ASI in Construction: What an Architect's Supplemental Instruction Is and How It Works
An ASI clarifies or lightly adjusts contract documents during construction without changing contract sum or schedule—when it does affect cost or time, teams pivot to the change order process.

What ASI can and cannot do
ASIs can clarify details, lock finishes, resolve ambiguities, or provide revised graphics when work remains within the contracted scope and price/time stay neutral. They cannot add material new scope, override code, or silently move dollars or dates—that requires owner-approved change documentation.
Common issuance triggers
- Ambiguous wall transitions or missing connection graphics after RFIs
- Minor owner selections that do not impact contract sum/time
- Field discoveries needing drawing adjustments without compensation events
Workflow and documentation
Track ASI numbers, references, acknowledgement, and field distribution—high volume often signals upstream CD quality issues. Pre-submission QA on architectural and spec vs drawing alignment reduces avoidable ASIs.
How InspectMind helps before CA
Catch coordination conflicts and ambiguous details while CDs are still editable—shrinking the ASI/RFI churn that hits architects and engineers during construction administration.
Frequently asked questions
Does an ASI change price?

RFI asks; ASI instructs with formal record.
