<p>Clients pay for fast, defensible answers to three early-design questions: what changed, who has to act on it, and whether the fix actually got built.</p> <ul><li>What changed? Every publish from Revit or Navisworks is a versioned snapshot. Compare any two revisions element by element and you show the client the delta, not last month&#39;s PDF.</li><li>Who has to act? Issues are pinned to the elements they concern, with the sheet and revision attached. Each owner gets a 6am digest.</li><li>Is it really resolved? An issue closes only with a screenshot, a tagged user and the linked model commit.</li></ul> <p>That is the pitch. A clash caught in the model costs about $50, against $5,000 to $50,000 in the field, and owners know it.</p> <p>Plans are per license, from Basics at $260 a year to Max at $590, with unlimited projects and custom Enterprise pricing. If you want the work done for you, BidLight also delivers BIM execution plans, 4D sequencing and fabrication detailing.</p>
