Bridge Design & Inspection

Collins’ civil and structural engineers build on expertise in all phases of large and small transportation projects to provide practical solutions to clients in the construction industry, state and local government, railroads, transit systems, and other commercial owners. Bridge design projects have included both new construction and rehabilitation for bridge types ranging from single span to high level, multi-span structures.

Collins also provides hands-on above and underwater bridge inspection, performed by full-time in-house crews of NBIS-qualified engineers and engineer-divers. Collins’ insistence on gaining firsthand knowledge through on-site bridge inspections—above- and below water—produces unique insights into the needs of the nation’s infrastructure, leading to the authoring of operations manuals and assisting in the implementation of industry protocol.
