# Research — field notes

What we look at before we sell or invest. Short field notes from the sites, campuses and contracts we work around. Written first, published once they are checked.

- **Note 02 · Forthcoming:** The sign-off chain: why contractor bills sit unpaid for ninety days.
- **Note 03 · Forthcoming:** What a school should ask before installing anything in its water line.
