Architecture:

The College of Business Administration building is to be the new signature building of the NAU campus. The 4-story building will feature 14 classrooms, 5 computer labs, 56 faculty offices and a 200 seat auditorium among other things. The first floor features the auditorium and 3 classrooms. The second floor will be home to the dean's suite, the academic advising office, entrance to the café, as well as 4 more classrooms. The third floor will have 28 faculty offices, the MBA office, 3 classrooms, and 2 computer labs. The fourth floor will house 28 more faculty offices, 5 classrooms, and a faculty lounge. This 110, 000 square foot building was designed to attract students and faculty. The building will have state of the art technologies built into it. The CBA has made a commitment to become a leader in sustainable design and green buildings. This is shown by the design of this new building.

Building Envelope:

The exterior walls of the CBA building are made up mostly of curtain walls and pre-cast concrete. As you can see, the first floor, for the most part, is pre-cast concrete. The second floor is also a good deal pre-cast concrete, but it also has some glass walls. The upper two floors above this are mostly glass curtain walls. The exterior walls for the upper floors are made mostly glass as to allow a lot of daylight into the building.

Zoning and History of Site:

I am currently still researching this area.

Structural:

The structural system of the CBA building is a combination of mostly pre-cast concrete and structural steel. The building is broken up into 7 bays of 36' each. The floors are made up of 10" hollow core pre-cast concrete planks spanning between 34"x27" pre-cast concrete t-beams. The first floor walls are pre-cast concrete. The walls above this floor are mostly typical curtain wall construction, with pre-cast concrete in some places. The roof of the auditorium, which is at about the same level as the third floor, is made up of steel I beams ranging in size from W10X12 to W30X116 which will be covered with an acoustical steel deck. The main roof is made up of steel joists, ranging from 18" depths to 24" depths, and steel I beams, ranging in size from W21X44 to W24X76 with steel deck covering. The lateral system is a combination of braced frames and shear walls.

Mechanical:

The CBA building was designed to be a sustainable building. The building will be heated and cooled mostly using passive systems. I do not have the mechanical drawings to go into detail at this time about the actual systems used.

Lighting:

With the high amount of curtain walls and large amount of glass, the building is meant to use the least amount of lighting that is needed. The design of the building allows for a large quantity of the light coming from direct sunlight. The only space that will have special lighting will be the 200 seat auditorium. I plan to look into the types of lighting used here where I get more of the drawings.

Electrical:

I have not received the electrical drawings.

Construction:

The CBA building is being constructed in a way that I will get a LEED rating. The construction must be done in a clean and much guided way in order for a rating to be obtained.

Fire Protection:

With the use of pre-cast concrete throughout most of the building, fireproofing is not a big issue. I cannot go into detail about the types of sprinklers and amount of sprinklers used now.

Telecommunications:

The CBA building will be equipped with state of the art technologies. There are 5 computer labs for students, which will all have high speed internet capabilities, throughout the building.

Transportation:

There are two elevator shafts that run the total height of the building. One is centrally located and one is located on the exterior. There are also stair towers in these locations.

Special Systems:

I am currently researching this area.
