Structural Engineering Services

We walk our clients through every step of the consulting and structural engineering process. At S3DA Design, we believe that the process of design, construction or renovation of a structure is as important as the end result. For this reason, we work closely with our clients; gathering relevant information at each step about their needs, as we proffer pragmatic structural engineering services. We are proud of having some of the best engineers in California offering Structural Engineering services. We work closely with relevant local authorities and clients and have a reputation for meeting high expectations. For years now, we have successfully executed conceptual, preliminary, and detailed structural design projects in various areas of Structural Engineering and analysis across California, US. Our quality assurance program ensures that high-quality contract documents are delivered for each project.  Our knowledge of a wide variety of structure types and construction materials always provides the client with a cost-effective and high-quality structural solution.
