Furnish latches, hinges, stops, keepers, rollers, and other hardware items as required for the operation of the gate. Arrange latches for padlocking so the padlock is accessible from both sides of the gate. Provide stops for holding the gates in the open position.

2.2.3 Posts

2.2.3.1 Metal Posts for Farm Style Fence – Not Apply.

2.2.3.2 Composite Polyester Resin Reinforced Line Posts – Not Apply.

2.2.3.3 Wood Posts

Provide wood posts cut from sound and solid trees free from short or reverse bends in more than one plane. Make tops convex rounded or inclined. Provide posts free of ring shake, season cracks more than 1/4 inch wide, splits in the end, and unsound knots. Provide posts of size and shape indicated. Treat posts in accordance with AWPA U1.

PART 3 EXECUTION

3.1 PREPARATION

3.1.1 Clearing

Clear the area on each side of the fence as indicated in the plans.

3.1.2 Line and Grade

Install fence to the lines and grades indicated. Space line posts to match the existing intervals, use existing pole holes. Set terminal (corner, gate, and pull) posts at abrupt changes in vertical and horizontal alignment. Provide continuous fabric between terminal posts; however, ensure runs between terminal posts do not exceed 500 feet. Repair any damage to galvanized surfaces, including welding, with paint containing zinc dust in accordance with ASTM A780/A780M.

3.1.3 Excavation

No excavation is expected use existing holes for new installation poles. Eliminate surface vegetation along the fence line to the extent necessary to maintain a 2 inch clearance between the bottom of the fabric and finish grade.

3.2 INSTALLATION

3.2.1 Installation

Install fence system per approved installation drawings.

3.2.2 Post

For wood posts (Farm Style Fence), excavate to depth indicated and brace post until backfill is completed. Place backfill in layers of 9 inches or less, moistened to optimum condition, and compacted with hand tampers or other approved method. Set posts plumb and in proper alignment. Drive metal posts or set in concrete as indicated.

3.2.3 Barbed Wire

Install wire on the outside of the post indicated. Pull wire taut to provide a smooth uniform appearance, free from sag. Fasten wire to line posts at approximately 15 inch intervals unless indicated otherwise.

3.2.4 Gate Assembly

For farm style fencing, provide standard metal gate assemblies with frame and fittings necessary for complete installation or wood gates as shown.

3.2.5 Grounding

Ground fences on each side of all gates, at each corner, at the closest approach to each building located within 50 feet of the fence, and where the fence alignment changes more than 15 degrees. Space grounding locations so as not to exceed 650 feet. Bond each gate panel with a flexible bond strap to its gate post.

Use a ground conductor consisting of No. 8 AWG solid copper wire. Use grounding electrodes 3/4 inch by 10 foot long copper-clad steel rod. Drive electrodes into the earth so that the top of the electrode is at least 6 inches below the grade. Where driving is impracticable, bury electrodes a minimum of 12 inches deep and radially from the fence. Ensure the top of the electrode is not less than 2 feet or more than 8 feet from the fence. Clamp ground conductor to the fence and electrodes with bronze grounding clamps to create electrical continuity between fence posts, fence fabric, and ground rods. Test to ensure the maximum total resistance of fence to ground is no greater than 25 ohms.

3.3 CLEAN UP

Remove waste fencing materials and other debris from work site daily.
