The Hacienda at Mission San Luis Rey project was recently honored with a 2025 PCBC Gold Nugget Award of Merit in the category of Best Service Enriched 55+ Community IL/AL/Memory Care. The PCBC Gold Nugget Award showcases the most exciting trends in design, planning and building. ISE is proud to have partnered with the design-build team and architectural and landscape firms to deliver a robust, code-compliant structural solution tailored to the project’s unique site and mission-driven aesthetic. As a licensed structural engineering firm in California—and nationally—the ISE team brought over two decades of front-line experience to bear on this prestigious community.
Structural Planning & Frame Design
Working closely with civil engineers and architects, ISE engineered the structural framework to support the Mission Revival style. This included:
- Designing foundations and lateral load systems to mitigate seismic forces in coastal Southern California.
- Specifying wood‑framed, glulam, and steel systems in alignment with fabrication and architectural requirements, ensuring durability and design flexibility.
Soil & Site Conditions
The Oceanside site posed seismic and liquefaction challenges. ISE worked in coordination with contractors to integrate engineered deep-soil mixing and load-pier foundations—dramatically improving bearing capacity and accelerating construction timelines.
Courtyard & Amenity Structural Coordination
ISE collaborated in integrating hardscape and landscape elements—like courtyards, paseos, and outdoor structures—into the overall structural plan. Walkways, amenity shading structures, and pickleball court foundations were all engineered to align with drainage, load, and access requirements while preserving architectural intent.
How Structural Expertise Made the Difference
- Holistic Structural Integration: Thoughtful structural systems harmonized with architectural vision and functional landscaping.
- Safety & Seismic Resilience: Innovative foundation engineering ensured site stability in a high-liquefaction coastal zone.
- Delivery & Coordination Expertise: ISE’s project planning and field presence supported streamlined permitting and construction phases across disciplines.
ISE Structural Engineers – Trusted Partner in Project Success
The ISE team was instrumental in translating the Hacienda’s architectural vision into a resilient, code-compliant built form. Engineered foundations, framing systems, and multidisciplinary coordination contributed to not only project efficiency and structural integrity but also to the wellness-driven design that earned BIASC’s SAGE award.
ISE Structural Engineers—based in Temecula and licensed across more than 28 states—specializes in cost‑effective structural planning, schematic design, and construction administration.
