As-Built BIM Modeling Services

LOD 500 represents the highest level of development in BIM models. It is a record model that precisely documents the as-constructed geometry and attributes of every building component. LOD 500 models are verified against site conditions and are used for facility management, asset tracking, and building handover. Unlike LOD 200–400 models, LOD 500 models include asset data and are delivered with COBie information for FM system integration.

Point cloud to BIM modeling focuses on converting scan data into a Revit model at LOD 200–400 for design development, coordination, or fabrication. As-built BIM modeling specifically targets LOD 500 — the post-construction record model — and includes COBie asset data for FM handover and CAFM system integration. As-built BIM models are the deliverable required for building handover and ongoing facility management.

COBie (Construction Operations Building Information Exchange) is a standardized format for capturing asset data required for facility management. It includes manufacturer details, warranty information, maintenance schedules, and performance specifications. COBie data is critical for FM system integration and efficient building operations. Many government and institutional clients now require COBie data as part of project handover.

We work with a range of source data depending on your project requirements: Laser scan data (E57, RCP, LAS formats), Site photographs for material and detail reference, Marked-up drawings (PDF, DWG), and Existing CAD files and design models. If your project does not include scan data, we can model from marked-up drawings and site photos, or coordinate with your survey team for additional verification.

Project timelines vary based on building size, complexity, and source data quality. Typical project durations: Small building (up to 2,000m²): 2–3 weeks; Medium building (2,000–10,000m²): 3–5 weeks; Large building (10,000m²+): 5–8 weeks. We provide a project-specific schedule with every quote. For urgent projects, expedited delivery may be available.

Standard deliverables include: Native Revit model (.RVT), IFC export (IFC 2x3 or IFC 4), COBie data (.XLSX), and Navisworks cache file (.NWC). Additional deliverables — including AutoCAD DWG exports, PDF drawing sheets, and asset data exports — are available on request.

Yes. We deliver COBie data in formats compatible with leading CAFM and CMMS platforms. If you are using a specific FM system, please let us know and we can align the COBie data format with your requirements.

Yes. We deliver complete, federated as-built BIM models covering Architectural, Structural, and MEP disciplines within a single coordinated Revit environment. All disciplines are modeled to LOD 500 and verified against source data.

Yes, for projects where scan data is not available. However, the accuracy of a model built from drawings is limited by the accuracy of those drawings. Where drawings are outdated or incomplete, we recommend complementing them with scan data or site verification for the most accurate result. Our team can advise on the most suitable approach for your project.

Yes. Our heritage and historic building BIM service specialises in modeling complex, irregular, and non-standard historic geometry. We work with scan data to capture the unique fabric of listed buildings and conservation properties.
