A trucking company needed a construction bid to hand to their lender, while our own internal estimate was still mid-review with the project architect and the Strata subcontractor hadn't even been engaged on that portion yet.
I had the architect mark up the internal working estimate first, in a private review pass, before any version went out. Then planned a separate, owner-facing bid specifically for the client to submit to his lender.
A lender needs a finished bid, not a live working estimate still carrying internal review flags and caveats. Send the internal version straight to a bank and you risk a document that reads as unfinished getting treated as final by a party who has no context for what's still being checked.
The architect and I scheduled a same-day markup pass on the internal estimate before we produced the version meant for the client's lender submission.
A bank version and a working version are not the same document. Don't let one leak into the other.
That's about protecting a client from having to see, or be held to, an internal process he has no part in and doesn't need visibility into.
