You’ll get fewer OAs, later in the process. For occupancies starting in the second half of FY24 and after, your first OA arrives just before we award the lease or construction contract, based on actual bids.
Approve OAs promptly. Every OA now represents a contract action waiting on you. The award OA documents what your agency owes us once the contract is awarded, so delays in approval delay your project.
Your Client Project Agreement still comes first. A CPA captures your space parameters and initial cost estimates. It is not a financial commitment — that begins when you approve the OA.

Traveler reimbursement is based on the location of the work activities and not the accommodations, unless lodging is not available at the work activity, then the agency may authorize the rate where lodging is obtained.
Unless otherwise specified, the per diem locality is defined as "all locations within, or entirely surrounded by, the corporate limits of the key city, including independent entities located within those boundaries."
Per diem localities with county definitions shall include"all locations within, or entirely surrounded by, the corporate limits of the key city as well as the boundaries of the listed counties, including independent entities located within the boundaries of the key city and the listed counties (unless otherwise listed separately)."
When a military installation or Government - related facility(whether or not specifically named) is located partially within more than one city or county boundary, the applicable per diem rate for the entire installation or facility is the higher of the rates which apply to the cities and / or counties, even though part(s) of such activities may be located outside the defined per diem locality.
