<p>They quit because the work is a grind, not estimating. Your best estimator spent the day chasing who changed what, hunting issues across Teams, email and Bluebeam, and comparing PDFs side by side to see what moved between exports. That is not the job they signed up for.</p> <p>When nobody keeps a record of the model, they become the record. They field the same question twice. They rebuild the same takeoff. They sit in a coordination meeting for two hours figuring out who moved a duct and why.</p> <p>Meanwhile a clash sits unresolved and the work behind it stops. That is $15K to $50K in field labour standing idle every week. Whoever is closest to those numbers feels that pressure personally.</p> <p>BidLight runs inside Revit and Navisworks and keeps one live record of the project. Every export is versioned and diffed element by element, so changes show up without anyone hunting. Issues arrive by 6am, sorted by who owns them.</p> <p>Takeoffs stop getting re-run. Costs pull from current pricing and update when the design changes.</p> <p>Your estimator gets to estimate again. Instead of being the project&#39;s memory.</p>
