Meet the Founder

Supun Jayawardhane is the founder and structural design lead of Structural Express. He has spent his career doing one thing: producing structural packages that plan reviewers accept — foundations, framing, lateral systems, calculations, and the drawings that tie them together. Final stamping, where a project requires it, is performed by a licensed Professional Engineer in the project's state.
His work spans single-family homes, additions, remodels, ADUs, and light-commercial structures across U.S. jurisdictions, including high-seismic California projects requiring full lateral analysis — shear walls, diaphragms, collectors, moment frames, and strong-wall systems designed to IBC, IRC, CBC, and ASCE 7.
"I believe structural engineering should be accurate and fully aligned with permit requirements. My role is to eliminate delays, simplify communication, and provide clear, code-compliant solutions that help professionals build with confidence."
Supun leads a small, hand-picked engineering team and personally reviews every package before it goes out. When you book a consult, you talk to him — the same engineer who will run your calculations, not an account manager reading a script.
Beyond project work, he has built internal design tools, calculation systems, and QA frameworks used across the firm — because consistent engineering comes from consistent process, not luck.
A Worldwide PE Network Behind Every Project
Supun has built a strong network of licensed Professional Engineers (PEs), builders, architects, and specialty consultants across the U.S. and beyond. This network allows Structural Express to connect the right engineer to the right project, coordinate multi-jurisdiction requirements, and source peer reviews or stamped packages when the scope demands it.
Access to licensed PEs across multiple states for stamping, review, and jurisdiction-specific requirements.
Relationships with builders, framers, and contractors who can help turn approved drawings into completed structures.
When a project needs geotechnical, seismic, wind, or materials expertise, we tap the right specialist.
The network means quicker answers on local codes, plan-check preferences, and alternative compliance paths.
