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.
