What Is a 3D Laser Scanning Survey?

A 3D laser scanning survey captures a building, structure or site as a dense cloud of measured points, each one located in 3D space to within a millimetre. A FARO laser scanner sweeps every visible surface from each setup position, recording millions of points per second. We move the scanner through the building, registering each scan to a unified coordinate system, until every space the brief requires has been captured.

The output is a registered point cloud. From that point cloud we then deliver whatever your project actually needs: a Revit BIM model, 2D CAD plans and elevations, a clash-detection deliverable, a mesh model, or just the raw cloud handed over for your own team to work with.

Who We Work For

  • Architects working on refurbishments, extensions, change-of-use and heritage projects who need a verified existing-conditions model to design against.
  • Structural engineers needing accurate as-built geometry to inform retrofit, strengthening or change-of-use design.
  • MEP consultants working in plant rooms, riser shafts and complex services environments where measured survey alone will not capture the density of information required.
  • Main contractors and design-and-build teams who need scan-verified as-builts for handover, clash detection or progress monitoring.
  • Heritage consultants and conservation architects working on listed buildings, where every detail matters and intervention must be justified.

Our Deliverables

This is what makes 3D laser scanning different from a traditional measured survey: you are not limited to one output. We deliver any combination of the following from a single scan dataset.

A unified point cloud delivered in your preferred format. We routinely supply RCP and RCS for Revit and Navisworks workflows, E57 for cross-platform compatibility, FLS for FARO Scene users, and PTS or PTX for legacy CAD environments. See our guide to point clouds formats and our RCP point cloud explainer for the technical detail.

A Revit model built directly from the point cloud, modelled to your specified Level of Detail. We typically deliver LOD 200 for early-stage design intent, LOD 300 for coordination and tender, and LOD 350 to 400 where elements need to be fabrication-ready. Architectural, structural and MEP disciplines all available, separately or as a federated model. See our scan to BIM for MEP page for plant room and services-specific work.

2D plans, sections and elevations produced from the scan data. AutoCAD DWG, layered to your office standard. This is often the right choice when you want measured-survey-style drawings but the building is too complex, too tall, or too restricted-access to survey conventionally.

Textured mesh models for visualisation, fly-throughs, or import into Rhino, SketchUp or 3ds Max. Useful for client presentations, planning submissions and heritage documentation.

Comparison of as-built scan data against design intent. Useful at handover (verifying installed services match the design model), or partway through a build to catch clashes before they become rework.

When to Use Laser Scanning Instead of a Traditional Measured Survey

A fair question, and one we get from architects regularly. Both services can deliver plans and elevations. The right choice depends on what else you need.

Choose laser scanning when any of the following apply:

  • The building is complex or dense (heavily serviced plant rooms, heritage interiors, irregular geometry).
  • The project will be coordinated in Revit or another BIM environment, and you want a model rather than just drawings.
  • You want the raw point cloud archived for future use, future design rounds, or to share with structural and MEP consultants working in parallel.
  • Access is restricted, the building is occupied, or the survey window is short. Scanning is dramatically faster on site than tape-and-laser-distance methods.
  • You are doing clash detection, verification or as-built capture against a design model.

Choose a traditional measured survey when:

  • You need standard architectural drawings (plans, elevations, sections, reflected ceiling plans) and nothing more.
  • The building is straightforward and the cost of a full scan dataset is not justified.
  • You do not have a downstream BIM workflow.

Honest answer: for most modern AEC projects with any BIM involvement, 3D laser scanning is now the better starting point even if the eventual deliverable is just 2D drawings. The cost difference at our end is smaller than it used to be, and you keep the option to revisit the cloud later.

Equipment and Accuracy

We scan with the FARO Focus range. Stated accuracy is plus or minus 2mm at 25m, captured at up to two million points per second. Each scan position takes 3 to 8 minutes depending on the resolution setting.

Registration is performed in FARO Scene to a target-and-cloud-to-cloud workflow, with registration error typically under 3mm across an entire building.

For sites that need geo-referencing, we tie the scan network to OS National Grid or to a project grid using GNSS or total station observations.

Our Process

  1. Brief and quote. Send us drawings, an address, or a sketch of the area to scan, and tell us the deliverable you need (point cloud only, Revit at LOD 300, scan-to-CAD plans, etc). Quote returned within one working day.

  2. Site visit and scanning. Our surveyor scans every required space at the appropriate resolution. Most residential or small commercial projects are completed in a single day. Larger or more complex sites take 2 to 5 days.

  3. Registration and QA. Scans are registered in FARO Scene and quality-checked against the agreed accuracy specification.

  4. Modelling or drafting. If you have requested BIM or CAD output, our in-house team builds the model or drawings from the registered cloud.

  5. Files delivered by secure OneDrive link, typically within 7 to 14 working days of the final scan visit, depending on deliverable complexity. Point cloud only deliveries are usually within 5 working days.

Pricing

Survey scope and deliverables vary too much for a one-size price, but as a rough guide:

  • Point cloud only, small London building (one to three storeys, up to 500 sqm GIA): from around £1,200 plus VAT.
  • Scan plus 2D CAD (plans, sections, elevations) of the same: from around £1,000 plus VAT.
  • Scan to BIM at LOD 300, architectural model only, same building: from around £1,250 plus VAT.
  • MEP scan to BIM, federated architectural plus services model: priced per project, typically from £2,000 plus VAT.

We are happy to quote against a specification or work to a fixed deliverable list.

FAQ's - 3D Laser Scanning

Both can produce 2D plans and elevations. A laser scan additionally produces a point cloud (a millimetre-accurate 3D record of the entire building) which can be reused later for BIM modelling, clash detection, fly-throughs or further design rounds. If the project has any BIM involvement, or if the building is complex or services-heavy, scanning is usually the right choice. For straightforward 2D architectural drawings on a simple building, a traditional measured survey is often more cost-effective.

Most commonly RCP/RCS/IFT for Revit and Navisworks, E57 for cross-platform use, FLS for FARO Scene, and PTS or PTX for legacy CAD. Other formats available on request.

We typically deliver LOD 200 for design-intent models, LOD 300 for coordinated tender-stage models, and LOD 350 to 400 where specific elements need to be fabrication-ready. We agree LOD per discipline at quote stage so you only pay for the detail you need.

Stated FARO accuracy is plus or minus 2mm at 25m. After registration of multiple scans, accuracy across an entire building is typically within 3mm. For most architectural and BIM uses this is well in excess of what is required. For specialist applications (precision dimensional control, machine setting out) we can quote against a tighter specification.

Yes. The scanner is silent and class 1 laser safe. We routinely scan occupied offices, retail spaces, residential properties and operational plant rooms with minimal disruption. We agree access and scan timings with the building manager up front.

A typical residential property is one day. A small commercial building is 1 to 2 days. A large or complex site is 3 to 5 days. We scan as many positions as the brief requires, with each setup taking 3 to 8 minutes.

Yes, almost always together. Where the project warrants it we combine ground-based scanning with drone-based aerial capture for roofs and upper elevations.

Yes. Most BIM tools accept E57 or RCP/RCS natively. We deliver in whichever format your team uses, set up to a sensible coordinate origin, and we are happy to walk your modeller through the file structure if helpful.
