Structural Engineering Services in Colorado

Colorado presents unique structural challenges that our engineers address on every project: • Snow loads — Colorado's mountain and Front Range communities require design snow loads ranging from 30 psf to over 100 psf depending on elevation, exposure, and local jurisdiction. We calculate ground and roof snow loads per ASCE 7. • Expansive soils — Much of the Front Range sits on expansive clay soils that swell and shrink with moisture changes. Foundation designs account for these conditions with deepened footings, post-tensioned slabs, or drilled pier systems. • Wind loads — Eastern Colorado plains experience higher wind exposure categories than the urban corridor. We design lateral systems to meet local wind criteria. • Seismic considerations — While Colorado is in a low-to-moderate seismic zone, certain soil types and building categories require specific seismic detailing. • Freeze-thaw cycles — Foundation depth, concrete mix design, and drainage must account for Colorado's repeated freeze-thaw cycling.

We handle the full spectrum of structural engineering needs across Colorado: • Load-bearing wall removal and modifications • Home additions — second stories, rear additions, garage conversions • New residential and light commercial construction • Foundation design — basements, crawl spaces, slab-on-grade, drilled piers • Retaining wall engineering (typically walls over 4 feet) • Deck and pergola engineering for permit submittal • Roof structure design for snow load modifications • Seismic and wind retrofits • Foundation repair and underpinning design • Pre-purchase structural evaluations

1. Initial phone consultation — Call us with your project details. We'll discuss scope, timeline, and provide a firm quote — often on the same call. 2. Site visit (if needed) — For inspections and some design projects, we visit the site to assess existing conditions. 3. Engineering analysis — We perform structural calculations per code, analyzing loads, forces, and member capacities. 4. Drawing preparation — We produce structural drawings and details coordinated with architectural plans. 5. PE review and stamp — A Colorado-licensed Professional Engineer reviews, signs, and seals the final plans. 6. Building department submittal — You receive a complete, submission-ready package. We're available to address plan review comments if they arise.
