Check the bids
Put block by wall type next to your mason's number, and tonnage next to the fabricator's. A bid far under the others usually means missing scope, and a traced takeoff shows you where. See how to check a mason's block count.
Run the floor
Show the crew the build-up of each wall type, measure off the model, and see which materials are needed on the floors you're working now. See the buying order.
Price it per building
No seats to count and no AI add-on. One price per building, quoted from your set. Compare: Setout and the alternatives.
