<p>Tie every design change to a record the field can see. The back-and-forth happens when the model changes and the people building do not know yet: someone moves a wall, and the answer you gave the foreman three days ago is already wrong.</p> <ul><li>Work inside Revit, not around it. BidLight runs in Revit and Navisworks, so there is no side channel that goes stale.</li><li>Publish each change as a versioned snapshot with its author and milestone.</li><li>Compare it to the revision the field is working from, element by element.</li><li>Pin issues to the affected elements and tag the owners.</li><li>Let the 6am digest carry the change to them.</li></ul> <p>When the field asks what changed, you point to the comparison. When the design asks who has been told, you point to the issue and its owner.</p> <p>The comparison takes about 15 minutes instead of a 90-minute meeting. Fewer calls, and rework that stays in the model, where a clash costs about $50.</p>
