REVISED THESIS PROPOSAL:
The entire Gateway structure above level 3 will be redesigned to accommodate a live load of 100psf, the live load for a circulation space in a museum. The slabs will still be designed as flat plates but will likely experience changes in thickness and reinforcement. As a museum is unlikely to have 10 foot floor to floor heights, the distance between the floors will be extended to 15 feet and floors 8, 9, and 10 will be taken out of the building to maintain the same overall building height, as shown in Figure 4 below. The increased floor to floor height will necessitate a redesign of the gravity columns throughout the building.
Changing the gravity system of the building will have direct impacts on the Gateway lateral system. Taking out several floors will decrease the overall building weight, but the increased floor to floor height will change the story shear at each level. The building will need to be re-analyzed for wind and seismic forces and the lateral shear walls will likely need to be redesigned. The foundations of the building will also need to be considered to see if any changes are necessary.
An architectural breadth will be studied due to the changes in floor plan and floor to floor heights associated with changing the building’s use. All of the apartments in the building will be taken out and replaced with museum galleries. The circulation of people through the museum will also be an important aspect of the architectural breadth. The last part of this breadth will be a redesign of the building façade to more appropriately fit a museum. The amount of glass will be diminished to limit the amount of direct sunlight penetrating the building into the museum spaces. This will be done in an aesthetically pleasing way so as to maintain the architectural significance of the Gateway. A Revit model will be developed to provide accurate floor plans, elevations, and renderings of the new architectural features.
A sustainability breadth will also be studied due to the complete lack of sustainable features on the existing building. The United States Green Building Council’s LEED program will be the basis for the sustainability breadth, with the goal of making the Gateway at least LEED Certified. Based on the LEED scorecard, shown in Figure 5 on the following page, a total of 40 points are needed for LEED Certification. For this breadth the points will be drawn heavily from the Sustainable Sites, Water Efficiency, and Materials and Resources sections. Due to time constraints the Indoor Environmental Quality and Energy and Atmosphere sections will be neglected, though in an actual building design they would be considered. The end result of this breadth will include a detailed design of a green roof system as well as highlight other credits needed in order to gain LEED certification.
