<p>When the model changes but the field is not told, the crew builds to the old geometry and the difference comes back as rework. That gap is where money leaks.</p> <p>Most coordination workflows freeze the moment a package is issued. The architect swaps a wall assembly, the engineer resizes ductwork or the client asks for one more revision, and the field&#39;s set is wrong. Nobody re-checks every time.</p> <p>BidLight closes the gap because it runs inside Revit and Navisworks and versions every publish. Compare the latest snapshot to the one the field has and the changes list element by element.</p> <ul><li>Pin an issue to each changed element.</li><li>Assign an owner so it shows in their 6am digest.</li><li>Close it only with a screenshot, a tagged user and the linked model commit.</li></ul> <p>A clash found in the field costs $5,000 to $50,000 and can burn $15K to $50K a week in idle labour. The same one caught in the model costs about $50.</p>
