Our Services

WestSpan Engineering provides structural and civil engineering services for residential, light commercial, and small-scale infrastructure projects throughout Eastern Washington, Northern Idaho, and Northeast Oregon.

All engineering services are performed or directly supervised by a licensed Professional Engineer.

Structural Engineering

We provide practical structural engineering for new construction, remodels, and structural modifications — focused on designs that meet code, are straightforward to build, and keep your project moving.

Whether you're planning a new build, opening up a wall, or dealing with structural repairs, we work directly with you to deliver clear, buildable solutions without unnecessary complexity.

Our experience includes wood-framed construction, timber systems, and steel design, allowing solutions to be tailored to the specific structure and project requirements.

Typical structural services include:

  • Foundation design and structural evaluations

  • Beam and column sizing for new and existing structures

  • Load-bearing wall removal and beam design

  • Deck and porch design

  • Retaining wall design

  • Pole buildings and shop structures

  • Structural repair evaluations and retrofit design

  • Plan review and stamped structural drawings

We work closely with homeowners, contractors, and design teams to provide responsive service, clear communication, and engineering that fits how projects are actually built.

Civil Engineering

We provide focused civil engineering services for site development and small infrastructure projects — delivering practical designs that coordinate with the site, utilities, and overall construction.

Our approach is straightforward: clear grading, effective drainage, and coordination that keeps projects moving through design, permitting, and construction.

Typical civil services include:

  • Site grading and drainage design

  • Stormwater planning and basic system layout

  • Utility coordination and service connections

  • Support for small-scale public works and site improvements

  • Construction observation and field coordination

We focus on civil design that works in the field — not just on paper — helping projects move smoothly from design through construction.
