Free Webinar – Our Secrets for Design of 2nd / Broadway Station

We are holding, along with DeepEx, a free webinar about “Experience, Design and Analysis of Shoring System for 2nd/Broadway Station” on Sep. 18 from 12:00 to 12:30 pm PDT. The 2nd/Broadway station is a part of Regional Connector Transit Corridor (RCC) expansion project for Los Angeles Metro and required a cut and cover excavation of 500 ft long by 97 ft. deep, underneath 2nd Street. If you are interested in learning more about our design, challenges and lessons learned, register for the free webinar using the link below.

PB&A in Hawaii

PB&A, Inc, is working with Shimmick-Traylor-Granite in Honolulu to bring the new HART Light Rail to Oahu.  Our first trestle designed was built over the Halawa Creek to accommodate pier installation with heavy equipment including LB44 and HS895 crane.  She served her purpose successfully and is now on her way out.  Onward to Moana Lua!

Tunneling Machine Dropped into PB&A’s “Hole”!

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.
