What We Do
Specialists in field-verified existing conditions — plus the full suite of drafting services to take your project from site survey to permit-ready set.
Our core specialty. We visit your site, take precise measurements, and produce fully drafted, field-verified as-built drawings — accurate records of the building exactly as it stands today.
From as-built survey to approved permit set — we produce complete, jurisdiction-specific drawing packages ready for building department submission, built on your existing conditions drawings.
Precise measured drawings of historic structures and renovation projects where existing conditions must be captured with exceptional care and detail before any new work begins.
CAD and BIM drafting for new construction, renovations, and additions — often paired with our as-built survey to ensure every new drawing is grounded in verified existing conditions.
Large-scale as-built surveys and documentation for retail, office, hospitality, and multi-unit residential — coordinated across multiple floors and disciplines.
Revit BIM models built from your as-built survey data — giving architects, contractors, and owners a rich spatial model to design and coordinate from with confidence.

About Red Bridge Design
Founded in 2011, Red Bridge Design has built its reputation on one thing: getting existing conditions right. We've completed over 8,500 as-built surveys and drawing projects for architects, contractors, developers, and property owners across San Francisco and the broader SF Bay Area — from Victorian flats in the Mission to commercial buildings in SoMa and multi-family properties in Oakland and Berkeley.
When a San Francisco renovation hits an unexpected wall configuration, when SF DBI requires existing conditions drawings for a permit, or when a property sale needs accurate floor plans — clients across the Bay Area call us. We show up, we measure, and we deliver drawings you can bet your project on.
Standard 5–7 business days; rush 48-hour service available.
We refine drawings until you're 100% satisfied — no extra charge.
Delivery in DWG, RVT, PDF, and DXF — whatever your workflow needs.
We work with clients nationwide via cloud collaboration and virtual site surveys.
How It Works
Tell us your property address, approximate square footage, and what you need the drawings for — renovation, permit, sale, or facilities management. We'll respond within 4 hours with a fixed-fee proposal.
Our team visits your site with laser measuring equipment and methodically records every wall, opening, ceiling height, and structural element. We can also work from your photos or laser scan data for remote projects.
We convert your field measurements into clean, scaled drawings and share a draft via our client portal. You mark up changes directly in the browser, and we incorporate every revision — typically within 24 hours.
Final drawings are delivered as PDFs and native CAD/BIM files via secure download — permit-ready and built to your specifications. We retain your files for 3 years for easy future updates.
Client Voices
"Red Bridge Design delivered a complete as-built set for our 8,000 SF commercial space in under a week. The drawings were incredibly accurate — the building department had zero comments. I've stopped going anywhere else for as-builts."
"We hired Red Bridge Design for a historic renovation and their measured drawings were exceptional — capturing every quirk of the 1920s building with the level of detail our preservation consultant required. Accuracy and detail are clearly their priority."
"As an architect, I rely on Red Bridge Design for as-built surveys before every major renovation. Their field measurements are always spot-on and the drawings come back clean and permit-ready. They're a genuine extension of our office."
"We needed as-builts fast for a tenant build-out and Red Bridge delivered in 3 days. The drawings were detailed enough that our contractor barely needed to visit the site before pricing the job. Outstanding service."
