Coastal Structural Design for a New Custom Residence in Nehalem, OR
S3DA Design is providing structural engineering design for a new 3,590-square-foot residential home in Nehalem, Oregon, on a site that already includes an existing workshop. This project requires a carefully engineered structural system tailored to coastal wind exposure and the seismic demands of Tillamook County.
S3DA’s Scope
- Structural loading analysis for seismic, wind, snow, dead, and live loads
- Code-based design in accordance with the Oregon Residential Specialty Code and ASCE 7
- Foundation design and structural calculations
- Crawlspace stem wall design
- Shear wall and load-bearing wall analysis
- Design of columns, beams, floor joists, and headers
- Truss bearing connection design
- Stair stringer and guardrail post design
- Structural connector and load path coordination
Key Challenges & Solutions
Designing a new residence in coastal Oregon requires more than standard residential engineering. The structure must respond to elevated lateral demands from wind and seismic forces while maintaining an efficient load path from roof to foundation. S3DA addresses these conditions through detailed structural analysis of all major framing components, coordinated lateral system design, and carefully engineered connections to support stability, safety, and code compliance.
The Result
The result is a comprehensive structural design package developed to support permitting, construction coordination, and long-term performance. By engineering every major structural component as part of an integrated process, S3DA helps deliver a safe, buildable, and code-compliant custom home solution backed by the firm’s single-source design approach and nationwide experience.
