Fantastic photos published by LA Metro of the tunneling machine being lowered into Wilshire/La Brea Station for the Purple Line Extension of the metro rail system. PB&A, Inc. has spent the past 4 years designing the Support of Excavation (SOE) systems for all 3 underground stations along Wilshire Blvd. at La Brea, Fairfax and La Cienega, along with the decking systems keeping Wilsire Blvd. live during construction. Kudos to the PB&A, Inc. team; Babak Mamaqani, PhD, PE, PMP, Sandy Soe P.E., and Manuel Linang who have spent most of their waking hours designing and drafting the shoring, and to Pirooz Barar S.E. who has spent the past 40 years dreaming of shoring innovation that makes the impossible, possible.
