Proposal

Construction Management Breadth:

The alternative system will have an effect on both, the cost and critical path schedule of the project. It is possible that the alternative structural system will take longer than the current structural system to be constructed, due to the fact that concrete take longer to dry and be finished than steel does. According to the cost estimate of the actual project, building Tysons Overlook out of concrete structural system will cost a lot less than the current steel structural system. Also, taking into account the cost added to the current system to fire proof it, which will not be included in the alternative structural system, forcing the cost to be reduced as well. The cost and schedule data will be prepared for the spring semester to determine the feasibility of the alternate system.

Acoustics Breadth:

Sound transmission through walls and floors are a big factor for the comfort of occupants especially in hotel buildings. Switching the structural system from steel to concrete will help reduce the amount of sound transmitted through the walls and the floors of the hotel rooms. An acoustical analysis of a typical floor in the building will be performed for the current design as well as the proposed design to ensure that the STC values do not exceed the limits. In addition, other ways of reducing the noise transmission between rooms will be investigated.

Structural Depth:

The proposed solution for Tysons Overlook’s steel structural system design is concrete structural system with flat slab design to resist the gravity loads and moment framed system to resist the lateral loads acting on the building. To help maintaining the same stairs/elevators configuration of the building, the bearing walls will be designed to be located where the current braced frames are. The design of the flat slab system will be based on Chapter 13 of the ACI 318-11 building code requirements for reinforced concrete, equivalent frame method. Analysis for the gravity loads will be completed on the computer program ETABS. Different live load patterns, including full live load on all spans, full and half live loads on adjacent spans, and 75% full load and no load on adjacent spans will be investigated.

The floors’ gravity loads will be determined based on the self-weight of the new structural system based on the members’ sizes, and superimposed dead load assumed based on an educated assumption. The current gridlines systems will remain the same with additional lines added to them to allow the reduction of the spans.

Revised Proposal

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 Eman Elshahat. 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.
