8. 1/AE 401 – What are the requirements of the Cryogenic Quench Exclusion Zone (currently not existing on roof of other MRI)?

Spur Design – The MRI Design Guide states that “the exclusion zone should be clearly marked, and staff and contractor should be restricted from working in the area until they have been educated to the risks of cryogenic gasses escaping the vent pipe.” The Cryogenic Quench Exclusion Zone is to be coordinated with the MRI Manufacturer.

In addition to Spur Design comments: The area within the RF zone of the MRI #1 roof and MRI equipment room as shown on DWG. FP101 Fire Protection Plan for MRI #1 shall be included in the phasing plan. Zone within that existing RF boundary and above the operating room will not be accessed unless coordinated and MRI #1 is not in operation.

KFC Engineering - Elevations shown in documents is the assumed elevation based on the as-build drawings. Actual elevations will need to be verified in the field during construction.

11. 1/S500 Please reference detail below….is the indicated area already notched, or will this area need to be part of the demo?

KFC Engineering - The exact thickness is unknown. Allow for up to a 4” thick slab for demolition.

15. Is the existing MRI #1 going to remain operational? If so, how or when will work in Room 120 be completed?
