Architecture & Building Envelope
The New Administration Building for the University of Maryland, Baltimore is six stories of offices, including the University’s executive offices. This building sticks with the theme of red brick, seen throughout the downtown Baltimore campus. It is a fitting complement to the recently completed dental school, one block away.

The envelope is comprised of face brick, metal wall panels, storefront windows, and a curtain wall on the South, main, entrance. Under the windows there are soldiered bricks as well as a band of soldiered face brick wrapping the entire building on the second and sixth floors and the roof. The curtain wall is twenty seven and a half feet talk by twenty five feet wide. It is made up entirely of glazed aluminum. It begins above the main entrance and underneath is a large building sign. 

On top of the roof sits the elevator machine room and the main buildings air handling units. The roof itself is broken into 3 types, type 1/1A, type 2, and type 3. Below is a table comparing the different types.

PART 2

Construction

The University of Maryland, Baltimore New Administration Building utilizes Design/Build project delivery system. The University holds a GMP contract with Barton Malow and Barton Malow holds a GMP with the Architect and all the subcontractors. Having all contracts be GMP offers some maneuverability, because if the design is a work in progress (Design/Build) then changes can be made to keep the cost under the budget with less of an overall impact to the project. Also, because Barton Malow holds all the contracts there is only one point of contact with the owner. This limits confusion between owner, contractor and subcontractor.

Like most jobs, bids were accepted up until a due date and time. After that, no more bids were accepted for that specific bid package. The contractor who met all the requirements and whose estimate was comparable to BMC’s, was awarded the project. This being public work, many times the lowest bidder is taken, but that is within reason. Extremely low or high bids can be thrown out. One requirement that Barton Malow had to meet is 25% MBE/WBE (Minority Business Enterprise/Women Business Enterprise) participation of total construction. This means subcontractors must either be or employ MBE/WBE businesses. For instance if the mechanical contractor is not minority or woman owned but their sheet metal supplier is, then that counts towards to project. Another requirement is that any contractor with over $100,000 in their budget had to furnish a bid bond, issued by a surety company licensed to issue bonds in the State of Maryland.

Means and methods are found within the following sections.

Structural

Foundation
The foundation consists of many auger cast piles that were 18” in diameter and dug 45’ below surface elevation. These piles were tied into pile caps. There are 5 different variations of caps as well as a few unique pile caps for shear walls, stair wells, and elevator shafts. Grade beams were used to connect the pile caps and will distribute load transferred from the building.

Superstructure
The entire building was constructed of cast in place concrete using a combination of crane and bucket and pump truck. Utilizing post tensioning, a slab thickness of 9 inches was achieved. The tendons, in the North/South direction follow the column lines. The East/West direction is more difficult to see a pattern.

The elevated floor slabs were split in half and constructed in a staggering fashion to allow contractors to work continuously. It meant work did not have to stop while pours were conducted.

The slabs were formed using multi-use plywood and scaffolding the entire floor area. Slabs were poured using a pump truck. The concrete was given 3 days to cure and then the tendons would be stressed. 5 days after the pour, the forms were stripped and reshores were placed underneath, until the concrete reached full strength.

The layout of the columns is pretty uniform throughout the building. Typical bays are thirty feet by thirty feet. Columns followed the same pattern as the slabs. Columns were erected the day after the slab was poured. The column rebar cages, which were fabricated on the ground, were tied in to bent bars coming up from the slab. Unlimited-use, “Doka”, forms were used for the columns. “Doka” forms are much more expensive initially but can be used forever and are much easier to put into place. In the longer run they end up saving money. Crane and bucket was used to pour the column.

Façade

The façade is a combination of brick veneer, aluminum glazing, metal wall panels, and curtain wall. Scaffolding, that extended the entire length of building elevations, was erected for the masons. This led to increased efficiency because, the masons were able to move seamlessly from area to area without having to move scaffold.   
Wrapping around the Southwest corner is an 878 SF curtain wall. This is the main architectural feature and also the main entrance to the building. It starts just after the first floor and extends 27.5 feet high. The main panes are 8 feet 7inces tall and 6 feet wide.

The curtain wall is comprised of glazed aluminum. Accenting the main entrance curtain wall are metal wall panels and more glazed aluminum instead of the brick veneer found on all other sides. Telescoping lifts were used to set the curtain wall after it was framed in during enclosure.

Electrical/Lighting

The electrical system is fed by a 200KW generator set rated 208/120V, 3 phase, 4 wire. This generator feeds dual 15kV switches and steps down to a 750kVA transformer. Areas are lit by various sized fluorescent lights.

Mechanical

The Mechanical rooms are located on the first floor in the Northeast corner of the building. There is an attached room dedicated to the hot water system. On the roof there is a custom made 90,000 CFM Air Handling Unit that services all 6 floors of the building.

The UMB New Administration Building utilizes Forced-Circulation Air-Cooling and Air Heating-Coils. There are 8 glycol air conditioning units throughout the building. There are various heating and cooling terminal units including, finned tube radiation, convectors, electric unit heaters, cabinet heaters, and coils. To control air volume in different zones, this system uses Single Duct Variable Air Volume. The entire system is automated with sensors to monitor and control the environment within a space.

Fire Protection

The University of Maryland, Baltimore New Administration is designed with a wet sprinkler system. The building is broken up into zones based on the floors present. Each floor is considered its own zone separate from each other. Within each zone there must be 100psi of water pressure is available to the most remote area in the system.

Transportation

At the South end of the building is the elevator and stair #1 core. This core serves as the South end shear wall as well. Within the core is stair #1 that extends to the roof of the building as well as two elevator shafts. Stair #2 is found at the North end and also connects to a shear wall.

Telecommunications

The entire building is wired to support telephone and data hook-ups in each office and conference room. There is also expansion possibilities for the 6th floor, which is currently shell space, but may be fit out for offices in the future.

 

 


 About Portfolio: The Capstone Project Electronic Portfolio (CPEP) is a web‐based project and information center. It contains material produced for a year‐long Senior Thesis class. Its purpose, in addition to providing central storage of individual assignments, is to foster communication and collaboration between student, faculty consultant, course instructors, and industry consultants. This website is dedicated to the research and analysis conducted via guidelines provided by the Department of Architectural Engineering.
