The large slab on grade (S.O.G.1) may be constructed in 1 phase if desired as long as all contraction, construction and isolation joints can adequately be achieved. However, equipment pads (S1 & S2) and MRI slab (S.O.G.2 w/ haunches) should be poured as part of a separate phase.

Please see Philips’ Drawings.

31) On drawing sheet number AS600 equipment schedule item number F12 and F13 are noted to be furnished by VA and installed by Contractor. Please clarify that “Contractor” does not mean the general contractor and these items are installed by MRI machine supplier and is not part of our contract?

F12 has a typo. It should read, “Injector, MRI,” and is purchased by VA and installed by that vendor. F13 is a reference to the MRI equipment in its entirety, therefore the GC’s responsibilities are assigned in the Philip’s drawings.

32) On drawing 15-MH402 there is a piece of equipment AC-2SS/CU-1 ( split system air conditioner) for the MRI room. On drawing 15-M101 it indicates that the SACU unit is provided by Phillips.

The question I have is Phillips providing the Stulz unit AC-2SS which seems to part of the SACU?

This is a costly item so please clarify.

The SACU is provided by Phillips and installed by GC but is not a part of AC-2SS. Even though the dwg shows them together. The SACU is a duct control device that has nothing to do with AC-2SS. The Split system Stulz unit CU-1/AC-2SS is provided and installed by the contractor.
