Proposal Analysis Summary

Removal of Basement (Construction Depth):

Analysis 2 is to remove the basement from the design of the building. This analysis will be construction based and for that reason it will be a construction breadth. To complete this analysis, I first will collect the data on the real costs the basement was. I will find the costs of the sheeting and shoring, the concrete pour, as well as all associated labor costs and additional materials for the basement. From here I would like to update my Analysis 1 schedule with the decrease in man-hours found by removing the basement. I would again update my total cost loaded loaded schedule and compare both against the current time and cost schedules running for the project.

Mechanical Penthouse on Cafe Roof (Structural Breadth):

Analysis 3 is to create a mechanical penthouse on the cafe roof. To complete this analysis, I plan to first find the total weight of the items that will be placed atop the cafe roof. This system weight will be determined off of the findings of Analysis 1. Since Analysis one is expected to decrease the total system size, much lower weight requirements will be placed on the cafe structure than with the current systems housed in the basement for a forced air system. Once the system weight is found, I plan to increase the beam sizing in the cafe to support the new roof load. I plan to create a STAAD model and perform a structural analysis of my newfound beam system to insure my design is safe. From here I would like to calculate the new costs associated with this penthouse. I plan to add in the increased costs of the larger beam sizes. I also plan to add in the costs to build a penthouse wall around the mechanical systems on the roof. Since the cafe is only two stories high it is easy for passersby to see what lies on the roof. The cafe is also designed to be a very aesthetic portion of the Commons. To tackle this problem, I plan to calculate the costs & structural weight to have the penthouse wall be made of brick coursing. This brick coursing will match the same brick that is located on the higher west wall it will be butted against. This will blend the penthouse into the rest of the building, keeping it from becoming an eyesore. With these newly added structural, material, and labor costs I would like to update both my cost loaded and man-hour schedule. Again I plan to compare this schedule to the one currently being implemented on the project. 

Re-Route Ductwork from AHU-1 Relocation

Analysis 3 is to re-route the mechanical ductwork from its proposed location on the café roof. This requires that all of the original ductwork, as well as the sizing of the ductwork to be re-routed and re-sized.
              To go about this issue, I plan to find a new pathway from the top of the cafe, to the previous connection points for my duct runs. When finding a pathway, it must not interfere with any previously placed duct runs, as well as to not effect finished aesthetics. While doing this, I must also re-size the duct runs to insure that the proper CFM’s are being maintained. Any time that changes are being made to the duct runs for mechanical equipment, it must also be found to be capable of producing enough power for the new runs. If it is found that the units can not push enough air for the new duct runs, the units will be re-sized.
