General Description:
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. For an explanation of this capstone design course and its requirements click here. |

User Note:
While great efforts have been taken to provide accurate and complete information on the pages of CPEP, please be aware that the information contained herewith is considered a work‐in‐progress for this thesis project. Modifications and changes related to the original building designs and construction methodologies for this senior thesis project are solely the interpretation of Rachel Gingerich. Changes and discrepancies in no way imply that the original design contained errors or was flawed. Differing assumptions, code references, requirements, and methodologies have been incorporated into this thesis project; therefore, investigation results may vary from the original design. |

Executive Summary |
|
| |
The Duncan Center is a premium office building located in Dover, DE. There are a total of six floors with the building reaching an overall height of 93’-0”. Open flex office space is located on the first four floors, a reception and banquet hall on the fifth floor, and a penthouse holding the building management offices on the sixth floor. Small electrical and mechanical rooms are also located on the sixth floor with the larger electrical and mechanical room located in the basement along with storage space. Balconies augment the fourth and fifth floors and the overall structure is crowned with an arched penthouse. |
|
| |
Structural steel frames the building with a composite metal deck floor system and a moment connected frame lateral system. This proposal presents the redesign of the building to a potentially more economical solution of a concrete structural system with a two-way flat plate conventionally reinforced floor system and a concrete shear wall lateral system. After completion of the proposed system redesign, the two systems will be compared to determine which system is more suitable. |
|
| |
In order create a more complete comparison between the two systems; two breadth studies affected by the system change will be performed. The first breadth study will be in acoustics with regards to the performance of the floor systems in sound transmission and reverberation time for the fifth floor banquet hall. The second breadth study will be in construction management to compare the cost and duration of schedule between the existing system and the proposed. |
|
| |
After the proposed work presented is executed next semester, Spring 2008, and the final results will be presented in a final report and formal presentation. |

Breadth Topics
| |
| |
Acoustical Breadth
| |
| |
The fifth floor of the Duncan Center houses The Outlook Center, an elaborate reception and ballroom space available for rent to the public. As the ballroom is positioned directly above office space available for rent, an acoustical sound transmission of the floor system and a reverberation study will be performed between the two systems. The reverberation study will be performed accounting for change in the floor system and dimension changes to the spaces based on column and moveable partition locations. Contribution of the results of this study will be utilized to determine which system performs the best acoustically under the given conditions.

Construction Management Breadth
| |
| |
As the primary reason for selecting a different floor and lateral system is mainly cost and schedule driven, a comprehensible analysis of both will be performed and compared for the two systems. The cost analysis will include costs related to schedule, labor, equipment, and materials. A construction schedule comparison between the existing structure and the proposed will also be analyzed from time of the beginning of the steel fabrication process or the start of foundation construction, whichever comes first.
