Thesis Proposal – Mechanical Systems Project Proposal

Thesis Proposal - Executive Summary (.pdf) (Original Post 12-18-2007)

The proposed thesis is the replacement of a traditional overhead mixing system with a combination of both underfloor air distribution, and sidewall displacement ventilation systems. The UFAD redesign is proposed for the gate hold rooms located on the south side of level 2. The sidewall displacement design strategy will be incorporated on the airside concourse located in the same area.

The first breadth topic of the proposed thesis is an evaluation of the acoustical characteristics of the space.  The existing design employs both sound attenuators and duct lining to reduce the acoustical impact of HVAC noise.  Since the alternative mechanical design will result in lower air velocities, the possibility exists that these acoustical treatments will no longer be required in these spaces.  The proposed acoustical analysis will also look at other noise factors within the space; including the operation of jet engines outside, as well as the noise from general activity inside the terminal.

The second breadth topic will evaluate either construction management or architectural aspects of the same spaces.  The addition of a raised floor will be required to accommodate the proposed UFAD system.  This has obvious cost and scheduling impacts that will have to be considered in the analysis.  At the same time, this new floor system will also have architectural impacts on the space.  Consideration will have to be given to accommodating this new floor system without significantly affecting ceiling heights in the spaces.  Furthermore, the raised floor will have to make a smooth and level transition to areas that will not include a raised floor.  This will likely require altering some floor elevations in other areas.
