Frequently Asked Questions

How much does as-built documentation cost?
As-built documentation costs depend on building size and deliverables needed. Residential: $2,500-$9,000. Commercial: $5,500-$40,000. Industrial with MEP: $20,000-$100,000+. Per-square-foot rates typically range from $0.20-$0.70/sqft for scanning. Traditional manual measurement is cheaper upfront but less accurate and takes longer.
Do I need as-built documentation for permit closeout?
Most jurisdictions require as-built drawings for building permit closeout and certificate of occupancy. Requirements vary by municipality but typically include floor plans, MEP layouts, and site plans reflecting actual construction. 3D laser scanning produces more accurate as-builts than traditional contractor redlines.
