<p>The hidden cost is the change nobody saw. It surfaces on site as rework, and by then a fix that costs about $50 in the model costs $5,000 to $50,000 in the field.</p> <p>BidLight catches the change at the source:</p> <ul><li>Install BidLight in Revit and publish from the model.</li><li>Each publish is a versioned snapshot with its own files, author and milestone.</li><li>Compare any two revisions element by element, grouped by structural, MEP, envelope and interior.</li><li>Pin issues to the affected elements and close them with proof.</li></ul> <p>Plans are priced per license, billed annually or monthly: Basics at $260 a year ($30/month), Core at $330 ($39/month), Complete at $440 ($51/month) and Max at $590 ($69/month). Every plan includes unlimited projects, and AIA members get discounts of up to 29%.</p> <p>If your team is slammed, BidLight can also take on the BIM work: execution plans, 4D sequencing and fabrication detailing.</p>
