Excelize has a team of highly skilled and seasoned experts who capture and translate 3D scan data for our customers.
By combining point cloud technology with our BIM experience, we are able to maximise the value of point cloud technology. A point cloud is a set of data points in a 3D coordinate system that reflect a building’s exterior surface. The 3D scanned data captures every last detail, obviating the need for additional site visits.
Let’s start with the aspect you’re probably already familiar with: BIM (Building Information Modeling). Building Information Modeling (BIM) is a highly interactive approach that helps various partners to work together on the planning, design, and development of a building using a single 3D model.
Getting exact measurements to work with is essential for creating realistic models. The accuracy of dimensions and 3D model material in BIM-projects has reached new heights thanks to 3D laser scans. Scan to BIM creates a workflow that is data-rich, linked, and constructible.
So, what exactly is Scan to BIM?
A laser scanner is used to take a detailed 3D scan of the real-world conditions on a project during the Scan to BIM phase. After that, the scan data is imported into a 3D modelling environment to generate realistic as-built models or to inform the template of real-world conditions.
From the point cloud, experts build BIM templates.
A variety of industries, including supermarkets, general contractors, and architects, are now using point cloud scan to BIM. MEP programmers, MEP consultants, and consulting engineers all use it. The ability to explore the variations between point cloud and model geometry by constructing native Revit geometry from and to a point cloud is scan to BIM’s key advantage.
Data can be exported or imported in a format that is understandable by electronic surveying devices, allowing you to read survey data for as-built conditions and export concept data for field verification using the scan to BIM model.
Let’s have a look at the most popular use of scan to BIM facilities.
- For retrofit, refurbishment, and restoration programmes, Scan to BIM assists in the development of as-built BIM Models.
- It allows for the construction of as-built BIM models for infrastructure assets such as tunnels and bridges that are being renovated.
- It is used to build as-built BIM templates for MEP services, which assist managers in detecting clashes early.
- It facilitates the development of intelligent BIM models in Revit by supplying clients with precise point cloud data.
- It aids in the measurement of points within the scan in order to easily determine true measurements.

Contractors use 3D laser scanning for a variety of reasons.
Contractors can easily collect as-is conditions on a building site using 3D laser scanning, resulting in precise and up-to-date data that is useful during the design and development processes. It is then used to validate as-built models, monitor project development, build as-built models for existing systems, or supplement design data that is lacking. Many buildings now need a builder to deliver a point cloud as a final project deliverable to the building owner in order to chart the site of new construction.
Scan to BIM enables you to quickly construct a highly detailed three-dimensional visual model of the structure.
Some of the benefits of scanning to BIM include:
- It eliminates a significant amount of human error from standard as-built documentation workflows.
- The information is gathered in a much shorter amount of time.
- Information can be exchanged more quickly.
- To gather data, teams only need to access the site once.
What is Scan to BIM and how does it work?
Scanning is the process of gathering information.
Contractors can capture field data quickly and accurately thanks to advanced 3D scanning technologies. The 3D laser scanner is mounted on a tripod and features a high-speed spinning eye-safe laser. The direction of the laser beam relative to the scanner is registered as an X,Y,Z coordinate (also known as a “point”) as it reaches a solid surface. A point cloud is a collection of millions of these points that together form a highly accurate digital image. Following the collection of points, the scanner can take colour data, which will be used to colourize the scan in order to produce an accurate 3D representation.
So, what steps do you take to convert your scanned data into a BIM model? Check out this video of a 3D laser scan at a historic structure, or read the steps below.
From scan to BIM in 7 easy steps
1. Make sure you have a target in mind before sending someone out to gather data for your Scan to BIM initiative. What will be done with the information? You would be more effective in the capture of scan data on a project if the team knows what you’re going to do about it.
2. Delegate scanning to anyone who can go to the project site.
3. The person doing the scan must first set up the scanner and enter certain parameters, such as the scan density and the number of measurement points to be taken for each scan.
4. A scanner can only record what it sees (line of sight). You’ll need to take several scans from various places to get a full picture of the build. You would be the most effective of your time if you understand the function of your scan results.
5. Use a USB drive or a cloud file-sharing network like Trimble Connect to transfer data from the scanner to a server.
6. Individual scans must be registered into a single composite point cloud before being shared with others. To log, analyse, and model your results, use point cloud modelling software. Learn how to make a 3D model from a point cloud by reading this blog.
7. After the point cloud has been registered, you can import the data into your modelling applications and begin generating constructible model material using the point cloud data and your construction skills.
Information flows (almost) smoothly from field to office when 3D laser scanning is used in a BIM operation, enabling contractors to produce constructible models in no time. Scan to BIM is undeniably changing the way builders work now, placing data and linked information at the centre of the building process.
