Making Challenging Architecture Possible
Structural engineering solutions for complex architecture, demanding sites, and existing buildings throughout Southern & Northern California.
Engineering Solutions for Thoughtful Architecture
3S Prime Engineering is a California structural engineering consulting firm providing structural design and engineering services throughout Southern and Northern California.
Our work ranges from new construction homes and hillside residences to major remodels and additions, commercial projects, shoring and foundation systems, and seismic upgrades.
We collaborate closely with architects, contractors, developers, and property owners to develop structural solutions that support the architectural vision while addressing constructability, site conditions, building codes, and project economics.
OUR APPROACH
Every project presents a different structural challenge. We focus on understanding the architecture first, identifying critical structural issues early, and developing solutions that are efficient, practical, and well integrated with the overall design.
COLLABORATION
- Successful projects require close coordination between the structural engineer, architect, contractor, consultants, and owner.
- We strive to be an engineering partner throughout the project—not simply a consultant producing structural drawings.
