Recommended 1400 x 600pxWhat is a 3D Laser Scanning Survey?
A 3D laser scanning survey uses specialist equipment to capture millions of accurate spatial measurements in a very short time, creating a detailed digital representation known as a point cloud. This data provides a precise record of existing conditions, capturing complex geometry that is difficult or time-consuming to measure using traditional methods.
Point cloud surveys are particularly valuable on complex buildings, refurbishment projects and sites where access is limited — capturing everything in a single visit and reducing the risk of having to return to site for missed information.

Our Scanning Process
Fast, Accurate Data Collection
Laser scanning is used to efficiently capture complex geometry using the Leica BLK360. Dense, accurate point cloud data is collected with minimal site disruption. Where required, scans are tied to OS grid coordinates and levels to ensure compatibility with wider site and design information.
Data Processing & Quality Assurance
Point cloud data is processed and registered using Autodesk ReCap, aligning individual scan positions into a single, coherent dataset. The registered point cloud is checked for accuracy, alignment and completeness before delivery.
Fast, Reliable Delivery
Final point cloud data is issued in agreed formats and timescales, ready for direct use in CAD, BIM and professional design workflows. We can also extract 2D CAD drawings from the data as part of a combined scan-to-plan service.

What is 3D Laser Scanning?
3D laser scanning is a survey technique that uses a specialist instrument to capture millions of precise spatial measurements in a very short time. The scanner emits laser pulses in all directions, measuring the distance to every surface it can see. The result is a dense cloud of three-dimensional points — known as a point cloud — that together form an accurate digital representation of the scanned space.
Each point in the cloud has an exact X, Y and Z coordinate. The complete point cloud gives you a precise, measurable record of the building or space as it exists — one that can be navigated in 3D, measured at any point, and used as the basis for CAD drawings, BIM models and detailed analysis.
We use the Leica BLK360 — one of the most capable compact laser scanners available for building survey applications. Its combination of accuracy, speed and non-intrusive operation makes it ideal for all types of building, from occupied offices to heritage structures.

How the Leica BLK360 Works
The Leica BLK360 is an industry-leading compact laser scanner that captures complete spherical point clouds with integrated HDR photography. Here's what happens from site visit to delivered data.
Scan capture
The BLK360 is positioned at multiple locations around the building. At each position, it performs a full 360° spherical scan — capturing up to 360,000 points per second across the full surrounding space. Each scan takes just a few minutes.
HDR photography
Simultaneously with the scan, the BLK360 captures high-dynamic-range photography from the same position. This is used to colourise the point cloud, giving each point the colour of the surface it represents — making the dataset far more intuitive to navigate and interpret.
Registration
Individual scan positions are aligned and merged into a single, coherent point cloud using Autodesk ReCap Pro. This registration process uses common points between overlapping scans to achieve a seamless, accurate combined dataset.
Accuracy and control
Where required, scans are tied to OS National Grid coordinates using control targets — ensuring the point cloud occupies the correct position in space and can be aligned with site surveys, drawings and other consultant data.
Quality checking
The registered point cloud is reviewed for accuracy, completeness and alignment before delivery. Areas of poor coverage or alignment are identified and addressed — either by additional scanning or by flagging to the client.
Delivery formats
The final point cloud is delivered in RCP/RCS format (for Autodesk software) and E57 (open format compatible with most CAD and BIM platforms). 2D CAD drawings can also be extracted from the data as part of a combined scan-to-plan service.
The Advantages Over Traditional Survey Methods
Millimetre-level accuracy
The Leica BLK360 captures data to millimetre accuracy — significantly more precise than hand measurement, particularly on complex or irregular geometry.
Complete spatial capture
Laser scanning captures everything visible from each scan position. No feature is missed because it was not individually measured — the entire space is recorded in a single pass.
Fewer site visits
A single scan session captures all the data needed for plans, elevations, sections and a BIM model. Returning to site to re-measure missed elements is virtually eliminated.
Minimal disruption
The BLK360 is compact, quiet and non-intrusive. It can operate in occupied buildings with minimal impact on normal activity — no drilling, no marking, no mess.
Permanent digital record
The point cloud is a permanent, measurable record of the building at the time of survey. It can be interrogated and re-measured at any time — long after the survey visit.
Foundation for BIM
Point cloud data is the most reliable basis for producing accurate as-built BIM models. Modelling from scan data rather than hand measurement produces significantly more accurate Revit models.
What Goes Wrong Without Proper Scan Data
Laser scanning is particularly valuable on complex projects where traditional measurement falls short. Here are the situations where the absence of scan data causes the most problems.
Hand-measuring complex geometry
Curved walls, vaulted ceilings, irregular rooflines and complex structural elements are extremely difficult to measure accurately by hand. Errors are common and compound across the building.
Missed dimensions causing design clashes
Traditional surveys capture only what is individually measured. Structural elements, services routes and awkward junctions are frequently not recorded — and discovered when new design elements clash with them on site.
Modelling from inaccurate base data
BIM models produced from hand-measured drawings contain the errors of those drawings. Inaccurate models mislead coordination decisions and create problems during construction.
Repeated site visits for additional information
Without a comprehensive scan, design teams frequently identify missing information during design development — requiring additional site visits that add cost and delay.
Heritage buildings without a digital record
Historic and listed buildings benefit enormously from a permanent, millimetre-accurate digital record. Without one, any future works must start from scratch with measurement.
What Affects the Cost
Laser scanning costs depend on the size, complexity and intended use of the data. We provide transparent quotes covering survey, processing and delivery.
Building size and number of scan positions
More scan positions are needed for larger buildings or spaces with many obstructions. Each additional position adds time on site and in processing.
Deliverable type
Point cloud data alone costs less than a combined scan-and-draw service. Adding 2D CAD drawings or a Revit BIM model to the scope increases the overall cost but significantly increases the value delivered.
Required accuracy and control
Surveys tied to OS grid coordinates require additional control target work. Higher accuracy requirements may call for more scan positions and closer overlap.
Building complexity and access
Buildings with complex geometry, multiple levels, restricted access or occupancy constraints take longer to scan efficiently and may require additional planning.
Processing and registration
Large or complex scan datasets take longer to process, register and quality check. This is factored into our quotes.
Turnaround time
Standard delivery is within 5–10 working days of the site visit. Faster turnaround can be accommodated — please mention any deadline when enquiring.
