Frequently Asked Questions
Common questions about as-built documentation for infrastructure
What is as-built documentation?
As-built documentation records the actual existing conditions of a building or structure — dimensions, layout, MEP systems, structural elements — using 3D laser scanning for survey-grade accuracy (±2-4mm). Unlike original design drawings, as-builts reflect what was actually built, including field changes and modifications.
How accurate is laser scanning for as-built documentation?
Our Trimble X12 achieves 1.0mm accuracy at 10 meters, and our NavVis VLX3 mobile scanner achieves ±5mm (±3mm with control points). This far exceeds manual tape measurement accuracy of ±0.5-1 inch.
What file formats do you deliver?
We deliver registered point clouds in E57 (open standard), RCP/RCS (Autodesk ReCap), LAS/LAZ (GIS), and OBJ (3D mesh). All formats are BIM-conversion-ready for import into Revit, ArchiCAD, or other BIM platforms.
How long does as-built documentation take?
Field scanning typically takes 1-3 days depending on building size and complexity. A 10,000 sqft commercial building requires 4-8 hours of scanning. Deliverable preparation adds 3-10 business days for processing and QC.
How much does as-built documentation cost?
Costs range from $1,000-$4,000 for residential properties to $3,000-$15,000 for commercial buildings, depending on size, complexity, and deliverables. 2D CAD drawings from scan data add $0.15-$0.35/sqft. Contact us for a free project estimate.
Can you scan occupied buildings?
Yes, we regularly scan active facilities including offices, hospitals, and manufacturing plants with minimal disruption to operations. Our mobile SLAM scanner (NavVis VLX3) captures spaces in walk-through mode for the fastest field work.
What is the difference between as-built drawings and record drawings?
As-built drawings document actual existing conditions through field verification (measuring what is really there). Record drawings are revised design documents updated by the contractor to show changes made during construction. As-builts reflect reality; record drawings reflect intended changes to the original design.
When are as-built drawings legally required?
Many jurisdictions require as-built documentation before issuing a certificate of occupancy. Federal projects (GSA, DoD, USACE) mandate as-built records. Building codes, fire codes, and ADA compliance may also require as-built documentation.
