Portland International Airport (PDX) Terminal Balancing and Concourse E Extension

As a subconsultant to HEA, Greenbusch is providing Audio/Video Paging Systems design, Acoustical Design and Environmental Noise & Vibration services supporting a $175 million, 130,000 SF addition to the terminal. The 750 foot long extension of Concourse E adds seven (7) mainline passenger boarding gates and concessions, and includes the relocation of Southwest Airlines from Concourse C to the new areas of Concourse E extension.

The paging system upgrades include A/V support for fire alarm interfacing to the new paging system and board rooms as well as paging systems throughout the expanded terminal and concessions areas. Interior acoustics design includes recommendations for construction necessary to acoustically separate spaces including floor, wall and ceiling construction and glazing types; performance specifications for surface finishes to control noise and reverberation; and recommendations for silencing of ductborne fan noise, control of noise generated by turbulent airflow, diffuser and grille noise and airborne equipment noise. Sound intrusion from aircraft operations was measured over the course of the project, and recommendations developed to control interior sound levels.
