<p>Because the cost is spread across other people&#39;s budgets. The electrician waits, the foreman reschedules, the GC extends a rental, and nobody adds it up under the clash that caused it.</p> <p>Here are the numbers. A clash caught in the model costs about $50. Found in the field, it costs $5,000 to $50,000. Left unresolved, it can burn $15K to $50K a week in idle field labor. One that sat 47 days cost $28,000.</p> <p>The problem is usually visibility, not effort. The issue sits in an email thread or a markup that the owner never saw.</p> <p>BidLight pins each issue to the element it concerns. It carries the sheet and the revision it came from, and it shows against its owner. The 6am digest lists what each person owns, and the project view shows who is behind while there is still schedule to move work.</p> <p>You cannot track a cost nobody owns. Give the clash an owner on day one and you stop paying for it by the week.</p>
