The crew you call first
Our crew blends licensed Structural and MEP engineers with people who have spent years in the field. We care about how plans read at the city counter and how they feel on site. Every project combines AI coordination with human judgment and a real stamp.

Frequently asked questions
What does Spacial do?
Spacial is your one engineering partner for your construction project.
We handle the core building systems so you do not have to juggle multiple consultants:
Structural engineering
Mechanical engineering
Electrical engineering
Plumbing engineering
Energy efficiency, including Title 24 and other energy code compliance
We deliver a fully coordinated engineering set, stamped by licensed engineers, ready to submit for permit.
Do you cover structural engineering?
Yes. Spacial has an in-house team of licensed structural engineers.
We produce the full structural engineering package for your project, coordinated with mechanical, electrical, plumbing, and energy efficiency work, and provide a permit-ready set stamped by licensed engineers.
What's included in your fixed-fee proposal?
Our proposal includes a complete set of stamped, permit-ready plans covering the full scope of agreed-upon services, whether it's standalone structural engineering, full MEP design and Title 24 compliance, or a complete package. There are no hidden fees or surprises.
What is the revision process like if I make a change to my design?
A: Our process is built for iteration. When you submit a design change, our system automatically flags the affected engineering components. Updated MEP and structural plans are regenerated in a fraction of the time a traditional firm would take, keeping your project moving forward.
Can Spacial coordinate directly with city reviewers?
Yes, we see ourselves as your partner in securing permit approval. Our team can coordinate with city reviewers to clarify any questions regarding our structural or MEP designs, including specifics on SWPPP requirements, building setbacks, or material specifications.
How quickly can Spacial deliver an engineering set?
On average, sets are delivered within 7 to 10 business days. We provide precise quotes and delivery timelines within 24 hours of receiving your architectural plans. To read more about our process, click here.
How do you handle complex site requirements like hydrology and grading?
We handle them comprehensively. Our process begins by incorporating all relevant site data, including the topographic survey and geotechnical reports. Our teams are proficient in hydrology, BMPs, and developing a stormwater pollution prevention plan (swppp) to meet local regulations. We ensure the grading plan and foundation design are perfectly suited to the site’s unique conditions.
How does your AI platform work with architectural plans?
Our proprietary platform is designed for seamless integration. It can analyze architectural CAD files or even convert 2D to 3D plans to identify the most efficient structural and mechanical routes. For example, our system can take your floor plans and intelligently convert floor plans to MEP, generating an initial layout for our engineers to refine, ensuring optimal duct design and system placement.
What does "builder-led engineering" mean for my project?
It means your plans are designed to be built efficiently in the real world. Our leadership's background as custom home builders allows us to evaluate load paths, MEP system integration, and field feasibility to prevent the costly rework and delays common with traditional engineering.
What is the role of the licensed engineer in your process?
The licensed engineer is central to our process. While our AI engineering platform accelerates production, every single plan, whether it's for electrical systems or a complex foundation and types drawing, is reviewed, validated, and ultimately stamped by a licensed professional. Human expertise is the final authority and ensures all deliverables are accurate and code compliant. AI never replaces our engineers. It surfaces conflicts, checks code, and speeds up modeling. Our licensed engineers still own the design, validate the assumptions, and sign the drawings.
