Augmented reality will improve construction conformity

26 June, 2019

In partnership with other construction industry stakeholders, VINCI Construction has set up a new company called DISCERN to roll out the widespread use of augmented reality on construction sites.

An R&D project led by Dodin Campenon Bernard recently highlighted the importance of augmented reality on construction sites. Its ability to make the invisible visible makes it an extension of the digital model by enabling superimposition of a digital drawing onto the actual construction at a given point in time to make it easier to understand and check where particular facilities are to be installed or integrated.

To achieve this, VINCI Construction has joined forces with Chantiers de l'Atlantique, Clarte and Arnaud Cosson to set up DISCERN in February this year. Based in Laval, the new company markets augmented reality software that facilitates assembly compliance checking, for example. The operator uses a tablet or smart glasses to view the retrieved digital drawing of the installation under construction, and superimpose it on the real-life situation to check that service ducts and routes are consistent with the drawing and have been correctly assembled.

“This new tool is designed to eliminate the familiar digital divide between the design office and the construction site”, summarises DISCERN Chairman Arnaud Cosson. “In building construction, corrective coring, for example, can impose enormous additional costs”. This operation involves boring new holes in concrete walls to allow services to pass through following a ducting location error.

Initially used to improve installation conformity, augmented reality software can also be used to improve the traceability of operations, assembly, maintenance or operation of connected installations.

Time saving and optimum efficiency: augmented reality at Roland-Garros

Augmented reality is already in action on some projects. The construction design work for the project to upgrade the Philippe-Chatrier tennis court at the Roland-Garros Stadium was carried out using a BIM system. The service networks (heating, water, etc.) were installed using smart glasses to superimpose the actual situation onto the digital model. Used in this instance by VINCI Construction France subsidiary PETIT, augmented reality made it possible to converge the virtual and real worlds; a technique that was applied as part of checking underground service networks.
