An added advantage : Building Information Modeling (BIM)

Like many English speaking regions and Scandinavia and Asia, BIM & BIMinfra is a growing trend in construction sector in France thanks to a number of nationwide initiatives.

By associating with this growth, AMBER GREEN has the ambition to leverage techniques from the BIM sector (digital design, collaborative project management, contractual supply chain articulation), thus accelerating the integration of renewable energy into the fabric of our society.
