<p>Yes, probably. Steel changes ripple into ducts, pipes and supports within weeks, and an old markup cannot keep up. By the time someone notices, the crew has installed it.</p> <p>Most workflows freeze the model the moment a package goes out. Nobody compares the new revision unless someone remembers to. The gap between the issued set and the current model is where rework starts.</p> <p>With BidLight, every publish is a versioned snapshot. Compare the current one to the revision the field has and you see the changed steel elements, grouped by category. A clash found in the model costs about $50. Found on site it costs $5,000 to $50,000.</p> <ul><li>Compare revisions every time a structural package changes.</li><li>Check structural and MEP categories first. They collide most often.</li><li>Treat every design change as a cue to confirm the field has the right revision.</li><li>Make revision confirmation a checklist item before every pour or install.</li></ul> <p>The goal is a record you can show when a GC or trade pushes back.</p>
