RECOVERY--Z--THIS IS FOR INFORMATION PURPOSES ONLY-RECOVER-PROJECT NUMBER 009080 - New Gate Roller Chains at Knighville Dam, Huntington, MA

The contract involves the replacement and rebuilding of roller chains on the steel gates at Knightville Dam in Huntington, Massachusetts. These gates, approximately 70 years old, use roller chains for movement, which are operated by stationary wire rope hoists. One chain on gate 3 has fallen off and requires replacement with two new chains, while the remaining five chains need to be rebuilt using existing rollers and links but with new pins featuring retaining ring fasteners instead of riveted pins. Work must proceed on only one gate at a time to ensure the other two remain operational, and any extra chain materials will be stored onsite as spares. This project is solely open to the existing contractor under contract number W912WJ-09-C-0028, Watermark Environmental, Inc., reflecting a recovery and maintenance effort by the U.S. Army Corps of Engineers, New England District. The solicitation was posted in 2010 and falls under NAICS code 238290, which pertains to building equipment contractors. The task specifically aims to maintain the functional integrity of the dam’s gate operations, crucial for water control and safety, highlighting careful coordination to avoid disrupting dam functions during repairs.
