Collins Engineers, Inc.

In 1979, Collins Engineers, Inc. opened its doors in Chicago providing engineering services in structural and transportation analysis and design, and underwater engineering. It was in the field of underwater engineering that Collins pioneered the use of professional engineers as diving inspectors in the evaluation of underwater structures. Today, Collins is an ENR Top 500 Design Firm and provides design and analysis services coupled with field experience to the transportation, marine, construction, and land development industries. Collins’ insistence on obtaining firsthand knowledge means that our engineers are on the project from start to finish, from the initial on-site inspection to the design of repairs, from performing the construction administration to following up with construction inspection. Not only does Collins incorporate this valuable knowledge into its engineering services, Collins applies it to the advancement of the industry as a whole. Continually on the leading edge of standards and methodology, Collins provides engineering ingenuity and solutions to complex problems, and realistic, honest answers.
