What you get
Every unit rate shows the crew, the production and the hours behind it.
The estimate workbook has a tab for quantities, one for crews and equipment rates, one for the build-ups and a summary in bid-form order. Change a production rate or a fuel price in one cell and every affected unit rate updates.
Items priced on an assumption carry a flag and a note, so your bid review meeting starts with a list of the risks rather than a search for them.
