Pirooz Barar, S.E. Principal Engineer
Pirooz Barar has over 40 years of structural engineering analysis and design experience, with the last 30 years devoted to the development of advanced technical methodology for the design of shoring, underpinning and earth retention. Mr. Barar has extensive experience providing innovative engineering solutions, including soil nailing, Soldier Beams and Tiebacks, internal bracing, micropiles, and deep shafts for a variety of development projects and transportation geo-structures. Mr. Barar authored a report to Congress, funded by the National Science Foundation on the behavior of Permanent Soil Nailed Walls in California following the Loma Prieta earthquake of 1989, and served as the chairman of the Soil Nail Committee, formed with the City of Los Angeles, to establish and publish guidelines for the design, construction, and inspection of permanent Soil Nailed Walls in the City and County of Los Angeles. During the past several years Pirooz Barar has written Design Criteria for design, inspection and construction of Soil Nail and Tie-back installations used in projects where a hospital was in full operation during construction of new additions falling under the jurisdiction of OSHPD. Much of Mr. Barar’s criteria have been entered into the OSHPD code for the design and construction of hospitals in the State of California. Notable Projects
