PB&A, Inc. has come a long way, but our mission remains: to approach each client partnership with integrity, while responding to every challenge with efficiency and singular attentiveness.


PB&A continues to make significant contributions to the advancement of technical design and analysis of shoring and earth retention systems for the built environment. The firm is constantly striving to push the boundaries of the profession and bring new insight to a constantly evolving but highly specialized field.

Recently the firm published articles detailing the use of a permanent Soil Nail Wall design for the foundation of the new Stanley Hall at the University of California, Berkeley, and the Soil Nail shoring design for the 83 ft. excavation of the North Anchorage of the new Carquinez Bridge.


Now with a substantial portfolio of successfully completed projects, PB&A has become a recognized leader in the specialized field of geo-structures design.
The need to accommodate internal and external growth has the company on the move once again, this time to its current home at 124 Greenfield, Ave. in San Anselmo, CA.

In 2000 PB&A drafts new code for the use of Soil Nail, and Soldier Beam and Tie Back permanent earth retention systems for California Essential Facilities. The code language, developed for OSHPD is added to the California Building Code Title 24.


With a growing clientele and projects underway across the bay area, PB&A relocates to larger and more centrally located offices in Oakland, CA.
The company flourishes over the next 10 years, marketing to a greatly expanded client base, and taking on more complex projects throughout California, Utah, Arizona, Nevada and New Mexico.


Mr. Barar founds PB&A Inc. in San Francisco.
The practice serves as the catalyst for Mr. Barar to focus his years of diverse structural analysis and design experience into the specialization of Geo-Structures design.
During this period Mr. Barar engineers the first Soil Nailed Wall in the Western United States for a 30 ft. excavation at 1330 North California in Walnut Creek, California.


Prior to the inception of PB&A, Mr. Barar worked for the design firm of Skidmore, Owings & Merrill for more than 16 years.
During this time he refined his expertise on a variety of traditional vertical structural design projects. His true interest, however, was in the advancement and utilization of more efficient and effective earth retention systems for a greater variety of building and infrastructure projects.
