Hamilton Construction Co

Hamilton Construction Co, operating through its US Foundations, LLC division and doing business as Hamilton Construction Alaska CO., is a for-profit infrastructure construction company based in Springfield, Oregon. The company has been registered to receive federal awards since April 2003 and specializes in bridge replacement, construction, and transportation infrastructure projects. Hamilton Construction Co has established itself as a capable contractor for the Federal Highway Administration, demonstrating expertise in complex infrastructure work across multiple western states including Alaska, Montana, Idaho, and Colorado.

Through its prime federal contract awards, Hamilton Construction Co has secured substantial transportation infrastructure projects funded by the Federal Highway Administration. Most notably, the company was awarded a $10.25 million firm fixed price definitive contract in December 2025 for the replacement of the Ghiglione Bridge in Denali National Park, Alaska, with completion scheduled for September 30, 2027. This project encompasses structure construction, grading, drainage, base work, erosion control measures, and demolition of the existing bridge, requiring delivery of 1,400 cubic yards of roadway excavation, 230 cubic yards of structural concrete, 137,000 pounds of steel structures, and 64,000 pounds of reinforcing steel. Additionally, Hamilton Construction Co was awarded a $16.9 million firm fixed price contract in January 2025 for the MT FLAP BOR 2980(1) Sun River Bridge Replacement project in Augusta, Montana, involving construction of a new 3-span, 462-foot long precast-post-tensioned girder bridge with precast concrete deck and approach embankments. Both of these definitive contracts were awarded through full and open competition with no set-aside designations. As a subcontractor, Hamilton Construction Co provided bridge work services to M.A. Deatley Construction, Inc. in May 2022 and pre-construction services to Granite Construction Company in January 2023, demonstrating its capability to support larger prime contractors on federal transportation infrastructure projects.

Hamilton Construction Co's involvement in federal grant programs includes subcontract work supporting the Colorado Department of Transportation. The company provided construction services related to two distinct transportation infrastructure projects awarded in January 2021: the C-470 Noise Wall project located west of Lucent, Colorado, and bridge bearing replacement work on Interstate 70, Interstate 76, and Interstate 270. These grant-funded subcontract awards showcase the company's ability to execute specialized transportation infrastructure improvements beyond bridge construction, including noise mitigation structures and bridge component replacement work on major interstate corridors.

Hamilton Construction Co holds a significant Indefinite Delivery/Indefinite Quantity (IDIQ) Multiple Award Task Order Contract (MATOC) with the Federal Highway Administration, awarded on April 30, 2025, with a ceiling value of $60 million and a performance period extending through April 29, 2028. This multiple award vehicle authorizes the Federal Highway Administration to issue individual task orders for construction and rehabilitation services across Idaho, Montana, and surrounding areas. The underlying contract was evaluated based on sample project work including sub-excavation, grading, drainage improvements, base preparation, paving, pavement milling, curbing, and exposed aggregate sidewalk construction, representative of the types of transportation infrastructure projects anticipated under the MATOC. The contract was modified to comply with Executive Order 14173 requirements, incorporating electronic payment processing clauses per the Transportation Acquisition Regulation. This IDIQ contract positions Hamilton Construction Co to support multiple Federal Highway Administration priorities throughout the contract period while maintaining pricing and delivery mechanisms demonstrated during the competitive award process.
