What your team should be able to see.
- 01Every change to the documents you priced
Addenda, revisions and supplementary conditions, against the original.

The requirements the contract never assigns, raised before they fall to you.
- 03What would prove each requirement
So small items are closed as they happen, not argued at the end.
- 04Closeout requirements in one place
Submittals, warranties and record documents, cited to the clause.

- Tenant and fit-out changes
- Subcontractor scope gaps
- Architect direction
