3D laser scanning is a process of capturing the physical dimensions and shape of an object or environment using a laser beam. The scanner emits a laser beam, which reflects off the surface of the object and is captured by the scanner. This process is repeated many times, and the data collected is used to create a 3D model of the object or environment.
3D laser scanning has a number of applications, including surveying and mapping, architecture and construction, product design and engineering, and cultural heritage preservation. It is known for its high level of accuracy and speed, and it can be used to capture detailed, 3D models of objects and environments that would be difficult or impossible to measure using traditional methods.
The point cloud data can be viewed on a computer and used to create a variety of 2D and 3D drawings, such as floor plans, elevations, and sections. 3D laser scanners are known for their accuracy and speed, as they can survey hundreds of thousands of points per second and capture complex spaces quickly. They are also useful for surveying inaccessible areas, such as the underside of bridges or building facades.
Point Cloud Data: A dense collection of 3D data points that represent the scanned object’s surface.
3D Models: Highly detailed and accurate digital representations of the scanned object or environment, often in formats like .STL, .OBJ, or .FBX.
2D Drawings and Plans: Traditional floor plans, elevations, and sections derived from the 3D model, provided in formats such as .DWG or .PDF.
Mesh Models: Polygonal meshes that represent the surface geometry of the scanned object, useful for further processing or visualisation.
Topographic Maps: Detailed representations of the scanned terrain, showing contours and elevations.
Orthophotos and Images: High-resolution, geometrically corrected images that provide a detailed visual record of the scanned area.
BIM (Building Information Models): Comprehensive models that include detailed information about building components and systems, provided in formats like .IFC or Revit.
Inspection and Analysis Reports: Detailed reports that highlight measurements, deviations, and other critical analyses derived from the scan data.
Virtual Tours and Panoramas: Interactive 360-degree views that allow users to virtually explore the scanned environment.
In response to your enquiry, we need to discuss your specific requirements, including the areas to scan and the necessary outputs (e.g., BIM model, plans, elevations). After this discussion, we will provide a fixed price quotation for the work.
Our surveyors will visit your site to conduct a comprehensive 3D laser scan using the latest Faro technology. We will meticulously navigate the building to capture all the details discussed during the quotation stage.
Once the on-site work is completed, we return to the office to process and register the data. Our goal is to produce a fully registered point cloud file.
Once the point cloud file is complete, we can begin producing the elements you require, such as a BIM model, 2D drawings and plans, mesh models, and more.
3D laser scanners use lasers to create a 3D digital model of an object or environment. They work by emitting a laser beam and measuring the time it takes for the beam to bounce back after it hits an object. By measuring the time it takes for the beam to bounce back, the 3D laser scanner can determine the distance to the object and create a 3D model of it.
There are several different types of 3D laser scanners, including time-of-flight scanners, phase-shift scanners, and triangulation scanners. Time-of-flight scanners measure the time it takes for the laser beam to travel from the scanner to the object and back again. Phase-shift scanners measure the phase shift of the laser beam as it reflects off the object. Triangulation scanners use a laser and a camera to measure the angle and distance to the object.
3D laser scanners can be used for a variety of applications, including surveying, mapping, inspection, and reverse engineering. They are often used in manufacturing, construction, and other industries where accurate measurements and detailed 3D models are required.
The price of a 3D laser scan depends on the size and complexity of your property. Important factors that increase or decrease 3D laser survey costs include the survey area, the detail you require, and the quality of the companies undertaking the survey.
Typically, most surveying companies charge between £300 and £1000 for a day’s work on site. To follow on from the survey, time is required in the office to draw everything up. A day’s drawing in the office may be charged at £200 to £500 a day. Don’t forget to factor in VAT!
At THS Concepts, we prefer to give a one-off price for both the surveying and drawing work. That way, our clients know exactly what they are going to get and for how much.
3D laser scanning is a process that uses lasers to measure the physical properties of objects and environments in three dimensions. The data collected through laser scanning can be used to create 3D models and computer-aided design (CAD) drawings of the scanned objects or environments.
There are several steps involved in the process of converting 3D laser scan data into a CAD model:
Data collection: The first step is to collect the 3D laser scan data using a laser scanner. The scanner sends out laser beams and measures the distance between the scanner and the objects being scanned.
Data processing: Once the data has been collected, it must be processed to create a usable 3D model. This typically involves aligning and merging multiple scans, and cleaning up the data to remove any errors or inaccuracies.
CAD modeling: The processed 3D scan data can then be used to create a CAD model of the scanned objects or environment. This is typically done using specialized software that allows the user to manipulate the 3D data and create a detailed, accurate model.
Finalization: The final step is to finalize the CAD model, which may involve adding additional details or features, and ensuring that the model is accurate and ready for use in the desired application.
Overall, the process of converting 3D laser scan data into a CAD model requires a combination of specialized equipment, software, and expertise to ensure that the resulting model is accurate and useful.
Measured Building Surveys
Laser scanning a building is a quick way to capture precise and accurate detail for your project. The data captured can be transferred into a BIM program such as Revit for further design and analysis.

3D laser scanners and lidar (Light Detection and Ranging) systems are both technologies that use lasers to measure the distance between the sensor and objects in the environment. However, there are some key differences between the two technologies:
Purpose: 3D laser scanners are typically used to create detailed 3D models of objects and environments, while lidar systems are primarily used for autonomous navigation and mapping.
Scanning method: 3D laser scanners use a single laser beam to scan an object or environment, while lidar systems use multiple lasers that sweep across the field of view. This allows lidar systems to create a more detailed and accurate map of the environment.
Range: Lidar systems have a longer range than 3D laser scanners, which allows them to gather data from a greater distance.
Resolution: 3D laser scanners tend to have a higher resolution than lidar systems, which means that they can create more detailed and accurate models of objects and environments.
Overall, 3D laser scanners and lidar systems are both useful tools for measuring and mapping objects and environments, but they are used for different purposes and have different capabilities.
Topographical Land Survey
We can survey the land around your building, picking up key bits of information such as land heights, tree locations, outbuildings, changes in surface, drainage, and more.
See our topographical survey service
Utility Surveys
By default, we utilise 3D scanners on our measured survey projects to produce accurate 3D point cloud files. These are then translated into floor plans, elevations and sections etc.
See our utility scanning service.
We undertake surveys across the United Kingdom and internationally. Specific locations include:
Utilising our fleet of Faro 3D scanners and Leica total stations we accurately survey existing buildings and structures and produce 2D and 3D CAD data. We usually work with Architects on refurbishment projects looking to get accurate drawings such as floor plans, sections, and elevations.
We have scanned a number of high-profile buildings across the United Kingdom. These include:
Repairs and alterations
Using our calibrated Faro 3D scanners, we can produce feature-rich point clouds of the hull and internal areas of your vessel. Utilising point cloud data will assist in designing and manufacturing components to perfectly fit where they need to go.
We have been involved in several projects ranging in size and complexity. These include:
Using point cloud data of your vessel, we can accurately produce as-built drawings showing elevations, sections, and plans. We produce lines plans drawings taking sections through the hull at set intervals as well as verification of C Marks & Draught marks. We can check if these critical marks are accurate and set correctly in comparison to the underside of the keel/deck lines.
Historical/Heritage Vessels
3D laser scanning is a great method to capture historical vessels without the need to physically touch or measure the vessel. The colourised point cloud can be used to capture the boat and produce an electronic record for future alterations, repairs, and rebuilds.
Measurements for Yachts
We can accurately record the shape of a yacht’s hull (when dry-docked) to produce accurate plans, elevations, and sections. This can be useful for applications such as yacht racing where precise measurements are required for race verification.
3D laser scanning is an efficient and accurate method of capturing the physical dimensions and shape of existing infrastructure, such as roads, bridges, and buildings. By emitting a laser beam and capturing the reflections off the surface of the object, the scanner is able to create a detailed, 3D model of the object.
This process can be used to create accurate maps and models of existing infrastructure, which can be helpful in a variety of ways. For example, if a new construction project is planned in an area with existing infrastructure, the 3D model can be used to understand the layout and condition of the existing infrastructure and plan the new project accordingly. Similarly, if an existing piece of infrastructure, such as a bridge, needs to be repaired or maintained, the 3D model can be used to understand the exact dimensions and features of the structure and plan the work accordingly.
Overall, 3D laser scanning can be a valuable tool in the planning, design, and maintenance of infrastructure projects, as it allows for the creation of accurate, detailed models that can be used for a variety of purposes.
