<p>Treat the model as a starting point, coordinate what it shows and track the unknowns as issues. Existing conditions rarely match reality, so a messy model changes how you work, not whether you can.</p> <ul><li>Publish what you have. Even an incomplete model gives you a baseline snapshot to compare later revisions against.</li><li>Pin issues to the unknowns. Demo, hidden conditions and tie-ins are risks no model captures, so give each one an owner and a place on the record.</li><li>Update as the field reports back. Each publish is a new revision, compared to the last element by element.</li><li>Keep the evidence. Closing an issue takes a screenshot, a tagged user and the linked model commit.</li></ul> <p>The 6am digest keeps owners aware of what is still open, so unknowns do not sit quietly until they cost a crew a week.</p> <p>An unresolved clash can burn $15K to $50K a week in idle field labor. For documenting existing conditions, BidLight&#39;s BIM services team delivers as-built modelling.</p>
