<p>A change proposal survives value engineering when every point traces back to the model and a clear owner. Claims from memory or an old markup fall apart the moment someone pushes back.</p> <ul><li><strong>Changes come from the model.</strong> Compare the proposed revision against the current one. BidLight shows what moved element by element, by category.</li><li><strong>Conflicts have a pin.</strong> Issues attach to the element and carry the sheet and revision they came from, so you can answer where a problem was raised.</li><li><strong>Owners are named.</strong> Each open issue sits against a person, and the 6am digest tells them what they own.</li><li><strong>The record moves with the design.</strong> If VE swaps a material or resizes a room, publish and compare instead of waiting for the next meeting.</li><li><strong>You can show your work.</strong> Open the comparison on screen and walk through it.</li></ul> <p>A proposal defended by trust me does not survive VE. One backed by a model comparison does, and it takes about 15 minutes instead of a 90-minute meeting.</p>
