607.4CONSTRUCTION

607.

4.1General

1 Control livestock and unauthorized vehicle traffic in accordance with Section 107, Legal Relations and Responsibility to the Public. Clear and grub in accordance with Section 201, Clearing and Grubbing, as necessary to construct fence to the required grade and alignment. 2 Remove fence in accordance with Subsection 202.4.7, Removal of Fence, Snow Fence, and Signs. 3 Place fence 12 in [300 mm] inside the right-of-way lines except where topography prevents construction. When required at breaks in fencing or intersections with existing fences, make appropriate adjustments in post spacing to meet the requirements for the type of fence specified. 4 When imbedding posts, braces, or anchors in concrete, install temporary guys or braces as required to hold the posts in proper position until the concrete sets. Use class B concrete in accordance with Subsection 513.4.4, Mix Design. The engineer may approve a local commercial mix. Do not install materials on posts set in concrete or place stress on guys or bracing until at least seven calendar days after placing concrete. 607.

4.2Wire Fence

607. 4.2.1 Posts 1 For fences with wooden or plastic posts, add metal posts between regular posts at intervals no greater than 500 ft [150 m]. Install one metal post in any length of fence with over 200 ft [60 m] between openings. Set posts firmly and plumb. Remove and replace damaged posts. 607.4. 2.1.1 Wooden Posts 1 Drive or tamp posts. If posts are driven, orient the small end of the post in the ground. Orient tamped posts with large (butt) end in the ground. 607. 4.2.1.2 Plastic Fence Posts 1 Before starting, give the engineer two copies of the manufacturer’s recommendations for installation. Set recycled plastic fence posts by digging, auguring, or driving. Instead of staples and nails, use laydown post clips and predrilled 3/16 inch [5 mm] pilot holes to attach wire fence.

Fences SECTION 607 607.4.2.2 End Panels and Brace Panels 1 Place end posts, corner posts and brace posts with the large end (butt) in the ground. Notch posts to provide a flat bearing surface for cross braces. 2 Use cross braces as specified for the type of panel used and nail to each post with at least three 40d spikes. Bevel diagonal cross braces to obtain adequate bearing against the brace posts. 3 Use type I, II, or III end panels. When conditions prevent installing the deadman required for type I, use a type II or III. End panels placed in a corner installation may share a common end post. Install end panels at each termination of a fence run, change in direction, gate location, and other locations specified by the engineer. 4 When fencing around curves, place a brace panel at the beginning, end, and center of the curve. Depending on the curves radius and length, place additional brace panels at locations along the curve as specified by the engineer. 607. 4.2.3 Wire Installation 1 Attach wire to posts as follows:

ngent Sections. Place on the landowner’s side of the post.

2 If a strand of wire touches the ground, tie it to the next higher wire, or change wire spacing with the engineer’s approval. Firmly attach wire or fencing to posts and braces as specified. Stretch wire taut and install at the required elevations. 607.4.

2.4Stays

1 Use wire stays for barbed wire fence. Place them at midspan between posts and extend 2 in [50 mm] below the bottom wire. For woven wire fence, place wire stays at midspan between posts and extend from the top barbed wire to 6 in [150 mm] below the top of the woven wire as specified. 2 When specified, use wood stays meeting requirements for gate sticks. Space equally and place with the bottom touching the ground. Staple each wire to the stay. 607. 4.2.5 Gates 607. 4.2.5.1 General 1 Provide gate chains for gates wider than 4.5 ft [1.4 m] on right-of-way fence along access control roadways. The department will provide padlocks required for locked gates.

Fences SECTION 607

607.4.2.5.2 Wire Gates

1 Provide wire gates at approaches, cattle guards, and at least one wing fence on each side of the roadway at structure locations and other locations specified or determined by the engineer. When the wing fence is 50 ft [15 m] long or longer, the engineer may require an additional brace or end panel to support the gate.

2 Use the same barbed wire number and spacing as specified for the fence. Use a 6- barbed wire gate with a combination woven and barbed wire fence. For gate hinges and gate supports, use a double loop of 9-gage, galvanized, smooth, twisted wire.

3 Install a gate tightener on all gates. The engineer may approve the use of tighteners other than those specified. Construct tighteners for metal posts the same way and of the same material as for wooden posts.

4 Provide wire gates in accordance with Table 607.4.2-1, Length of Wire Gates.

Table 607.4.2-1 Length of Wire Gates Location Length ft [m] Gate Sticks (equally spaced) Approaches 16.5 [5.0] 4 Gates used by large farm and ranch machinery 20 or 24 [6.0 or 7.2] (as specified)

Separation structures and wing fences 12.0 [3.6] 3 Pedestrian access 4.5 [1.4] 2

607.4.2.5.3 Rail Gates

1 Provide rail gates in 24-inch [600 mm] increments. For double installations provide two gates of equal length. Provide vertical stays in accordance with Table 607.4.2-2, Rail Gate Vertical Stay Requirements.

Table 607.4.2-2 Rail Gate Vertical Stay Requirements Gate Length Ft [m] Vertical Stays (equally spaced) 6, 8, and 10 [1.8, 2.4 , and 3.0] 1 pair 12 and 14 [3.6 and 4.2 2 pair 16 [4.8] 3 pair

Fences SECTION 607 2 Paint rail gates using either system in accordance with Subsection 501.4.1.24, Painting. Apply all coats in the shop or dip paint as per the manufacturer’s recommendations for color and process. 607. 4.2.6 Deadman Installation 1 Install a deadman at each specified location to adequately support the fence and in accordance with the deadman details associated with a type I end panel. Use one of the following:

in [600 mm].

607. 4.2.7 Floodgates 1 Fasten floodgates so that flood debris will rip out the floodgate rather than the main fence. 607.

4.3Wing Fence

1 Install wing fences in accordance with the applicable portions of Subsection 607.4.2, Wire Fence, and at structures with equivalent diameter of at least 72 in [1800 mm], including stockpasses, box culverts, bridges, and other locations, as specified or directed by the engineer. 2 Tie wing fences to the structure with at least four strands of barbed wire extending from the end panel corners to four eye bolts set in the wingwalls, slope paving, or pipe ends. If the engineer determines the fence can be anchored to the structure to maintain integrity, the engineer may elect to eliminate an end panel or substitute a brace panel for an end panel. The engineer may eliminate the requirement to tie the end or brace panel to the structure if it can be butted tight against the structure to prevent animal passage and the end or brace panel is stable. 3 When attaching or abutting the wing fence to the structure is not possible, extend wing fences up, over , and back down the other side of the structure to prevent passage of game and livestock. 4 Construct a detachable fence section across the opening of the structure between wing fences for controlled access highways, at other specified locations, or as determined by the engineer, unless the structure requires continuous access as a stockpass.

Fences SECTION 607

607.4.4 Temporary Fence

1 If placing fence will interfere with construction, place temporary fence. Use the temporary fence type and configuration specified, and leave it in place at the completion of the contract. Temporary fence placed for contractor convenience will be at no additional cost to the department.

2 Install temporary fence in accordance with the applicable portions of Subsection 607.4.2, Wire Fence. Standard brace panels may be used in lieu of end panels. The department does not require gate tighteners for temporary fence wire gates.

607.4.5 Resetting Fence

1 Salvage material, including hardware, posts, brace panels and gates; if insufficient to complete the fence, provide additional new materials at no additional cost to the department.

2 When specified, reset gates by removing, salvaging, and reusing existing gates and hardware. Provide new materials as required at no additional cost to the department.

607.4.6 Industrial Fence

1 Install industrial fence where, and to the height, specified . Install two end panels connected at right angles for each corner installation, two brace panels connected in line for each brace installation, and one end panel for each end installation.

607.4.7 Wire Acceptance

1 For wire products used not meeting the specification requirements for the type of wire specified, the engineer will do one of the following:
