However, if the Government is unable to permit access, the Government at its own risk and expense shall maintain these facilities and the Contractor shall not be responsible for the service involving any of these facilities during the period of nonaccess, unless the service failure results from the Contractor's fault or negligence.
(b) During periods when the Government does not permit Contractor access, the Government will reimburse the Contractor at mutually acceptable rates for the loss of or damage to the equipment due to the fault or negligence of the Government.
