MEP System

 

Central Plant (lower Level):

The new boiler plant will serve the existing hospital and for future expansion. A new chiller plant will serve this addition and be set up for future expansion. The Central Plant will leave room for even more possible future expansions. The control system will be an automated system. All systems described will be designed with the intent of reaching the LEED “Silver” Certification.


Steam systems:


The Steam System will have five (5) 350hp boilers including piping and accessories.  It will include all valves for future additions to the steam system at this time. There will be space left for two additional 350 hp boilers, including valves for the future addition to the steam system at this time.
The system will have a new flue stack routed up along the existing North building. System shall include steam header, feed water, surge tank, chemical treatment, blow down separator, water softeners, flue gas economizer, ventilation, temperature controls, ect. All systems shall be sized for the addition of a future boiler.
There will be new piping through the new addition and connected to the existing mains located in the ceiling space of the lower level of the existing building.
Heating water will be supplied by two steam-to-water heat exchangers; one standby. The heating/reheat system will be served by two variable speed, based mounted, pumps; one pump will run while the other remains standby. Each floor will have an independent, direct return piping arrangement.  


Chilled water/Condenser water:

Build a new chiller plant to serve this addition and future additions.  Provide a new two cell cooling tower on the new ground floor roof.  Provide sound attenuating louvered screen wall.  
New cooling tower pumps & chilled water pump package shall include headers, valves, drives, controls, and provisions for future additions to the system. The pump packages are located in the lower level chiller room.
Provide (2) 750 ton centrifugal chillers/pumps to the chiller plant.   (Adequate space will be left in the Plant for an additional 750 ton chiller and an additional cell to the cooling tower on the roof to serve the future. Size piping for future additional chilled water load.)


Ventilation:

Provide a new dedicated ventilation system in Chiller and Boiler rooms.  The Chiller Room will be built to meet ASHRAE Guideline 15. The Boiler Room shall include combustion air fans and a general exhaust system. System will provide intake and relief louvers associated with the chiller, boiler ventilation systems and the central storage HVAC unit.  There will be ventilation and exhaust ductwork and sound attenuating louvers to serve new generators. They will route the generator exhaust up along the new East stair tower.


Building Automation System (BAS):

The existing Control System will be upgraded and include a new web based system. Upgrade will include replacement of existing controllers, cabling, new Application and Data Server, graphics, and owner training. The new boiler system, chiller/tower system, generator/ fuel system, HVAC units, exhaust fans, unit heaters, cabinet unit heaters, and all other new mechanical and electrical systems shall be connected to the BAS system. A new temperature control air compressor shall be provided, sized to serve new and existing systems.


Plumbing:

The Plumbing system will rework the existing hospital storm and sanitary sewer systems that currently discharge to the city sewers located on 24th Street. It will route new gravity sewers to the north and connect to new sanitary and storm stubs.
A new storm sump located in the lower level will serve an underfloor drain tile system and footing drains. A new sanitary ejector will serve the lower level floor drains and misc. plumbing fixtures. The new additions ground, first, and future floors storm and sanitary sewers will flow by gravity to the west side of the site.
A new domestic water, fire, and gas service will enter the new addition on the west side. The backflow preventers and meters shall conform to local requirements. The new system will extend and connect the new water and gas service to the existing main within the existing hospital. Also, it will extend a new water service to the MOB building.
The steam to water domestic hot water heaters will be added to the Central Plant to serve the new addition and back feed to serve the existing hospital.  These (3) units are sized to serve the future additions and will be connected to the existing piping system.


Medical gases:

All medical gases and vacuum units will be upgraded to allow for increased capacity. This will include a new medical vacuum, anesthesia evacuation and medical air pumps that will be added to the existing system. Nitrous oxide & nitrogen tank systems will be further evaluated.  The existing bulk oxygen tank will remain.


Fuel oil:

New fuel oil tanks/pumps/filter/piping serving the new generators and boiler will standby fuel needs. This equipment will be placed in new addition and allow for expansion of central plant. 


Fire Protection:

Close coordination will be required between the City, the Owners Insurance Underwriter and the Design team. A new fire service will serve the existing hospital, this addition, and the Medical office building.
A new electric fire pump will serve the new addition and existing facility. There will be standpipes with floor control valve and drain in each stair tower that shall serve each floor. They will be extending a new fire line to serve the existing Hardener Building. They will also extend a new fire line to connect into the existing fire main located in the existing hospital.
The system will provide fire dept. connections, fire pump test header, and indicating valve. Relocate existing fire dept connections impacted by this project. The lower level will be fully sprinkled to Ordinary Hazard Group 2.


Electrical System Description:

The existing hospital is served by two 36KV primary services.  Each service originates from separate substations.  There are two 5MVA transformers that serve the hospital.  Both transformers are energized and share the load of the hospital via a 4160V main-tie-main switchgear lineup in the lower level of the existing facility. The existing maximum load served by the two transformers is 4.4MVA. 
Normal Power service for the addition will be an extension of the existing main-tie-main 4160V switchgear located in the lower level of the existing facility.  A single 4160V feeder will be serve a medium voltage load interrupter switchgear lineup located in the lower level of the addition.  The four feeder switches in this switchgear will serve the two new 1500KVA double ended unit substations.  Space will be left in the lower level of the addition for a future new 4160V vacuum circuit breaker line up.  This future 4160V gear shall be installed when the 5MVA transformers are replaced.


Emergency Power:

The new addition shall include two new 1000KW generators and new paralleling switchgear.  The parallel switchgear was sized to include the addition of one future 1000KW generator. 

Lighting System:

Not completely designed yet. Energy saving luminaires.

Building Envelope & Façade: 

The Specifics on the building envelope are still being developed
Most will be 8” CMU with rigid insulation & a 2”stone veneer. Some places will be aluminum siding panels, and some brick veneer to match the adjacent Harder Building. Masonry is not load bearing; they are for the veneer.

Structural system:

The structural system for the Saint Vincent Health Center Infill Building consists of a steel frame structure supported by deep foundations.  The current roof/future third floor along with the ground and first floors are framed with a 4” concrete slab on a 2” composite steel metal deck spanning between composite wide flange steel framing.  Steel beams and girders carry gravity loads to steel columns supported on concrete caissons.  Special design features include transfer girders located on the roof / future 3rd floor to create large open spaces at the new operating rooms, steel bents cantilevering 40’ at the front entry, and permanent drilled solider pile and lagging walls to support deep excavations adjacent to existing buildings. 

Roofing system:


The Roofing system of the Saint Vincent Medical Center Infill Building is composed of W18x35 & W10x12 beams, W24x55 & W18x40 Girders. The roof structure will be steel composite decking with a concrete roof. This roof is designed to be the possible 3rd floor in the future, with columns of the existing structure sized for the expansion of 3 additional floors in the future.

 

Sustainability Features:

Requesting more information on this topic.

This project is a LEED certified project with the hope of attaining a Silver certification.
The Structural structure of the building is designed with the possibility of adding 3 additional floors in the future. New columns would line up with the existing column below them. These columns are size larger than need for the 3 story structure but are designed that way for the possibly 3 story addition.

There will also be Solar shades to block some of the suns ray from over heating the building.

In the basement of this new building they are putting in a new state of the art Central MEP Plant that will replace the entire MEP services for the entire complex of buildings. This plant will be more efficient than the complex's existing one.
