ARCHITECTURE
BACKGROUND:
The former flint journal building, was built in 1924 and existed for over 85 years before renovated. It was enlisted under the National Register of Historic Places in 2013. It is a three and a half story Neo Classical style building. It has an L-shaped footprint with limestone cladding. The original building was designed by Albert Kahn to house the flint journal employees. The exterior exhibits limestone cladding's with classical cornice to emphasize the entablature of the building. In 1965 the printing press space was expanded with an emphasized mural on the east facade of the building. The building has been left as is, until acquired by Uptown Reinvestment in 2012.
RENOVATION PROJECT:
The scope of this project is aimed to completely repurpose the historical former Flint Journal Building. The main aim of the repurpose of this building is to maintain and/or restore the historical element within the building and create a contemporary facility that accommodates public health research, clinical labs, class rooms and event spaces. Presently the program of the newly renovated space consists of 90 private offices, 36 computer stations, 16 loft apartments, 6 exam rooms, 6 nurse station and a 6,069sf two story volume. The current design reverences the original character of the building. Enclosure, Mechanical and structural upgrades were required in other to enable the build compliant with current building codes

BUILDING ENCLOSURE
ENCLOSURE:
The L-shaped three and a half story building is fully enclosed with lime stone cladded wall, brick veneer and cmu. It is assumed to have a type IIB construction type. The façade is further adorned with curtain wall panel with vertical exposed mullions on the north façade and a steel cable supported canopy. The facades are organized in bays for visual symmetry with a pronounced off centered entrance. The 3rd and 4th floor consist of rectangular double hung operable windows to aid natural ventilation in the apartment units on the corresponding floors.
ROOFING:
It has a parapet roof type with a metal shield on the flashing surface of the roof and rigid insulation. It is finished and upgraded to be code compliant with the addition of black EPDM. This is a rubber membrane which is low temperature flexible and consist of thermal shock durability. The roof edges are further supported with gravel stops to aid the roof drainage. The outmost finishing of the roof is covered with a parapet backup wall of height 1.5ft.
SUSTAINABILITY FEATURES
Due to the Neo classical and historical presence of the building, most sustainability features are very passive and integrated in the building style. Most window opening in the building are fully operable, which aids with natural ventilation and day lighting. This reduces the demand on the mechanical systems within the building.
The heavy masonry and cladding have a high thermal inertia which helps to maintain a cool interior space within the building in the day time.
PART II
PRIMARY ENGINEERING SYSTEMS
STRUCTURAL SYSTEM:
The college of human medicine has its foundations supported with nominal weight concrete of 3,000psi with a 5in slab on grade with 6x6 WWF . The other floors are supported with floor slabs of 4000psi nominal weight.
Reinforcing bars ASTM A615, Grade 60 are utilized for support with welded wire fabric ASTM A 185 around each column and slabs. Wide flanges and tees, grade 50 are utilized to create a ridged support. All other angles, Channels and Plates are of grade 36. All structural bay spacing’s are about 16ft apart
The Floor deck has a composite metal floor desk of grade 40 with G60 Coating, The non-composite metal floor desk also has a G90 coating with grade 50. While the roof decking is 1-1/2 deep type B (wide rib) deck with grade 33 and G90 Coating to prevent erosion and water entrance. The columns also have drop panels type construction.
All design loading are added on occupancy category II .Wind loads, snow loads and Seismic Loads are as per MBC 2009 and ASCE 7-05 codes.
MECHANICAL SYSTEM:
The Building is supplied by four air Handling Units of various capacity based on its respective zone. For cooling processes there is a cooling tower 2 chillers, 2 chilled water pumps and 2 chilled condenser pumps. For heating, there is a 1500Mbh capacity boiler and two pumps at 450gpm each with variable frequency drives.
Two air handling Units with 20,000cfm capacity each serve the 1st and mezzanine floor while two other air handling unit with 3800cfm capacities are serving the 2nd and 3rd floor which would be the apartment spaces. Each Zone comprises of Vav boxes with hot water reheat coils. Fan coils unit are present in spaces with glass facades to temper the space.
The apartment units in the building are served by an energy recovery wheel located on the roof. The recovery unit consist of DX packaging cooling and natural gas heat. Each apartment has its individual baseboard heating at areas with glass. Each apartment also has a heat pump with electric resistance heat. Air is distributed with ductwork work and linear diffuses.
ELECTRICAL /LIGHTING SYSTEM:
The building is powered by a 208Y/120 Voltage distribution for miscellaneous general purpose loads with tenant sub metering. It utilizes a 150KVA single ended substation with UL 891 switchboard construction and molded case circuit breakers.
For emergency Power, a 150KW natural gas generator is utilized in case of power outage. While for life safety and standby loads, automatic transfer switches are utilized. Raceways are provided for classrooms technology infrastructures, voice/data and A/V wiring
The residential section of the building is powered by a separate control panel system with independent switchboard to serve all apartment .Each apartment utilizes a 150A MCB panelboard in individually.
All other fixture requirements within the building are as per NEC 210 codes while all alarms are as per NFPA 72.
All automatic lighting controls are as per ASHRE 90.1. All shell spaces have minimal lighting while apartment spaces have wall mounted vanity light in bathroom, pendent lights in dining areas and under cabinet lighting in kitchen areas.
CONSTRUCTION :
The construction process at The College of Human Medicine started April 2013 and ended November 2014. The delivery methods utilized the Design Build method with guaranteed maximum price. This was carried out by Sorensen Gross Construction located in Flint Michigan.
The construction purpose included the renovation of the existing building and the additions of the apartment spaces on the 3rd and 4th floor of the building. The process was vertically staged as renovation was heavy on the 1st and 2nd floor. The 3rd and 4th floor were completely demolished and re-constructed to be apartment spaces.
