  • Harris Sun thinks this is interesting:

Although it is nearly impossible to perfectly coordinate construction documents with or without BIM, a BIM specific process can help more clearly define project scope and budget issues to subcontractors and therefore potentially lessen any excessive contingencies during preconstruction (Figure 4.3). In addition, BIM promotes best services, not necessarily best cost. Although an estimate may be checked through peer review or by an estimating consultant, the goal is to have the best number as opposed to a lower number.
