Building Code (statewide)
Oregon Structural Specialty Code (OSSC), 2022 edition
Oregon Service Area
Licensed MEP, structural, civil, and energy-compliance engineering for Sisters projects (population approximately 3,022 based on the 2024 American Community Survey) — designed to the 2021 IBC with extensive Oregon amendments and permitted with the local jurisdiction. We confirm Sisters's governing code editions and any local amendments with the permit office at project kickoff.
Coordinated mechanical, electrical, and plumbing design — engineered as one system, stamped by licensed professionals, and documented for fast permit approval.
Structural systems designed to the loads your state actually imposes — gravity, seismic, wind, and snow — with drawings built to get approved the first time.
Site engineering that clears local review — grading, drainage, and utilities designed to each jurisdiction's published standards from day one.
Energy compliance handled as engineering, not paperwork — documentation matched to the exact code edition your permitting jurisdiction enforces.
Apex Grid organizes related search intents under this single canonical Sisters engineering hub so owners, architects, contractors, developers, facility managers, and public agencies can find the relevant discipline without duplicate location pages.
Mechanical and HVAC design, electrical power and lighting, plumbing systems, equipment coordination, controls, and multidisciplinary MEP documentation.
New structural systems, renovations, additions, adaptive reuse, equipment support, condition assessments, repair design, and existing-building analysis.
Site planning, grading, drainage, stormwater, utility coordination, accessibility, paving, and permit-support documentation.
Commercial energy-code compliance, COMcheck support, envelope and lighting coordination, mechanical-system efficiency, and performance documentation.
Subsurface investigation coordination, foundation recommendations, due diligence, property condition assessments, and renovation feasibility support.
Permit drawings, calculations, specifications, agency responses, deferred-submittal coordination, corrections, and construction-phase engineering support.
Offices, retail, restaurants, mixed-use properties, tenant improvements, renovations, additions, and change-of-use projects.
Manufacturing, warehouses, logistics facilities, process-support spaces, clean environments, laboratories, and technology facilities.
Hospitals, clinics, medical offices, schools, universities, civic buildings, public facilities, and mission-critical renovations.
Multifamily housing, senior living, hotels, resorts, residential amenities, and building-system modernization.
Government facilities, public works, utility coordination, transportation-support facilities, resilience, and capital-improvement projects.
Facility condition assessments, structural evaluations, energy upgrades, equipment replacements, seismic and wind reviews, and repair programs.
Sisters may enforce local amendments on top of the statewide baseline. We verify the governing editions and amendments with the Sisters permitting authority before design begins.
Oregon's uniform statewide code makes plan review consistent across jurisdictions, though metro Portland and Washington County (Hillsboro's Silicon Forest) run high-volume review. Stormwater is a defining permitting issue — Portland's on-site infiltration and green-infrastructure requirements are among the strictest in the country — and Cascadia seismic detailing is expected on essential facilities.
Oregon licenses PEs by comity for qualified out-of-state applicants and accepts electronic seals; the state applies specific rules on seal and signature requirements for digital submittals.
With licensed PEs, architecture coordination subject to project-specific credential verification, and a multi-discipline engineering team, we take on Sisters projects of any size — with fast quote turnaround on every request.
