About this file

This document is Appendix A for a U.S. Army Corps of Engineers solicitation to procure and replace a log boom at North Hartland Lake in Vermont. The appendix contains maps, technical drawings, and informational photos detailing the log boom replacement project. Key technical specifications include replacing approximately 2,300 feet of one-inch diameter wire rope, 30 log boom chains, 12 rope clamps, and two thimbles. The project involves removing existing wire rope and hardware, disposing of six deteriorated logs on land, moving six logs from the lake, and installing 11 government-furnished log booms ranging from 10 to 19 feet in length.

The procurement is set aside for small businesses with NAICS code 238990 and a small business size standard of $19 million. The construction project is valued between $100,000 and $250,000. All vendors must have an active SAM.gov registration at the time of submission, with non-registered vendors being rejected as non-responsive. The appendix provides detailed visual documentation of the current log boom infrastructure, including anchor points, chain connections, and log positioning requirements to guide potential contractors in understanding the scope and technical requirements of the replacement project.
