Modifications and changes related to the original building designs and construction methodologies for this senior thesis project are solely the interpretation of Benjamin Mahoney. 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.

The final proposal will provide a guide for the research and analyses that will be performed on the Marymount University 26th Street Project throughout the spring 2010 semester.  The topics include the development of a Short Interval Production Schedule, MEP coordination techniques, and the implementation of a green roof. All of the research topics have been chosen to revolve around the critical industry issue relating to increasing efficiencies.

Analysis I: Short Interval Production Schedule Development

The first analysis involves implementing Short Interval Production Scheduling into the interior finishes of the Residential Facility.  The repetitive nature of the activities that are involved in this phase provide a perfect opportunity to try to bring the efficiencies of the “manufacturing process” to the construction industry. 

Analysis II: MEP Coordination

The second analysis involves the investigation into the MEP coordination process.  All of the MEP coordination on the Marymount University Project was done “traditionally” with two-dimensional drawings.  The rise of three-dimensional coordination has introduced another option but has yet to become widely accepted.  The acceptance of the 3D MEP coordination process will be evaluated through a survey of the General Contractor and their subcontractors.

Analysis III: Green Roof Design

The third analysis involves incorporating a green roof into the design of the facilities at Marymount University.  This will require supplementary evaluations on both the structural and mechanical systems of the building.  In addition, Analysis III will satisfy the M.A.E. requirement.

Structural Breadth

Altering the current roof from a white thermoplastic polyolefin (TPO) roofing membrane to a green roof will require an evaluation of the structural system.  The redesign of the reinforced concrete roof will need to account for the additional loads that a green roof will introduce.  Knowledge of structural design will be displayed through numerous hand calculations and the development of new structural drawings.

Mechanical Breadth

The addition of a green roof will also alter the thermal performance of the building envelope.  To take this into account, the mechanical equipment requirements will be further evaluated.  Knowledge of mechanical systems and building envelopes will be demonstrated through various hand calculations and checked with energy modeling software.   

MAE Requirement

Knowledge gained in 500-Level Architectural Engineering classes will be displayed through the design and incorporation of a green roof. The addition of a green roof will increase the building's sustainability and significantly improve the thermal performance of the building's envelope.
