Scan to BIM is the process of converting 3D laser scan point cloud data into intelligent, as-built Building Information Models (BIM). Using terrestrial LiDAR scanners (FARO, Leica, Trimble), millions of 3D data points are captured from a building's existing conditions. This point cloud data is then processed and modeled in Autodesk Revit or equivalent BIM software to produce accurate as-built architectural, structural, and MEP models at LOD 200–500.
3D laser scanning achieves ±2–4mm spatial accuracy depending on equipment — approximately 10x tighter than traditional manual measurement, which carries a tolerance of ±1–3 inches (Robotic Imaging, 2026). A hospital Scan to BIM project costing $45,000 identified coordination conflicts that would have cost $180,000 to resolve during construction — a 4x return on the scanning investment (iScano, 2025). In 2026, Scan to BIM pricing for standard commercial spaces at LOD 300 ranges from $0.50–$2.10 per sq ft, rising to $2.00–$10.00+ per sq ft for dense MEP environments like data centres and hospitals.
For architects, engineers, and contractors across the USA, Scan to BIM has become the standard approach for existing building documentation. Traditional manual measurement — tape measures, total stations, and 2D CAD drafting — cannot match the accuracy, speed, or completeness of modern terrestrial laser scanning. A single scan session captures millions of precise data points that represent every surface condition in the building, including hidden MEP systems, structural elements, and spatial geometry that cannot be reliably measured by hand.
At Excelize, we have been delivering Scan to BIM modeling services since 2003. Our point cloud processing and BIM modeling team works with all major point cloud file formats (.RCP, .RCS, .E57, .FLS, .PTG, .OBJ, .PCG, .XYZ) from every leading laser scanner brand — Leica, FARO, Trimble, Riegl, and Matterport. We produce as-built Revit models at LOD 200–500 for renovation, retrofit, heritage documentation, MEP coordination, and facility management handover across all building types and sectors in the USA.
±2–4mm scan accuracy vs ±1–3 inch manual measurement. $45,000 scan → $180,000 rework prevented. LOD 300 commercial modeling: $0.50–$2.10/sqft.
Watch our technical walkthroughs showing how we convert raw laser scan data (point clouds) into highly accurate, clash-free LOD 300-400 Revit models for complex MEP, architectural, and structural renovation projects.
"Excelize's Scan to BIM methodology goes beyond simple tracing. We build intelligent, parametric Revit families directly over the point cloud data, ensuring the final as-built model is fully actionable for engineering design, clash detection, and facility management."
We deliver models with Level of Accuracy (LOA) up to ±1-5mm, critical for mechanical pump rooms, industrial process piping, and heritage conservation.
Pipes, ducts, and conduits are not just solid geometry; they are connected, system-assigned MEP elements ready for pressure drop analysis and routing updates.
Every delivered project includes a point cloud vs. model deviation heat map to verify that our Revit geometry perfectly matches the real-world scan data.

Excelize delivers a complete range of scan-based modeling services — from full as-built BIM models to 2D CAD as-built drawings, parametric Revit families from scanned objects, and mesh generation for digital twin applications.
Our core service — converting laser scan point cloud data into fully coordinated, intelligent 3D BIM models in Autodesk Revit. We produce as-built architectural, structural, and MEP Revit models at LOD 200–500 from point cloud data. All models are parametric, data-rich, and suitable for renovation design coordination, clash detection, shop drawing production, and facility management handover.
Converting point cloud data into 2D as-built drawings in AutoCAD (.DWG format). This service is suited for projects requiring basic as-built documentation without parametric BIM intelligence — including simple residential renovations, retail fit-outs, and planning application drawings. We produce accurate 2D floor plans, sections, elevations, and site layouts from the point cloud.
Creating parametric Revit families (BIM objects) from scanned physical objects — unique equipment, custom architectural elements, heritage fixtures, or building products that do not exist in standard Revit libraries. We scan the physical object, process the point cloud, and produce a parametric Revit family with accurate geometry and data parameters for use in your project model.
Generating a 3D surface mesh from point cloud data for digital twin, visualization, virtual reality, or computational analysis applications. Scan to Mesh is used when a lightweight 3D representation is needed without the full parametric intelligence of a BIM model — for example, for Matterport-style virtual tours, photorealistic rendering, or computational fluid dynamics (CFD) analysis.

Send Us Your Point Cloud Data for a Free Sample Conversion
Any format, any scanner brand — we handle all processing. No pre-conversion required on your end.
Our structured Scan to BIM workflow ensures that every point cloud is processed with engineering precision — from raw scan registration through to quality-verified, LOD-compliant BIM deliverables your team can use immediately.
Project Scoping & Requirements
We review your project requirements, define the delivery scope — LOD level, disciplines required, file formats, coordinate system, and intended use (renovation design, FM handover, MEP coordination, or prefabrication) — before processing begins. This step prevents expensive scope changes mid-project.
Scope confirmation, LOD specification, coordinate system agreement
Point Cloud Data Receipt & Validation
We receive your point cloud files in any supported format (.RCP, .E57, .FLS, .PTG, etc.) and validate data completeness, scan coverage, and quality. We identify any gaps in scan coverage, misaligned scan positions, or data corruption before proceeding to processing.
Data quality report, coverage gap identification, scan registration assessment
Point Cloud Processing & Registration
Raw scan data is cleaned, de-noised, and registered — aligning multiple scan positions into a single unified, coordinate-referenced point cloud. We use Autodesk ReCap Pro, FARO Scene, and Leica Cyclone for scan registration, achieving sub-millimeter alignment across scan positions.
Registered point cloud (.RCP file), scan registration report, accuracy verification
BIM Model Development from Point Cloud
Our BIM modeling team uses the registered point cloud as reference geometry to build parametric architectural, structural, and MEP Revit models. Every element is traced from the point cloud and modeled as an intelligent Revit element with data attributes at the agreed LOD standard.
Discipline Revit models (.RVT) at agreed LOD, milestone model checkpoints
Quality Control & Accuracy Verification
Every Scan to BIM model undergoes a rigorous QC process. We verify model elements against the point cloud reference at multiple locations using deviation heat-map analysis. Geometric accuracy is confirmed against the USIBD Level of Accuracy (LOA) standard before client delivery.
QC report with accuracy verification, deviation analysis, model completeness checklist
Delivery & Post-Delivery Support
Final Revit models are delivered with transmittals in all agreed formats — Revit (.RVT), IFC, NWD (for Navisworks), and 2D PDF drawing sets. Post-delivery support is provided for any questions, model queries, or minor updates during the design and construction phases.

Professional Scan to BIM services are defined not just by the LOD of the model, but by the spatial accuracy of the point cloud from which the model is built. The US Institute of Building Documentation (USIBD) Level of Accuracy (LOA) framework is the industry standard for specifying and verifying Scan to BIM accuracy.
// USIBD Level of Accuracy (LOA) Framework| LOA Level | Spatial Tolerance | Application |
|---|---|---|
| LOA 10 | Approximate (±5cm+) | Conceptual design, feasibility studies, visual reference only. Not suitable for engineering design or construction coordination. |
| LOA 20 | 15mm – 5cm | General planning, architectural design development, space planning. Not suitable for MEP coordination or fabrication. |
| LOA 30 ★ | 5mm – 15mm | Standard for most renovation and retrofit design projects. Sufficient for architectural and structural coordination in Revit. Excelize standard delivery. |
| LOA 40 ★ | 1mm – 5mm | Engineering-grade accuracy for MEP coordination, curtain wall systems, prefabrication, and heritage conservation. Requires high-end scanner (Leica, FARO). Available on request. |
| LOA 50 | ≤ 1mm | Forensic documentation, precision manufacturing, and industrial plant documentation. Requires specialized equipment and methodology. |
Most Scan to BIM projects for renovation, retrofit, and facility management require LOA 30 (±5–15mm). MEP coordination, prefabrication, and curtain wall projects require LOA 40 (±1–5mm). Excelize's standard Scan to BIM workflow achieves LOA 30 accuracy using FARO and Leica scanners, with LOA 40 available for projects requiring engineering-grade precision. Every deliverable includes an accuracy verification report confirming achieved LOA against the project specification.
| Parameter | Traditional Surveying | Scan to BIM |
|---|---|---|
| Spatial accuracy | ±1–3 inches (tape measure) / ±5–15mm (total station) | ±2–4mm (terrestrial LiDAR) — 10x tighter than manual methods |
| Measurement coverage | Spot measurements at defined points only | Millions of data points capturing every surface continuously |
| Hidden conditions | Cannot capture concealed MEP without destructive opening | Visible MEP systems captured completely; hidden elements flagged |
| Return site visits | Frequently required when design discovers unmeasured conditions | Complete point cloud eliminates return visits — all surfaces queryable |
| Deliverable format | 2D CAD only | 2D CAD + 3D BIM + IFC + NWD from a single field capture |

Every Excelize Scan to BIM deliverable includes a USIBD LOA verification report. Tell us your accuracy requirement — we'll confirm achievable LOA for your scanner data.
Scan to BIM is applicable across every sector where existing building conditions need to be accurately documented before design, renovation, or construction begins. Here are the primary use cases where Excelize delivers Scan to BIM services.
Renovation projects fail when as-built drawings are inaccurate or unavailable. Laser scanning captures the exact existing conditions — wall thicknesses, column locations, ceiling heights, MEP routing — so that renovation designs coordinate correctly with what is actually there, not what the original drawings said was there. Scan to BIM for renovation eliminates the most common cause of renovation project cost overruns: field conditions that don't match design assumptions.
Historic and heritage buildings have no reliable as-built drawings, highly irregular geometry, and material conditions that cannot be measured accurately by hand. Scan to BIM is the only methodology that captures heritage buildings with the accuracy required for conservation design, planning compliance, and structural assessment. LOA 40 scanning using Leica or FARO equipment achieves the millimeter-level accuracy required for conservation-grade documentation.
Building owners use LOD 500 Scan to BIM models for ongoing facility management — tracking asset locations, planning maintenance operations, managing space, and integrating with CAFM (Computer-Aided Facilities Management) systems. Scan to BIM from a building's existing conditions creates a reliable digital twin baseline when original design BIM models do not exist or are not current.
MEP systems in existing buildings are rarely documented accurately in 2D drawings. Scan to BIM captures the as-built MEP routing — duct positions, pipe locations, equipment placement, and clearances — enabling renovation and upgrade designs to coordinate correctly with existing systems. LOD 350–400 MEP Scan to BIM provides the detail needed for pre-fabrication and MEP trade coordination on complex retrofit projects.
Bridges, tunnels, roads, and utilities require high-accuracy as-built documentation for inspection, maintenance, and expansion design. LiDAR scanning from terrestrial, mobile mapping, and drone platforms captures infrastructure geometry at the scale and accuracy required for civil engineering BIM. We use LiDAR point cloud data from mobile mapping systems (NavVis, FARO) and aerial drones to produce infrastructure BIM models in Revit and Civil 3D.
Scan to BIM is increasingly used during construction — not just for documentation of existing buildings. Regular scan-and-compare workflows verify that structural elements, MEP installations, and architectural finishes are being constructed within tolerance. Point cloud vs BIM model deviation analysis identifies construction errors before they are covered up, eliminating the cost of rework and defect rectification after handover.

Scan to BIM pricing has two components: laser scanning (field capture) and BIM modeling (office processing). Costs vary based on project size, complexity, LOD level, number of disciplines, and number of coordination cycles required. Contact us for a project-specific quote within 24 hours.
Scan to BIM pricing has two components: laser scanning (field capture) and BIM modeling (office processing). Scanning costs depend on crew size, equipment type, and site complexity. BIM modeling costs vary by floor area, LOD level, number of disciplines, and model complexity. Most commercial projects are delivered in 10–14 business days.
Professional laser scanning is priced per day, based on equipment type, crew size, site accessibility, and scanner resolution requirements. High-accuracy LOA 40 scanning with Leica or FARO survey-grade equipment commands a premium over standard LOA 30 scanning. Matterport interior scanning for simple residential or retail spaces is the most cost-effective option. Contact us if you already have your point cloud data — we can model from any scan you supply, reducing your cost to BIM modeling only.
BIM modeling from point cloud data is priced per square foot, based on LOD level, number of disciplines (architectural, structural, MEP), and model complexity. Dense MEP environments like hospitals and data centres require significantly more modeling time per square foot than simple commercial spaces. Heritage and conservation projects with irregular geometry and high LOA requirements carry a premium.
| Project Type / LOD | Typical Turnaround |
|---|---|
| Small residential (LOD 300, <5,000 sqft) | 5–7 business days |
| Commercial office (LOD 300, 10,000–50,000 sqft) | 10–14 business days |
| Industrial / warehouse (LOD 300, basic MEP) | 2–3 weeks |
| Heritage / historic building (LOD 400, high accuracy) | 3–6 weeks |
| Hospital / data centre (LOD 350–400, dense MEP) | 4–8 weeks |
| Infrastructure (LiDAR, bridge, tunnel) | 2–6 weeks depending on scope |
| Point cloud modeling only (client supplies scan) | 5–10 business days |
Higher LOD = more modeling time. LOD 200 is the fastest; LOD 400–500 requires element-by-element parametric modeling from the point cloud.
Architectural only vs full Arch + Structural + MEP significantly impacts scope and cost.
Dense MEP environments (hospitals, data centres, industrial plants) require far more modeling time per square foot than open commercial spaces.
Well-registered, clean point cloud data from a professional scanning crew reduces processing and modeling time significantly versus low-quality or incomplete scan data.
LOA 40 engineering-grade accuracy requires premium scanner equipment and more rigorous registration methodology versus standard LOA 30 scanning.
Additional deliverables beyond standard Revit (.RVT) — IFC, NWD, 2D PDF sets, COBie data — add scope but are included in our standard project package.
If you already have your laser scan data from your own scanner or a scanning contractor, you only pay for BIM modeling (Component 2). Send us your point cloud files in any supported format (.RCP, .E57, .FLS, .PTG, etc.) and we will return a firm quote within 24 hours.
