and manufacturer\'s written instructions.\]**

**B. abSecurity: Perform work to provide continuous security for
facility. Install new security fencing before removing existing security
fencing. Schedule and fully coordinate work with Contracting Officer.**

**C. abAlignment and Setting of Posts: Set posts plumb, and align posts
in holes 75 mm (3 inches) above bottom of excavation. Space a maximum of
3050 mm (10 feet) center to center, unless otherwise staked or indicated
on the drawings, to the grades indicated. Locate a terminal post at each
change in horizontal or vertical direction of 30 degrees or more.
Protect the portion of posts above ground from concrete splatter. Place
concrete around posts and vibrate or tamp for consolidation. Extend
concrete 50 mm (2 inches) above grade and trowel to a crown to shed
water. Check each post for vertical, horizontal and top alignment, and
hold in position during placement and finishing operations.**

**1. abCure Time: Allow concrete \[and grout\] to cure a minimum of
72 hours before performing other work on posts.**

**D. abTerminal Post Bracing:**

**1. abNo braces are required on fabric 1800 mm high of less where the
top rail is specified. On fabric over 6 feet, braces are required. On
fabric over 12 feet (3700 mm) in height , a center rail is required;
regardless of height, fences installed without a top rail shall have
braces on terminal.**

**2. abSecurely fasten diagonal braces to the terminal post and the
adjacent line post or its footing or a footing of equal size. There
shall be no more than a 50 degree angle between the brace and the
ground. Securely fasten horizontal braces with truss rods to the
adjacent line post and terminal posts.**

**3. abWhen the top rail is used, attach the brace at the halfway point
of the terminal post above grade and, when the top rail is omitted, at
the two-thirds point above grade.**

**E. abTop Rail and Tension Wire:**

**1. abSupport the top rail at each post so that a continuous brace from
end to end of each stretch of fence is formed. Securely fasten the top
rail to the terminal posts and join with sleeves or coupling to allow
for expansion and contraction.**

**2. abWhen the top rail is omitted, stretch a tension wire from end to
end of each stretch of fence at a height that will enable it to be
fastened to the fabric within the top 300 mm (1 foot) of the chain link
fabric. If specified, fasten the bottom tension wire within the bottom
150 mm (6 inch) of fabric. Securely fasten the tension wire to the
terminal posts. The tension wire shall be taut and free of sag.**

**F. abFabric:**

**1. abPlace chain-link fabric on the outside of the area enclosed.**

**2. abPlace the fabric by securing one end, applying sufficient tension
to remove slack before making attachment elsewhere. Tighten the fabric
to provide a smooth uniform appearance free from sag.**

**3. abCut the fabric by untwisting a picket and attach each span
independently at terminal posts. Use stretcher bars with tension bands
at maximum 380 mm (15 inch) intervals or other approved method of
attachment.**

**4. abInstall fence fabric 50 mm (2 inch) above ground level. Measure
clearance at the post with a tolerance of plus or minus 75 mm (plus or
minus 3 inches). Fasten the fabric to the line posts at intervals not
exceeding 380 mm (15 inches). Fasten the fabric to the rail or tension
wire at intervals not exceeding 600 mm (24 inches).**

**5. abJoin rolls of wire fabric by weaving a single picket into the
ends of the rolls to form a continuous mesh.**

**G. abTension or Stretcher Bars: Thread through fabric and secure to
end, corner, pull, or gate posts with tension bands spaced not over
380 mm (15 inches) center to center.**

**H. abTie Wires: Use wire of proper length to secure fabric firmly to
posts and rails. Bend ends of wire to minimize hazard to persons or
clothing.**

**1. abMaximum Spacing: Tie fabric to line posts 300 mm (12 inches)
center to center and to rails and braces 600 mm (24 inches) center to
center.**

**I. abBarbed Wire: Extend end members of gate frames above top member
of gate to match the height of adjacent fence and prepare to receive the
same number of strands as adjacent arms of fence posts. Pull taut to
remove sag, firmly install it in the slots of the extension arms and
secure it. Provide necessary clips for securing wire to extensions.
Attach at maximum intervals of 2400 mm (8 ft).**

**J. abFasteners: Install nuts for tension bands and carriage bolts on
the side of the fence opposite the fabric side. Peen ends of bolts or
score threads to prevent removal of nuts.**

**K. abGrounding: Fences crossed by powerlines of 600 volts or more
shall be grounded at or near the point of crossing and at distances not
exceeding 45 m (150 feet) on each side of the crossing. When the posts
are of nonconducting material, suitable bonding connections shall be
made to the fence mesh and barbed wire strands at each grounding
conductor point. Ground conductor shall consist of No. 8 AWG solid
copper wire. Grounding electrodes shall be 20 mm (3/4 inch) by 3050 mm
(10 foot) long copper-clad steel rod. Electrodes shall be driven into
the earth so that the top of the electrode is at least 152 mm (6 inches)
below grade. Where driving is impracticable, electrodes shall be buried
a minimum of 300 mm (12 inches) deep radially from the fence. The top of
the electrode shall be not less 600 mm (2 feet) or more than 2400 mm (8
feet) from the fence. Ground conductor shall be clamped to the fence and
electrodes with bronze grounding clamps to create electrical continuity
between fence posts, fence fabric, and ground rods. After installation
the total resistance of the fence to ground shall not be greater than 25
ohms.**

**L. abPrivacy Slats: Shall be securely fastened in place.**

**M. abMow Strip: Install a \[rigid PVC\] \[concrete\] mow strip or
