1) Sheet 54-GI-101 & 54-GI-102

a) Key Note 2 on sheet 54-GI-102 states that the ICRA barrier wall is Type “A” plastic sheet barrier (see Type “A” on Sheet 54-GI-101). Type “A” is detailed on Sheet 54-GI-101 but does not indicate the location of the NPV monitor needed per ICRA Class III requirements. Please

Verify that the digital manometer is required per Class III specification.

i) NPV monitor is not required due to the building not being occupied by patients or public. Verify with COR this is still correct.

Containment Measures Box” states that the Barrier Type is: Plastic Walls. However, the note below states that “boundary shared with public or patient care areas must have hard walls.”

Please clarify on the Basement Infection Control Plan (Sheet 54-GI-101, Detail drawing #1) which construction barriers will need to be “hard walls” as they are all noted to be Type “A”, Note #2, Plastic Sheet Barriers.

a) Because the building is not being occupied by patients or the public at this time, plastic sheet barriers are to be used for dust control. Verify with the COR that occupancy status has not changed.
