<p>You build a defensible record by tying every item to an element and a revision. Arguments are won when the evidence holds up in the room.</p> <p>Here is how BidLight gets you there:</p> <ul><li><strong>Start from your Revit model.</strong> Publish straight from the model, or the federated model in Navisworks.</li><li><strong>Keep every version.</strong> Each publish is a snapshot with its own files, author and milestone, so nobody argues about which one is current.</li><li><strong>Compare revisions.</strong> Differences appear element by element, grouped by category, so you show exactly what moved.</li><li><strong>Pin the issue.</strong> It carries the sheet and revision that raised it.</li><li><strong>Close with proof.</strong> A screenshot, a tagged user and the linked model commit.</li><li><strong>Show ownership.</strong> The 6am digest and per-person resolution rates (the Problem Solver Index) make it visible who owns what.</li></ul> <p>When a trade pushes back, you open the record instead of rebuilding the story from email. That is how disputes shrink.</p>
