Open BIM workflow eliminates proprietary lock-in and lets teams use their preferred BIM software without compatibility headaches. Clash detection happens in real time across disciplines, cutting rework costs by 20–30 percent in most projects. IFC-based coordination reduces manual coordination meetings and email chains by roughly half. Open standards lower switching costs and give firms genuine negotiating power with software vendors. Most firms claim to use open BIM but skip the governance step—that's where it breaks down.
