(a) The standard levels of service covered by GSA Rent are comparable to those furnished in commercial practice. They are based on the effort required to service the customer agency's space for a 5-day week (Monday to Friday), one-shift regular work schedule. GSA will provide adequate building startup services, before the beginning of the customer's regular one-shift work schedule, and shutdown services after the end of this schedule.

(b) Without additional charge, GSA customers may use their assigned space and supporting automatic elevator systems, lights and small office and business machines including personal computers on an incidental basis, unless specified otherwise in the OA.
