Project Award Change (PAC) forms are distributed by DRDA to identify any changes in terms and conditions, additional funding, time extensions, and other modifications after an award notice goes out.
The PAC form indicates the reason for the modification, with reference to the sponsor notification regarding the change, and notes any additional reporting requirements, changes to project duration (e.g., as a result of a "no cost time extension"), and funding changes.
(Not to be confused with the project award change REQUEST form for projects under the Federal Demonstration Partnership. See /policies/federal/fdp.html for more information on such projects and requests.)
