SPACE BENEATH THE ACCESS FLOOR WILL BE USED AS AN AIR DELIVERY

PLENUM AND CONTRACTORS ARE TO TAKE PRECAUTIONS WHEN

INSTALLING THEIR WORK SO AS NOT TO IMPACT THE INTEGRITY OF THE

PLENUM SPACE SPECIFIC TO AIR LEAKAGE AND CLEANLINESS.

ANY PENETRATIONS OR HOLES IN THE UNDERFLOOR PLENUM ARE

REQUIRED TO BE PROPERLY SEALED TO PREVENT AIR LEAKAGE.
