Architecture

The center for the built Environment and Infrastructure Studies building acts as laboratory for sustainability in design and engineering by controlling the daylight elements and energy efficiency. The building creats a link between two different environments; the urban context along Perring Parkway and the natural landscape of the Herring Run. CBEIS was design to create a dynamic environment and strong connection between several buildings in Morgan State University campus. Furthermore, it works as an exchange of people, ideas, departments and contexts that promote human interaction and social engagement. All of that was formed by the atrium that exists along the middle of the building. The atrium runs the length of the building acting as internal street as it does the following:

This internal street aligns with the major interior circulation of the neighboring Mitchell and Schaeffer engineering buildings, thereby creating a strong connection to the other engineering disciplines at Morgan State.

The internal street formally displays all the major disciplines of CBEIS and affords informal interaction among the people using the building or even those who simply move through it.

Internally, the interior street also acts as a daylighting device, delivering natural light to the offices, classrooms and studios on three levels while controlling direct light and heat.

The spaces of the building are shown in the plans below:

Zoning

Because the building is owned by Morgan State University, a Maryland state agency or institution, it is not required to meet any local zoning requirements.

Building Envelope

The building used Arriscraft Renaissance masonry units, cast stone trim, curtainwall, storefront, 4 mm Reynobond composite aluminium panels (3 colors) see Figure (1) .

Roofs – 4 ply built-up roofing with SBS cap, polyisocyanurate insulation, vapour barrier, gyp sheathing on metal deck
Terraces – single-ply white TPO polyisocyanurate insulation, pavers and vegetated roof trays

Sustainability Features

CBEIS established a LEED gold certification for its energy efficiency and advanced lighting systems as it used the following systems:

Four types of daylight harvesting systems
Two green roof systems
Rooftop photovoltaic (PV) panels with curtain wall
Gray water system
Solar hot water
Natural ventilation

Construction

Morgan State University has developed a 5.9 acre site, next to its existing Mitchell-Schaefer Engineering Building. The university put a strong sustainability and design goals to create a functional, maintainable and attractive facility that will serve the University well for several decades. The University required innovative design which achieve a minimum LEED Silver certification. The building consider a university academic building that has one floor below grade and three floors above grade that has a 126,515 sf gross area and a total of 257,004 sf site area. The construction budget target was about 45,000,000 dollars. The design was began in December 2007 and the construction was started by February 2010 and finished in May 2012. The university proposed construction of the Center for the Built Environment and Infrastructure Studies to co-locate physically the Department of Civil Engineering, the Institute of Transportation Studies, and the School of Architecture and Planning. The goal was to design an attractive and functional theme building for the campus which serve as a gateway to the campus for vehicles from the northerly direction; to reflect the synthesis of architecture, civil infrastructure, and transportation, and, at the same time, emphasize and make a statement to the community that Morgan State University is fulfilling its obligation regarding its mission as the designated urban university for the State of Maryland.

Structure

The bay sizes consist generally 30 feet on center column grids in North-South direction and ranging from 30 feet to 38 feet in East-West direction. The first floor framed except seismic simulator area are 14” thick two-way flat plate concrete supported by up to square concrete columns. For Seismic simulator floor, it is designed for load and lateral forces and 48” thick slab supported by concrete walls and columns. The floor and supporting structure is isolated from surrounding structure to minimize vibration transmission into building structure. All other framed floor area at this is 2½” thick normal weight Lithocrete concrete on 3 composite deck supported by composite steel beams spaced at maximum 10 feet on center and steel columns.

Mechanical

Air handlers are variable air volume (VAV) type, with medium pressure supply air distribution to VAV air terminal units that include hot water reheat coils. Cooling is provided by the existing chilled water plant, with a design temperature rise of 16°F. Heating hot water is generated by central steam. Heating and chilled water distribution is variable flow.

Electrical

The primary service is obtained by extending the two existing medium voltage, 15 KV feeders, N5 and N6 that serve the North Campus. These two feeders is extended from the Man-Hole II (MH-II) to a new medium voltage switchgear to be installed outside the new facility on eastern side of proposed building. These new extension feeders is utilizing two sets of 3 No. 2/0 AWG 15 KV cables plus one No. 1/0 AWG ground cable in a Two-way 4-inch duct bank, with a spare duct for future. The new medium voltage switchgears shall be suitable for loop type distribution, and is feeding the main power transformer through a three-way switching bank. Secondary Distribution Service.

The secondary power service is at 480/277 VAC, 3-phase, 4-wire system, that is derived from the above said primary service through a new pad mounted, liquid cooled power distribution transformer, to be installed outside, also on the eastern side of the proposed building, to feed a new low voltage 480/277 VAC, 3-phase, 4-wire switchboard, that is installed inside the main electrical room. It is estimated that a 1500/1995 KVA, 13,200-480Y/277VAC, 3-Phase, 4-Wire transformer is required to serve the electrical power requirements of the CBEIS.

There are two closets per floor from first level to third level. These closets will house the lighting and receptacle panelboards required to serve the lighting and receptacle circuits of corresponding floors. Necessary disconnect switches, and 480 VAC – 208Y/120 VAC dry type auxiliary step-down transformers that will provide power to the 208Y/120 VAC panelboards. Each electrical closet is approximately 14’ x 10’ in size.

Lighting

Three types of lamps were used in the building, fluorescent, metal halide lamps, and LED’s. All spaces has occupancy and photo sensors to detect the motions and lighting control. Dimming systems are located in class rooms, labs and studio.

Fire Protection

The Center for Built Environment and Infrastructure Studies (CBEIS) is provided with a combined wet type sprinklers and standpipe fire protection system. Sprinkler heads for the wet pipe sprinklers system is provided throughout the facility and the heads will be placed at the center of ceiling tiles. The standpipe system is provided at all egress stairs. The system is designed and installed to comply with all applicable codes.

Transpotation

There are two – one 3500 lb capacity, one 4500 lb capacity.

Ther are three exit stair locations.

Telecommunication

Lower Level has 1 Main Telecomm Room. Levels 1, 2 and 3 each have two telecomm rooms. There is wireless connectivity throughout the building. There are hardwaired telephone and data connections in all spaces.
