3D survey (BIM) for VSEs/SMEs: Use cases and feedback in 2024

The integration of 3D survey technologies and BIM (Building Information Modeling) offers innovative solutions for VSEs (Very Small Enterprises) and SMEs (Small and Medium Enterprises) in the construction sector. Originally reserved for large companies, 3D scanning is becoming more democratic, becoming an accessible practice for companies of all sizes. In 2024, VSEs and SMEs can now use advanced tools such as 3D scanning to improve their projects, whether it is renovation , 3D modeling , or building documentation. This trend is perfectly reflected in the evolution of 3D BIM surveying for VSEs and SMEs in 2024.

This article explores the use cases of 3D surveying for these companies, as well as feedback that shows how this technology contributes to their competitiveness in the construction sector.

1. 3D Survey: What is it and why do VSEs/SMEs need it?

3D surveying involves capturing the exact dimensions of a building or infrastructure using 3D scanners (laser or photogrammetric). This data is then used to generate detailed digital models , often integrated into BIM systems.

The interest for VSEs/SMEs lies in the ability of 3D scanning to offer a precise and rapid representation of the real conditions of a site. This is crucial for renovation, construction, or maintenance projects.

1.1. Using 3D laser scanning to capture buildings

3D laser scanners enable fast and accurate 3D laser surveying of buildings, reducing human errors often associated with manual measurements. The point clouds generated by these scans are then converted into BIM models that facilitate decision-making for contractors.

1.2. 3D structural modeling and mapping of buildings

3D structural modeling provides a better understanding of the load-bearing elements of a building, which are essential for the renovation or modification of existing structures. The 3D maps resulting from the survey provide detailed representations of buildings, from their geometry to the MEP (mechanical, electrical, plumbing) networks.

2. Use Case of 3D Survey for VSEs/SMEs

2.1. Building renovation with 3D scanning

One of the most common uses of 3D scanning in small businesses is building renovations . Thanks to 3D scanning , it is possible to create a detailed BIM model of the existing building. This model includes all the exact dimensions, including the smallest structural details, thus facilitating the planning of renovations and reducing the risk of errors.

Practical example

An SME specializing in the renovation of historic buildings used a 3D laser survey to capture all the architectural details of a heritage-listed building. Thanks to the generated 3D model , they were able to design a renovation plan without damaging the historic elements, while optimizing the use of modern materials.
