Bridge Load Rating & Structural Analysis

The contract requires the performance of load rating calculations and structural analysis for existing bridges in accordance with AASHTO standards to ensure compliance with federal and state transportation safety requirements. The work involves evaluating bridge components under various loading conditions, analyzing structural integrity, and determining appropriate weight restrictions based on engineering assessments. Successful bidders must prepare BrR files and complete technical documentation that supports official load posting decisions and the establishment of weight limits for public use. The contract is designated as a subcontract under NAICS code 541330 for engineering services and is issued by the state of Montana with a response deadline of July 9, 2026. All work must be performed to meet the technical and regulatory standards required by transportation authorities and must result in accurate, defensible documentation that can be reviewed by state and federal agencies. Although specific locations for the bridges are not listed, performance will occur across Montana's infrastructure network and must align with the state’s transportation priorities and safety mandates.
