Services

High-performance buildings, engineered for value and built as drawn

Building science shapes our designs from the first sketch: a continuous air and thermal envelope, controlled moisture paths and a structure sized to the real loads. Each system is value-engineered as the design develops, and every detail is drawn so the builder can price it accurately and build it as intended.

Designing in the foothills

Mountain sites need site-specific design

Snow, wind and slope change quickly with elevation along the Front Range. Every structure is designed to the code edition and design criteria your jurisdiction has adopted, confirmed for your site before calculations start.

How we work

From first call to stamped drawings

A clear scope and fee up front, then the same engineer from proposal to permit.

  1. Scope & proposal

    We review your drawings, site and goals, then send a written proposal with scope, fee and schedule.

  2. Design & calculations

    Building design plans, structural framing, foundation design and calculations, coordinated as they develop.

  3. Permit

    Stamped drawings and calculations for submittal, plus responses to plan review comments.

About

Eric Crowley, PE

I studied at Arizona State University and graduated with a B.S. in Civil, Environmental and Sustainable Engineering. My career started in heavy civil construction, building roadways, bridges and drainage facilities, and I served as onsite engineering project manager on a desalination plant.

From there I moved into design: water and wastewater treatment plants, mining and disposal facilities, and then residential structures as a designer for an engineering firm that provided design for about 30% of the Phoenix tract-home market. That work grounded me in residential framing and foundations.

I founded ENGenious LLC in 2016. It is a small firm on purpose. When you call, you talk to the engineer who will design your project and sign the drawings.

Common questions

Working with an engineer

I already have a designer. Can you do just the structural engineering?

Yes. We regularly engineer projects from other designers' drawings, and we coordinate directly with your designer so the structure fits their design.

Do I need an engineer for my project?

It depends on the project and the jurisdiction. Many building departments require engineered drawings for new homes, additions, accessory buildings and anything outside the code's prescriptive limits. Send us the details and we will tell you what your building department is likely to require.

What do you need from me to prepare a proposal?

The property address, a description of the project, and any existing drawings, surveys or soils reports. Photos help for remodels and additions.

Do you work outside the Denver area?

Yes. We work throughout Colorado and are also licensed in Arizona. Design criteria such as snow and wind loads are confirmed with each jurisdiction.
