3D Laser Scan

Laser Scanning is a non-contact, non-destructive device that draws pictures of any physical objects on the computer screen. The material things are obvious and show all the edges on the computer screen. This technology is used in architecture and engineering as well. The first 3D laser scanner was invented in 1960. It was time-limited. People used this technology later, and scientists continually made changes. Now, we use the developed form of this technology.

3 Dimensional  Laser Scanning in Architecture

In architecture,  laser scanning is used to design projects, visit the sites, monitor them, and track the quality of the project. With the help of a 3D scanner, architects create effective and organized models, and it also helps them track project success.

Application of 3D Laser Scan

The application of laser scanning in the construction field is given below.

Use for Site mapping

The engineer use laser scanning services for the site mapping. 3D scanning accurately maps all the edges and angles of the construction.

Assurance of quality

The quality of the construction is essential. Engineers and builders always try to check the quality in every stage of construction. 3D scanners make this work easy. Engineers use this technology to ensure quality.

Draw the building

3D scanner draws the image of the building. So the construction team can easily track the process and see how the building looks at every point.

3D Laser Scanning

Track the record

This kind of laser scanning helps the project manager track the construction records. So, the project manager updates the construction status with the help of the following documents.

3D models

With the help of laser scanning, architects draw the model of a building or any other project. The 3D model shows all the corners and points of construction.

The procedure of Laser Scanning in Construction

The procedure consists of different stages. However, the details of these steps are given below.

Plan of scanning

In the first step, plan what you are going to scan. In this procedure, three key factors are considered. They include the scope of the scan, the area location, and the details of the scanning level. We also see the details of the equipment used during scanning. The third key factor of this laser scanning is handling the potential hazards according to the project needs.


In the next step, scan the data and upload the information. The scanning process depends on the information that is uploaded. In the first step, set the laser scanner toward the object. The scanner emits light and creates a graph of the things. Scan the needed area and repeat this process multiple times. The scanning process is repeated until you get accurate information.

Processing of 3D scanning

3D scanning involves cleaning up the data, registering the data, and creating a surface representation of the object. Before using this technology, it is advisable to clean the data. Because sometimes errors occur and providing results may not be accurate. If you want to register a 3D scanner multiple times. The image of every object is written according to the requirement.

Use of 3D laser scanner

The 3D laser scanning is used for multiple purposes. For example, we use it to measure objects, check the progress of projects, draw graphs, detection of errors, and make safety assessments.

Advantages of 3D Laser Scanner

The 3D scanner plays a vital role in the field of construction. Without a scanner, no structure is possible. There are a lot of benefits of 3D laser scanners that are given below.

1. Save the time

3D scanners capture much data, store information, analyze data, and give suggestions. So this becomes the reason for time-saving. Now, Architecture can save their time. They analyzed the projects in a short time.

2. Accuracy in measurement

3D laser Scanner captures the image of the object with all details and all corners of the thing. It shows a clear picture. So, the architects and engineers easily understand the measurement of material. It increases the accuracy of measurement procedures.

3. Authentic information

The measurement of the 3D scanner is correct and to the point. So the reconstruction team gets ethical information. Moreover, provide the complete details of the documentation. The document is clear and easily understandable, which helps the all team to follow.

4. Help in collaboration

Architecture makes graphs with the help of engineer collaboration. Using a 3D laser scanner, they quickly create a clear picture of projects. The easy picture of the projects helps the other construction team understand it and follow their duties.

5. Safety of workers

In traditional construction, people use tape and meters to measure the walls and other materials. In this procedure, the risk to the worker’s life increases. 3D scanners reduce this risk and secure the worker’s life.

6. Handle the budget

In the human measurement, the error chance increases. Wrong sizes become the reason for the uncontrolled budget. Using a 3D scanner allows you to control the project’s budget.

7. Decrease the human work

In the past, construction needed a lot of labor to complete work on time. In the past believed that more labor meant fast work. But now, this concept has changed. 3D laser scanners reduce the human creation. Currently, only need a little human labor in construction.

8. Multiple scanning

The best part of this laser scanning 3D modeling is that it can scan multiple times. The updated version of the 3D scanner creates numerous images of objects with one contact lens. Now only need to change Lenz for some things.

9. increase the quality of work

3D scanners improve the quality of work. The chance of error is reduced. It makes a clear picture of the project’s presentation.

10. Organized management works

With the help of a 3D scanner, the management team became organized, and the quality of work increased. The 3D shows the complete details of the projects that are easily understandable for the entire construction team. This creates the clarity. The owner of the contract easily tracks the team’s progress.

Limitation of Scanning

With a lot of advantages, there are some limitations of this technology. Some limitations are given below.

Need investment

The equipment used in the 3D laser Scanner needs a lot of investment. Their equipment is expensive and not easily available in the market.

Used in large-scale

The use of this technology is based on the large scale of the projects. People prefer something other than this technology in the residential based because their rates and machinery are very costly.

Issue of accuracy

The result of accuracy depends on the calibration and the system’s scanner. Only expert people know about this technology and their correct use.


The system of this technology is very complex and technical. So, the consultant hires those who know about this technology and use it. Skills required to manage the scanning in construction.
