Q-U57. When using annual AIG Allocated grants to reimburse a large multi-year project, will each grant require its own specific usable unit of work?

No.  For phased projects, the grant offer must include a special condition that requires the sponsor to complete a safe, useful, and usable unit of work within a reasonable timeframe.  Each grant agreement must specifically describe the work being reimbursed under that grant.  Refer to Section 3-21 of the AIP Handbook.
