<p>Yes. When a trade builds or fabricates from an old export, the work no longer matches the design, and you pay to redo it. The fix cost grows with every day it goes unnoticed.</p> <p>A clash caught in the model costs about $50. The same clash found in the field costs $5,000 to $50,000.</p> <p>BidLight keeps everyone on the current model:</p> <ul><li>Every export is a versioned snapshot with its author and milestone, so there is one answer to which version is current.</li><li>Compare the current revision to the one the trade is working from. Differences show element by element, by category.</li><li>Pin an issue to any element that changed after the trade started, and tag the owner.</li><li>Let the 6am digest put it in front of them.</li></ul> <p>Many teams lose about 11 hours a week to version confusion, and that is before counting the work built to the wrong file.</p> <p>Check what changed before the crew builds, not after.</p>
