Scan to BIM in Westminster: Costs, Deliverables and Turnaround
Scan to BIM projects in Westminster (postcodes W1, W2, WC1, WC2, NW1, SW1) capture point cloud data with terrestrial laser scanners, then model the building in Revit or ArchiCAD for downstream design, BIM coordination, and facility management. The process produces a 3D digital twin of the existing building that downstream architects, MEP engineers, and structural engineers can use as the basis for design and coordination.
Standards and Accuracy
Scan to BIM projects in Westminster follow the RICS Measured Surveys of Land, Buildings and Utilities (3rd edition) and BS EN ISO 19650-2:2018 for BIM execution. Point cloud capture typically achieves plus or minus 3-6 mm accuracy at 10-25 m range with a FARO Focus or Leica RTC360 scanner. Modelling accuracy to plus or minus 15 mm of the point cloud is typical for LOD 350 deliverables per the BIMForum LOD Specification.
Deliverables
Standard deliverables for a Scan to BIM project in Westminster include:
- Point cloud (E57 or RCP) at full scanner resolution
- Revit model (RVT 2022 or current) at LOD 300 / LOD 350
- IFC export for downstream coordination (Navisworks, Solibri)
- Existing plans (DWG) and existing elevations
- Signed accuracy statement per RICS Measured Surveys standard
Typical Costs
Scan to BIM costs in Westminster depend on site size, scanner time, and deliverable set:
- Small site (single day scan): 3,000 to 10,000+ pounds ex VAT per day
- Medium site (2-3 day scan + processing): typically 3,000-2,500 pounds ex VAT per day plus modelling
- Large site (multi-day scan + BIM): 3,000-10,000+ pounds ex VAT total
When to Commission
Scan to BIM is typically commissioned by BIM managers, architects, MEP engineers, and heritage consultants for:
- Existing conditions recording for design or refurbishment
- Heritage recording for listed building consent
- BIM coordination and clash detection
- As-built verification
- Planning applications requiring accurate elevations
How to Commission
To commission scan to bim in Westminster, prepare a brief covering the site address, the project type, the required deliverables (point cloud only, or with modelling), and the target accuracy. Submit the brief via the icelabz quote form for a fixed-fee quote within 24 hours, with site work typically commencing within 5-10 working days of instruction.
