<p>You get rework after the job gets moving, or you lose weeks holding work back out of caution. Steel changes ripple into every trade that touches it, and a 30-day-old revision can be well off on a large structural package.</p> <p>The hidden costs stack up:</p> <ul><li><strong>Rework.</strong> The crew installs to the old geometry and tears it out later.</li><li><strong>Idle crews.</strong> Work waits while people work out which version is current. That is $15K to $50K a week behind an unresolved clash.</li><li><strong>Repeated meetings.</strong> Someone re-checks the changes by hand instead of fixing them.</li><li><strong>Weaker credibility.</strong> Trades stop trusting the drawings they receive.</li></ul> <p>BidLight keeps one live record inside Revit and Navisworks. Each publish is a versioned snapshot and any two revisions compare element by element, so the steel changes show up by category. Pin issues to the changed elements, assign owners and close them with a screenshot, a tagged user and the model commit. You stop working from a revision you hope is still current.</p>
