**Who this is for:** the people who price work and buy it: estimates, APUs, quotes and subcontracts.

Quantities you can trace to the model, unit prices built from your own data, bids leveled line by line and embodied carbon screened from the same quantities.

## Leave these running
- Submittals due: https://aibuilderacademy.netlify.app/routines/submittals-due-lookahead.md

## A typical week with an agent
- Takeoff from the latest model with the "not measured" list.
- Bid tab with clarifications sent the same day.
- Carbon hotspots for the design team when materials are chosen.

## Never let the agent
- Invent a price, a productivity or an emission factor.
- Present a plug as a bidder's price.
- Recommend an award on price alone.
