SOLICITATION NUMBER: W9127N22R0021

NAICS Code: 237990

SIZE STANDARD: $39.5M

SET-ASIDE: Full and Open

DESCRIPTION OF REQUIREMENT

The work will involve the construction of a second crest raise at the SRS. The second crest raise will raise the spillway channel by 10 feet. Along with construction of the second crest raise, a new plunge pool will have to be constructed, and a low flow channel excavated in rock. As part of the project, the contractor will be required to construct water diversion structures so that the work can be performed in the middle of a river. 

BACKGROUND

The SRS was constructed in the late 1980s to store the sediment coming off the avalanche area at Mount Saint Helens so that the sediment does not flow down to the low Cowlitz River. The main objective for the project is to keep the level of protection on the levee systems from Castle Rock to Lexington. A crest raise has already been completed in 2012. This will be the second of three planned crest raises.
