Services
Hillside Construction Engineering
Hillside Construction Engineering focuses on designing structures for sloped sites, incorporating deep footings, retaining walls, and soldier piles. The service addresses geotechnical challenges to ensure stability and safety for residential and commercial buildings on hillsides. Our engineers comply with local building codes while optimizing cost and durability for hillside developments.
Soft Story Seismic Retrofitting
Soft Story Seismic Retrofitting strengthens weak groundfloor frames to improve earthquake resistance. The process involves adding shear walls, moment frames, or bracing to meet current seismic standards. We apply this retrofit to residential apartments, commercial buildings, and historic structures requiring seismic upgrades.
Seismic Design
Seismic Design creates structural systems that withstand earthquake forces while maintaining architectural intent. Our approach integrates analysis of ground motion, material behavior, and foundation interaction for safe performance. We deliver designs for new construction, retrofits, and specialized projects such as earth retaining and shoring systems.
Fire Rebuild Projects
Fire Rebuild Projects provide rapid structural design and reconstruction after wildfire damage. We focus on using fireresistant materials and efficient framing to restore safety and code compliance. Our team coordinates with owners, contractors, and agencies to expedite permits and minimize downtime.
Historical Building Restoration
Historical Building Restoration preserves architectural heritage while upgrading structural integrity. We reinforce unreinforced masonry, replace deteriorated timber, and retrofit hidden connections to meet modern standards. Our work includes bell tower reinforcement, stone masonry repair, and sensitive detailing that respects original design.
