<p>Share the comparison because it is something you can defend and explain, not a note scribbled in an email.</p> <p>Here is what that looks like day to day:</p> <ul><li>Publish your model from Revit or Navisworks. BidLight keeps one live record of the project inside both.</li><li>Every publish is a versioned snapshot, and any two revisions compare element by element.</li><li>Send the comparison for the revisions that matter. If the client asks what moved between them, you can show them.</li><li>Point to the issue pinned to each affected element, with its sheet and revision.</li></ul> <p>That last part is the real win. No chasing scattered updates and no comparing PDFs side by side. When the scope shifts, the record shifts with it, and you already know why.</p> <p>A change caught in the model costs about $50. The same change found in the field costs $5,000 to $50,000. Owners want to hear that you saw it first.</p>
