Bridge structures are subject to harsh conditions and require ongoing maintenance and rehabilitation to achieve long-term performance. Through the investigation of thousands of bridges and notable bridge failures, our bridge engineers have learned that improved bridge construction and rehabilitation designs are accomplished through a better understanding of the problems. Our knowledge of bridge performance is supported by expertise in structural, electrical, and mechanical engineering as well as laboratory and field testing and instrumentation.
Our bridge engineers have extensive experience conducting field investigations of bridge deck, superstructure, and substructure problems involving a wide range of bridge materials and structure types. In addition to traditional highway and rail bridges, we have special expertise in heavy movable structures, including bascule, swing, and vertical lift bridges.
