Reality Capture & 3D Laser Scanning

Rockall Projects captures existing buildings, sites and vessels as millimetre-accurate 3D data, then turns that data into the drawings, BIM models and records your project needs. Leica RTC360 and BLK360, DJI Matrice 4, Leica Cyclone, Revit and Fusion. Hampshire, Dorset, London and nationwide.

What we deliver

  • Registered point clouds in E57, RCP/RCS and LAS, structured by level and zone
  • Measured building surveys: floor plans, sections and elevations in DWG and PDF
  • Scan-to-BIM models in Revit and IFC from LOD 200 to LOD 350
  • As-built and construction verification surveys against the design model
  • Drone photogrammetry: topographic surveys, roof surveys, orthomosaics and 3D site models
  • Marine and vessel scanning for refit, fit-out and fabrication
  • Digital twins and structured asset data for handover and operations

Equipment and software

Leica RTC360 (2 million points per second, 1.9 mm range accuracy at 10 m) for buildings and structures; Leica BLK360 for tight interiors and plant rooms; DJI Matrice 4 with RTK for roofs, sites and facades; Leica Cyclone REGISTER 360 for registration and QA; Autodesk Revit and Fusion for BIM and CAD modelling; Autodesk ReCap for client-ready point clouds.

Why clients choose Rockall for scanning

  • Run by a chartered construction project manager (MRICS, MCIOB), so every survey is scoped around what the design team and contractor will actually do with it.
  • Scope first: areas, accuracy, level of detail and formats are agreed before the scanner comes out, and assumptions are documented in the handover notes.
  • Fast turnaround on the South Coast: most single-building surveys are captured in a day and registered within 48 hours.
  • One firm from capture to model: no handoffs between a survey company and a BIM bureau.

Where we work

Our scanning team is based in Lymington on the Solent, so most of Hampshire and Dorset is within an hour. We regularly scan in Southampton, Portsmouth, Winchester, Bournemouth and Poole, the New Forest and across Dorset, and from our London office across the capital. For larger buildings and estates we work nationwide: our largest scan-to-BIM project to date covered 700,000 square feet at Canary Wharf.

Frequently asked questions

How accurate is 3D laser scanning?

A registered Leica RTC360 point cloud is typically accurate to within a few millimetres across a building. We agree the tolerance that matters for your use before surveying and state it in the handover notes.

How long does a scan take?

A typical 500 to 1,500 m² building is captured in one site day. Registration and QA follow within 48 hours. Drawings or BIM models take from a few days to a few weeks depending on the level of detail.

How is 3D laser scanning priced?

We quote per project. Price is driven by floor area, complexity, the level of detail you need (point cloud, 2D drawings or BIM) and access. Send us the address, the areas and what the data is for and we will quote within one working day.

Do you need scaffolding or a site closure?

No. Terrestrial scanning is non-contact and works around occupants. Roofs and high facades are captured by drone under our CAA GVC authorisation.

Can you work from a point cloud we already have?

Yes, subject to a check of coverage and quality for the areas and outputs required.

Do you only work in Hampshire and Dorset?

No. Hampshire, Dorset and the South Coast are our base, and we have an office in London, but we take on scanning and scan-to-BIM projects anywhere in the UK.
