1. Contractor’s personnel and all subcontractor’s personnel that will be operating a vehicle or equipment on the airfield (inside flight line fence) are required to attend flight line driver training. The only exception to this will be haulers (truck driver), who will be escorted on and off the airfield by someone with proper flight line certification. Vehicular traffic inside the flight line fencing should be kept to a minimum.

2. At the start and completion of each work day the contractor’s superintendent will check in and out with Airfield Management.

This is to occur in person at Bldg 169.

3. Drawing sheet M101, Detail 2: Delete the requirement to install the emergency HVAC shutoff switch (E-stop) located just inside the Mechanical Room door. The switch will instead be installed at the end of the main corridor where shown on sketch below.
