Frequently Asked Questions
What is "builder-led engineering"?
It means our leadership's deep background in construction informs every engineering decision we make. We anticipate field issues that traditional firms might miss, ensuring our architectural engineering solutions are practical and efficient to build.
How does your process help with getting plans approved faster?
Our focus on constructability and our use of AI to validate plans against local codes before submission helps to reduce plan check delays. By delivering cleaner, more accurate structural engineering and MEP sets, we minimize the back-and-forth with city reviewers.
What areas do you serve?
Our systems are built to handle building codes in key markets nationwide, including California, Texas, Florida, and Arizona. While we are a leading structural engineer in the Bay Area, our expertise covers all of Northern California and Southern California, from major cities like Los Angeles and San Diego to the specific jurisdictions of the Peninsula. We are fully equipped to be the MEP consultant for your next project, whether it's in Austin, Miami, or the Hamptons.
How do you approach Title 24 compliance for homes with large amounts of glass?
We are experts in California's energy code and specialize in the performance-based method for Title 24 compliance. This allows us to preserve an architect's home design vision, including large windows and open concepts, by strategically modeling energy trade-offs.
Can you handle the complete MEP scope for a custom home?
Yes. Our MEP engineers provide a fully coordinated solution. This includes efficient HVAC design, full electrical engineering for modern homes with complex lighting and EV charging needs, and performance-based plumbing design.
What types of residential projects do you specialize in?
We specialize in high-end custom home design, complex remodels, and JADU additions. Our team has extensive experience delivering permit-ready plans for projects throughout California, with a deep portfolio in demanding municipalities like Palo Alto and Los Altos.
What makes Spacial different from a traditional engineering firm?
Our process is builder-led, which means every plan we produce is viewed through the lens of constructability. For residential architects, this means our structural and MEP engineering services result in plans that are not just compliant, but are also practical to build in the field, saving time and reducing costly rework during construction.
