Click here for a pdf version of the breadth options. These options are a cost and schedule analysis and a study of the impact of moving the mechanical system. This is also shown in html format below.

BREADTH OPTIONS

Bread Study 1:  In-Depth Cost and Schedule Analysis

This breadth study will focus on the scheduling impact and cost-related issues that will be impacted by the proposed structural changes. The notable scheduling changes would involve the additional time that might be needed to excavate for a sub-basement level if it is needed.  Also, the different procurement and erection times will need to be considered for the steel design, instead of post-tensioned concrete. Particular attention will be paid to the critical path.
Cost analyses will be conducted separately for the increased revenue that might be possible if an extra story is gained and the additional cost of labor and materials to implement the proposed building alterations. Additionally, the impacted construction time will be considered before directly comparing revenue to cost.  The owner is unable to profit from a building until construction is complete so small revenue gains may not outweigh scheduling delays.
Professionals in the field will be contacted to help provide industry and area specific cost and scheduling information instead of just using RS Means as the only source of information.

Breadth Study 2:  Mechanical Equipment Movement Analysis

This breadth study will focus on the movement of the mechanical equipment to the basement or sub-basement to free up the penthouse space to produce more revenue due to the height restrictions in Washington D.C.  First, the mechanical equipment will need a way to draw outside air to condition the spaces.  It needs to be determined that Washington, D.C. will allow sub-grade mechanical equipment.  The mechanical ductwork will need to be re-designed due to the move.  This will be more of an architectural study as to placement of these ducts since it is assumed that the demand will not increasing, unless the extra floor is created (addressed below), and therefore, the ducts do not need to be resized, only re-placed in the building.  Waterproofing is another issue due to the high water table next to the river.  This will also be considered and detailed for the move.

Depth Related Study

If the extra floor is a viable option, a brief study will be performed to ensure that it is possible for the building to house and supply the additional mechanical and electrical load and equipment.  Also, if time permits, a brief study on the effects of the mechanical equipment move on the occupants will be completed including acoustic and vibration effects on the floors above.

MAE Option

Also considered in this re-design will be the use of computer models to supplement design.  This computer model will take into account information learned from the Computer Modeling of Building Structures masters-level course.  This model will at least be used for aiding the design of the lateral-force-resisting system.  Using semi-rigid diaphragms for the floors, and 3-D beam and column elements that take into account flexural, shear, axial, and panel zone deformations, the lateral force analysis will consider inherent and accidental torsion, as well as P-Delta effects.

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 Kimberlee McKitish. 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.
