Occupancy Agreement Space Inventory System (OASIS)

With a tenatitve launch date of July 2023, Public Buildings Service will transition from our current occupancy Agreement tool (OATool/eOA) to a new OA application - the Occupancy Agreement and Space Inventory System (OASIS).

The information and resources on this page will assist PBS customers in preparing for a seamless transition to the new system.

Immediate Changes to GSA Processes for Occupancy Agreements

OASIS will provide a more efficient and effective way for customers to manage their OAs, but there will be changes associated with the transition. Starting immediately, for occupancies effective in the second half of FY24, GSA will send the first OA right before lease or construction contract award, based upon actual bids. This timing change will greatly reduce the volume of OAs sent to customers. The award OA will document a customer’s financial obligation to GSA once a contract is awarded. All OAs will, therefore, represent a pending contract action waiting for customer approval and OA approval is needed in a timely manner to avoid delaying your project.

As part of the project planning process, GSA will continue to provide Client Project Agreements (CPAs) around 30 months prior to a customer;s occupancy\ effective date (for non-prospectus projects). For prospectus projects, CPAs will be provided around 12-18 months before OMB submission, at the end of strategic requirements development. The CPA is not a financial commitment. It records the high level parameters for your space and the project's initial financial estimates, The financial obligation comes later upon approval the OA sent shortly before contract award. Learn more about the CPA here; the financial information is captured in Part 2, section h.
