Bringing your ideas and innovations to life

Rooted Here

We know the soil, snow, local weather, and codes that shape construction in Colorado and the Mountain West.

Direct Access

When you call, you’re talking directly to Daniel or Dana — the engineers personally doing the work.

Buildable Design

We strive to find practical solutions that are easy to implement and true to the architect’s overall vision.

Team-first Focus

We believe successful projects come from trust, teamwork, and strong collaboration.

 Engineering Confidence. Building Possibilities.

At 40th Parallel Structural Engineering, we love helping projects take shape across the Rocky Mountain Region — 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, high wind and 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.

Building smarter in Colorado & Mountain West starts here.
