About this file
This document provides details for a two-step sealed bid solicitation for construction services. The U.S. Army Corps of Engineers seeks a firm fixed-price contract to modify the spillway at Pipestem Dam on Pipestem Creek near Jamestown, North Dakota. Work will include constructing a stepped roller compacted concrete spillway chute and labyrinth crest control structure, approach walls, stilling basin, and dikes to direct and contain flows. The estimated value is between $100-250 million. Interested offerors must first submit technical proposals which will be evaluated for acceptability before proceeding to step two, when final specifications are issued and sealed price bids are due. The solicitation number is W9128F22B0002 and registration on SAM.gov is required. A site visit is scheduled for May 10th, 2022 with registration in advance.
