Contractor Services
Collins brings unparalleled experience in the specialty fields of erection and construction engineering.
For over thirty years, Collins has worked closely with some of the country’s largest contractors to provide engineering services in support of their construction activities. We work with the contractor’s staff to understand the problem in need of a solution and to utilize the work methods and equipment preferred by the contractor.
Our experience includes construction engineering for the design of shoring towers and formwork, temporary earth retention structures and cofferdams, and extends to complex designs such as girder erection, bridge jacking and moving, demolition sequencing, and the re-analysis of straight and curved girders to accommodate continuous deck pour sequences and the rehabilitation of movable bridge spans.
