Architecture
The Medical College is separated into an East Wing and a West Wing, with a central Link connecting the two wings. The West Wing houses a majority of the research laboratory spaces, while the East Wing houses educational spaces. The 4-story West Wing contains around 65,000 sq ft with gross anatomy labs, state-of-the-art clinical skills and simulation suites, research labs and a vivarium. The 4-story East Wing contains approximately 118,000 sq ft with a large auditorium space, lecture halls, classrooms, study rooms, a library, and administration spaces. The Link is 2-stories high and contains a lobby and café area for the building occupants.
The Medical College has architecture that matches university buildings in the surrounding area. It is clad in brick, stone, and glass curtain wall systems. The brick and stone are a tan, dove gray, and charcoal coloring. The wings are made up of mostly brick, stone, and glass windows, while the Link is made up of glass curtain wall systems. These curtain wall systems allow for natural daylight to enter the Link, which houses the lobby area for The Medical College. Landscaping around The Medical College includes green space, made up of gardens, to provide the students and staff diversity from the city feel where The Medical College resides in.

Construction
May 2009-October 2011
The total building cost was $120 million dollars and it was completed using a design-bid-build delivery method. There was no general contractor involved in the construction of this building. The construction management team was headed by Quandel Construction Group. Quality control was important for the construction of The Medical College. Building construction followed the intent of the owner to use a majority of local and recycled materials when possible. Quality assurance was needed for these materials as well as the glass being used for windows and curtain systems. The biggest challenges during the construction schedule came from the integration of the MEP systems with the rest of the building.
Structural
Foundation:
The foundation of the West Wing is a mat slab foundation that is 4' thick. It is designed for a soil bearing pressure of 3000psf and sits on top of a 2' thick structural fill and a 4" mud slab. 4' of compacted was set in place, followed by 5" slab on grade. The East Wing foundation has drilled caissons that are used to carry loads from grade beams to bedrock below.
Framing:
The Medical College has a composite steel framed system. W-Shape, ASTM A992 Steel framing was used. The sizes of the beams and columns ranged from W8x24 to W14x257.
Lateral System:
The main lateral system consists of fifteen moment frames located in the West Wing, East Wing, and Link. These frames are located near the exterior walls to maximize the lateral force resisted. The moment frames span across the entire building.
Lighting / Electrical
Lighting
The majority of the interior lighting fixtures in the facility utilize energy saving fluorescent T5 and T8 lamps. The use of LED fixtures is used for accent lighting throughout the facility. The fixtures are supplied with high efficiency ballasts. Also, many of these fixtures throughout the building are dimmable. The lighting control system is comprised of occupancy sensors, photocells, and daylight sensors all tied into the Facility Management System.
The exterior lighting system utilizes fluorescent, LED, and the use of HID lamps. The fixtures that illuminate the walkways are mounted low to the ground to produce minimal light pollution. The exterior lighting system is also tied into the Facility Management System.
Electrical Power
Both 208Y/120 Volt and 480Y/277 Volt, 3-Phase electrical systems power the entire building. There are electrical rooms located in each wing housing panel boards and electrical equipment. Receptacles run on 208Y/120 volt 3-Phase. The electrical distribution system is comprised of three switchboards. One is dedicated to the Central Utility Plant, one is dedicated to the West Wing and one is dedicated to the East Wing. Each switchboard has a meter installed to monitor the demand of the facility.
Mechanical
Mechanical Overview
The Medical College is serviced by an off-site Central Utility Plant. This Central Utility Plant contains both central cooling and central heating. The central cooling plant produces chilled water to be used by the ten air handling units, fan coil units, computer room conditioning units, and terminal units. The central heating plant produces both steam and hot water to be utilized by the same mechanical equipment, as well as the fin tube radiation. The building is conditioned by terminal units, free-cooling and air handling units utilizing variable air volume boxes, constant air volume boxes, and diffusers as air delivery methods. Exhaust fans and laboratory hoods are utilized to exhaust out air from the spaces and out of the building. The buildings mechanical systems are controlled from a LONMARK DDC controller at each unit which provides all control functions for the systems. A facility management system was put into place to control all of the buildings heating, cooling, ventilation, lighting, and security needs.
Central Heating Plant
The central heating plant consists of three high pressure steam boilers, six hydronic boilers, VFD
driven hot water pumps, flow meters, control valves, and piping. The central heating plant services the building’s mechanical equipment that requires hot water or steam. AHUs, reheat coils, terminal units, fin tube radiation all receive hot water from the central heating plant. The hot water and steam is delivered through piping loops throughout the building.
Central Cooling Plant
The central cooling plant consists of four 300-ton chillers that have pressure control valves
arranged in a primary pumping scheme, a three cell 800-ton cooling tower, a 300gpm free- cooling plate frame heat exchanger, VFD driven chilled water pumps, control valves, flow meters, chilled water supply, chilled water return, condenser water supply, and condenser water return piping. The cooling tower cells follow a lead-lag relationship. To be more energy efficient the buildings cooling systems are modulated so that the number of chillers, pumps and cooling tower cells that are enabled at any given time vary by the total system tonnage. The chilled water pumps supply the equipment with the designed water temperature at the designed flow rates through the chilled water supply piping.
Air-Side Systems
The Medical College’s air conditioning loads are met by free-cooling, ten AHUs, FCUs, terminal
units and two CRCs each suppling air to the intended zones. The method of air delivery differs for these systems. They use VAV boxes, CV boxes, and diffusers through ductwork as means of air delivery to space.
Seven of the ten AHUs are outside air systems, used to provide the zones they are supplying with fresh outside air. AHU-3, which services the vivarium space is a 100% outside air unit, as that air cannot be recirculated. The AHUs utilize VAV boxes with reheat coils to save energy and reduce the amount of hot water needed to be supplied to each AHU. Some of the AHUs have UV lights installed to ensure the spaces receive conditioned air that meets the design requirements. The AHUs utilize energy recovery wheels for energy savings. They also utilize economizer controls for free cooling and carbon dioxide sensors to regulate the minimum requirements for ventilation based on the occupancy in the space.
Special requirements are in place for the conditioning of some of the lab spaces, simulation rooms, and the vivarium. These rooms use humidifiers to keep the relative humidity levels to design conditions as well as exhaust fans and laboratory hoods to relieve the spaces of the contaminated air.
Fire Protection
2006 International Fire Code Compliant
The building is equipped with a sprinkler and standpipe systems, fire extinguishers, and fire department connection. All structural elements, such as columns, girders, and trusses, have at least a 2-hour fire rating. The minimum 2-hour fire rating was achieved by spray fireproofing.The fire barriers used throughout the building have 2-hour fire rating.
Transportation
Elevators and Stairwells
The Medical College contains an elevator bank and two stair towers in each wing. These provide access to all four floors of the building, and the penthouse. In the West Wing, the stair towers are located on the north and south ends of the building. While in the East wing, the stair towers are located in the center and the south end of the building.
Telecommunications
CAT-6, CAT-6 Data, COAX, and Fiber Optic
The telecommunications systems consist of equipment racks located in the computer rooms that are tied into the Facility Management System that controls the entire building. Fiber optic cables are used. Video surveillance and security card access servers are also included.
