<p>Yes, if you compare revisions. Your Revit model holds every element, and BidLight compares published revisions so you can see which changes land on top of other trades.</p> <p>BidLight runs inside Revit and Navisworks. There is no manual redraw and no re-keying of changes into a spreadsheet.</p> <p>Here is how it works in practice:</p> <ul><li>Start from your model as it is. Publish it as a snapshot.</li><li>After the next design change, publish again and compare. Differences appear element by element, by category.</li><li>Look at where structural, MEP, envelope and interior changes meet. That is where rework starts.</li><li>Pin an issue, assign an owner and close it with proof.</li></ul> <p>The reason to do it in the model is the gap. A clash caught in the model costs about $50. The same one found in the field costs $5,000 to $50,000.</p> <p>BidLight does not run automated clash detection. It tracks model changes and clashes or issues between revisions, pinned to the elements.</p>
