PROJECT NUMBER: 589A4
-
13
-
120, RELOCATE CANTEEN AND KITCHENPROJECT NUMBER: 589A4
-

-
102,
RELOCATE CARDIOLOGY

The Cardiology spec does not say what is the current direct digital control
system, please clarify

The Canteen and Kitchen spec says the current direct digital control system is Siemens, please verify

Answer:

The facility has migrated to the Tridium AX DDC control system. That is the system that needs to be used
on the DDC system
for all three projects. A revised spec section 23 09 23 is attached that is applicable to
all three projects.



Question:

I need some clarification on what is intended for the computer room split system units.


The ACCU’s and
part of the refrigerant pipin
g are shown as Phase 1 items and the CRAC’s and other part of the
refrigerant piping are shown as Phase 2 items.


Should the ACCU’s and CRAC’s both be furnished in
Phase 1 and only the ACCU’s installed or are we actually supposed to purchase the ACCU’s and

associated CRAC’s in separate phases?

Answer:

The computer room split units are included
in bid item 2. If bid item 2A is awarded then there are no
computer room units needed. The reason why the plans show the ACCU’s on phase 1 and the CRAC’s in
phase 2 i
s because the refrigerant piping would be routed through the phase 1 ceiling space which
would prevent having to get access to the phase one ceiling space after it is completed.
