<p>Everything in BidLight comes from your own model and your own team. Nothing is pulled from an outside cost source.</p> <p>You publish from Revit, or from the federated model in Navisworks. Each publish becomes a versioned snapshot with its own files, author and milestone. That snapshot is the record.</p> <p>Here is what sits in it:</p> <ul><li><strong>Geometry and metadata</strong> read from the model, grouped by category: structural, MEP, envelope, interior.</li><li><strong>Issues</strong> pinned to the elements they concern, carrying the sheet and revision they came from.</li><li><strong>Proof of resolution</strong>: a screenshot, a tagged user and the model commit that fixed the issue.</li><li><strong>Ownership</strong>: who holds each issue, and who is behind, shown in the 6am daily digest.</li></ul> <p>The point is one record kept as the work happens. Nobody rebuilds the history from email threads. The cost control follows from that: a clash caught in the model costs about $50, and the same clash found in the field costs $5,000 to $50,000.</p>
