BIM in Infrastructure projects is now widely deployed. openBIM is defined by two the approaches : one leads to the provision of information to describe the digital asset; the other follows the standardized processes of contracts. Altogether, it makes the traceability essential for confidence. Thus the work to develop openBIM has reached a high level of maturity with tangible results. This work is the fruit of the players in the Infra sector, creating an ecosystem ready to rapidly deploy openBIM in all projects over the entire life cycle of a project.
