<p>It holds up because every proposed change can be checked against the model. VE meetings cut ideas that feel soft, and the quickest way to test one is to see what it touches.</p> <ul><li>Publish the option as a revision. It is a versioned snapshot, not a sketch on a screen.</li><li>Compare it to the current baseline, element by element, by category: structural, MEP, envelope, interior.</li><li>Read which trades the option reaches, and pin an issue to each element that another trade has to absorb.</li><li>Tag owners, so the follow-up is assigned before the meeting ends.</li></ul> <p>Nobody has to guess whether swapping an assembly pushes work onto another trade. The comparison shows it.</p> <p>A change pushed through without that check tends to come back later as rework. A clash caught in the model costs about $50. Found in the field, it costs $5,000 to $50,000.</p> <p>You still make the call on the trade-off. BidLight makes sure the call is made with the model open.</p>
