As-Built Survey Cost in Florida

A manual as-built survey costs $1,000-$4,000 for residential and small commercial properties. A 3D laser scanning as-built costs $3,000-$8,000 for the field work and point cloud registration. Scan-to-BIM modeling adds $0.50-$10.00+ per square foot depending on the Level of Detail (LOD) and building complexity. A standard office renovation at LOD 300 typically costs $1.80-$3.50 per square foot for the BIM model — on top of the scanning field work.

Seven main factors: (1) Building size — larger buildings cost more but have lower per-sq-ft rates. (2) Complexity — MEP-heavy buildings (hospitals, data centers) cost 2-4x more than empty shells. (3) Survey method — manual is cheaper upfront but 3D scanning captures more data with fewer return visits. (4) Deliverable format — 2D CAD costs less than 3D BIM. (5) Level of Detail — LOD 200 massing vs LOD 350+ fabrication. (6) Access constraints — occupied buildings, above-ceiling work, or restricted areas add cost. (7) Location — South Florida commands 15-20% higher rates.

The field cost is higher — $3,000-$6,000 for scanning vs $1,500-$4,000 for manual measurement of a small commercial building. However, scanning often has lower total project cost because it eliminates return visits (which affect 79% of manual as-built projects), captures complete data on the first trip, and produces BIM-ready deliverables faster. For buildings over 5,000 sq ft, scanning typically costs less overall when you factor in avoided rework and additional site visits.

LOD (Level of Detail/Development) defines how much information is modeled in the BIM. LOD 200 is massing — approximate shapes and locations, good for space planning. Cost: $0.50-$2.10/sq ft. LOD 300 is detailed — accurate dimensions of walls, floors, ceilings, MEP systems, structural elements. Standard for design. Cost: $1.80-$7.50/sq ft. LOD 350+ is fabrication-ready — includes connections, hangers, fittings, and routing. Required for prefabrication and clash detection. Cost: $4.00-$18.00+/sq ft.

A residential as-built survey for a renovation project typically costs $1,000-$3,000 using manual measurement methods. This includes field measurements, a floor plan with dimensions, and elevation data as needed. If BIM deliverables are required (Revit model), add $1,500-$5,000 for 3D scanning and modeling. For most residential renovations under 3,000 sq ft, manual measurement with 2D CAD output is the most cost-effective approach.

Many Florida counties require an as-built survey at different stages: before renovation (existing conditions documentation), during construction (foundation verification, form board surveys), and at completion (final as-built for certificate of occupancy). The scope varies by county and project type. For additions and major renovations, the building department typically needs existing floor elevations, structural locations, and setback measurements. Check your county requirements before starting — your surveyor can advise on what is needed.
