Structural Design for a New Home
Complete stamped structural design for a custom home: foundation, framing, beams, shear walls and connections.
What the work involves
For custom homes, large open plans, steel beams, tall walls, high wind or seismic regions, and anything outside the residential code's prescriptive tables, a structural engineer designs the full load path from roof to foundation. Deliverables include stamped foundation and framing plans, beam and header schedules, lateral (shear wall or braced frame) design and connection details. The architect or designer leads layout while the engineer makes it stand up.
Local conditions we plan for
- Deep frost penetration
- Expansive clay soils (Pierre Shale)
