When your project demands precision, reliability, and code-compliant structural design, you need a partner who understands the unique building environment of Tigard. From commercial developments along Highway 99W to residential additions in neighborhoods near Fanno Creek, every structure requires thoughtful engineering that accounts for local soil conditions, seismic activity, and Oregon's stringent building codes.
SFA Design Group brings decades of experience delivering comprehensive structural engineering solutions across the Pacific Northwest. The firm's portfolio spans commercial buildings, residential expansions, and institutional facilities—each project engineered with meticulous attention to load paths, material performance, and long-term durability. Structural failures cost U.S. property owners over $8.5 billion annually in repairs and retrofits, making upfront engineering investment essential.
Whether you're planning a multi-story mixed-use development or renovating a historic structure in downtown Tigard, you'll benefit from engineering that integrates design analysis, material specifications, and regulatory compliance into one seamless process. The team works closely with architects, contractors, and permitting agencies to keep your project on schedule and within budget.
Tigard sits in the Tualatin Valley, where varied soil compositions—from clay-rich deposits near the Tualatin River to well-drained gravels on hillsides—directly impact foundation design and structural loads. Expansive clay soils can exert lateral pressures exceeding 5,000 pounds per square foot , requiring engineered solutions that prevent cracking, settlement, and moisture infiltration.
Your project also faces seismic considerations unique to the Cascadia Subduction Zone, where engineers must design for both high-frequency shaking and long-duration ground motion. The team incorporates base isolation, shear walls, moment frames, and energy-dissipation systems tailored to your building's occupancy and risk category. From retail centers near Washington Square to industrial facilities in the River Terrace Business Park, every design meets or exceeds ASCE 7 seismic provisions.
Commercial projects benefit from value engineering that optimizes material use without compromising safety—substituting steel for timber where appropriate, specifying post-tensioned slabs for longer spans, and coordinating MEP penetrations to preserve structural integrity. Call us today at 503-305-8077 for Structural Engineering in Tigard.
You gain access to a full spectrum of structural capabilities designed to support projects from concept through construction administration:
- Detailed structural analysis using finite element modeling and load-tracing software to validate member sizes and connection details
- Code compliance review for IBC, OSSC, and ACI standards, including fire ratings, live load reductions, and wind load calculations
- Material specifications for concrete, steel, mass timber, and masonry systems tailored to Tigard's climate and seismic profile
- Construction document preparation with clear annotations, schedules, and details that streamline contractor bidding and permitting
- On-site observation and shop drawing review to ensure field conditions match engineered intent and approved plans
Over 60% of construction delays stem from design conflicts and incomplete engineering documentation, underscoring the value of thorough upfront planning. Whether you're expanding a school, building a medical clinic, or adding a second story to your home, you'll receive drawings and calculations that inspectors approve on the first submittal.
