Typical Applications of 3D Laser Scanning Technology in the Construction World

More than ever before, new technology is transforming the way things are done in the construction industry. One kind of technology that has had a big impact on the construction world is 3D laser scanning technology. With this kind of technology, construction contractors can digitally capture the dimensions of a whole building construction project using a laser beam. The scanner produces a point cloud image, which is an accurate and a detailed 3D representation of the scanned building. Common applications of 3D laser scanning technology include construction of new buildings and renovation of existing ones. These two applications are further discussed below.

Construction of New Buildings

3D laser scanning can be used in several aspects of a new building construction job to facilitate the building information modelling (BIM) process. For instance, scanning each part of the building during installation can provide a time-lapse record with millimetre-accuracy data on the structural steel used to reinforce concrete slabs, as well as the actual time of installation. This information can be compared with the initial building design to ascertain that all components are installed as required. If any incompatibilities are learned, the design may be reviewed so that construction parts can be modified in the fabrication process rather than making costly alterations at the construction site later on.

In addition, 3D laser scanning is instrumental when it comes to quickly evaluating the slab levelness of concrete surfaces by helping to measure the extent to which certain areas need to be adjusted and the exact quantity of material needed. This results in more accurate material orders and reduced waste at the construction location.

Modification of Existing Buildings

As for building renovations or extensions to an existing structure, drawings are normally outdated or just don't exist. This complicates the process of drawing up updated designs for renovations or extensions. A 3D laser scanner can locate and capture the structure in real-time and in its exact form. This data can be relied upon to develop highly accurate drawings for the current renovation. When these representations have been created, laser scanning can keep adding value by digitally capturing key construction landmarks and providing quality assurance for project, from start to finish.

While 3D laser scanning technology is still beyond the financial reach of many small construction companies, it is a powerful tool that can save lots of money in rework. What is more, it provides construction contractors with vital information, while ensuring that projects are completed in record time. Even if the cost of installing laser scanners is too high, you can outsource the scanning job to a service provider.
