Starved Rock Lock and Dam - Upper Guidewall Repair

The primary work taskings of this project consist of concrete repairs to the vertical face on the chamber side of the upstream guidewall at Starved Rock Lock and Dam on the Illinois Waterway in the Rock Island District. Work includes, concrete demolition incorporating specialized removal such as wiresawing, vertical concrete resurfacing incorporating precast panels, and removal and reinstallation of the traveling kevel rail system. Contract options may include horizontal resurfacing, and vertical concrete resurfacing around the bullnose are of the guidewall. The contract will be a base bid plus options, and the work will be performed during the summer months of 2018, during on-going navigation restriction through Starved Rock Lock and Dam. The use of a floating marine plant and crane will be necessary to work on the guidewall, with restricted working schedules and construction operations to allow navigation through the lock during non-construction hours. Access to land will be extremely limited within the work area.
