The U.S. Army Corps of Engineers, Rock Island District, Illinois Waterway Project Office (USACE) has the requirement to enter a firm-fixed price contract for the supply and installation of a new Chain Link Security Fence in Peoria, IL. The new security fence shall be completed within 8-weeks of contract award. The contractor (KTR) shall provide all materials, personnel, equipment, and installation to provide a complete and new security fence. USACE will provide no material, equipment, or personnel to assist in the KTR install of the new Security Fence.

1. Attachment 1_FE6 Chain Link Security Fence Details_2 pgs_.pdf

2. Attachment 2_FE6 Chain-Link Security Gate Details_1 pg._.pdf Within one-week of Award and prior to the Contractor ordering materials, USACE will have a kickoff meeting with the Contractor.

515 Linear ft of fence is required, excluding the cantilever fence panel section:

(1) Each double swing gate with (2) Each 120-inch (-0/+ 12”) leaves.

(1) Each placement/start point near but not connected to existing security fence. USACE will connect new fence to existing fence after the Contractor has completed the new fence installation.

(1) Each Fixed Cantilever Panel with the same fabrication materials and methods as the double swing gate leaves, except for the hinge connection type. The panel shall be 156” with 2 each hinge style connections on both supporting posts. The two supporting posts shall be end/corner style posts, not line posts. The supporting post distance from each other will be clarified during the kickoff meeting.

BARBED WIRE:

· Barbed wire must consist of two 12.5 -gage /0.099-inch (2.5 mm) (+0. 005- inch (.127 mm)) twisted line wires with 15-gage /0.080- inch (2 mm) (+0, 005-inch (.127 mm)) round barbs.

· zinc-coated steel

· All barbs must consist of four points and spacing of barbs must be at 5- inch (127 mm) (+1- inch (25.4 mm)) centers.

· Additional details, per attached blueprints.

FENCE FABRIC:

· Selvage on the top and bottom of the fabric shall be twisted with three full twists as shown in the below diagram:

· Minimum to Maximum fence fabric height of 84 inches (7 feet) or (96 inches (8 feet)) when installed. No horizontal overlapping of multiple pieces to achieve the required height; the fabric shall create one uniform piece both horizontally and vertically.

· Fence height including outriggers will be a minimum of 96 inches (8 feet) or (9 feet if 8-foot fence panel fabric is used.).

· Fence fabric must be minimum a minimum thickness of 9-gage wire mesh.

· Installed Fence Fabric shall be within 9” (+/- 1”) from existing grade.

· Fence fabric mesh openings must not be greater than 2”.

· Installed fence fabric and the perpendicular installed concrete at posts shall be in alignment (+/-3/8”) as seen in the blueprints and both shall be within 9” (+/-1”) from existing grade.

· POST GRADE NOTE: USACE will place 7” of gravel (+/-1”) down after the fence has been installed by the Contractor. This will create the required post grade clearance of 2” from the fence and concrete foundation tops as shown in the blueprints; therefore, the finished fence fabric and finished concrete at posts will be in alignment and provide the 2” clearance to gravel and allow 2” of positive drainage away from steel posts; concrete at post exit points should be 9” (+/-1”) above existing grade for USACE gravel fill of 7” (+/-1”). Additionally, this will ensure the required footing depths are achieved against the existing grade. See Diagram in Attachment 1.

· Additional details, per attached blueprints.

POSTS, FRAMES, AND BRACING PIPE:

· Gate posts in concrete shall be schedule 40 or greater.

· All other post shall be LG – 40 or greater.

Bell shape spill out below the forms is okay if it is below the called out deep of the concrete for fence posts.

· Line Posts shall have a minimum concrete footing depth of 42” below existing grade

· End, Corner, Pull, Gate posts and their adjacent line brace posts for bracing off of shall have a 48” minimum concrete footing depth as measured from existing grade.
