A Medical Office Building for the Primary Health Network (PHN) was designed using the 2009 edition of the International Building Code. This building by PHN is part of an effort to revitalize a decaying area of Sharon, this meant that aesthetic appearance and economic efficiency factored heavily into the design. The primary structure consists of steel columns supporting a joist floor system with concrete on metal deck. Additional Information Requested from Architect.




Occupancy Classification: B

Maximum Occupancy: 780 persons


Historical Requirements


There are no historical requirements associated with this building.


Building Enclosure


The building façade is non-load bearing 8” masonry block up to the third floor level at which point it transitions into a combination of glass curtain wall and an exterior insulation finishing system by the Dryvit company. The main entry features a double height glass atrium. The roof system is comprised of Carlisle Sure-White .060 E.P.D.M. Fully Adhered, membrane roof system on rigid insulation.

The existing electrical systems utilizes a building voltage of 480/277V. The power is supplied at 13 kilovolt amps from which it is stepped down on a 4” pad-mounted transformer to the building voltage. This is then sent out to the elevators directly from (2) pad mounted transformers. From the pad power is also sent out to a main distribution panel for each floor. Transformers receive the building voltage of 480/277V at each floor and step it down to 120/208V to typical receptacle use.




Low voltage occupancy sensors are mounted throughout the building to reduce energy consumption in unoccupied spaces. The building utilizes ten different lamp types, the most commonly used being 8” industrial fluorescent and direct/indirect fluorescent T8 lamps. A variety of LED fixtures were used in aesthetic design to compliment the building architecture.




The superstructure of the building consists four elevated floors consisting of steel bar joists supported by wide flange steel columns and girders. The floor system is comprised of 2 ½” normal weight, 3000psi concrete on 26 gage metal form deck reinforced with 6x6 W1.4xW1.4 welded wire reinforcement. The roof systems consists of Carlisle sure-white .060 E.P.D.M. fully adhered membrane roof system on rigid insulation in turn supported by steel deck. Typical bays are roughly 30’ by 30’ with member sizes of around 24” depth. The building sits on shallow foundations. The lateral force resisting system consists of three Ivany block shear walls located one at the east and west ends of the building respectively, with one also located near the buildings center. Lateral loads are transferred through the façade into the floor diaphragm and then distributed to the shear walls.




The building was constructed by Hudson Construction under a design-bid project delivery contract. The buildings estimated cost, including shell+MEP is $10 million and will be constructed from November 2014-January 2016. The buildings final maximum height is 85’-0” and will have a gross square footage of 78,000. The site location is in the center of Sharon, Pa and as such construction must have as minimal of an impact on surrounding areas as possible.




The mechanical cooling system for the building consists of two 65 ton air handling units and one 30 ton unit. Cooled air is distributed throughout the building via sheet metal duct work controlled by variable air volume boxes equipped with hydronic reheat coils. Both supply and return air ductwork is located in the ceiling plenum on each floor.

Building heating is supplied by two 600MBH natural gas fired boilers. The hot water is regulated via a system of two series 90 hot water pumps capable of a 45gpm flow rate and one 110 gallon expansion tank.



Fire Protection


The building is fully sprinklered, utilizing a class II manual wet standpipe system. A variety of heads are used throughout the building designated by the spaces intended use and primarily include concealed, recessed and upright. The standpipe system has a static pressure of 140psi and is capable of a 1700gpm flow rate.




The buildings primary usage is as a medical office building, as such transportation systems throughout the building will prove critical. The primary mode of transportation comes via two 5,000lb capacity elevators located near the buildings center. Alternative access is provided by two stairwells at the buildings east and west edges respectively and also via a third stairwell located near the buildings center by the elevators.




Telecommunication service enters the building via (3) 4” conduits leading to a single telephone backboard. ¾” conduit runs from the backboard to each floor where it breaks out to individual data outlets. Scope of building telecommunications to be furnished by general contractor after being negotiated with building owner.


Special Systems


The building will be equipped with a CCTV monitoring system. Fixed position interior ceiling mounted dome cameras viewing the building entrances and lobby spaces will feed video to a digital video recorder and displayed on a 19” color monitor.
