| Description | Project Information: The project shall include sealing and repairing joints and cracks in the roller compacted concrete spillway, constructing concrete piers, filling voids, and replacing damaged concrete lining. The Contractor will be required to clean the joints and cracks one up to one inch wide, and seal them with silicone sealant. Joints wider than 1 inch shall be grouted. Concrete piers will be used to stabilize the concrete pavement on the upstream side of Barker Dam North and Addicks Dam North spillways. Reinforced concrete will be constructed to replace damaged concrete lining location. Stabilize the upstream side slope concrete lining with the concrete piers before sealing or grouting the longitudinal cracks and joints at Barker Dam North spillway. The project will contain options which the Government may exercise at the time of award. The emergency spillways consist of earthen embankments capped with 8 inch thick roller compacted concrete on the downstream slope, the crown, and partially on the upstream slope. This concrete has no reinforcement, control joints or expansion joints. In the past, repairs have been performed to the concrete with reinforce concrete patches, and cracks and joints have been sealed with asphalt and silicon sealants. Option 1 Addicks Dam North Spillway -Stabilize the upstream side slope concrete lining with the concrete piers before sealing or grouting the longitudinal cracks and joints at Barker Dam North spillway. An additional 30 calendars days will be added to the completion time for this Option. Option 2 Concrete Piers at Barker Dam North Spillway - Where grout and sealant will be in contact, the grout is to be installed first and the silicon is to be applied after the grout has cured based on the manufacturer's recommendations. An additional 84 calendar days will be added to the completion time for this Option. | ||||||
