Article 1 — Description
Furnish and construct fence of barbed wire or a combination of woven fence fabric and barbed wire, supported on metal or wood posts.
Article 2 — Materials
Furnish materials as shown on the plans and in accordance with this Article.
2.1 Metal Posts and Braces. Furnish steel pipe in accordance with ASTM A53 if used for posts and braces . Use
steel in accordance with ASTM A702 for T -posts. Use only new steel. Do not use rerolled or open- seam material. Furnish galvanized steel sections in accordance with Item 445, “Galvanizing.” Use an approved anticorrosive coating when painting is specified. Spot -coat damaged areas with the same paint color after installat ion of painted posts and braces. Use paint with at least the same anticorrosive properties as the original paint. Use the size, weight, and area of posts, braces, and anchor plates shown on the plans.
2.2 Wood Posts and Braces.
2.2.1 Untreated Wood. Provide cedar or juniper timber.
2.2.2 Treated Wood. Provide pine timber treated in accordance with Item 492, “Timber Preservative and
Treatment.” Remove outer bark and all inner cambium bark on treated posts; occasional strips of bark may remain if not more than 1/2 in. wide or more than 3 in. long. Use sound timber that is free of decay, shakes, splits, or other defects that would weaken the posts or braces or otherwise make them structurally unsuitable for the purposes intended. Knots that are sound, tight, trimmed flush, and not in clusters are allowed, provided they do not exceed 1/3 of the small diameter or the least dimension of the posts and braces. Remove spurs and splinters, cutting the ends square.
2.3 Gates and Gateposts. Furnish materials to the dimensions shown on the plans or as directed.
2.4 Barbed Wire. Furnish barbed wire in accordance with ASTM A121 and as shown on the plans.
2.5 Wire Mesh . Furnish wire mesh fabric in accordance with ASTM A116 and as shown on the plans.
2.6 Miscellaneous. Furnish galvanized bolts, nuts, washers, braces, straps, and suitable devices for holding
barbed wire and wire mesh firmly to metal posts. Use material of good commercial quality and design. Provide galvanized staples at least 1- 1/2 in. long.
Article 3 — Construction
Space fence posts as shown on the plans. Set fence posts plumb and firm at the intervals, depth, and grade shown on the plans. Brace corner and pull posts in two directions. Brace end posts and gateposts in one direction. Install a corner post where the alignment changes 30° or more. Brace the angle post to the adjacent line posts with diagonal tension wires at alignment angles between 15° and 30°. Snub or guy fencing at the critical point of grade depressions and fence sags , where stresses tend to pull posts out of the ground, with a double 9- gauge galvanized wire. Connect the wire to the top horizontal line of 834 the barbed wire or to the top and bottom wire or wire mesh fabric, and to a deadman weighing at least 100 lb. Stretch the fence before guying and snubbing. Install corner, end, pull, or angle post assembly before stretching the wire between posts. Connect existing cross fences to the new fences and corner posts at junctions with existing fences. Fasten to posts using galvanized ties or staples while drawing barbed wire and wire fabric taut, or as shown on the plans. Install pull post assemblies at 500- ft. intervals for steel posts and at 1,000- ft. interval s for wood posts. Metal line posts may be driven provided driving does not damage the posts. Metal corners, ends, pull posts, and braces must be set in concrete footings crowned at the top to shed water. Thoroughly tamp backfill in 4- in. layers. Notch timb er posts as shown on the plans. Unless otherwise directed, T -posts, steel pipe brace posts, steel pipe gate posts, steel pipe post assemblies, and water gap posts must remain in place. Posts removed for the convenience of the Contractor due to brush removal or other issues will be replaced at the Contractor’s expense. Remove brush and trees from fence areas where work is performed. Dispose of debris off the right of way, in conformance with federal, state, and local regulations unless otherwise approved. When approved, chip debris and spread in a thin layer on the right of way . Install water gaps at locations as shown o n the plans .
Article 4 — Measurement
Fencing will be measured by the foot of wire fence, excluding gates and water gaps . Gates will be measured as each gate. Water gaps will be measured by the foot as the distance between fence ends.
Article 5 — Payment
The work performed and materials furnished in accordance with this Item and measured as provided under “Measurement” will be paid for at the unit price bid for “Wire Fence,” “Water Gap,” or “Gate.” This price is full compensation for furnishing, preparing, hauling, and installing fence, water gap, and gate materials; excavation, backfilling, and disposal of surplus material; removing and trimming of brush and tree limbs; and equipment, labor, tools, and incidentals . Unless otherwise shown on the plans, removal of existing fence will not be paid for directly but will be subsidiary to pertinent Items .
