Top Benefits of Using 3D Laser Scanners for Your Project

3D Laser Scanners are highly useful surveying tools for project planning and management. In this article we are taking a look at what 3D laser scanners are and the top benefits they could have on your project.

What is a 3D Laser Scanner?

3D laser scanners are a useful surveying instrument that emit a laser beam from a rotating mirror towards the area that is being scanned, with the laser beam being reflected back to the scanner when objects are in its path. The distance and angles between objects are captured and then stored in point cloud data, which can then be used to draw up floor plans, cross sections, elevation and built drawings for projects. 3D laser scanning is a crucial component for Building Information Modelling (BIM) and 3D modelling.

Top Benefits of 3D Laser Scanners

Accuracy and Detail

One of the top benefits of using laser scanners for surveying is that the level of detail captured, and the accuracy of this data, is highly comprehensive and the chance of any omission is hugely reduced, with minimal risk of error. As a result of the high level of detail provided from laser scanning surveys, the need to revisit a site for missed or inaccurate measurements is eliminated.

In addition, the data from laser scanners can be presented in a 3D model, allowing for surveyors, clients, and project managers to visit the site virtually, rather than having to actually travel to the site every time.


3D laser scanners capture and record millions of data points within a matter of seconds, which allows for large environments to be surveyed within a short timescale, with little downtime required. As a result, 3D laser scanning is an ideal surveying option for projects that are time-sensitive. This innate speed and flexibility not only makes 3D laser scanning suitable for a wide range of projects, but it is also one of the main reasons why 3D laser scanning is becoming a more widely used service within the industry.

Non-contact data capture

Another benefit of 3D laser scanning surveys is that they are a non-contact and non-invasive surveying method, making them a suitable option for projects involving sensitive objects and environments. 3D laser scanners can be used to produce data for heritage sites, as they involve minimal to no physical interaction, ensuring there is no damage or disruption caused.

Reduce Risk and Costs

3d laser scanners are a great tool to help you plan and manage your project effectively, minimising the likelihood of costly and potentially dangerous mistakes being made during construction and building works.

In addition, the remote nature of documentation from the 3D scanner, which allow surveyors to capture environments without having to physically access the area, ensures the safety of surveyors whilst also reducing the requirement for costly health and safety measures having to be put in place for the survey to take place.
