Team-first Focus

We believe great buildings come from trust, teamwork, and strong collaboration.

 Engineering Confidence. Building Possibilities.

At 40th Parallel Structural Engineering, we love helping projects take shape across Colorado and Wyoming — from custom homes in the mountains to commercial builds on the plains. Our role is simple: bring clarity, confidence, and approachable expertise to your project so you can focus on creating a space that lasts.

We understand that building here comes with unique challenges. Expansive soils, snow loads, tricky sites, local codes…these are everyday realities. We make engineering solutions straightforward, reliable, and constructible, so your ideas move from design to build with less stress and more trust.
