What AI does well
- It reads a full Project Manual and finds your section.
- It lists what the section requires.
- It finds those items on the sheets and counts them.
- It compares the spec with the drawings and finds where they disagree.
What AI should not do alone
- Guess a number when a sheet is unclear.
- Decide whether an item is in your scope when the documents conflict.
- Apply your company's own rules without being taught them.
Can ChatGPT do a takeoff?
A general chat assistant can read one PDF and answer questions about it. It does not hold a full plan set, track which sheet a count came from, or remember your company's rules. A takeoff you send out needs each number tied to its source.
How Takeoff Tool handles it
Every line is graded Certain, Maybe or Not sure. Each line links to its source. A person approves every line that is not certain before the takeoff is final.
