<p>A live record takes the gamble out because it moves with the Revit model, so you never coordinate against a stale drawing.</p> <p>BidLight keeps one record of the project. When the design changes, you publish again and the impact shows up right away, before it turns into rework.</p> <p>Where the confidence comes from:</p> <ul><li>Every publish is a versioned snapshot, so you compare revisions and see which elements changed.</li><li>Issues pin to elements and carry the sheet and revision they came from.</li><li>A closed issue has a screenshot, a tagged user and the model commit behind it.</li><li>The 6am digest shows who is behind while there is time to recover.</li></ul> <p>Each decision traces back to an element and a revision, which is what lets you defend it when a trade pushes back. A clash caught in the model costs about $50. In the field, $5,000 to $50,000.</p>
