Construction · Defined
Architect’s supplemental instructions (ASI)
Written architectural clarifications or instructions for minor changes that do not adjust the contract sum or contract time under the applicable contract procedure.
Why it matters
If an instruction has a cost or schedule effect, identify that effect and follow the contractual change process. The ASI label does not settle a disputed entitlement.
In practice
A project example
A finish location is clarified without added cost; a proposed equipment substitution with a price increase requires separate change documentation.
