The U.S. Army Corps of Engineers - St. Paul District seeks a contractor to perform repairs on the Lock & Dam 2 concrete crossover joints. Lock & Dam 2 is located at 1350 Dam Road, Hastings, MN 55033. The lock chamber is currently dewatered for repairs and maintenance, and will remain dewatered for the duration of the contracted work to provide safe access to the joints,

The work shall include (but not be limited to) supplying payment and performance bonds, preparing an approved Accident Prevention Plan, cleaning and preparing the joints, and properly install polyurethane (PU) grout(s) through methods of pressure injection or an acceptable alternative method proposed by the contractor. The original copper water stops may have been compromised and soil movement through this joint appears to be occurring. A total of two (2), expansion joints (EJ) need repair and are located at the bottom of the dewatered lock. The crossover is a 9’ x 9’ concrete box culvert and has a total of 36 linear feet per joint for repair. However, only 9 liner feet per joint is exposed from the top. The Contractor shall be responsible for all equipment, materials, labor and other items and services required to accomplish the work.

All work shall be in conformance with the Corps of Engineers Safety and Health Requirements Manual EM 385-1-1 (latest edition). The contractor shall be responsible for clean-up of all work that is required in this contract. The contractor shall repair, at no expense to the Government, damage to the lock, and other existing facilities resulting from failure to comply with the requirements of this contract or failure to exercise reasonable care in performing the work. Clean adjacent surfaces soiled by the PU grout(s) installation. Pick up all old joint sealant, filler and debris from contractor’s operations and dispose of off-site properly.

PREPARATION OF EXISTING JOINTS
Clean joint surfaces of residual sealant, fillers, and other contaminates capable of affecting sealant bond to joint surface by wheel grinder, wire brush, and joint cleaner, pressure washer, or other methods recommended by the sealant manufacturer. The exterior perimeter of the two (2) vertical and bottom horizontal joints within each EJ shall be injected with the hydrophobic polyurethane grout. Then the interior joint section will be injected with hydrophilic polyurethane grout. Prior to the installation of the expansive rope, the contractor shall ensure the joint surfaces are clean of debris and in a self-saturated dry (SSD) condition. No standing water shall be present within joint. The debris shall be removed from site and not allowed in the waterway.

INSTALLATION OF EXPANSIVE ROPE

The Contractor shall complete the installation of expansive rope in accordance with the manufacturer’s instructions or as stated herein, across the top 9 linear feet of each joint (18 linear feet total). The rope and urethane resin shall cover the joint completely up to the depth of the joint sealant. Ensure a minimum 1/2” from the top surface within the joint is free of expansive form and or other debris that may cause debonding during the joint sealant installation.

INSTALLATION OF JOINT SEALANT
Install joint sealants in accordance with ASTM C 1193, manufacturer's instructions, across the top 9 linear feet of each joint (18 linear feet total). Maintain finished joints free of embedded matter, ridges and sags during the curing period.

This project will require completion of work prior to March 1, 2024, as work must be performed while the lock is dewatered for maintenance.
