3D Laser Scanning — Registered Point Clouds for As-Builts, Interiors, and Structures

What Terrestrial Scanning Captures That Aircraft Cannot

A drone sees the top of things. It maps a site, a roof, a corridor, a stockpile, and a canopy with a fidelity nothing on the ground can match. What it cannot see is the inside of a building, the underside of a bridge deck, the vertical face of a plant floor with pipe racks stacked three deep, or the mechanical room where the as-built drawings stopped being true fifteen years ago.

Terrestrial laser scanning fills that gap. A scanner on a tripod records millions of range measurements from each position, and a series of positions, registered together, becomes a single point cloud of the whole space — walls, columns, ducts, conduit, equipment, and structure, captured in the condition it is actually in rather than the condition the drawings say it should be. Where a project needs both, we tie the ground scans to the drone data so the site and the building share one coordinate system.

Two Scanners, Two Jobs

We carry two terrestrial systems because they answer different questions, and choosing between them is the first scoping decision.

Leica BLK360 — when the deliverable is a measurement

The BLK360 is a survey-class imaging laser scanner. It captures dense, accurate point clouds with matched imagery from each setup, and its output is what engineers, architects, and fabricators use when they need to model against existing conditions: as-built documentation for renovation and retrofit, MEP coordination in congested spaces, structural documentation, and dimensional verification. This is the scanner for anything that ends up in CAD or BIM.

Matterport Pro 3 — when the deliverable is the space itself

The Pro 3 is a LiDAR-based capture system built for speed and for a web-hosted result. It produces a navigable digital twin — a walkthrough anyone can open in a browser — with measurement tools, schematic floor plans, and an exportable point cloud. It is the right tool for facilities documentation, construction progress records, pre-bid site walks, and commercial property marketing, where the value is in everyone being able to see and measure the space without being in it. We cover it in more depth on the Matterport digital twins page.

The honest rule of thumb: if someone is going to build from it, it is a BLK360 job. If someone is going to walk through it, measure it, and share it, it is a Matterport job. Some projects are both.

How We Do It

• Scope and control. We agree the extent, the level of detail, and — if the cloud has to sit in a real-world coordinate system — the control strategy before anyone unpacks a case. Scans that only need to be internally consistent are registered to each other; scans that need to align with a site survey or a drone dataset are tied to surveyed targets.
• Scan positions. Setups are planned for overlap and line of sight, not for the fewest possible stops. Every occluded corner is a hole in the deliverable that someone will find later.
• Registration and QA. Scans are registered cloud-to-cloud and, where control exists, to it. The registration report — mean error, overlap, and any setups that had to be re-taken — ships with the data, the same way an accuracy report ships with every drone survey we fly.
• Inside and outside together. When a project needs the building and the site, the terrestrial cloud and the drone LiDAR or photogrammetry cloud are merged on shared control, so a designer works in one model rather than reconciling two.

Deliverables

• Registered point cloud in E57, RCP/RCS for Autodesk, LAS/LAZ, or PTS — with the registration report
• Matterport digital twin — hosted walkthrough link, measurement mode, and schematic floor plans, where the Pro 3 is used
• Panoramic imagery from each scan position, referenced to the cloud
• 2D extractions — plans, sections, and elevations cut from the cloud, on request
• BIM-ready deliverables through licensed engineering partners. When a project needs a modelled Revit or IFC as-built, we capture and register the cloud and a licensed engineering partner models from it under their responsible charge. You get one scan, one coordinated model, and a stamp where the project requires one.

Where Scanning Earns Its Cost

Renovation, retrofit, and adaptive reuse

Existing drawings are wrong in ways nobody discovers until demolition. A registered scan before design starts is the cheapest change order a project will ever avoid.

MEP coordination in congested spaces

Mechanical rooms, pipe racks, ceiling plenums, and process floors — anywhere a new run has to thread through existing services, the cloud shows exactly what is there.

Industrial and process facilities

Equipment replacement, tie-ins, and expansion planning in plants that cannot be shut down for a manual survey.

Condition and pre-construction documentation

A dated, measurable record of a structure before adjacent work begins, or of a facility at handover, that settles later disputes with data rather than recollection.

Facilities and real estate

Digital twins for space planning, tenant fit-out, insurance documentation, and marketing, shared by link rather than by site visit.

When We Will Tell You Not to Buy It

An open site with nothing vertical on it is a drone job at a fraction of the cost. A simple floor plan of an empty rectangular space does not need a laser scanner. And if what you actually need is a certified boundary or a sealed structural opinion, scanning is an input to that work, not a substitute for it — we will say so and bring in the licensed professional the project requires.
