A. Description of Work Culvert Replacements are s located on FSR 4 Mulky Gap Road, beginning at the intersection with FSR 88 at the Dixon Creek crossing continue north on Mulky Gap Road for about .85 miles to the second culvert where Mulky Creek Crosses FSR 4, Mulky Gap Road. The road is located on the Blue Ridge Ranger

District of the Chattahoochee‐Oconee National Forests in Union County, Georgia. The project is located on Mulky Quad map.

The project removes the existing Dixon Creek, 15 foot long by 42 inch diameter culvert and the existing 36 inch diameter 22 foot long Mulky

Creek Culvert. Both culverts have CCC constructed stone head walls. The stones from the head walls are to be reserved and reused to delaminate the edge of road over the new culvert installations.

The road bed is width at the culverts is 14 feet with 2 feet of shoulder. The approach road has a ditch on upland side of the road that is 1 foot deep. The approach sections are 30 feet long and have a riprap section 24 inches thick topped by 4” compacted in place of GDOT # 4 aggregate. Any of the salvaged headwall stone that is not used in the rebuilding of the new culvert headwalls, if two feet minimum diameter boulders shall be placed on the edges of the travel way to act as curbing on the culverts. The rest may left stockpiled on site for future use by the Forest Service

The replacement culvert at Mulky Creek is a Contech

Aluminum Structural Plate open Box Culvert No. 43, R3 with HG/CG =2/2 or approved equivalent. Culvert spans

19’ 6” and rises 6’ 1” and a length of 22.5 feet. It has an opening of 97.1 ft. sq. with min. cover of 1.4 ft. and max.

cover of 5.0 feet. The loading is HL‐93. The head wall shall be reinforced concrete rather than the standard aluminum because of the need to replicate the masonry headwall on the new culvert. The concrete headwall measures approximately 22’ 3‐3/4” long and 9’‐1” high with two sloping wing walls 10 feet long.

The replacement culvert at Dixon Creek is a Contech Aluminum Structural Plate open Box Culvert No. 28, R3 with HG/CG =2/2 or approved equivalent. Culvert spans 14’‐10” and rises 4’‐10” and a length of 22.5 feet. It has an opening of 63.2 ft. sq. with min. cover of 1.4 ft. and max. cover of 5.0 feet. The loading is

HL‐93. The head wall shall be reinforced concrete rather than the standard aluminum because of the need to replicate the masonry headwall on the new culvert. The concrete headwall measures approximately 18’ 1‐ ¾” long and 9’‐1” high with two sloping wing walls 10 feet long

The Contractors shall provide shop drawings for the headwall and footing design with the Forest Service reviewing and approving the shop drawings before construction of the headwalls begin.

Limited clearing is required at that site. Only those trees which must be removed to adjust the alignment of the new culvert and road widening are expected to be removed. The timber will be marked by the Government prior to removal. The timber will be topped, limbed, cut to length and decked in the dispersed campsite adjacent to the worksite. The tops and limbs will be used as brush barriers to protect the work site from sediment transport.
