Services
Structural Engineering
Our structural engineering services focus on designing safe, efficient frameworks for residential and commercial buildings. We address challenges in new construction and renovations, ensuring compliance with regional regulations and client-specific needs.
Seismic Retrofits
We specialize in seismic retrofits to enhance building resilience against earthquakes. Our solutions include reinforcing foundations, walls, and joints using cost-effective techniques tailored to local geological conditions.
Temporary Excavation Shoring
For urban sites with sloped or dense terrain, we provide temporary excavation shoring to stabilize soil and protect adjacent structures during foundation work, ensuring safety and project efficiency.
Forensic Engineering
Our forensic engineering services investigate structural failures in residential and multifamily buildings. We provide expert testimony and remediation plans based on rigorous analysis of light-frame construction issues.
Cross-Laminated Timber Installation
We implement cross-laminated timber systems to reduce carbon footprints in residential and public projects. This method improves site efficiency and avoids emissions-intensive concrete solutions.
