B. Topsoil: Strip the top 4 inches of surface soil from embankment slopes, excavation areas and borrow area and store in designated stockpile areas.

C. Utilities: Before starting excavation, the Contractor shall establish the location and extent of underground utilities (1-800-424-5555) in the work area. Protect utility services uncovered by excavation. Notify the Contracting Officer immediately if utilities are damaged. Damage to utilities shall be repaired at the Contractor's expense.

D. Dewatering: Keep the excavation dewatered so that installation of culverts can be carried on under dewatered conditions. Dispose of excess water by using natural drainageways near the site to the extent of their natural capacity, when no erosion or other damage will occur.

3.2 INSTALLATION

A. Excavation:

1. General: New culverts are to be installed as staked in the field.

Under-excavate the pipe exterior grade to provide a bedding zone (see details on sheets 15 & 16). Do not excavate below the bedding zone unless muck or unsuitable foundation material must be removed.

2. Corrugated Polyethylene Pipe Trench Width (Excavator): When trenches are excavated with an excavator minimum trench width shall be according to ASTM D2321, See drawing 15, and 16, or the excavator bucket width, whichever is wider. Trench width must be of sufficient width to allow use of the type of compaction equipment onsite.

3. Pipe Trench Width SEE DRAWINGS 15 AND 16 FOR TRENCH WIDTH TABLES

4. Borrow areas: Grade borrow areas to drain. Side slopes of borrow areas shall be 2:1 or flatter.

B. Bedding:

1. Culvert bedding: Bedding is the portion of the backfill envelope that is placed directly on the foundation; refer to the drawings. Bedding should be sufficient to provide uniform firm support for the pipe and maintain pipe grade; minimum bedding depth is 4 inches (see details on sheets 15 & 16). If a pipe has a bell-and-spigot joint where the bell is significantly larger than the pipe, the manufacturer may require use of “bell holes” in the installation. Bell holes are depressions in the bedding designed to accommodate the connection so that a stress point does not occur.

C. Backfilling:

1. Culvert haunch: Refer to the drawings for location of the haunch area. The backfill should be installed in 6 inch maximum layers, or lifts, uniformly on each side of the pipe. The backfill shall be shoveled under the pipe, taking care to fill voids. Each haunch area lift of backfill shall be mechanically compacted with two complete passes across the entire surface of the lift. Compaction should be conducted in such a way that the pipe alignment is not disturbed. If pipe alignment is disturbed it must be corrected before compaction continues. Backfill construction should continue up to the pipe springline to complete the haunch area. (see drawings 14, and 15 for specific details)

REVIE

SIO

N 1

6/2

February 9, 2015 Page 3 of 3

2. Initial Backfill: Refer to the drawings for location of the initial backfill. The area of the initial backfill envelope extends from the pipe springline to a minimum of 6 inches above the pipe crown. It should be placed in 6 inch maximum lifts and mechanically compacted to the same density of the adjacent undisturbed road embankment.(see drawings 14 and 15 for specific details)

3. Final backfill: Final backfill extends from the initial backfill to the top of the trench. Refer to the drawings for location of the final backfill. Culvert cover shall be a minimum of 1 foot and construction equipment or vehicles shall not pass over the pipe until this cover is attained.

A. General: Steel posts shall not be used for end-panel, corner-panel, gate-panel, or stress-panel posts. Set wood posts in dug or drilled holes. Drive steel posts. Posts shall be installed plumb, to the designated depth, and the lateral alignment shall be within plus or minus 1/2 inch. Post spacing shall be within 6 inches, but only when ground conditions prevent exact spacing. When treated members must be bored or cut during construction, thoroughly swab untreated surfaces with approved preservative. Avoid breathing sawdust and direct contact of preservative on the skin during field cutting and swabbing. Refer to the preservative manufacturer's required warnings for handling treated members.

B. Ratio of Wood to Steel Line Posts: Line posts shall be all steel.

C. Wood Posts: The Contractor shall dig or drill holes for setting wood posts to the designated depth.

Dug or drilled holes shall provide adequate open space around the post so that backfill can be tamped the full depth around the post. Backfill gradually and uniformly with soil around each post; compact backfill firmly from the bottom of the hole to the ground surface.

D. Steel Posts: Drive into the ground to the depth shown on the drawings or until the anchor plate is slightly below the ground surface. Posts shall be driven plumb. When rock formations prevent driving, remove anchor plate and excavate or drill holes a minimum of 18 inches deep and slightly larger than the diameter of the post. Place posts in the holes and grout the post solidly in position with cement grout or mortar.

E. Corner Panel, End Panel, and Stress Panel Assemblies: Construct as shown on the drawings or as staked in the field. Rock jacks shall not be substituted for these items. Construct stress panels a maximum of 80 rods center-to-center for barbed wire sections. In addition, stress panels are required at points between which wire is to be stretched.

F. Wire: Stretch tightly and staple to wood posts or securely attach to steel posts with standard wire clips. Wire is properly stretched when it is springy to the touch. Terminate wire at each end post, gate post, corner post, or stress panel by wrapping wire around the post two times and tie off by wrapping the incoming wire a minimum of four times. Stretch tightly and staple to wood posts or securely attach to posts with standard manufactured wire clips. Wire clips shall be twisted or otherwise secured off on both sides of the post. Each side of the clip shall be twisted around the wire and back past the clip itself, (more than 360 degrees). Drive staples into wood until the staple comes in contact with the wire against the post, but not so tight as to crimp the wire or prevent free movement of the wire between the post and the staple. Do not drive staples parallel to the grain of the wood.

G. Brace Wires: Shall be double looped with either four plies of 9 gauge or 8 plies of 12 1/2 gauge wires. Number of plies of wire will be counted in the middle of assemblies before twisting. All wires shall be twisted tight with a stick. Leave one end of the stick long enough to fasten behind the horizontal brace to prevent wire from unwinding.

H. Gates: Shall be installed in accordance with the Work Data Sheet and the drawings.

I. Mechanical Gate Closures: Line up the latch with the gate. Adjust latch assembly after installation so that the latch does not bind and the gate hangs properly.

J. Spiking: For spikes larger than 40d, predrilled holes shall be used. The hole diameter shall be 3/4 the diameter of the spike and drilled to a depth no greater than 1/2 the length of the spike.
