Research Study to Inform Strut-and-Tie Design and Guidance

The Arizona Department of Transportation (ADOT) Master Agreement CTR066839 is a specialized indefinite delivery vehicle focused on engineering and research services, specifically targeting geomatics engineering, project management, and detailed engineering design. The contract encompasses professional services in areas such as front-end engineering design, offshore engineering procurement, and comprehensive engineering procurement services, with a primary focus on developing advanced research methodologies for transportation infrastructure design, particularly bridge construction techniques.

Northern Arizona University (NAU) is the prime contractor for this master agreement, which was initially awarded on July 21, 2023, with a current performance period extending through July 20, 2024. The contract is a state-level master agreement exclusively for Arizona, funded partially by the Federal Highway Administration, with a maximum potential duration of five years. The specific research initiative, "Strut and Tie Modeling Design Guidance" (Project MPD0125-22 SPR-782), aims to develop innovative bridge design approaches that can potentially reduce construction costs and improve structural durability. While specific total contract value was not provided, the agreement includes provisions for deliverables such as technical memoranda, quarterly progress reports, and final research documentation.
