If a GSA customer agency, or GSA, forces the relocation of another GSA customer agency prior to the expiration of the customer's OA, the “forcing” agency is responsible:
(a)
For all reasonable costs associated with the relocation of the agency being “forced” to move, including architectural-engineering design, move coordination and physical relocation, telecommunications and ADP equipment relocation and installation;
(b)
To GSA for all of the relocated agency's unpaid tenant improvements, if any; and
(c)
To the customer agency for the undepreciated amount of any lump sum payment that was already made by the agency for alterations.
