Preventative Maintenance Schedule-Maverick & EASL

1.0 MAVERICK & EASL CLEAN ROOMs:

1.0.1 The workload requiring a clean room/ ISO complaint space has been suspended and the room repurposed for another workload. Although the clean room certification requirement no longer exists, TYAD desires to retain reversionary capability.

1.0.2 The modular clean room structures in Building 1B bay 2 Maverick, and the 1A EASL as well as associated gowning/airlock/vestibule rooms are NOT currently used as certified clean rooms. Therefore annual room certification for ISO compliance is not required nor is routine maintenance on the associated ancillary/ anti-room vestibule air lock and similar preventative maintenance measures on the room itself.

1.0.3 However, TYAD MAY BE REQUIRED TO PLACE THESE ROOMS BACK INTO SERVICE and reserves the ability to perform emergency repairs and/or preventative maintenance and certification within the scope of this contract. ONLY TO BE PERFORMED UPON REQUEST BY COR AND UNDER UNSCHEDULED/ EMERGENCY SERVICES

1.0.4 If requested the HVAC unit preventative maintenance shall be performed at TYAD per the preventative maintenance requirements below. Each area served by a dedicated HVAC system serving the space.
