Banner Desert 2A MOSU (Multi-Organization Service Unit), OR/Pre-Op Expansion and ED Resuscitation Bays project consisted of a complete remodel of Banner Desert Medical Center’s A Tower 2nd Floor, including three (3) new OR’s and enlargement of the existing Pre-Op.  The existing 1st, 3rd and 4th floors of A Tower each have (36) small (+/- 150 SF) inpatient rooms and this project is intended to provide (20) larger (+/- 280 SF) Banner template, AIA 2010 compliant, patient rooms.

Do to the complexity of the previous 36 room layout and the “new” 20 room layout, all plumbing water, waste, vent and roof drain stack riser piping had to be offset in the 1st floor ceiling to new 2nd floor wall locations and then reconnected in the 2nd floor ceiling to existing 3rd & 4th floors maintain normal facility operations during construction as these other floors would not be remodeled to the new room template until a future date. When this offset piping relocation occurred, future waste & vent pipe and fittings were added along with domestic water valves to minimize disruption to the floors above and below for future connection of the new piping from the 2nd floor.

Each floor of the original design is served by dedicated air handlers located in mechanical rooms on the particular floor served. As a part of this project scope, a new 55,000cfm Temtrol air handling unit was installed on the roof to serve two floors (2nd & 4th) with provisions of adding a future 55,000cfm air handling unit to serve the remaining two floors (1st & 3rd) at a later date when those floors are remodeled to match the new Banner room template. Two new shafts were constructed on the south side of the building to accommodate the new 84”x64” supply air and 108”x64 return air duct from the AHU down the building with dampers at all four floors.

New Temtrol air handling units were also installed for the Pre-Op / PACU (18,000cfm – within an existing penthouse) and CVOR (12,000cfm –2nd story roof) remodeled spaces.

As always, the fast track construction was aided by the fully coordinated BIM model driven and managed by W.D. Manor.
