The firm
A PE-Led Practice Built for Code & Permitting
Structexa is a nationwide licensed engineering firm — not a design studio. We produce defensible analysis, coordinated construction documents, and stamped submittals that jurisdictions, contractors, and owners can rely on.
Our teams support developers, municipalities, contractors, and property owners on civil, structural, architectural, MEP, and HVAC scopes — from feasibility through plan-check response. Every engagement is governed by applicable building codes, local amendments, and constructability standards so drawings perform in the field, not just on paper.
- Licensed PE oversight on every discipline
- Calculations, details & stamped drawing sets
- Agency submittals & plan-check coordination
We hold ourselves to the standard of the seal — technically sound decisions, clear documentation, and accountability from concept through permit approval.
Technical standards
How We Engineer
Documented QA/QC, code alignment, and field-ready detailing on every submittal.
Code compliance
IBC, ASCE 7, local ordinances, Title 24, and jurisdiction-specific checklists applied to each scope.
Discipline coordination
Civil, structural, architectural, and MEP models aligned to eliminate clashes before permit.
Constructible details
Sections, schedules, and notes written for contractors — fewer RFIs, faster inspections.
Practice areas

Client references
Client References
Feedback from developers, contractors, municipalities, and owners on plan-check outcomes, technical responsiveness, and buildable stamped deliverables.
Structexa took our 38-lot subdivision from preliminary grading through county sign-off. Their drainage report and utility profiles matched what planning asked for — we cleared second review without a redesign cycle.
On our four-story apartment stack, their MEP sheets coordinated shaft routing with the structural grid before we poured. Title 24 documentation was complete the first time the city inspector walked the job.
Their stormwater report and BMP sizing for our arterial widening held up under public works review. Comment responses were technical, not boilerplate — that kept our council hearing on schedule.
We needed a hillside wood-frame addition stamped for snow and seismic loads. Structexa issued foundation and lateral calcs our architect could drop straight into the permit set — building department picked it up in one pass.
