At LEVEL, we are committed to common sense, real-world solutions. We pioneered LEVEL because, after years spent exploring all disciplines of civil and structural engineering in the building industry, we continually encountered the missing fundamentals in our own trade. These lost elements of service culture & exceptional business practice inevitably cost owners & entities untold stress and frustration; contractors lost time & money, realtors & lenders were left unable to satisfy their client's needs. We concluded that our capacity for A&E services could function at a higher level, thus, LEVEL Engineering & Inspections was founded. We serve your interests & provide knowledgeable, expert design, inspections, analysis, forensics, recommendations, and reporting. Whether your need is for permitting, forensics; new, remodel, or repair engineering designs; foundation problems; civil or architecture - let us help you navigate your Civil, Commercial, Residential Structural Engineering needs.

"Gang is super. He’s very knowledgeable and personable. He talking through all my questions and concerns and helped me sort through all the details to arrive at a well reasoned conclusion for what needs to be done next."

He explained there isn't anything structurally wrong with the house and the reasons we could be experiencing the issues we're having. He made several suggestions on what to do and how to go about alleviating the issues. Very personable."

Structural Engineering questions, answered by experts

In San Francisco, structural engineers often recommend steel moment frames, high-strength reinforced concrete, and advanced rebar for earthquake resistance. For challenging soils, helical piers and micropiles provide stability. Base isolation systems and fiber-reinforced polymers are increasingly used for retrofitting older buildings. When planning a project, discuss with your structural engineer which materials best address seismic risk, corrosion from coastal air, and your property’s unique soil conditions.

Helpful?

In San Francisco, project timelines depend on complexity and permitting. Residential structural assessments and design typically take 2–4 months, while commercial or multi-unit projects may extend to 6–18 months. Construction for seismic retrofits often lasts 1–6 months. Factors like permit approvals, neighbor notifications, and required geotechnical studies can add time, so consult your structural engineer early to set realistic expectations.

Helpful?

San Francisco offers a variety of structural engineering specialists, including seismic retrofit contractors, residential structural engineers, and experts in high-rise or historic building reinforcement. You’ll also find geotechnical engineers for soil analysis and contractors skilled in deep foundation work. When selecting a contractor, ask about their experience with local seismic codes, soft-story retrofits, and building reinforcement for your specific property type.

Helpful?

San Francisco’s seismic activity and coastal climate shape structural engineering decisions. Earthquake-resistant designs and deep foundations are crucial, especially in areas with bay mud or liquefaction risk. The moist, foggy air can accelerate steel corrosion, so protective coatings are important. While freeze-thaw cycles are rare, variable soil types require thorough structural assessments to ensure long-term stability and resilience against local environmental challenges.

Helpful?

In San Francisco, homes built before 1978, those with soft-story designs, or properties in liquefaction zones often benefit from a structural assessment. Look for signs like foundation cracks, sloping floors, or doors that stick. If you’re planning renovations or haven’t had a seismic retrofit, schedule a structural engineer to evaluate your home’s foundation, framing, and overall stability for earthquake readiness.
