3D laser scanner capturing point cloud data inside a building transformed into an as-built 3D Revit BIM model showing architectural and MEP coordination BIM service

About This Service

Scan to BIM Services

When you're working on a renovation, retrofit or any project involving an existing building, accurate as-built information is the starting point for everything. Old drawings are often out of date. Site measurements miss detail. Assumptions made early create problems later when walls don't land where the model says they should.

Scan to BIM Services solve this by turning laser scan data point clouds captured on site into a precise, usable Revit model. Our team at Eminent BIM Services takes your raw scan files, processes them against the building geometry, and produces models and drawings that reflect actual site conditions. What you get is a reliable foundation for design, coordination, and construction documentation built from what's physically there, not what the original drawings assumed.

What Is Scan to BIM?

Laser scanning captures a building or site as millions of measured points in three-dimensional space a point cloud. The scan records walls, floors, ceilings, columns, ductwork, and any other visible element with sub-millimetre precision. That data on its own is not a model; it's a dense geometric record of real-world conditions.

Scan to BIM is the process of converting that point cloud into a structured Revit model. A BIM modeller works inside the point cloud, tracing and placing model elements to match what the scan shows a wall at exactly this thickness, a beam at this elevation, a duct at this offset from the ceiling. The result is a model that reflects existing conditions rather than design intent, which is exactly what renovation, retrofit and refurbishment projects need.

Point cloud data can come from terrestrial laser scanners, handheld devices, or drone-mounted LiDAR. The format doesn't change the modelling process much. What matters is scan coverage, registration quality, and the agreed accuracy tolerance for the project.


Our Scan to BIM Scope


Point Cloud Review and Registration Checks

Before any modelling starts, we review the point cloud files for coverage gaps, registration errors, and scan density. If ceiling areas weren't captured, or if a corridor has sparse data, we flag it before modelling begins not after the client notices missing elements in the model.

Architectural Scan to BIM

We model walls, floors, ceilings, doors, windows, stairs, columns, beams, and architectural finishes from the scan data. Existing condition BIM modelling at this level gives architects and designers accurate floor plans, sections, and elevations to work from without a return site visit every time a dimension is needed.

Structural Scan to BIM

Structural elements columns, beams, slabs, shear walls are modelled with the geometry visible in the scan. This is particularly useful when structural drawings for an older building don't exist or can't be trusted. We model what the scan shows, at the accuracy tolerance agreed at project start.

MEP Scan to BIM

Visible MEP elements ductwork, pipework, cable trays, plant equipment are modelled as they appear in the scan. Hidden elements inside shafts, above closed ceilings, or behind cladding cannot be modelled from scan data alone, and we're upfront about that. What's captured is modelled; what isn't captured is noted.

Model Updates and Revision Support

Scan data captured at different project stages can be used to update the model as work progresses. We can also integrate scan-derived geometry with design models for clash checking and coordination.

What We Deliver

  • Our standard deliverables for Scan to BIM projects include:
  • Revit as-built model (.rvt), structured by discipline and level
  • Floor plans, reflected ceiling plans, sections, and elevations
  • 3D views and walkthroughs for design review
  • Deviation analysis notes where scan coverage affects modelling accuracy
  • Exported drawings in PDF and DWG formats
  • Navisworks federated model where coordination is in scope
Files are delivered via shared cloud folders (Autodesk Construction Cloud or client-specified platform). We work to the client's BIM Execution Plan, layer naming conventions and title block templates where these are provided.

Our Workflow

  1. Receive and review client files: We take the point cloud files (.rcp, .e57, .las), any existing drawings, and the project brief. We confirm scan coverage and flag gaps before modelling starts.
  2. Agree modelling scope and tolerance: We confirm which disciplines are in scope, the target LOD, and the accuracy tolerance (typically ±6mm to ±25mm depending on building type and project use).
  3. Point cloud registration check: If the scan has been supplied pre-registered, we verify that registration is clean. Misaligned scans produce misaligned models, so this step matters.
  4. BIM model setup: We set up the Revit project with the correct grid, levels, and shared coordinates, aligned to the point cloud.
  5. Model development: Modellers work discipline by discipline through the point cloud, placing elements to match scan geometry. We work to the agreed scope - we don't model what wasn't captured.
  6. Internal quality check: A senior modeller reviews the model against the point cloud for accuracy, consistency, and completeness before it leaves the team.
  7. Client review: We issue the model and drawings for client review, with a clear list of areas where scan coverage was limited.
  8. Revisions: We address review comments, update elements, and recheck affected areas.
  9. Final delivery: Issued in agreed formats, with a brief model note covering LOD achieved, coverage gaps, and any assumptions made.


Level of Development (LOD)

LOD describes how much geometric detail and spatial accuracy a model carries. For Scan to BIM work, the LOD achieved depends directly on what the scan captured and what the project requires.

LOD 200 gives approximate geometry walls at their correct general location and thickness, major structural elements in position. This is enough for early-stage feasibility studies or space planning on existing buildings where rough accuracy is acceptable.

LOD 300 gives accurate geometry and location, suitable for construction documentation, design coordination, and permit drawings. Walls are modelled to their actual measured thickness and position. Door and window openings are sized and located to match the scan. This is the level most renovation and retrofit projects work to, and it's our typical delivery standard for Scan to BIM Modeling Services.

LOD 350 adds connection and interface detail where a duct penetrates a wall, how a beam connects to a column. We deliver this where coordination between disciplines is a project requirement and the scan data supports it.

For MEP elements captured in a scan, we typically work to LOD 200 or 300 depending on duct and pipe clarity in the point cloud. It's worth noting that LOD covers geometry; LOI (Level of Information) covers data and parameters. If asset data, equipment tags, or COBie output are needed alongside the model, we scope that separately.

Software We Use

  • Autodesk Revit: the core modelling environment for all Scan to BIM work. All discipline models are built in Revit and issued as .rvt files.
  • Autodesk ReCap: for point cloud processing, registration review, and preparing scan files for use inside Revit.
  • Navisworks: for federating discipline models, running coordination checks, and producing combined 3D views where multiple disciplines are in scope.
  • AutoCAD: for 2D drawing production and export where clients need DWG deliverables alongside Revit files.

Why Clients Use This Service

The most straightforward reason: existing building drawings are rarely accurate enough to design from. A building put up in the 1970s may have been modified multiple times. The drawings on file may not reflect any of those changes. Starting a renovation design on that basis creates risk at every stage from setting out to services coordination to procurement.

Point Cloud to BIM Services give the design team a model they can trust. Architects can extract accurate floor plans without measuring every room. Structural engineers can see actual column positions and beam sizes. MEP designers can route new services around existing ductwork without guessing what's above the ceiling.

For retrofit projects, Scan to BIM for Existing Buildings reduces the back-and-forth between site and design office. Clashes between new and existing elements are caught in the model rather than on site. Quantities extracted from the model are based on actual conditions rather than assumptions. Coordination between disciplines starts from a shared, accurate picture of what's there.

It also helps with client communication. A model that visitors can navigate in 3D explains existing site conditions more clearly than a stack of old drawings.


Projects We Support

  1. Renovation and refurbishment - office fit-outs, residential conversions, heritage buildings where original drawings are incomplete or missing. Scan to BIM for Renovation gives the project team a verified starting point and avoids costly surprises during construction.
  2. Retrofit and MEP upgrades - hospitals, data centres and industrial facilities upgrading mechanical, electrical and plumbing services within occupied or live buildings. Modelling existing conditions before design work begins keeps clash risk low.
  3. Commercial and mixed-use - retail centres, hotels and office towers where accurate floor areas and column grids are needed for leasing, planning or repositioning.
  4. Educational and institutional - universities and public buildings with long build histories and inconsistent drawing records. Existing Condition BIM Modeling brings order to complex as-built situations.
  5. Infrastructure-related buildings - plant rooms, substations, and technical facilities where services density is high and spatial accuracy is critical for any modification work.

Why Work With Eminent BIM Services?


Our team works on Scan to BIM projects across the UK, US, Middle East, Australia and other markets. We understand that different clients come to this service with different starting points some provide clean, fully registered scan data; others hand over files captured by a third-party surveyor that need careful review before modelling begins. Either way, we scope the work based on what's actually in the data.

We work to client BIM standards BEP requirements, naming conventions, shared coordinate systems, title blocks and we flag deviations before they become problems. Quality checking is built into the workflow, not added at the end. The model that leaves our team has been reviewed against the point cloud by someone who didn't build it.

As a Scan to BIM Company in India, we offer a practical cost advantage for international clients without compromising on technical output. Turnaround times are discussed at project start and held to. Files are exchanged through secure shared platforms and backed up at each stage.

We don't oversell what scan data can deliver. If a section of the scan is sparse or an area wasn't captured, we say so in the model notes and on the drawings. Clients get a clear record of what was modelled, at what accuracy, and where limitations apply.

Work With Our Team

If you have point cloud data from a laser scan and need a Revit model built from it, send us the scan files along with any drawings or project notes you have. Our team will review the data, confirm what we can model and to what accuracy, and discuss scope and timeline with you before any work begins. We're straightforward about what the data supports and what it doesn't.

FAQ
Scan to BIM improves design accuracy, reduces site visits, supports renovation projects, enhances collaboration, and creates reliable digital representations of existing buildings.
We need the point cloud files in .rcp, .e57 or .las format, along with any existing drawings or PDFs that help us understand the building layout. Photos of complex areas are useful but not essential. If you have a BIM Execution Plan or BEP, share that too and we'll work to your standards.
Most projects are delivered at LOD 300, which covers accurate geometry and location suitable for design and documentation. We can work to LOD 200 for early-stage work or LOD 350 where connection and interface detail is needed. MEP elements visible in the scan are typically LOD 200–300 depending on point cloud clarity.
We model MEP elements that are visible and clearly resolved in the scan exposed ductwork, pipework, cable trays, major equipment. Elements hidden above closed ceilings, inside service shafts or behind cladding cannot be modelled from scan data, and we document those gaps in the model notes.
We work with point cloud files in standard formats (.rcp, .e57, .las, .laz) regardless of which scanner was used to capture them. We process the files in Autodesk ReCap and import them into Revit.
We work with pre-registered point clouds. If your scan files arrive unregistered, we'll flag this at the file review stage. Registration itself combining individual scan positions into a unified coordinate system requires specialist survey software and is typically done by the surveying team before handover.
Yes. Federating the as-built model with new design models in Navisworks is within our scope where coordination is included. We can run clash checks between existing and proposed elements and produce clash reports for design review.
We can work within an ISO 19650 workflow and structure deliverables accordingly. We also work to UK (BS EN ISO 19650), US, Middle East, and Australian BIM standards based on project requirements.
It depends on building size, scan coverage, number of disciplines, and LOD. A single-floor commercial space at LOD 300 might take five to eight working days; a multi-storey mixed-use building takes longer. We give a timeline at the scoping stage and flag anything that would affect it.
