Services
Structural Engineering
We provide comprehensive structural engineering services for new buildings and renovations, specializing in wood, steel, concrete, and masonry. Our team ensures compliance with current codes while balancing economic and safety considerations. Clients benefit from tailored solutions for commercial, residential, and institutional projects.
Seismic Retrofit
Our seismic retrofit expertise includes strengthening historic buildings and modern structures against earthquake risks. We analyze existing systems and implement cost-effective solutions that preserve architectural integrity while meeting modern safety standards. This service is critical for California properties in high-risk zones.
Excavation Shoring
We design temporary and permanent shoring systems for deep excavations, including soldier beams, tiebacks, and soil nail walls. Our solutions address complex site constraints like adjacent structures and underground utilities, ensuring safety during construction of foundations and underground facilities.
Building Shoring
We engineer temporary support systems for building facades and structures during renovations or demolitions. This includes lateral bracing for historic walls and underpinning for foundation modifications, ensuring stability throughout construction phases for projects like museums and stadiums.
Underpinning
Our underpinning services stabilize existing foundations for deep excavations or structural additions. Techniques include slant-drilled steel and jet-grout cut-offs, enabling safe modifications to buildings adjacent to new construction while maintaining structural integrity during ground-level changes.
