It has been changed to W9127N22B0021. THIS IS A PRESOLICITATION NOTICE FOR THE MOUNT SAINT HELENS SEDIMENT RETENTION STRUCTURE (SRS) CREST RAISE The Government intends to procure this requirement on a competitive basis in accordance with the provisions as set forth in FAR Part 15, Contracting by Negitiation. A formal solicitation will follow this announcement on or around June 17, 2022. 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.
