About this file
This amendment modifies solicitation number W9127N-22-R-0020 for the Mount St. Helens Spirit Lake Tunnel Intake project issued by the Department of the Army Corps of Engineers Engineering District Portland. The amendment updates specification section 01 10 10.00 25 3.4(a) regarding allowable lake stage levels during construction activities. It also replaces drawing S-701 with the attached revised drawing. The multiphase project focuses on addressing Spirit Lake's drainage issues and includes replacing the aging intake gate. Specific work includes constructing a temporary access road, a lake-side barge loading facility, mechanical dredging from barges or floating platforms, building and working behind a cofferdam, and replacing the inlet gate and slide gate with hydraulic steel structures and concrete repairs to the headwall.
