Do I Need an Engineer to Build a Metal Building in Utah?

Utah jurisdictions — Salt Lake City, Provo, Ogden, St. George — require an engineer-sealed plan set for commercial and industrial metal buildings, and the PE seal is the standard requirement for the foundation and site-specific structural sheets. The seal must show the engineer's name, Utah PE number, and date, with the engineer in responsible charge. The manufacturer supplies PE-sealed drawings for the building itself — the rigid frames, purlins, and girts — but the foundations, site-specific load verification, and the permit set are designed and sealed by the Utah engineer of record. Owner-builders don't escape the requirement: the building department asks for the seal regardless of who drew the plans, and the engineer must verify the building for Wasatch seismic risk, snow loads, and collapsible soils.

The engineer designs the foundations for footings below frost on collapsible soils — the engineer verifies bearing so irrigation and snowmelt can't settle the frames after erection, and verifies the rigid frames for rigid frames braced for Wasatch Front seismic loads with snow-rated purlins — the engineer checks unbalanced snow on monoslopes against the lateral system. Purlins, girts, eave struts, and rod bracing go on the sealed plan set — member sizing for gravity and lateral loads, bracing layouts, and the anchor-bolt detailing that ties the building to foundations designed for Wasatch seismic risk, snow loads, and collapsible soils. Bring the manufacturer's anchor-bolt plan and column reactions, a geotechnical report for the lot, and the building dimensions and eave height. Wasatch Front frames take seismic loads and unbalanced snow together — the engineer checks monoslope drift against the lateral bracing system.

Use this checklist before engaging an engineer for your metal building: • Engineer of record holds an active Utah PE license, verifiable on the state roster • Foundations designed for the manufacturer's anchor-bolt reactions against Wasatch seismic risk, snow loads, and collapsible soils • Rigid frames, purlins, and girts verified for Wasatch seismic risk, snow loads, and collapsible soils per ASCE 7 • Rod bracing or portal-frame lateral system detailed on the sealed set • Anchor bolts, base plates, and hairpin ties detailed for uplift and overturning • Eave height, clear span, and bay spacing called out and checked • Geotechnical report reviewed before foundation design • Engineer confirms they'll respond to plan-check corrections on sealed sheets
