  • Structures Inspection & Reporting
  • Load Rating

BPA performed routine and fracture critical bridge inspections of Miami-Dade Transit’s elevated guideways and pedestrian bridges through this task work order driven contract. These guideways are inclusive of the Downtown, Omni, and Brickell People Mover Loops. Scope also included underwater bridge inspections and load rating analysis of all guideways, emergency and non-emergency structural analysis, and design of repairs and retrofits.

Additionally, BPA carried out selective LRFR analyses of the 23,233 ft. long Miami Metromover system. A distinctive feature of these loops is that the guideway consists of nonredundant (fracture critical) superstructures made of a dual, parallel steel girder system that carries the Metromover cars. A live load carrying capacity evaluation was performed on approximately 10% of the spans representative of the structural features within the entire system. Ultimately, the evaluation determined that all units selected possess adequate load carrying capacity.
