Construction · Defined
Supplementary conditions
Project-specific provisions that add to or modify the general conditions of a construction contract.
Why it matters
Read them with the general conditions and agreement. A familiar standard form may be materially changed by supplementary provisions. Track the executed version, including amendments, rather than relying on a blank sample form.
In practice
A project example
A supplement changes the notice procedure for requests for additional time.
