<p>Because nothing keeps a record of what changed between exports. So your coordinators open files side by side, squint at PDFs, and try to remember what the duct looked like last week. That is roughly 11 hours a week lost working out which model version is current.</p> <p>The fix is versioning, not more meetings. BidLight runs inside Revit and Navisworks, and every export you publish gets versioned and compared element by element. You stop guessing which file is live. You see what actually moved.</p> <p>What that buys you on the job:</p> <ol><li>Publish straight from the model, so there is one live record instead of five copies on five laptops.</li><li>Every export is diffed element by element, so changes show up in about 15 minutes instead of a 90-minute meeting.</li><li>Issues get pinned to the element they concern, and close only with proof: a screenshot, a tagged user, the model commit that fixed it.</li><li>The 6am digest tells every owner what they own, and the project view shows who is behind while there is still schedule to recover.</li></ol> <p>Hours back. Fewer clashes reaching the field. That is the point.</p>
