3D Laser Scanning Surveys, As-Built and Measured Building Services for Construction and Architecture
SCANM2 provides professional 3D laser scanning and as-built survey services for construction and architecture projects.
Using advanced LiDAR and terrestrial laser scanning systems, we capture millions of spatial data points to produce accurate as-built documentation, CAD drawings, and BIM-ready models.
Our precise digital surveys help architects, engineers, and contractors eliminate uncertainty, reduce costs, and make informed design and construction decisions.
What Is a 3D Laser Scanning Survey?
A 3D laser scanning survey captures millions of points in three-dimensional space, forming a detailed digital representation — or point cloud — of any structure.
This data provides an exact record of real-world conditions, allowing precise analysis and integration into CAD and BIM environments.
Key advantages:
- Exceptional measurement accuracy (up to ±2 mm);
- Safe, contactless data collection;
- Rapid scanning of complex or inaccessible areas;
- Reliable foundation for architectural and engineering documentation.
📊 According to Trimble’s Geospatial Report 2025, 3D laser scanning reduces on-site measurement time by up to 70% and improves accuracy by more than 90% compared to traditional methods.
Applications of 3D Laser Scanning
3D Laser Scanning Services for Construction Projects
In construction, 3D laser scanning ensures accuracy at every project stage — from initial site surveys to final as-built documentation.
Contractors use it for BIM verification, clash detection, and progress monitoring, preventing costly design deviations and minimizing rework.
| Application | Result |
| Structural verification | Early detection of deviations |
| As-built documentation | Certified digital record of the site |
| BIM coordination | Seamless comparison between model and reality |
| Progress monitoring | Accurate visual tracking of construction stages |
Architectural 3D Laser Scanning Services
For architects and designers, architectural 3D scanning services deliver reliable geometry for both new and historic structures.
Data obtained through scanning supports measured building surveys, detailed façade modeling, and heritage restoration projects.
Every architectural element — from ornate details to full interiors — can be accurately captured and integrated into Revit or ArchiCAD.
3D Laser Scanning Services for Restoration and Heritage Projects
3D laser scanning is invaluable in restoration and heritage documentation, offering a non-invasive way to preserve and reproduce architectural features.
It allows conservation experts to document fragile façades, model complex ornamentation, and archive historic buildings digitally for future generations.
Measured Building and As-Built Surveys
Measured building surveys document the existing condition of structures before design or renovation, while as-built surveys verify the completed work after construction.
Both are crucial for precision, regulatory compliance, and long-term asset management.
Deliverables include:
- 2D CAD drawings (plans, elevations, sections);
- 3D Revit / ArchiCAD models (LOD 200–400);
- Point clouds in RCP, E57, or LAS format;
- BIM-ready documentation for architects and engineers.
| Type of Survey | When Conducted | Primary Purpose |
| Measured Building Survey | Before design | Base for planning and renovation |
| As-Built Survey | After construction | Verification and handover documentation |
ScanM2 performs both survey types in full compliance with RICS and ISO 17123 accuracy standards.
Workflow and Deliverables
Our workflow covers every stage of project documentation:
- On-site scanning – data capture using Leica, Trimble, or FARO laser systems.
- Point cloud processing – cleaning, alignment, and registration.
- CAD/BIM modeling – creating accurate Revit, AutoCAD, or IFC deliverables.
- Quality assurance – verification, error analysis, and secure data delivery.
Output formats: RCP, E57, DWG, DXF, RVT, IFC, PDF.
ScanM2 transforms real-world data into high-accuracy 3D models and documentation tailored to each client’s workflow — architectural, structural, or MEP.

FAQ
What is the difference between a measured building survey and an as-built survey?
A measured survey documents the existing conditions of a building before design or renovation, while an as-built survey records the final constructed state to verify compliance and produce official documentation.
How accurate is 3D laser scanning?
3D laser scanning can achieve accuracy of up to ±2 mm, depending on the equipment, environment, and size of the project area.
What file formats can you deliver?
SCANM2 provides deliverables in all major industry formats — Revit (RVT), AutoCAD (DWG, DXF), IFC, and point cloud files (RCP, E57, LAS) for seamless integration into your design workflow.
How long does a 3D laser scanning project take?
Project duration depends on site size and complexity.
For example, scanning a medium-sized building (up to 2,000 m²) typically takes 1–2 days on site, with 3–5 days for processing and modeling.
Can 3D laser scanning be used for heritage or historical buildings?
Absolutely. Laser scanning is ideal for heritage documentation, restoration, and conservation projects.
It allows safe, non-contact data capture from fragile or inaccessible areas without disturbing the original materials.
What are the main benefits of using 3D laser scanning over traditional surveying?
Compared to manual surveying, laser scanning offers:
-
Up to 10x faster data collection;
-
Higher accuracy and completeness;
-
Safer data capture from a distance;
-
Comprehensive digital record for reuse in BIM or CAD.
How is the scanned data processed and delivered?
After scanning, the point cloud is cleaned, registered, and aligned.
Then SCANM2’s specialists create 2D CAD drawings, 3D BIM models, or IFC datasets, depending on your project requirements.
All deliverables go through internal QA/QC verification before delivery.
What industries can benefit from 3D laser scanning?
3D laser scanning is widely used in:
-
Architecture and interior design;
-
Construction and civil engineering;
-
Industrial facilities and energy plants;
-
