The $14 billion modernization program now underway at Los Angeles International Airport (LAX) is considered to be the largest public works program in the history of the City of Los Angeles. The centerpiece of the modernization project is the introduction of a $2 billion Automated People Mover (APM) system. Once completed this 2.25-mile rail line will connect LAX passengers to off-airport transportation facilities for the first time in the airport’s 75-year history. Central to the APM project are three now-under construction “LAX Terminal Core & APM Interface” projects that will link passenger terminals to the new people mover system. The LAX Tom Bradley International Terminal (TBIT) Core and APM Interface project is the largest of the three terminal expansion projects. Austin Commercial selected Gardena, CA-based Xcel Mechanical Systems to deliver a $15 million design-build mechanical and plumbing solution for the project.
