Project Description
DYA provided geotechnical input to replace most of the Tom Bradley International Terminal (TBIT) at Los Angeles International Airport (LAX). The proposed project consisted of the addition of two new concourses, expanding the core building, and other improvements. The footprint of the new structures was more than 400,000 square feet. The new concourses will be approximately 4- to 5-stories high with one to two basement levels. The scope of DYA’s investigation services included drilling borings, performing laboratory tests on soil samples, performing engineering analyses, and presenting the results in a written report. The key geotechnical concerns included seismic criteria, foundation support, excavations adjacent to existing structures, shoring design, staging, foundation settlements, and corrosion potential. DYA provided recommendations for shallow spread foundations, mat foundations, and deep cast-in-drill-hole (CIDH) pile foundations. In 2010, the $723.5-million project achieved LEED Silver certification, the first ever for a renovation project at a U.S. airport.
