Federal authorities charged three former executives at a San Francisco design and engineering firm in cases involving alleged bribes to two city engineers and a building inspector. The scheme began at least as early as August 2003 and continued until February 2021, prosecutors say.

Siavash “Sia” Tahbazof, a developer and the former head of San Francisco-based SIA Consulting, along with SIA co-owner Reza Koshnevisan and Bahman Ghassemzadeh, who is Tahbazof’s nephew and worked as a civil engineer at the firm, are each facing one count of conspiracy to commit honest services wire fraud, the U.S. Dept. of Justice announced Nov. 13.
