Bridges and Structures

Bridge Engineering

Bridges serve as critical links in the reliable and efficient flow of people, commodities and emergency services over our roadways. And their aesthetic appearance can become important to the heritage of a community. DEA understands the increasingly complex set of challenges, from funding to regulations, from public relations to technological issues, which bridge projects can involve.

Our approach begins with the people, clients, and communities served by the structure. We study community concerns, site opportunities, and design and construction issues before beginning the design process. We provide high-quality, value-based engineering services for all types and sizes of bridges, and for a diverse client base. The results are designs that are tailored to the communities they serve. From the initial investigation through planning and concept development to final design and construction, we respond to client and community requirements with designs that serve today’s needs while accommodating tomorrow’s growth.

Structural Engineering

DEA provides comprehensive, innovative structural engineering services to public agencies, developers, and corporations throughout the United States. Our services include preliminary through final structure design, detailing, and construction administration for buildings and related civil structures. We also provide seismic risk analysis, and seismic structural analysis and detailing for rehabilitation of existing structures. We have worked with several of our environmentally conscious clients to help them achieve their goal of LEED certification for their buildings.

We are committed to working collaboratively with our clients to develop solutions that provide secure, safe and sustainable structures, working to improve the quality of life while demonstrating stewardship of the built and natural environments.
