William P. Hobby Airport West Concourse Expansion—Houston, TX

This 280,000-SF project consisted of a five-gate concourse addition including new Federal Inspection Services and expansion of the Southwest Airlines ticketing lobby. The passenger security checkpoint was also increased by the addition of six new screening lanes. The overall expansion increased Hobby International Airport’s physical footprint by more than 40 percent and is the first international terminal for Southwest Airlines adding service to Latin America and the Caribbean. Moye Consulting provided services to design and administer upgrades to the Airport’s data network and communications systems. Work was phased and temporary construction required to maintain existing operations and passenger movements during construction.


In addition to designing data network infrastructure, Moye Consulting provided design for public address and MuFIDS systems. Key components included communications switches; servers for network and telecommunications interface, input module and program source, amplifiers and speakers, ambient noise sensors, digital microphone stations, and visual paging displays.


Of key importance to the client was the ability of airport staff, airline personnel, concessionaires, and patrons to understand public announcements. To assure the quality of the public address system, Moye Consulting digitally modeled the concourse and introduced a typical background noise profile via audio modeling software. The result was a discreet qualifier of sound quality and intelligibility in terms of the Speech Transition Index (STI). Moye Consulting merged the resulting profile with the physical concourse layout developed in Revit to determine the most appropriate locations in which to place speakers.
