STATISTICS
Central Pennsylvania Hospital
Background
Central Pennsylvania Hospital is located in Central Pennsylvania. This project is a Design-Bid-Build project utilizing a Guaranteed Maximum Price. The new addition being added is 65,000 sq. ft. and consists of 5 above ground stories along with a partial basement. The addition is zoned as an I-2 type IB IBC 602 structure following IBC 2015, ICC/ANSI A117.1 2015 and the Guidelines for Design and Construction of Hospital and Healthcare Facilities Pennsylvania Department of Health Division of Acute and Ambulatory Care Rules and Regulations for Hospitals 2018.
Enclosure
The envelope consists of a combination of precast concrete wall panels and glazed aluminum curtain wall panels. There are 9 different wall assemblies, 3 different roof assemblies, 2 types of curtain wall assemblies and 2 types of storefront assemblies for the enclosure on the building. It should be noted that included in the project is the expansion of the central utility plant for the hospital.
Lighting
Lighting throughout the new addition will be primarily 277 V LED fixtures. Fluorescent lamps will be provided to meet functional requirements where necessary. Wall switches will be installed at 42” above finished floor and there will be a minimum of at least one switch per room/area. Multi-level switching will be installed in offices and other locations requiring more than one light level. Lighting in corridors and patient rooms will be controlled to operate at reduced light levels at night. Occupancy sensors will be used throughout the addition except for patient rooms, nurse’s stations, electrical and mechanical rooms and public corridors. LED edge-lit exit signs will also be installed throughout the building.
Architecture
The new addition will tie into the existing conditions for the main portion of the hospital. The architect for the expansion is the same architect that designed the initial hospital, whereas they designed the original to eventually have an addition added. This hospital was built 5 years ago. The building is in the shape of a L, where the emergency department is in the bottom bar of the L. The hospital is mainly focused on performing surgeries with hospital beds to support the facilities. Extended stays by patients are not typically what the hospital is trying to achieve.
Construction
The delivery method for this project is CM at Risk with multiple design assist contracts during the preconstruction phase. The design assist contracts were for the structural, mechanical, and electrical systems as well as use of the VDC department at Benchmark. One aspect of the construction project that is vital to this project is the relocation of the Emergency Department entrance prior to construction. A new entrance needed to be built temporarily because the main entrance is on the side of the building where the new addition is attaching. This was done prior to the start of construction and therefore, I will not be including the price and data in my thesis. Another important aspect of the project is the redesign of the roads, parking lots and loading dock behind the hospital. In order to have sufficient laydown area along with construction management space, several parking lots had to be used to support construction. A road had to be relocated because the original road and entrance were located where the addition is now. The entrance to the loading dock also had to be relocated to the opposite side of the lot to accommodate the construction area.
Electrical
The electrical system for the new addition will be a combination of 480/277 and 120/208 Volt service. The 480/277 Volt service will have 250 amps and the 120/208 Volt service will have a combination of 250 and 150 amps. There are also multiple emergency power services for the building. A paralleling system for the emergency power is also being installed. A new 1,000 KW diesel generator will be added to assist the existing generator at the Central Utility Plant. EL Heim was the design assist contractor that worked with Barton and Benchmark.
Mechanical
The mechanical system for the new addition consists of a mechanical room in the basement, rooftop units and partial supply from the Central Utility Plant. The mechanical system was created using a design assist contract with Benchmark, McClure Company and Barton Associates (MEP Engineer). The mechanical system is designed to handle a cooling load of 300 tons and a heating load of 3,000 MBH. Chilled water will be supplied via a 6” line from the Central Utility Plant and two heat exchangers, two hot water pumps, condensate receiver tank and pumps and controls will be located in the basement mechanical room of the new addition. VAV boxes will be used to help condition spaces throughout the addition; the VAV boxes will be supplied by AHUs on the roof.
Parties Involved
Structural
The main superstructure of the addition consists of structural steel beams, girders and columns. The beams range in sizes from W12x19 up to W21x44. Girders range in size from W18X35 up to W36x150. Columns range is size from W10x68 up to W12x152. The superstructure is supported by a combination of spread footings and piers. The spread footings range in size from 3’ x 3’ x1’ up to 14’ 5 ”x 14’ 5” x 3’ 8” and the peris range from 18” x 18” up to 30” x 50”. The deck for the roof is 1 ½” with typical EPDM roofing and the deck for the floors is 3” composite steel with 3 ¼” lightweight concrete. Support for the screen wall is made up of MC10x25 and HSS14x10x3/8.
Fire Protection
The fire protection system will be a combination of a wet and dry pipe standpipe system. There will be a 6” riser and a 1,000 GPM fire pump installed. The wet-pipe system will be for the interior locations and the dry-pipe system will be used for the new loading dock and mechanical room. The sprinkler contractor is Viozzi Sprinkler. The fire protection system will conform to the latest requirements of the National Fire Protection Association (NFPA 13,14,20), Pennsylvania Uniform Construction Code, state and local authorities and the Owner’s fire insurance underwriters. All floor controls assemblies will be monitored with flow and tamper switches and will be zoned and monitored per floor.
Telecommunications
The new addition will contain centrally located Telecommunications Distribution Rooms (TDR) and will be vertically stacked. The TDRs will house telecommunication, nurse call, multi-media and CATV services. Cables will be a combination of copper and fiber optic cords based on equipment specifications. The security controls will be relocated to the new entrance of the Emergency Department.
Special Systems
Per the specs, it is the responsibility of Benchmark to provide conduit raceway systems for the hardware and controls for door holders, door openers and safety eyes. These will service the CT Scan Suit, Cardiac Catherization Lab and Hybrid Operating Room on the first floor as well as the standard and hybrid operating rooms on the second floor. The electrical contractor is responsible to coordinate location, mounting height and wiring requirements for hardware with Benchmark’s and the manufacturer’s installation requirements.
