The Western Expansion projects at Portland International Airport contains the ticket lobby, security screening, baggage handling and baggage claim, mezzanine offices and conference rooms, and a pre-security concessions area. The terminal is being redeveloped and will be expanded to the west with a new roof over the existing terminal bringing the terminal core to approximately one million square feet.
GRI’s project team completed a geotechnical investigation for the PDXNext expansion project. The purpose of our investigation was to evaluate subsurface conditions at the site and develop conclusions and recommendations regarding foundation support, seismic design, site preparation and earthwork, and temporary excavations and shoring.
