Bridge Inspection and Repair

Enhancing public safety and instilling confidence in our nation’s infrastructure

Accurate and consistent safety inspection, load rating, structure inventory and appraisal and repair

TRC’s inspectors employ multiple means of access to inspect bridge structures of varying size and complexity. We conduct regular in-depth bridge inspections in accordance with the National Bridge Inspection Standards (NBIS) and AASHTO Manual for Bridge Evaluation. These inspections identify areas of distress and ensure that appropriate maintenance can be completed before impacting motorist safety or increasing overall structure life-cycle costs. 

 Adhering to established FHWA guidelines and stringent QC/QA procedures, our inspection work is accurate and consistent. Our assignments include small and medium-sized bridges, culverts, railroad grade separations, viaducts, and major water crossings in both rural and urban environments. TRC also performs load capacity ratings of both new and existing bridges. These ratings are based on the Load and Resistance Factor Rating (LRFR) method using the evaluation methodologies of the AASHTO Manual for Conditional Evaluation of Bridges, as well as the allowable stress method or the load factor method (LFR) depending on the needs of our clients.
