Commercial
Commercial Structural Engineering
Tenant improvements, podium multifamily, mixed-use, and new commercial construction. Stamped structural drawings, lateral system design, and construction-phase support — coordinated with your architect and design team.
Who I Work With
Architects, developers, general contractors, and building owners who need a licensed PE structural engineer to carry a commercial project from schematic design through permitted drawings and into construction. I work with your team or directly with the owner — however the project is structured.
Project Types
- Tenant improvements — structural alterations, opening enlargements, mezzanines, HVAC support framing
- Rooftop equipment and solar supports — gravity and seismic anchorage, existing roof framing adequacy
- Podium multifamily — wood Type V over a concrete or post-tensioned podium; the Portland mid-rise standard
- Mixed-use — retail or parking at grade, residential above; lateral system coordination across building types
- New commercial construction — full structural package from foundation to roof framing
- Structural alterations — existing building modifications, load-path changes, seismic upgrades
Selected Projects
Saltwood North & South (Slabtown, NW Portland) and Raleigh 22 (NW Portland) — podium multifamily structural design, wood-frame residential over concrete podium, lateral system and foundation work. CedarTree Hotel (Hillsboro, OR) — hospitality structural design, gravity and lateral system, coordination with architectural and MEP teams. See the projects page for more.
What's Included
- Framing plans, sections, and connection details
- Foundation design and geotech coordination (I work with your geotech, or recommend one)
- Lateral system design — shear walls, moment frames, or braced frames as appropriate
- Calculations package for permit
- Stamped drawings — Oregon-licensed PE
- BDS correction response
- Construction support — RFI responses, submittal review, field questions
Typical Fees
- Small TI (under 5,000 SF) — $3,500–$8,000
- Medium TI / apartment building — $8,000–$25,000
- New commercial construction — fee proposal on scope; contact for a project-specific number
FAQ
Do you work with architects?
Yes — directly with architects, developers, and GCs. I coordinate with the full design team or work directly with the owner, depending on the project delivery method. Early structural involvement saves time and cost in design development.
What codes do you design to?
Oregon Structural Specialty Code (OSSC), IBC, ASCE 7 for loads (gravity, seismic, wind), AISC 360 for steel, NDS for wood, and AISI S100/S240 for cold-formed steel framing. All work is stamped by an Oregon-licensed PE.
Can you handle the seismic design too?
Yes — lateral system design including seismic and wind is included in all commercial structural packages. Shear walls, moment frames, and braced frames depending on the building type, height, and seismic design category.
