Anyone who sends out subcontract packages knows this. The invitation comes from the template, the scope split from the last job, and nobody has opened the prime contract since it was signed. What the package doesn't show stays with you.
One case on our Try page: an electrical and low-voltage package. Yesper drafted the invitation to bid with the prime contract flowed down, and a 96-line scope matrix. 20 lines gave the sub no quantity to price. The Wing A milestone and its liquidated damages weren't in the template.
The gaps show up on your desk, not in the change order log, and the bids come back on the same scope. Same for the rest of the Try page: tenders compared against the scope split, a bid package checked before it goes out, quantities from an IFC model.
