Depth (revised) The focus of this report is to alter the lateral resisting systems of the DH. The proposed lateral system will utilize reinforced load bearing CMU walls. This system will consist primarily of a combination of Concrete Masonry Units (CMU) load-bearing wall and non load-bearing walls. All reinforced CMU load-bearing walls will be continuous from the first floor to the roof in both transverse and longitudinal direction. The floor system will be composed of hollow core precast concrete planks. Changing the lateral system from moment frames to reinforced load-bearing CMU’s will result in simpler and easier frames to construct. Frame stiffnesses, and lateral movement; and both direct shear and torsional shear will be computed in the lateral system analysis to ensure the safety of the building.

Breadth I: Cost and Schedule Analysis (revised)
Due to the redesign of the new lateral system; a cost and schedule impact will also be undertaken to determine the effects of the alterations. Including in this breadth will be estimates on the prices of new materials as well as installation costs and time. The overall cost of the new system will then be compared to the cost of the existing system. In addition, a schedule analysis will be done to determine a new critical path and whether the deadline of August 2010 would still be met. Cost and time changes will be included in the comparison of the two systems.
Breadth II: Architectural Impact (revised)
By implementing a different floor system and continuous load bearing walls from the first floor to the roof, the existing floor plan of the DH will have to be redesigned. This presents an opportunity to also alter the existing layout of the rooms. Currently, the rooms are separated in the middle by a corridor that is approximately 300 feet long. However, changing the layout to an “atrium” like corridor or opening it up to commons areas would promote more student interaction, better ventilation, and an aesthetic environment. The façade may be redesign if necessary. Therefore, an architecture breadth will be included to detail the impact of the CMU load-bearing walls on the overall building.
