User Note: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 Paul Parfitt. 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. |

Thesis Proposal
The thesis proposal will layout the research and design changes that will be performed next semester. It provides a detailed timeline of tasks to be completed and also describes the two breadth topics that will be explored.

Breadth 1: Construction
With a wood structural system, construction time could be greatly reduced. There is less lead time necessary for wood trusses than the steel system and the constructability is easier. In general, wood is inexpensive when compared to steel and the less labor intensive system would also in turn reduce the cost of construction. The research performed in the next semester will compare both the construction schedule and construction cost to determine if a wood structural system would be a favorable alternative to open-web steel joists supporting a metal deck and concrete slab.
Breadth 2: Acoustics
One concern when using wood construction, particularly in a multi-family facility consisting of luxury apartments, is acoustical performance. Wood is more susceptible to vibration than steel. With the new structural system, the noise barrier created by the 3.5” of concrete is lost and replaced with a subfloor. Because wood trusses will be replacing the open web steel joists, the routing of the mechanical equipment is not an issue. The equipment that was run through the webs of the steel joists in the original system can be treated the same way with the open web wood trusses. In the upcoming semester, a vibration analysis will be performed and research will be performed to provide an adequate sound barrier from apartment to apartment.
