As one of the oldest and largest public transit systems in the U.S., the Massachusetts Bay Transportation Authority (MBTA) connects commuters and travelers in the greater Boston area. MBTA is one of only two U.S. transit agencies that operates all five major modes of land and water transportation. Due to PRIME AE’s transparent, trusting relationship with MBTA, we were reselected to complete critical safety inspections for over 50 commuter railroad bridges on five MBTA lines. The project includes load rating and underwater inspections for several fixed bridges as well as inspection for two movable bridges.
PRIME AE synchronized all the required pre-inspection services with multiple stakeholders, including railroads, vendors, and municipalities. Our team coordinated the oversight and follow-up scheduling to validate that the inspections were conducted as planned and keep the project moving forward.
Our highly qualified inspection team have over 10 years specialized experience and functional railroad and safety operations and right-of-way training. Load-rated bridges are inspected according to MBTA standards as well as those of several national railway associations and the FHA.
The final product included the comparison of current findings versus those in prior inspection reports to determine any changes in condition. PRIME AE provided a comprehensive report on each of the identified bridges, detailing the location, framework, and repair priorities and recommendations.
