<p>A large share of a coordinator&#39;s week goes to chasing changes instead of resolving clashes. About 11 hours a week go to working out which model version is current.</p> <p>BidLight keeps one live record of the project inside Revit and Navisworks. You publish the model and each publish is a versioned snapshot with its own files, author and milestone. Any two revisions compare element by element, so there is no side-by-side PDF comparison and no long meeting hunting for who moved what.</p> <p>Two things give the time back. The comparison shows what changed in about 15 minutes instead of a 90-minute meeting. And issues are pinned to the elements they concern, so each owner sees what they own in a 6am digest without being chased.</p> <p>Plans run from Basics at $260 per license per year to Max at $590, with unlimited projects and custom Enterprise pricing.</p> <p>You stop chasing scattered updates, and your coordinator goes back to resolving clashes while they are cheap: about $50 in the model, against $5,000 to $50,000 in the field.</p>
