MasterFormat gives each section a six-digit number and a title. Most sections have three parts: General, Products and Execution.
Part 1 covers submittals, warranty and quality rules. Part 2 names the products and manufacturers. Part 3 tells you how to install and test.
Read all three parts for your section. Mark every related section it names. Compare the products in Part 2 with what the drawings show.
Takeoff Tool finds your spec section inside the Project Manual. It lists what the section requires and finds those items on the plan sheets.
