#legacy

Proudly rooted in Pasadena.

25 years of combined structural engineering, construction expertise, seismic research, and recognized industry leadership inform every project we support today.

Representative institutions and projects with which we have worked include:

Post-Disaster Residential Rebuilds (Altadena and the Palisades): Structural engineering and advanced Passivhaus design principles for modern residential rebuilds across Altadena following regional wildfire events.
Specialized Seismic Evaluation & Retrofits: Engineering analysis, non-ductile concrete remediation, and vibration mitigation solutions—including structural strengthening for the Chumash Auditorium at Cal Poly SLO.
Institutional & University Peer Review: Independent technical peer review frameworks and structural evaluations for the University of California system and major public facilities.
High-Profile Landmark Peer Review: Specialized seismic isolation and structural peer review contributions for major regional developments, including SoFi Stadium and the Lucas Museum of Narrative Arts.
Mission-Critical & Advanced Infrastructure: Structural design and resilience planning for hyper-scaler cloud and AI data center facilities.
Commercial, Industrial & Feasibility Studies: Comprehensive structural design for commercial distribution warehouses, supermarkets, and pre-acquisition engineering feasibility studies for real estate portfolios.
National Code Development: Active leadership and committee contributions to national structural engineering standards, including the writing committees for ASCE 41 (Seismic Evaluation and Retrofit of Existing Buildings) and ASCE 7.

Some Past Project Highlights

With over 20 years of combined experience, the Roble Hill team is proud to showcase select projects from their extensive backgrounds in engineering and construction. Note: these featured projects were completed while working at previous firms.

Commercial Construction

Construction of a new rooftop restaurant space in Downtown Los Angeles, featuring a custom steel deck and rooftop garden. The project also included large operable glass doors, all built on top of an existing non-ductile concrete building that underwent seismic retrofit as part of the overall project scope.
