About this file
This is a Performance Work Statement (PWS) for debris removal services at the Hopkinton Dam Log Boom and Trash Rack Area in Hopkinton, New Hampshire, issued by the U.S. Army Corps of Engineers.
The PWS requires contractors to remove debris accumulated at two primary service areas: the Log Boom area and the Trash Rack area at Hopkinton Dam. Contractors must conduct a site visit prior to submitting quotes to assess the quantity and type of debris present, as the volume varies seasonally. The work involves clearing debris from the Log Boom (shown with a red containment boom in the reference photos) and the Trash Rack (located at the dam structure). The river bottom in the work area is approximately 16-18 feet deep, consisting of a partial concrete bib and rock river bottom, with debris distributed throughout the entire water column between concrete wing walls. Access to the work areas is available via NH Route 127 (Maple Street) and designated access roads. Critical protection requirements include safeguarding the Log Boom's concrete trough with oak planking that allows vehicular crossing, as well as the debris screens (measuring 24" x 130" with ¾" mesh) and their attachment hardware. Contractors must exercise caution to prevent damage to the log boom infrastructure, wing walls, and related equipment during debris removal operations. The document provides eight informational photographs and one map depicting debris conditions as of April 8, 2026, and identifying approximate service area locations and access routes.
