Bridge Inspection

Collins’ insistence on gaining firsthand knowledge through on-site inspections—both 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. Continually on the leading edge of standards and methodology, Collins provides engineering ingenuity and solutions to complex problems, and realistic, honest answers.

Bridge maintenance and safety are key issues that governments face daily. Collins understands the consequences of failures in undetected parts of bridge structures: major unforeseen repair costs, inconvenience to the travelling public, or possibly even loss of life. We appreciate the insights gained and the problems that can be avoided simply by having a fully integrated picture of the structure in question.

As a result, Collins provides a full range of bridge management services to owners. We provide hands-on above and underwater bridge inspection, performed by full-time in-house crews of engineers and engineer-divers. Upon completion, Collins can provide repair recommendations, as well as design of repairs. From top to bottom and start to finish, Collins is a one-stop shop for an owner’s bridge management needs.
