architecture
- Design and Functional Components - Coalport Medical Center is currently under construction in the Mid-Atlantic Region as an addition to its’ existing hospital. This addition includes outpatient Behavioral Health and Pharmacy wings. The main focus, architecturally, is to blend this addition into the existing architecture as it upgrades all interior medical equipment and technology to meet modern standards.

building enclosure
- Building Facades - The building facade will be integrated into the existing portion of the hospital. Brick veneer will be the majority of materials similar to the original building. Pilaster will add depth and extra texture to the wall allowing for separation. A minimal amount of exposed sheet metal flashing will match that of the roof to tie in the multiple stories of the facade. Large window system in the middle part of the addition, with strategically placed shading canopies prevent excess solar gain in the corridor areas.
- Roofing - The roofing system is a combination of thermoplastic polyolefin (TPO) membrane, dens-deck sheathing, metal roof deck, and R-34 polyisocyanurate insulation. Proper slopes are tapered into roofing system to allow for adequate drainage. There are no skylight issues that are needed to be cared for, however all three air handling units will be located on the roof. Adequate structural design, extra beams and channel skids, are placed to support these pieces of equipment. Where there are vents and roof drains proper flashing and water barriers are installed as per details to ensure no leaking.
- Sustainability Features - Even though LEED credits were not tracked or designed for on this project, some forms of tangible sustainability can be found. Sustainable features in this building include passive and engineered systems. Passively, manually operable windows inducing natural ventilation are located in all exterior rooms. A large amount of natural lighting is able to reach into the new addition due to strategically sized windows. Variable Refrigerant Flow (VRF) boxes are placed in offices to allow for personal customization of temperatures within their respective spaces.
Construction
The medical center owner is using a design-bid-build delivery method. They contracted out the design to JPT Architects, who houses its’ own Architects, Interior Designer, MEP, and Fire Protection engineering. JPT Architects then subcontracted Keller Engineers for the Civil, and Structural engineering. Construction is projected to begin in the middle of October of this year, and be completed roughly a year later in November of 2017. Inclement weather at the beginning of the schedule during the winter months adds a significant threat of delays. This project has no issue of site logistics problems, or an excess of utilities that could threaten the length of construction. Major construction sequence events include, Design, Excavation, Foundation, Superstructure, Exterior Façade, Interior Building Systems, and Final Inspections.
Electrical/lighting
The existing First Energy primary distribution feeding the hospital enters the Campus off of the main access highway where it transitions from overhead distribution to underground for approximately 770 feet in concrete encased conduit where it connects to a sectionalizing cabinet and a utility owned transformer. The secondary 277/480V, 4000A service enters the building underground feeding Switchboard MDB. Currently the first energy primary distribution feeding the utility owned transformer fall within the proposed building footprint and will need to be relocated. The existing 277/480V, 4000A service entrance switchboard ‘MDP’ and the 1000 kW, 277/480V emergency diesel generator have adequate spare capacity available to support the proposed new load.
MEchanical
Multiple Variable Refrigerant Flow Systems will be installed to condition the new addition being added to the existing hospital. Each system will consist of an air cooled condensing unit cluster located on the roof serving multiple indoor units throughout the addition. The VRF system will be capable of handling both heating and cooling throughout the building. Indoor units will vary from ceiling mounted cassettes, ducted horizontal concealed units above ceilings and wall mounted units. Total cooling for the VRF system serving the new addition will be approximately 100-tons. Basis of design is Mitsubishi City Multi with Hyper Heat. Ventilation air will be supplied through three roof mounted, 100% outdoor air units installed on the new additions. These units will be self-contained, dx cooling and electric heating units. Supply air will be ducted throughout the new addition to serve code required ventilation to the spaces. Basis of design is Mitsubishi PremiSys.
structural
The existing structure is cold formed steel superstructure with strip wall footings along the outside perimeter and shallow spread concrete footings in the interior. The strip foots are at a constant two feet wide and one foot thick, with three #4 bars at 48” on center. All columns are hollow structural steel members ranging in sizes from HSS10x10x0.3125 to HSS4x4x0.3125. Beams and joists are wide flanged steel beams. Design dead and live loads are based off of IBC 2009. Floor slabs vary between 4” and 6” concrete slabs on top of steel decking sized at a minimum 20 gage and 1-1/2” depth.
fire protection
A 4” fire service shall be extended to the new addition from the sprinkler pump room where it will pass through zone valve assemblies prior to being distributed. The building will be provided with a 100% hydraulically calculated automatic standpipe sprinkler system. A 4” standpipe will be installed in the North and South stairwell with fire department connections installed at each intermediate stair landing. Sprinkler head types located throughout the facility will be quick response, fully recessed/concealed type heads with white cover plates. The sprinkler heads will be centered in the ceiling tiles. There will be three new zones serving the new addition. All structural columns and beams get a minimum of one-hour spray fire proofing. Columns and beams located in the pharmacy section of the addition will receive a two-hour spray fire proofing.
demolition
There is a fairly decent amount of renovation for this project. Out of the 68,800 square feet, 10,000 will be demolition and renovation. This is not a complete tear down, but more of a replace systems and rearrange room layouts. There is no major health issues from the demolition whether it be from asbestos or lead based paints. There is always a more strict control of demolition when in a hospital as to not disturb current patients residing there.
