<p>Because every time you answer from memory, you are doing the same investigation for free and risking a wrong answer. Someone asks what changed, and you dig through email, Teams and old exports to find out.</p> <p>With BidLight, the answer is already on record:</p> <ul><li>Publish your model from Revit or Navisworks. Each publish is a versioned snapshot with its own files, author and milestone.</li><li>Compare any two revisions element by element, grouped by category.</li><li>Send the comparison instead of explaining it.</li></ul> <p>You save the hours, and you stop being the project&#39;s memory. When someone asks about a layout change, you point to the revision that delivered it.</p> <p>A wrong answer from memory turns into rework. A clash caught in the model costs about $50. The same clash in the field costs $5,000 to $50,000. If coordination work is a service you sell, the record is what makes it worth the invoice.</p>
