SECTION 32 31 10 Page 23 concrete to eliminate voids. Provide tops of footings that are trowel finished and sloped or domed to shed water away from posts. Maintain vertical alignment of posts in concrete construction until concrete has set.

3.4 CONCRETE STRENGTH

Do not stretch fabric and wires or place rails until the concrete has attained its full design strength and no sooner than 7 calendar days after placement.

3.5 TOP RAILS

Provide top rails that run continuously through post caps. Provide expansion couplings as necessary.

3.6 BRACE ASSEMBLY

Provide bracing assemblies at end and gate posts and at both sides of corner and pull posts, with the horizontal brace located at midheight of the fabric.

Install brace assemblies so posts are plumb when the diagonal rod is under proper tension.

Provide two complete brace assemblies at corner and pull posts.

3.7 TENSION WIRE INSTALLATION

Install tension wire by weaving through the fabric and tying them to each post with not less than 7-gage galvanized wire or by securing the wire to the fabric with 10-gage ties or clips spaced 24 inches on centre. Place tension wire within 4 inches of respective fabric line.

3.8 FABRIC INSTALLATION

Provide fabric in single lengths between stretch bars with bottom barbs placed approximately 1-1/2 inches above the ground line. Pull fabric taut and tied to posts, rails, and tension wire with wire ties and bands.

Ensure fabric remains under tension after the pulling force is released.

3.9 STRETCHER BAR INSTALLATION

Thread stretcher bars through fabric and secure to posts with metal bands spaced 15 inches on center.

3.10 TIE WIRES

Provide tie wires that are U-shaped to the pipe diameters to which attached. Twist ends of tie wires not less than two full turns and bent so as not to present a hazard.

3.11 SUPPORTING ARMS

Install barbed wire supporting arms and barbed wire as indicated on the drawings. Anchor supporting arms to the posts in a manner to prevent easy removal with hand tools. Pull barbed wire taut and attach to the arms with clips or other means that will prevent easy removal.
