At S3DA, we’re transforming the construction design process with innovative solutions that eliminate wasted time, budget overruns, and missed deadlines. By partnering with architecture firms, developers, and property owners, we tackle complex engineering challenges head-on.

Despite rapid advancements in technology, construction design has remained outdated. Many companies focus on isolated design elements, leaving architects to handle the challenging task of merging them. At S3DA, we take a unique approach by integrating structural and MEP design into one seamless process.
We’re eliminating the “pass-the-baton” model. By serving as a single point of responsibility, we cut down on design errors, omissions, and conflicts that typically occur when several parties are involved.
Our fully licensed engineers bring decades of combined experience, practical, results-driven designs, and a strong commitment to client needs.
Delivered more than 4,600 successful structural engineering design projects across the commercial, residential, and industrial sectors.
We design according to local codes and adhere to Title 24, all while aiming for safety and lowering construction costs.
Whether it’s project size, system type, timeline requirements, or occupied properties, we solve your most pressing engineering design challenges.
The simple key to our success, and yours, has been providing professional quality services on time and on budget.

MEP consultants offer design, analysis, code compliance review, system troubleshooting, and construction oversight for building mechanical, electrical, and plumbing systems.
Structural design encompasses foundation, framing, seismic analysis, load calculations, and retrofit planning for safe, durable, and economical buildings.
Yes, we offer full remote MEP and structural engineering support with seamless communication and deliverables nationwide.
We provide Structural, MEP, and Fire Protection design in 26 states, including key markets such as California, Florida, and Texas, along with a growing list of other jurisdictions. Our team is licensed in many states and can also collaborate with local partners where required. For any new project, share the address and authority having jurisdiction (AHJ), and we’ll confirm exactly what disciplines we can stamp in that location.
For a typical single-family residential house, our standard timeline is about 3 weeks for the MEP (Mechanical, Electrical, and Plumbing) design and about 4 weeks for the structural design, once we have all the required information and drawings. If we are handling both Structural and MEP, we coordinate the schedule so the disciplines align and you receive a fully integrated set of drawings within that overall timeframe.
