Vanir used BIM for Million Air San Bernardino in order to run conflict detection and 4D simulation. Prior to construction, BIM was used to detect conflicts, such as mechanical and structural, between trades. This assisted the team in resolving many issues prior to actual construction, which saved the project from additional time and expense. In addition, the team used the model for 4D simulation by linking the project schedule into the model. This allowed them to resolve coordination issues as well as visually track any delays or potential delays that would affect the project’s completion date.
