But sometimes they do get built on time and/or on budget. The Weitz Co. recently was part of the Clark-Weitz-Clarkson joint venture that delivered the 1.1-million-sq-ft single-terminal Kansas City International Airport project in 2023 on time for $1.5 billion. ----------------------------------------- The Authority would like to replace their current Public Address and Flight Information Display Systems. The PA System replacement will include new head-end equipment, software, amplifiers, ambient noise sensors, and microphones. Existing speakers and cabling will be re-used. The FIDS replacement will include new head-end software and tugman input devices. Existing monitors, LED Displays, DDCs, and peripherals will be re-used along with the associated network cabling.
