About this opportunity
The Department of the Army Corps of Engineers Engineering District Omaha is seeking contractors to modify stoplog seals at the Garrison Dam Spillway in North Dakota. The project involves removing eight existing stoplogs (fabricated in 2016, weighing approximately 15,400 pounds each) from the spillway, transporting them to a certified fabrication shop, replacing seals and springs, performing welding and fabrication work according to AWS D1.5 standards for fracture-critical members, applying a specific vinyl paint system, and returning the modified stoplogs to their original locations. Contractors must possess AISC certification with fracture critical endorsement and demonstrate past performance on hydraulic steel structure modifications including projects valued over $1 million. The evaluation will be conducted using a best value tradeoff approach with past performance as the most important technical factor, followed by fabricator certification, with total evaluated price approximately equal to the combined technical factors. The original proposal deadline was extended through multiple amendments, with the final due date of August 12, 2025, and a mandatory site visit was conducted on July 9, 2025.
This procurement is designated as a 100% small business set-aside with an estimated construction cost between $1,000,000 and $5,000,000. The contract includes a base requirement for eight stoplog modifications with an option to modify an additional ten stoplogs, utilizing a firm fixed-price structure with performance and payment bonds required. The performance period spans from September 1, 2025, to April 26, 2027, with work commencing within 10 calendar days of notice to proceed and completion required within 600 calendar days. Work restrictions apply between October 31 and April 15 due to winter conditions, and liquidated damages of $543.00 per calendar day will be assessed for delays. All work will be performed at the Garrison Dam facility in Riverdale, North Dakota, with stoplogs transported to the contractor's certified fabrication facility for modifications before being returned to the dam site for final installation and government testing.
