162-3.1 CLEARING FENCE LINE. All trees, brush, stumps, logs, and
other debris which would interfere with the proper construction of
the fence in the required location shall be removed a minimum
width of 2 feet (61 cm) on each side of the fence centerline
before starting fencing operations. The cost of removing and
disposing of the material shall not constitute a pay item and
shall be considered incidental to fence construction.
162-3.2 INSTALLING POSTS. All posts shall be set in concrete at
the required dimension and depth and at the spacing shown on the
C. I
7/6/94 AC 150/5370-10A CHG 8
plans.
Posts should be spaced not more than 10 feet (3 m) apart
and should be set a minimum of 36 inches (90 cm.) in
concrete footings. If the frost depth is greater than
36 inches (90 cm), the posts should be set accordingly.
The posts holes shall be in proper alignment so that
there is a minimum of 3 inches (75 mm) of concrete on
all sides of the posts.
The concrete shall be thoroughly compacted around the posts by
tamping or vibrating and.shall have a smooth finish slightly
higher than the ground and sloped to drain away from the posts.
All posts shall be set plumb and to the required grade and
alignment. No materials shall be installed on the posts, nor
shall the posts be disturbed in any manner within 7 days after the
individual post footing is completed.
Should rock be encountered at a depth less than the planned
footing depth, a hole 2 inches (50 mm) larger than the greatest
dimension of the posts shall be drilled to a depth of 12 inches
(300 mm). After the posts are set, the remainder of the drilled
hole shall be filled with grout, composed of one part Portland
cement and two parts mortar sand. Any remaining space above the
rock shall be filled with concrete in the manner described above.
In lieu of drilling, the rock may be excavated to the required
footing depth. No extra compensation shall be made for rock
excavation.
162-3.3 INSTALLING TOP RAILS. The top rail shall be continuous
and shall pass through the post tops. The coupling used to join
the top rail lengths shall allow for expansion.
162-3.4 INSTALLING BRACES. Horizontal brace rails, with diagonal
truss rods and turnbuckles, shall be installed at all terminal
posts.
162-3.5 INSTALLING FABRIC. The wire fabric shall be firmly
attached to the posts and braced in the manner shown on the
plans. All wire shall be stretched taut and shall be installed to
the required elevations. The fence shall generally follow the
contour of the ground, with the bottom of the fence fabric no less
than 1 inch (25 mm) or more than 4 inches (100 mm) from the ground
surface. Grading shall be performed where necessary to provide a
neat appearance.
At locations of small natural swales or drainage ditches and where
it is not practical to have the fence conform to the general
contour of the ground surface, longer posts may be used and
5
multiple strands of barbed wire stretched thereon to span the
opening below vertical
of barbed wire shall be 6 inches (150 mm) or less.
openings below the fence may also be spanned with barbed
vire fastened to states.
The Engineer shall specify if tension wire is to bz
installed.
162-3.6 ELECTRICAL :lam; Electrical grounds
constructed [where a power line passes over the fence] [at
r• s. matervals]. [The ground shall be installed
directly bel. . the point of crs _ in The ground
accomplished with a copper clad rod 8 feet (240 cm) long and a
minimum of 5/8 inch (15 mm) in diameter driven vertically until
the top is 6 inches (150 mm) below the ground surface. A No. 6
solid copper conductor shall be clamped to the rod and to ^.
fence in such a manner that each elementof
grounded. Installation of ground rods shall not constitute a pay
item and shall • ' considered incidental to fence constructiox.
The Engineer shall indicate the location of all electrical
grounds on the plans.
162-4.1 Chain -link fence will be measured for payment by the
linear foot (meter). Measurement will be along the top of the
fence from center to center of end posts, excluding the length
occupied by gate openings.
Gates will be measured as complete units.
162-.1 Payment for chain -link fence will be made at the contract
unit price per linear foot (meter).
Payment for driveway or walkway gates will be made at the contract
unit price for each gate.
The price shall be full compensation for furnishing all materials,
and for all preparation, erection, and installation of these
materials, and for all labor equipment, tools, and incidentals

c
: Rural Airports and some metropolitan airports are faced with an ever-growing
problem of deer and other wildlife on runways. Obviously, fencing around the
►, property requires a lot of fence and money! A conventional chain link, 8' high,
I
can be expensive and can be very obtrusive.
nowSolidl.ock offers an alternative. An 8' to 12' deer fence can be
installed for 30% to 50% less than commercial chain link. SoSdLack wildlife
fence is a fabricated net- wire, made of 12.5 ga. Hi -tensile wire. This wire has a
breaking strength of 1350 lbs., with a zinc coating of 1.1 oz. of zinc per square
foot. This exceeds Class 3 coating. It is constructed using solid horizontal and
vertical wires, then a third wire is double wrapped at each intersection of wire to
form a very strong, long lasting, fabric. SOH&Ock was specifically developed
for wildlife and is a proven performer.
SaIltllock is manufactured in rolls up to 660' which requires considerably less
splicing during construction. Several heights up to a full 8' makes it twice as
high as most conventional fabrics.
SOIIdLock's fabrication of hi -tensile wire provides excellent wire memory. Stress
and impact show no visible signs of stretching or sagging. Wire strength also
allows the fence to be constructed using 20' to 25' post centers. Bracing is re-
quired every 1320' centers, again saving money. Generally 10' to 12' high fences
can be constructed of SoUdLock for less than 8' commercial chain link. This
provides sure-fire deer control and added security.
SoUdLock is strong and long lasting, yet it doesn't give the appearance of a
fortress. A SoUdLock fence blends well with its surroundings.
If you are having problems with deer or any other wildlife,
you should consider SoMfWck.
