<p>The honest answer is you&#39;re losing the hours you can&#39;t bill. Every time an export lands, someone has to diff it by hand, chase what moved, and re-check sheets against the model. That&#39;s where the senior estimator&#39;s week disappears.</p> <p>BidLight keeps one live record of the project inside Revit and Navisworks. Exports are versioned and diffed element by element, so you see exactly what changed and who owns it. No side by side PDF comparison. No guessing.</p> <p>What that gives your estimator back:</p> <ol><li>No manual export comparison</li><li>No rebuilding the same sheet checks</li><li>No chasing updates across Teams, email and Bluebeam</li><li>Costs update when the design changes, in minutes</li><li>The numbers stay defensible for bids</li></ol> <p>There is also a daily digest of what you own, delivered by 6am, so the coordination meeting is not spent discovering who moved what.</p> <p>We publish 18,000 hours saved across teams. Your number will vary, but the shape is consistent: the estimator stops reconciling and starts estimating.</p>
