Services We Offer

At DDA, we offer a wide variety of services including inspections, evaluations, new designs, rehabilitation designs, asset management, construction engineering, planning and environmental assessments, third party and constructability reviews, as well as contract administration and construction inspections for structures.
DDA can provide engineering services equivalent to those services provided by large multi-national firms yet we are of a size that enables the client to always deal with a Project Manager who is a Bridge Engineer and who can address the client’s needs.
