Wire Mesh 710.02(a)

Construction Requirements

619.03 Fences and Gates.

(a) General. Remove all existing fencing (approximately 4650 lineal feet) according to Special

Contract Requirement Section 203.

Grubbing is not required, except where short and abrupt changes in the ground contour require removal of stumps to properly grade the fence line.

Install new fence in the footprint of the removed fence to the extent possible with minor revisions as approved by the COR.

Schedule the fence installation, provide temporary fence, or other adequate means to prevent livestock/game from entering the project limits. Schedule removal and installation so that no access is provided to prohibited area at any time.

(b) Metal post fence and gates.

Revised Forest Service Supplementary Specs FP-14 for the Mauldin Elk Fence Solicitation, 12751218Q0011 dated

(1) Posts. Space line posts at not more than 12-foot intervals and not less than 8–foot intervals. Measure the post spacing interval horizontally. Set posts vertically.

Drive or auger line posts in the ground to meet the embedment required. Ensure post embedment results in a firm stable installation.

Where solid rock is encountered without overburden, drill line post holes at least 14 inches

(350 millimeters) deep. Drill end, corner, gate, and pull posts at least 20 inches

(500 millimeters) deep in the solid rock. Make the hole width or diameter at least 1 inch

(25 millimeters) greater than the post width or diameter. Cut the post to the required length before installation or drill the hole deep enough to set the post at the required height. Set and plumb the post and fill the hole with grout. Thoroughly work the neat hydraulic cement grout into the hole to eliminate voids. Crown the grout to drain water away from the post.

Where solid rock is covered with soil or loose rock overburden, set posts to the plan depth or to the minimum depth into the solid rock as specified above, whichever is less. When solid rock is encountered before the plan depth, grout the portion of the post in solid rock and backfill the post hole from the solid rock to the top of the ground with concrete.

Provide end, gate, corner, and pull posts with adjacent brace posts as shown in the plans.

A change in the fence alignment of 20 degrees or more is considered a corner unless otherwise directed by the COR..

(2) H- Brace, corner, stream crossing and Gate posts. Embed posts in concrete to the depths shown to ensure plumb secure installation.

(3) Fence welded wire panels/mesh. Place the welded wire fence panels or mesh to the dimensions shown and approximately 5 inch above the ground on a straight line between posts. Excavate high points of the ground to maintain grade. Fill in depressions to ensure

5 inches is maintained to the extent possible.

Fasten panels/mesh to line posts using 12.5 gauge clips, or other approved method. Fasten the top and bottom edge of the fabric with tie wires or hog rings to the top rail or tension wires as applicable.

Join panels in such a manner to ensure adequate overlap and consistent pattern.

(4) Gates. Provide and install gate as per subsection 103.3

Hinge each single gate to prevent removal of the gate without tools. Set the gate in an approximately horizontal plane. Set the gate so it swings freely inward and outward and fastens securely in its latch holder, or in the case of double gates, in its latch holder and gate stops. Set double gates on their respective hinge pintles to provide a common horizontal plane in which each single gate swings. Set gates to swing open at least 90 degrees in each direction.

(6) Braces. Limit fence runs to no more than 1320 feet between adjacent corner braces, gate braces, or end braces unless approved by the COR. Install line braces at uniform intervals so the distance between any two braces is 1320 feet or less. Construct braces before placing the fence fabric and wires on posts.

(a) Metal braces. Provide corner posts and pull posts with two braces, one each

Revised Forest Service Supplementary Specs FP-14 for the Mauldin Elk Fence Solicitation, 12751218Q0011 dated direction from the post in the main fence line. Provide end posts and gate posts with one brace in the line of the fence. Attach metal braces to the metal end, corner, pull, and gate posts and set in concrete as shown in the plans.

(7) Woven wire/Mesh. Place mesh as shown on the drawings.

Apply tension according to the manufacturer’s recommendations using a mechanical stretcher or other device designed for such use.

(8) Woven wire/Mesh. End the woven wire/ mesh at each end, corner, gate, and pull post.

At line posts, fasten the woven wire to the post at top and bottom and at intermediate points not exceeding 12 inches apart. Securely splice tie wires to the fence on both sides of the post so there are two loops behind the post and one loop in front.

619.04 Grounding Fences. Where an electric line crosses the fence line, ground the fence. Drive an

8-foot (2.4-meter) long, ½-inch (13-millimeter) minimum diameter galvanized or copper coated steel rod into the ground under the fence directly below the point of crossing. Drive the rod vertically until the top is 6 inches (150 millimeters) below the ground surface. Connect the grounding rod to each fence element with a ¼-inch (6-millimeter) diameter solid copper conductor or equivalent. Either braze the connections or fasten with noncorrosive clamps.

Where an electric line runs parallel or nearly parallel to and above the fence, ground the fence at each end or gate post or at intervals not exceeding 1,600 feet (500 meters).

Where vertical penetration of the grounding rod cannot be accomplished, use an equivalent horizontal grounding system.

619.05 Acceptance. Material for fences, gates, cattle guards, and bollards will be evaluated under

Subsections 106.02 and 106.03.

Construction and erection of fences, gates, cattle guards, and bollards will be evaluated under

Subsections 106.02 and 106.04.
