What document is used for minor changes in work without altering the contract time or sum?

The document used for minor changes in work without altering the contract time or sum is called Supplemental Instructions. These instructions allow the architect or designer to provide additional information or correct minor discrepancies that can be addressed without significant modifications to the contract. This mechanism ensures that the project can continue smoothly without the need for formal change orders, which typically involve more significant adjustments in scope, schedule, or cost.

Supplemental Instructions are particularly useful for small adjustments that might arise during construction, such as clarifications in details, adjustments in materials, or other non-disruptive changes. The use of this document keeps the process efficient and minimizes delays or disruptions to the work, as it eliminates the need for extensive negotiation over formal changes when the adjustments are minor.

In contrast, the other options represent different processes or documents related to changes in the construction contract. Change Orders typically involve larger modifications and adjust contract sums or time. Construction Change Directives allow for changes to be made without the contractor's consent but still involve more substantial changes than what is typically addressed with Supplemental Instructions. The Final Application for Payment is related to the financial aspect of the contract, not directly linked to minor changes in work.
