Underground Stations & Tunnels

Often KPFF takes on the challenge of leading the structural design of underground stations, tunnels, and transition structures for major transit projects. Our experience includes deep slurry wall design, top-down and bottom-up construction, and cut-and-cover tunnels. Our creative engineers have developed construction phasing plans that avoid surface street closures and utility interruptions in dense urban environments. We have successfully delivered these projects using a variety of delivery approaches, including design/bid/build and GC/CM.
