The continuous growth of the laser scanning technology would give a boost to the construction sector, facilitating the owners, buyers, stakeholders, and all other construction professionals. 

Do your construction projects make use of the technology, or are you still investigating its possibilities? When it comes to 3D building scanning, one thing is for certain: any construction expert would profit from understanding more about the technology. Take a closer look at the developing technology right here.

📝 What Is Laser Scanning in Construction?

3D Laser scanning services, also known as high-definition surveying or reality capture, is a technique that uses laser rays to collect incredibly fine and accurate data of a construction site. A laser beam measures various dimensions of the structure such as the length, width, and height of the building components, as well as their connection to one another. The process of scanning uses a specific technology for scanning the objects on a construction project. The technology is known as LiDAR (Light Detection and Ranging). 

Laser scanning has made its mark not only in the Architecture, Engineering, and Construction (AEC) industry, but also in various other sectors such as films & media, gaming & technology, medical, manufacturing, automobiles, and many more. 

Even though the laser scanning technology has taken a little longer to reach the construction field, it is gradually becoming a standard on construction sites all over the world. 

The laser scanner creates a point cloud image that accurately replicates the scanned items. Scanners can be used up to a distance of several meters away, depending on the make & model of the 3D scanner. Building Information Modeling (BIM) and Computer Aided Drawing (CAD) systems can then be used to create either 2D CAD drawings or 3D Revit BIM models from the data acquired. 

The models and drawings created using the point cloud data assist the professionals of the Architecture, Engineering, and Construction (AEC) industry to carry out the construction process effectively, accurately, and in a more precise manner. 

📝 The Basics : Laser Scanning

It’s worth taking a moment to define the technology precisely before we get into the details. In particular, laser scanning, commonly referred to as high-definition surveying (HDS) or reality capture, is a technique for accurately mapping an area using a laser.

Laser scanning is used to collect precise information for every nook and corner of a site on a construction site. The term “point cloud” refers to the data it offers building industry specialists. a network of points connected in a 3D coordinate system. We could go into great depth regarding point clouds and what they can do, but the most crucial thing to keep in mind is that they maintain an incredibly accurate digital record of an area or an object as it relates to a project.

📝 How does 3D Scanning Work in Construction?

Laser Scanning is a technique that uses laser light for scanning the surrounding objects. But the question is how do 3D laser scanners work? What is the procedure? Let’s learn about the step-wise procedure of Laser Scanning. 

  • Place the equipment at a certain point that is to be scanned. 
  • Calibrate the camera with respect to the surface. 
  • Start the scanning process. 
  • Collection of data in the form of the point cloud. 
  • Transfer the raw data to the software. 
  • Create a 3D BIM model / as built BIM model using the point cloud data. 

📝 Benefits of Laser Scanning in Construction

Construction teams can take planning and detail to a whole new level using laser scanning. This enables scans to be performed and accessed immediately, which improves productivity and reduces rework. 

  • Cost Effectiveness: The laser scanning process requires a lesser duration than the conventional surveying process, eliminating the expense incurred by the utilization of resources for a longer duration.
  • Saves Time: Quicker than traditional surveying, laser scanning can perform building scans within minutes. 
  • Accuracy and Precision: The modern day laser scanning technology is way more accurate & precise as compared to traditional surveying. It is because 3D laser scanning eliminates human errors. 
  • Detailed Documentation: The point cloud data obtained during the laser scanning process is so detailed that it captures practically every feature of the object being scanned. The likelihood of any omission during the scan is much minimized, and the likelihood of any error is relatively low. 
  • Reduces Manual Labor: Utilization of unwanted resources and labor is eliminated by 3D laser scanners, which results in cost and time efficacy. 
  • On-site Safety: Construction sites are concerned about the safety of workers and other employees. Portable 3D laser scanners for surveying can take precise measurements from up to several hundred meters away. It helps the workers to keep away from hazardous surroundings and topography, ensuring their safety.

📝 Drawbacks of Laser Scanning in Construction

  • High Initial Cost: The initial cost of the laser scanning camera is very high. 3D scanners can cost anywhere ranging from $20,000 to $150,000. 
  • Lack of Knowledge of the Technology: The laser scanning technology is still not known in some areas and the people there lack the knowledge of 3D scanners and laser scanning. 
  • Lack of Trained Professionals in the Industry: Due to the lack of trained professionals, there is a lack of adoption of laser scanning technology. The professionals in the construction industry must be trained through certified laser scanning courses. It benefits the professionals personally and the Architectural, Engineering, and Construction (AEC) industry as well. 

📝 What Does the Future Hold for Laser Scanning in Construction Industry?

The use of static 3D laser scanners and the expertise of skilled surveyors and scanning experts will always be a top priority requirement for construction projects in order to attain precise and high accuracy survey data. Nonetheless, the demand for quick 2D drawings and 3D models that are independent of the environment is driving the use of mobile scanning technology. 

It will be necessary in the future for new hardware scanning devices to integrate with the digital world of BIM and cloud-based processing. A larger range of workflows, including scanners and other reality capture equipment, must be incorporated in order to improve the value of scan data to all parties involved in the process. 

Construction professionals and surveyors must be aware of new technologies and cloud-based advancements since they will have a significant impact on cultural and operational changes in the field.
