The intent of this project is to increase the length of the existing boat ramp by twenty feet by pushing the existing lower further into the river and pouring a new section in place. The work sequence is assumed to be the following: 1. When water levels are expected to remain below 857.5, the contractor is to place traffic control and break up and remove the grouted riprap that is located at the toe of the ramp. This material may be placed along the upstream side of the ramp. 2. Remove an approximately 2' long portion of the existing bottom slab, for the entire width, in order to allow enough room for a bulldozer blade to push on the remaining existing slab. The demolished concrete is to be hauled off site for disposal. 3. Grade the ramp subbase to match the existing 13.9% ramp grade, for a distance of 20 feet beyond the end of the ramp. Base rock consisting of 6" of Class A Crushed Stone is to be placed on the subbase. 4. Push the existing slab 20' into the river. 5. Pour new ramp slab in place. Tie into the existing slabs by drilling and epoxying in #4 rebar at 24" centers. Keep traffic control up for at least two weeks to allow concrete to cure. 6. Place Class E Revetment along any exposed edges of the ramp. Grout armoring in place.
