Structural Design for a Custom Pool, Spa, Pergola & Waterfall Feature in San Diego, CA
S3DA Design provided structural engineering services for a custom outdoor pool and spa project in San Diego, California, including a 1,715 SF pool/spa, a 90 SF detached triangular pergola, and a 290 SF overhead trellis with waterfall feature.
S3DA’s Scope:
- Structural load calculations for wind, seismic, hydrostatic, dead, and live loads
- Reinforced concrete design for pool/spa shell, walls, floor, bond beam, and baja shelf
- Structural plans, sections, reinforcement details, notes, and specifications
- Foundation and framing plans for the detached triangular pergola
- Concrete column, beam, and wall reinforcement details
- Structural support design for overhead trellis framing and waterfall feature
Key Challenges & Solutions:
This project required careful coordination of multiple outdoor structural elements, including reinforced concrete pool walls, hydrostatic loading, seismic design, pergola framing, trellis walls, and waterfall support. S3DA’s structural team engineered each component to work safely within San Diego’s seismic design requirements while maintaining the architectural vision for a high-end outdoor living space.
The Result:
S3DA delivered a complete structural design package with permit-ready calculations, plans, sections, and reinforcement details—supporting a durable, code-compliant, and visually integrated custom pool environment. S3DA’s California-based engineering team brings structural and MEP expertise nationwide, with a focus on practical, cost-effective solutions and deadline-driven delivery.
