The GCMC C&E wings are a 148,000 square foot addition to the existing hospital. The architectural objective of the addition was to develop a “fresh new exterior aesthetic that is respectful of the original façade of the old hospital and reflects a state-of-the-art medical facility image to define the Geisinger brand” (BDA Architects)

​

The exterior of the building is comprised of dark and light metal panels with glass curtain wall interspersed. The existing portion of the expansion is clad in dark brick.

​

The interior of the building is a closed floor plan consisting of patient rooms, procedure rooms, and offices for medical personnel.

Building Enclosure

  • Facades:

    • Typical CENTRIA Formawall dimension series insulated smooth white and off white exterior wall panels

    • Brown and grey brick veneer with grey mortar

    • Aluminum window and door frames

    • Cast stone window sills

    • Grey aluminum composite exterior wall panels, clip and caulk installation

    • Thermally broken aluminum curtain wall system with 1” insulated safety and spandrel glass TYP (tinted and untinted)

​

​

  • Roof

    • Ballasted roof system with stone ballast over black EPDM membrane roofing with 5” of extruded polystyrene insulation underneath. Roof structure is a poured concrete floor slab on metal deck 5 ½ inch total thickness 2 hr fire rating.

    • ¼” per 1’ roof pitch

  • Construction

    • The GCMC C&E wing expansion is a 4 story overbuild on top of an existing and occupied emergency room department. Construction occurred from 2012-2015 and cost 97 million dollars. Partial demolition of some areas in the existing hospital was necessary and as such, demolition plans were provided by the architect. The project was designed and bid as an IPD since the client and engineering team have had prior history of working together. Construction management services were provided by Alvin A. Butz inc.

​

​

  • Electrical

    • The expansion is supplied with three phase power from the grid through a central electrical room located in the basement of the main hospital. There are breakers that allow the supply of 120/208V and 277/480V power. Operating rooms and other procedure rooms have individual breakers assigned to each room. Electrical systems include complex controls, communications, and backup power systems to accommodate medical functions. There are backup generators on the roof of the E wing to provide power to essential systems during an outage. There is a lightning protection system comprised of a lightning mast and cable that directs the electricity to ground to protect against electrical surges.

  • Structural

    • The Geisinger Community Medical Center C & E wing expansion is a steel framed system. The image below shows an isometric view of the entire structural system for the expansion. The main gravity system is comprised of concrete slabs on metal deck which are composite with the supporting steel beams and girders that frame into steel columns. The steel columns bear on reinforced concrete spread and strip footings. The reinforced concrete strip and spread footings are typically poured directly on to the shallow bedrock that is available at the site.The lateral force resisting system is comprised of a steel braced frame system with both diagonal and chevron braced frames. C wing has been designed to accommodate 7 structural floors above the first and E wing has been designed for a total of 6 structural floors above the first

  • Lighting

    • There are daylighting controls and occupancy sensors as well as an automated lighting zone schedule that adjusts light levels depending on the day of the week and total occupancy. There are a combination of surface mounted and recessed fluorescent troffers throughout the building. Some of these fixtures are also on an emergency power circuit so that they can be used in the case of a power outage. In each patient room there are 2x2 troffers, 6” recessed downlights, 5”x5” nightlights, and a 4’ wall wash fixture.

​

​

​

  • Mechanical

    • The mechanical system for the GCMC is comprised of a Variable Air Volume system that provides individual temperature control at each individual room.  The equipment that makes up the VAV system for the hospital consists of: energy recovery units, air handling units, centrifugal liquid chillers, VAV boxes, unit heaters, exhaust fans, fan-coil units, return/supply fans, humidifiers, and freeze protection pumps. Split system air conditioning units service electric and data rooms throughout the building

​

​

  • Fire Protection (active and passive)

    • structural members have been spray fireproofed to meet the 2hr minimum fire rating required. The concrete on metal deck meets the minimum thickness required for an unprotected 2hr fire rating.

    • There are fire dampers and firestopping sleeves throughout the MEP system to prevent fire propagation.

    • The entire expansion is sprinkled in accordance with NFPA Pamphlet #13, the IBC, the owner’s insurance carrier, and the local fire department regulations. The sprinkler system is a wet pipe system with upright or hidden sprinkler heads throughout the system.

​

  • Transportation (elevators etc.)

    • There are eight elevators located throughout the expansion. These elevators are large enough to accommodate hospital beds so that patients can be transported around the hospital.

 

  • Telecommunications

    • Nurse Call system throughout all patient floors with control panels. The nurse call system is integrated into the emergency power system as it is considered an essential system for operations.

    • fiber optic communications system for Voice/Data.
