Clearing and grading shall be performed to construct the fence to the required
alignment and to provide a reasonably smooth ground profile at the fence line.
The contractor shall perform 607 Fenceline Seeding and Mulching according to Item 659 Seeding and
Mulching on all areas
disturbed by the clearing and grading for the fence within 8 months of the
activity. The Department will deduct the
area paid for under Item 607 Fenceline Seedng and Mulching from Item 659 Seeding and Mulching quantities as
described in the plan, if applicable.
During the curing period of the concrete encasement, the brace end,
corner, gate, and pull or intermediate anchor posts shall be secured in final
position. Do not require forms for post
encasement.
For Type 47 and Type CLT fence, the maximum
spacing between intermediate anchor post assemblies, or between end post
assemblies and intermediate anchor post assemblies, are 660 feet (200 m).
At points of horizontal deflection, the fence shall be constructed as
follows:
1.
Type 47 Fence. If the fence changes alignment by more than 1
degree, but not more than 4 degrees, either steel line posts encased in
concrete, or wood posts without encasement, shall be installed at all
horizontal deflection points. If the
change in alignment is more than 4 degrees and less than 30 degrees, an
intermediate anchor post assembly shall be installed at the deflection
point. If the change in alignment is 30
degrees or more, a corner post assembly shall be installed at the deflection
point.
2.
Type CLT Fence. If the fence
changes alignment by more than 1 degree, but not more than 4 degrees, line
posts encased in concrete shall be installed at all horizontal deflection
points. If the change in alignment
exceeds 5 degrees, a post brace and truss rod in each fence panel adjacent to
the post located shall be installed at the angle point. If the change in alignment exceeds 5 degrees,
the footings for all posts located at deflection points shall be constructed as
specified for end posts.
Line posts shall be set according to the following:
1.
Type 47 Fence. The spacing of line posts is not to exceed 12
foot (3.6 m) intervals. Line posts at
the bottom of dips or depressions in the ground surface are to be anchored in
concrete.
2.
On tangents, line
posts shall be placed so that the fabric, when installed on the side toward the
highway, is 2 feet (0.6 m) from the Right-of-Way line. If adjacent to Right-of-Way lines with less
than 5,740 feet (1750 m) radius (in excess of 1 degree curvature), line posts
shall be constructed on chords so that the fabric, when installed on the side
toward the highway, is not less than 2 feet (0.6 m) or more than 8 feet (2.4 m)
from the Right-of-Way line.
3.
Type CLT Fence. The tops of
driven line posts shall be protected by drive caps or other method to prevent
distortion of the exposed end. Line
posts are to be spaced at no more than 10 foot (3 m) centers, and placed
so that, when the wire is fastened on the side toward the highway, it is 1 foot
(0.3 m) from the Right-of-Way line.
The fabric shall not be erected until after 5 days from the time of
setting the posts, when using regular cement, or until after 3 days, when using
high early strength cement.
Type 47 fabric shall be stretched and fastened
to line posts using galvanized ties. At
a minimum, one tie shall be used for each of the top and bottom horizontal
wires and one tie for each alternate horizontal wire below the top horizontal
wire.
Chain-link fabric shall be fastened to the line posts using clips or
bands spaced approximately 14 inches (0.4 m) apart, and to the top tension wire using bands or tie wires at
approximately 24-inch (0.6 m) intervals or less. Successive rolls of fabric shall be joined by
weaving a single picket into the ends of the rolls to form a continuous mesh.
The Department will measure Fence, Type ___ by the number of feet
(meters), complete in place. The
Department will measure along the top of the fence from outside-to-outside of
end posts, exclusive of gates and other openings.
The Department will count Gate, Type ___ by the number of complete
units of the size and type specified.
1. Distance between line posts.
2. Depth line posts driven.
3. Diameter and depth of concrete used to encase post
placed in dip section, fence not attached to post for minimum 5 day cure, and 3
days for high early.
4. Post for end, corner, gate, pull, and intermediate
anchor assemblies driven to a depth of __________ (If not driven to grade, diameter and
depth drilled for encasement).
5. Fabric clipped to post at top wire, bottom wire, and
alternate wires between.
6. Document location and measure as per 607.09.
7. Document Fenceline Seeding
and Mulching locations and quantities of area seeded. Deduct Fenceline Seeding and Mulching from 659
Seeding and Mulching if applicable
