What should the A/E issue to make a change in the contract documents that does not involve time or money?

In the context of construction documents, the correct choice in scenarios requiring modifications that do not affect time or cost is the Architect's Supplemental Instruction (ASI). An ASI is typically used by the architect to clarify or interpret the contract documents without altering the contract's terms significantly.

This instrument is particularly advantageous for making minor adjustments, interpretations, or clarifications that do not necessitate a formal change order or addendum. The changes made via an ASI are generally straightforward enough that they can be handled without the need for renegotiation or additional compensation.

In contrast, other options like a Change Order and a Construction Change Directive involve modifications that typically may impact contract price or schedule, thus making them less appropriate for changes that are strictly about clarification. An addendum generally pertains to changes made during the bidding process rather than after a contract has already been awarded. Therefore, when the aim is to modify designs or other details without incurring time delays or additional costs, the ASI serves as the appropriate and effective solution.
