How to Hire a 3D Laser Scanning Company
Scanner types, accuracy specs, point cloud deliverables, scan-to-BIM evaluation, and a complete checklist for choosing the right 3D scanning provider.
Quick Answer
Hire a 3D scanning company that uses terrestrial laser scanners (Leica RTC360, FARO Focus, or equivalent) rated ±2-6mm accuracy, has a documented QC process with deviation analysis, and delivers point clouds in standard formats (E57, RCP).
Get 3 quotes. Compare scan position count, deliverable formats, and LOD level — not just price. Ask for sample deliverables from similar projects. Verify they carry professional liability insurance.
Scanner Types Compared
Not all scanners are equal. The right scanner depends on your project's accuracy requirements, building size, and deliverable needs.
| Type | Examples | Accuracy | Best For |
|---|---|---|---|
| Terrestrial (tripod-mounted) | Leica RTC360, FARO Focus Premium, Trimble X9 | ±2-6mm | Interior detail, MEP, as-built BIM, renovation design |
| Handheld / Mobile | Leica BLK2GO, NavVis VLX3, GeoSLAM ZEB | ±10-20mm | Rapid spatial capture, facility walkthroughs, large areas |
| Drone LiDAR | DJI Zenmuse L2, Leica BLK2FLY | ±10-30mm | Rooftops, facades, large exterior areas, inaccessible spaces |
| Long-range | Leica RTC360 LT, FARO Focus S 350 | ±3-8mm | Bridges, tunnels, industrial facilities, large open spaces |

Red Flags When Hiring
If you encounter any of these, ask for clarification or get a second opinion.
Uses only handheld or mobile scanners for detailed interior work
Handheld scanners (BLK2GO, Matterport) achieve ±10-20mm accuracy — adequate for basic spatial capture but insufficient for renovation design, MEP coordination, or as-built BIM. Terrestrial scanners deliver ±2-6mm.
Cannot explain their QC process
Professional scanning firms run deviation analysis, verify registration accuracy with control points, and produce QC reports with heat maps. No QC process means no guarantee that your point cloud is accurate or complete.
Does not deliver raw point cloud files
The registered point cloud is your permanent 3D record. Firms that only deliver 2D plans from scans lock you into returning to them for any future data extraction. Always receive the E57 or RCP files.
Quotes without visiting your site
3D scanning scope depends on access constraints, obstructions, scan position count, and environmental conditions (reflective surfaces, dust, temperature). Accurate pricing requires a site visit or detailed photos and floor plans.
No scan-to-BIM capability and no BIM subcontractor
If you need BIM deliverables, the scanning firm should either model in-house or have an established BIM subcontractor. Handing raw scans to an unrelated modeling firm causes data transfer issues and accountability gaps.
Claims "sub-millimeter accuracy" for building scanning
Building-scale laser scanning achieves ±2-6mm accuracy in practice. Claims of sub-millimeter accuracy apply only to laboratory conditions or metrology-grade scanners, not field conditions with temperature variation, dust, and vibration.
7 Questions to Ask Before You Hire
"What scanner hardware will you use on my project?"
Terrestrial scanners (±2-6mm) are the standard for BIM and renovation. If they propose handheld-only, your deliverables may lack precision for design work.
"What is your registration accuracy target?"
Ask for their target RMSE and how they verify it. Professional firms use survey control points and produce QC reports with deviation heat maps.
"How many scan positions will my project require?"
Scan position count drives cost and coverage completeness. More positions = better coverage but higher cost. Ask how they determine positioning.
"What deliverable formats will I receive?"
Ensure E57 (universal) and your software-specific format (RCP for Autodesk, PTS for other platforms). Always request the raw registered point cloud.
"Do you handle scan-to-BIM modeling in-house?"
If you need a BIM model, in-house modeling means single-source accountability. If they subcontract, ask who the BIM partner is and review their work.
"How do you handle obstructions and gaps?"
Furniture, equipment, and occupants create scan shadows. A professional firm documents coverage gaps and offers solutions (return visits, supplemental measurements).
"Does your quote include revisions?"
Point cloud delivery is typically final, but BIM models often require revision. Confirm whether one round of model revisions is included in the price.
Frequently Asked Questions
What should I look for when hiring a 3D laser scanning company?
+
Look for five things: (1) experience with your building type and industry, (2) terrestrial laser scanners rated ±2-6mm accuracy per ISO 10360-8, (3) a documented QC process with deviation analysis, (4) deliverables in standard formats (E57, RCP for point clouds; DWG for CAD; RVT for BIM), and (5) professional liability insurance. Ask for sample deliverables from similar projects and verify they can explain USIBD Level of Accuracy standards.
How much does 3D laser scanning cost?
+
3D laser scanning costs $0.40-$0.80 per square foot for commercial buildings, with a typical minimum of $2,500-$3,500 per project. A 10,000 sq ft commercial building costs $4,000-$8,000 for scanning alone. Add $2-$8 per square foot for scan-to-BIM modeling depending on LOD level. Day rates range from $2,500-$5,000 for a scanning crew. Get 3 quotes and compare scan position count, deliverables, and LOD level — not just price.
What is the difference between terrestrial and handheld scanners?
+
Terrestrial (tripod-mounted) scanners like the Leica RTC360 deliver ±2-6mm accuracy at 1-2 million points per second — the standard for renovation design, BIM, and MEP coordination. Handheld/mobile scanners like the BLK2GO deliver ±10-20mm accuracy and are faster for large area capture but lack the precision for detailed as-built documentation. Most projects benefit from terrestrial scanning. Some firms use handheld scanners for initial spatial capture, then add terrestrial scans in critical areas.
What point cloud file formats should I receive?
+
Request your point cloud in E57 format (open, universal standard) and RCP/RCS format (Autodesk ecosystem — Revit, Recap, Navisworks). E57 is the safest long-term archive format because it is vendor-neutral. If working with non-Autodesk software, also request LAS or PTS format. Always receive the registered, colorized point cloud — not just the derived 2D plans or BIM model.
How long does a 3D scanning project take?
+
Field scanning takes 1-3 days for a typical 10,000-30,000 sq ft commercial building. Each scan position takes 2-5 minutes with modern scanners. Post-processing (registration, cleanup, colorization) takes 3-7 business days. Scan-to-BIM modeling adds 2-6 weeks depending on building complexity and LOD level. Total project turnaround: 2-3 weeks for point cloud only, 4-8 weeks for scan-to-BIM deliverables.
Do I need a licensed surveyor for 3D scanning?
+
In Florida, if the scanning project involves boundary determination, property corners, or any work that constitutes "surveying and mapping" under Florida Statutes Chapter 472, a licensed PSM must sign and seal the deliverables. For interior as-built documentation without boundary work, licensure requirements vary. Best practice: hire a scanning firm that either holds a PSM license or partners with a licensed surveyor, especially for projects requiring stamped deliverables.
What is the difference between LOA and LOD?
+
LOA (Level of Accuracy) is a USIBD standard that defines point cloud accuracy — LOA 10 is the least precise (±50mm), LOA 50 is the most precise (±5mm). LOD (Level of Development) is a BIMForum standard that defines how much detail a BIM model contains — LOD 200 (generic placeholders) through LOD 400 (fabrication-ready). LOA applies to scanning accuracy. LOD applies to modeling detail. Both should be specified in your project scope.
Can 3D scanning work in occupied buildings?
+
Yes. Modern terrestrial scanners are non-contact, silent, and emit eye-safe laser light. Scanning can proceed in occupied offices, hospitals, schools, and retail spaces during normal operations. The main constraint is that people and moving objects create noise in the point cloud. Professional firms plan scan schedules to minimize occupant interference — scanning during off-hours in high-traffic areas and during normal hours in less occupied spaces.
