607.01 Description. This work consists of furnishing and erecting fence and
gates of the types designated. Construct fence in a manner that provides a rigid, taut fence closely conforming to the surface of the ground. Fence is designated by the following types:
A.Type 47 [47 inch (1195 mm)] woven wire fence fabric, steel line posts, and one strand of barbed wire.
B.Type 47RA [47 inch (1195 mm)] woven wire fence fabric, wood line posts, and no barbed wire.
C.Type CLT [60 inch (1525 mm)] chain -link fence fabric with tension wire. 607.02 483 607.02 Materials.

607.03 Clearing, Grading and Seeding. Perform clearing and grading as
necessary to construct the fe nce to the required alignment, and provide a reasonably smooth ground profile at the fence line. Perform fenceline seeding and mulching according to Item 659 Seeding and Mulching on all areas disturbed by the clearing and grading for the fence within 8 mon ths of the activity. The Department will deduct the area paid for under Item 607 Fenceline Seed ing and Mulching from Item 659 Seeding and Mulching quantities as described in the plan, if applicable.
607.04 Post Assemblies. Securely brace end, corner, gate, and pull or
intermediate anchor posts in position during the curing period of the concrete encasement. The Engineer will not require forms for post encasement. For Type 47 and Type CLT fence, ensure that the maximum spacing between intermediate anchor pos t assemblies, or between end post assemblies and intermediate anchor post assemblies, are 660 feet (200 m).
607.05 Horizontal Deflection. At points of horizontal deflection, construct the
fence as follows:
A.Type 47 Fence. If the fence changes alignment b y more than 1 degree but not more than 4 degrees, install either steel line posts encased in concrete or wood posts without encasement at all horizontal deflection points. If the change in alignment is more than 4 degrees and less than 30 degrees, build an intermediate anchor post assembly at the deflection point. If the change in alignment is 30 degrees or more, build a corner post assembly at the deflection point.
B.Type CLT Fence. If the fence changes alignment by more than 1 degree but not more than 4 degrees, install line posts encased in concrete at all horizontal deflection points. If the change in alignment exceeds 5 degrees, provide a post brace and truss rod in each fence panel adjacent to the post located at the angle point. If the change in alig nment exceeds 5 degrees, construct the footings for all post located at deflection points as specified for end posts.
607.06 Line Posts. Set line posts according to the following:
A.Type 47 Fence. Space line posts at intervals not to exceed 12 feet (3.6 m ). Anchor line posts at the bottom of dips or depressions in the ground surface in concrete. If channels or streams cross the fence line, construct crossings as shown on the plans. On tangents, place line posts so that the fabric, when installed on the sid e toward the highway, is 2 feet (0.6 m) from the Right -of-Way line. If adjacent to 607.07 484 Right -of-Way lines with less than 5740 feet (1750 m) radius (in excess of 1 degree curvature), construct line posts on chords so that the fabric, when installed on the side toward the highway, is not less than 2 feet (0.6 m) or more than 8 feet (2.4 m) from the Right -of-Way line. Locate posts at points of horizontal deflection so that the fence fabric will bear against the post.
B.Type CLT Fence. Protect the tops of driven l ine posts by drive caps or other method to prevent distortion of the exposed end. Space line posts at not more than 10-foot (3 m) centers, and place them so that, when the wire is fastened on the side toward the highway, it is 1 foot (0.3 m) from the Right -of-Way line.
607.07 Fabric. If setting posts in concrete, do not erect the fabric until after 5
days from the time of setting the posts when using regular concrete, or until after 3 days when using concrete with high early strength cement, Stretch and sec urely fasten Type 47 fabric to line posts using galvanized ties. At a minimum, use one tie each for the top and bottom horizontal wires and one tie for each alternate horizontal wire below the top horizontal wire. Fasten chain -link fabric to the line posts using clips or bands spaced approximately 14 inches (0.4 m) apart, and to the top rail or top tension wire using bands or tie wires at approximately 24 inch (0.6 m) intervals or less. Join successive rolls of fabric by weaving a single picket into the en ds of the rolls to form a continuous mesh.
607.08 Barbed Wire. If barbed wire is specified, stretch and fasten it in the
same manner as woven wire fabric.
607.09 Method of Measurement. The Department will measure Fence, Type
___ by the number of feet (meters), complete in place. The Department will measure along the top of the fence from outside to outside of end posts, exclusive of gates and other openings. The Department will count Gate, Type ___ by the number of complete units of the size and type s pecified. The Department will measure Fenceline Seeding and Mulching by the number of feet (meters) of fence. The Department will measure along the top of the fence from outside to outside of end posts, exclusive of gates and other openings.
607.10 Basis o f Payment. The Department will pay for accepted quantities at
the contract prices as follows: Seeding and Mulching shall be paid under Item 607 Seeding and Mulching Item Unit Description 607 Foot (Meter) Fence, Type___ 607 Each Gate, Type___ 607 Foot (Meter) Fenceline Seeding and Mulching
