State high-speed rail officials acknowledged Thursday that they changed their rules for selecting a builder for the bullet train's first phase in the Central Valley, a shift that subsequently made it possible for a consortium led by Sylmar-based Tutor Perini to be ranked as the top candidate despite receiving the lowest technical rating.
The California High-Speed Rail Authority announced last week that the Tutor Perini-Zachry-Parsons joint venture was the top-rated contender among five bidders seeking to build the initial 29 miles of track between Madera and Fresno.
While it offered the lowest price at $985.1 million, the Tutor Perini team's technical score ranked last. Ferrovial and Acciona, two Spanish firms with significant high-speed rail experience, had the highest technical mark but bid almost $1.4 billion. The rail agency board is expected to select a contractor in the coming months after additional negotiations.
