LA Metro Westside Purple Line Extension

PB&A served as Engineer of Record (EOR) for the temporary Support of Excavation for four underground stations comprising the Purple Line Extension. This high-speed rail alternative connects commuters traveling between downtown Los Angeles, the Miracle Mile, Beverly Hills, and Westwood. The design was complicated by the requirement to keep Wilshire Blvd. open as a live thoroughfare over the excavations. PB&A designed concrete decking panels to maintain vehicular and pedestrian traffic while excavation took place beneath.
