What We Do
We’re a Los Angeles-based structural engineering firm focused on design that gets built, clear documents, practical details, and structures that perform in real conditions.
Structural Engineering Services in Los Angeles
Design-forward structural engineering for residential and commercial projects across Los Angeles. Our team supports architects, developers, contractors, and owners with code-compliant structural design, seismic analysis, and clear plan sets that make permitting and construction smoother.
Structural and Civil Engineering Services
San Diego Structural Engineering provides comprehensive structural and civil engineering services across Los Angeles and Southern California. Led by licensed Professional Engineers, we deliver permit-ready documents, practical solutions, and code-compliant designs tailored to local project requirements. We support homeowners, architects, contractors, developers, attorneys, and property managers from planning through construction.
Residential Structural Engineering in Los Angeles
Residential structural engineering is a core project type in Los Angeles, including custom homes, remodels, additions, and hillside construction. We deliver structural design and analysis that align with architectural plans while meeting all building code and permitting requirements. Our services cover new custom homes, additions, ADUs, and garage conversions, along with hillside construction, complex framing systems, and foundation design based on site conditions. We also evaluate load-bearing wall modifications to maintain structural integrity during renovations. This approach helps homeowners and design teams reduce construction risk while achieving safe, durable, and cost-effective results.
Seismic Retrofitting
Seismic retrofitting is essential for many Los Angeles buildings constructed prior to modern seismic design standards. We provide seismic retrofit design for residential, commercial, and multi-family structures to improve structural safety and ordinance compliance.Our retrofit experience includes soft-story retrofits, wood-frame strengthening, anchorage improvements, and upgrades for non-ductile concrete structures. We develop retrofit strategies that balance structural performance, construction feasibility, and cost control while helping property owners comply with local seismic retrofit programs.
Structural Assessments
Structural assessments evaluate the condition, safety, and performance of existing buildings. They are commonly required for real estate transactions, renovation planning, damage investigations, and long-term maintenance. We conduct property condition evaluations, due diligence reviews, post-damage inspections, and structural performance analyses. Our reports provide clear documentation and practical recommendations for repairs, strengthening, or retrofits aligned with client goals and project constraints.
Structural Repairs
Our structural repair design services restore damaged or deteriorated systems while improving long-term performance and code compliance. Projects often address aging structures, settlement, construction defects, or environmental damage. We design repairs for foundations, framing, concrete, and steel, and provide strengthening solutions that increase capacity with minimal disruption. Our approach prioritizes practical, cost-effective designs that enhance safety and extend service life.
Commercial Structural Engineering
Our commercial structural engineering services support new construction, building additions, rehabilitation, major repairs, and seismic or code-driven retrofits. We design steel, concrete, wood, and masonry systems while working closely with architects, developers, and contractors to deliver efficient, buildable solutions. We provide value engineering and constructability reviews to control costs and reduce schedule risk. Our team also evaluates and upgrades historic and aging structures, developing retrofit strategies that enhance safety, preserve character, and extend service life.
Retaining Wall Design
Retaining wall design is essential for hillside development and grading projects throughout Southern California. We design structurally stable systems that support grading, drainage, and overall site development objectives. Our services include cast-in-place concrete walls, mechanically stabilized earth systems, slope stabilization, and temporary or permanent earth retention solutions. We support projects from planning and permitting through construction, maintenance evaluations, and repair design.
Civil Engineering Design
Our civil engineering services support site development, infrastructure improvements, and accessibility compliance, coordinated closely with structural design. We provide grading and drainage plans, roadway and access improvements, ADA curb ramp and sidewalk design, stormwater management, and utility coordination. Integrating civil and structural engineering streamlines permitting and improves overall site performance and compliance.
Construction Support
Construction-phase engineering support ensures structural systems are installed in accordance with approved plans and specifications. We help contractors address field conditions while maintaining structural performance and code compliance. Our services include structural observations, field reviews, RFI responses, shop drawings and submittal reviews, and design clarifications during construction. Ongoing coordination reduces delays, prevents rework, and keeps projects aligned with approved engineering documents.
tructural, Civil, and Accessibility Expert Witness
We provide expert witness services in structural engineering, civil engineering, and accessibility compliance for attorneys, insurers, contractors, property owners, and developers throughout Los Angeles and Southern California. Our licensed Professional Engineers deliver objective, defensible opinions based on detailed analysis and real-world construction experience. Our services include structural failure investigations, construction defect evaluations, civil dispute analysis, and ADA compliance reviews, including slip-and-fall cases. We prepare repair scopes, cost assessments, expert reports, and provide deposition or trial testimony, supported by field investigations, engineering calculations, documentation, and applicable code review.
Bridge Engineering
Bridge engineering services support transportation infrastructure and specialized structural systems throughout Southern California. We provide bridge structural design, rehabilitation, and construction support for public agencies, developers, and design-build teams. Our bridge engineering work includes bridge structural analysis and design, rehabilitation and strengthening of existing bridges, coordination with roadway and civil engineering teams, andconstruction-phase structural support. Our experience allows us to develop safe, efficient, and constructible transportation structures designed for long-term performance and durability
