Augmented Reality (AR): BIM on the construction site

Numerous initiatives regarding Augmented Reality (AR) on the construction site can be found online. Perhaps the most famous one is the D4AR from M Golparvar-Fard. VTT is also very active on AR in the construction industry. Most projects using AR technology on a building site, focus on the technology of markers and image recognition. However, the Netherlands Organisation for Applied Scientific Research TNO, in 2008 (!!) created a prototype using very accurate, markerless localization of the user. This creates new possibilities to enable different kind of uses cases on which we will not elaborate in this blogpost (read the paper to get details about this). The reason why this post is on our blog is because there is a link between the AR prototype and the BIMserver software.

Since a few months the AR prototype (which uses a localizer with an accuracy of 0,2mm in 3D) is able to receive streaming data from a remote BIMserver. A link is created between the receiving AR unit on the construction site, and a sending BIMserver in a datacenter. The means that changes from the engineering team can be evaluated live and in real time on the construction site. This gives the  contractor the security that he always gets the latest version of the data.

There are also future plans to create a two-directional link between the AR unit and a BIMserver. This will give the contractor (or any other user on a construction site) the ability to propose alternative solutions, but also feed the administration (procurement system) and use Systems Engineering on site.

The project team developing the AR unit is looking for investors to create a market ready product of the AR technology. For more information, contact rogier.donkervoort@tno.nl.
