At Wills, we offer proven expertise in the development of designs for new structures and the inspection, evaluation and rehabilitation designs for existing structures including bridges, culverts and miscellaneous structural concrete work.

We can provide corresponding structural expertise in the areas of municipal engineering, highway engineering, and transportation planning and design.


Our structural team is skilled at bridge engineering including condition surveys, inspections, investigations and bridge structural evaluations.

We typically provide a comprehensive written report, and can also provide recommendations for remedial work accompanied by detailed construction cost estimates for budgetary purposes.

  • Following the completion of the detailed structure inspections, we are able to prepare rehabilitation contracts for the proposed work.
