 10-foot copper clad rod with suitable clamps

• Ground Wire. No. 4 AWG solid copper

624.3CONSTRUCTION—As shown on the Standard Drawings and as follows:

ground profile at the fence line, unless otherwise directed. Cut, trim, and remove vegetation, as specified in Section 810, as required for right-of-way fence installation. Excavate or construct compacted embankment a maximum depth of 6 inches and a minimum width of 18 inches, with 2:1 side slopes, unless otherwise directed to obtain the desired elevations. Fill minor ground depressions that are not water courses. Restore areas disturbed by grading operations as specified in Section 105.14. Join new and existing right-of-way fence as indicated or directed. Complete the fence true to line, plumb, taut, rigid, and erected in conformance with established practices for the type specified.

parallel to the fence line. Place corner posts with the major axis parallel to one of the lines of the fence. Drive line posts, except when concrete footings are required. Obtain acceptance for the method of driving and of protecting the post. Remove and replace posts with battered heads, bent, or otherwise damaged posts as directed. Furnish and place longer line posts where indicated to suit field conditions. If rock is encountered, drill a hole with a diameter that is 1/2 inch larger than the post's maximum dimension, at least 12 inches into the rock, and then grout the post in place with mortar.

footings, using Class A Concrete or packaged dry concrete. Concrete footings do not require forming. Finish the footing tops to drain water away from the posts. Do not place the fabric until the concrete has cured for a minimum of 72 hours.

other acceptable methods. Splice fabric using an acceptable method that develops the full fabric strength.

Place fabric on the side of the fence toward the highway unless otherwise indicated or directed. At corner posts and on curves, place the fabric so it pulls against the post. If supplied with both knuckled and barbed selvages, install fabric with the barbed selvage on the fence top edge.

distribution, or secondary lines cross over the right-of-way fence. Drive a 10-foot copper clad rod, a minimum of 1 inch in diameter, vertically until the top is approximately 6 inches below the ground elevation. Bronze clamp a No. 4 AWG solid-copper conductor to the rod and to the fence so each fence element is grounded.

624.4MEASUREMENT AND PAYMENT—

Excavation and embankment within the specified depth of 6 inches is incidental to this work. If the Representative directs additional excavation and/or embankment beyond the 6 -inch depth indicated, the Department will pay for additional quantities as Class 2 Excavation.
