Professional As-Built Documentation & Survey-Grade Verification
Your existing blueprints are probably wrong. Buildings shift, renovations go undocumented, and original drawings rarely survive decades of changes. We use 3D laser scanning to capture the exact physical state of your building and convert that data into reliable 2D CAD floor plans, elevations, and structural sections you can actually build from.
2D CAD As-Built Floor Plans — The Architectural Standard: Precision .dwg and .pdf floor plans, elevations, and structural cross-sections delivered within days, not weeks.
BOMA Measurement & Area Analysis — Revenue-Focused Documentation: Certified area calculations following BOMA 2024 standards for office, industrial, and retail assets.
Structural & MEP Record Drawings — Engineering-Grade Clarity: Detailed documentation of exposed structural steel, MEP routing, slab-to-ceiling heights, and mechanical systems.
Understanding As-Built Documentation
As-built documentation is the process of recording the true physical condition of a building — not how it was designed, but how it actually exists today. Over time, renovations, tenant improvements, and construction changes create a gap between what the original blueprints show and what’s really there. According to a study by Autodesk and FMI, decisions made using inaccurate building data cost the global construction industry an estimated $88.69 billion in rework in a single year . Our as-built documentation eliminates that gap by using LiDAR technology to capture every wall, column, pipe, and opening with extreme accuracy, giving your team a reliable foundation for design, renovation, and facility management.
Key Benefits of As-Built Documentation Services
Accurate As-Built Floor Plans & Record Drawings
Our as-built workflow captures the exact physical state of your structure using high-speed LiDAR scanners, delivering detailed CAD floor plans and registered point clouds. These comprehensive data sets make it easy to visualize existing conditions, verify structural changes, and provide the reliable starting point required for complex renovation planning — without the guesswork of manual tape measurements.
Eliminating Design Clashes & Field Errors
Outdated blueprints are the leading cause of costly field errors. When your architect designs around drawings that don’t match reality, the result is clashes, change orders, and schedule delays. Our “Field-to-File” process ensures that every wall, opening, and MEP run is documented as it actually exists, so your design team starts with the truth — not a 20-year-old guess.
Certified BOMA 2024 Area Analysis & Asset Monetization
For property managers and real estate teams, accurate area calculations directly impact revenue. Our BOMA 2024-certified measurements ensure your rentable area figures are defensible, compliant, and optimized for leasing. We serve office, industrial, retail, and mixed-use properties across North America, providing the documentation your leasing team needs to maximize every square foot.
Who Needs As-Built Documentation?
As-built documentation serves a wide range of professionals across the construction, real estate, and facility management industries. Architects use our as-built floor plans as the accurate starting point for renovation and adaptive reuse projects. General Contractors rely on existing conditions data to plan construction sequencing and avoid costly field surprises. Property Managers and Real Estate Teams use BOMA-certified area calculations to optimize leasing revenue and maintain compliance. Engineers need precise structural and MEP documentation for system upgrades, seismic retrofits, and code compliance reviews. Facility Maintenance Teams use our record drawings to understand building layouts, locate hidden systems, and plan routine maintenance without guesswork. Whether you manage a single heritage building or a national portfolio of commercial assets, accurate as-built documentation is the foundation every project decision should be built on.
National As-Built Coverage & Portfolio Verification
From heritage landmarks in Toronto to logistics centers in Dallas and high-rises in New York, our team delivers accurate as-built records for national portfolios. We coordinate multi-site scanning campaigns across North America, ensuring consistent deliverables and unified documentation standards regardless of where your buildings are located. One point of contact. One standard of quality. Every building in your portfolio.
What is As-Built Documentation?
As-built documentation is a set of drawings, plans, or models that represent the actual physical condition of a building or site as it exists today — including all changes, renovations, and deviations from the original design. Unlike design drawings that show how a building was intended to look, as-builts show how it actually was built. Using 3D laser scanning, we capture millions of precise data points to create a complete digital record of the existing conditions, which is then converted into 2D CAD floor plans, elevations, sections, and structural drawings. This documentation is essential for renovation planning, facility management, BOMA compliance, historical preservation, and any project where accurate existing conditions data is required.
How We Create Your As-Built Documentation
Step 1 — Site Scanning:
Our field team deploys high-speed terrestrial LiDAR scanners to capture every surface of your building. Each scan position records millions of 3D data points, documenting walls, columns, openings, MEP systems, and structural elements. A typical commercial floor takes 2-4 hours to scan completely.
Step 2 — Data Processing & Registration:
Back in our office, we register all scan positions into a single, unified point cloud. This creates a complete 3D digital record of your building that can be measured, sectioned, and explored from any angle.
Step 3 — CAD Drafting & Delivery:
Our drafting team converts the registered point cloud into the deliverables you need: 2D CAD floor plans (.dwg), elevations, structural sections, MEP layouts, reflected ceiling plans, or full Scan-to-BIM models in Autodesk Revit. You receive production-ready files that your architects and engineers can open and start working with immediately.

Frequently Asked Questions
How accurate are your as-built drawings compared to old blueprints?
Our terrestrial LiDAR scanners capture data at ±2mm to ±5mm accuracy. This is dramatically more accurate than historical blueprints or manual tape measurements, which can be off by inches or even feet after decades of undocumented changes. The result is as-built floor plans that reflect the exact physical reality of your building today.
What is the difference between as-built documentation and Scan-to-BIM?
As-built documentation typically refers to 2D CAD deliverables — floor plans, elevations, sections, and details in .dwg format. Scan-to-BIM goes further by creating an intelligent 3D model in Autodesk Revit with embedded data about materials, systems, and spatial relationships. If you need 2D plans for renovation or leasing, as-built documentation is the right fit. If you need a full digital twin for BIM coordination, Scan-to-BIM is the better choice.
Do you provide BOMA-certified area calculations?
Yes. We provide certified area calculations following the latest BOMA 2024 standards for office, industrial, retail, and mixed-use properties. Our measurements are defensible for leasing purposes and comply with current industry measurement standards.
