Streamlined Solutions

At S3DA, we’re disrupting construction design with efficient solutions that break the cycle of wasted time, budget overruns, and missed deadlines. We collaborate with architecture firms, developers, and owners to solve complex engineering challenges.

A Better Approach

While technology has advanced rapidly, construction design remains stuck in the past. Too often, companies focus on one design aspect, leaving architects with the burden of merging designs. At S3DA, we take a different approach. Our innovative method integrates structural and MEP design acting as a single point of contact to reduce rework, waste, and costs.
