SAN FRANCISCO — The founders of a well-known Oakland construction company, the son of an Oakland councilman, a former state Veterans Affairs official and other Bay Area contractors have been indicted by the federal government in construction bid-rigging schemes.

Federal prosecutors said Friday that two founders of Turner Group Construction — CFO Len Turner and COO Lance Turner — and Oakland City Councilman Larry Reid’s son Taj Reid conspired to defraud the Department of Energy on a Lawrence Berkeley Lab renovation project in 2013. The Turner Group has worked on a number of high-profile construction projects in Oakland, including restoration of the historic Fox Theater, the Alameda County Family Justice Center, and a number of public school and BART projects.

Lance Turner, 57, of Oakland, and Len Turner, 56, of San Leandro, and Reid, 46, of Oakland, did not return calls for comment on Friday.

Prosecutors said the indictments arose out of the 2012-2014 public corruption investigation of then-state Sen. Leland Yee, San Francisco political consultant Keith Jackson, and San Francisco mob boss Raymond “Shrimp Boy” Chow, and involved the same “FBI source” who went undercover as a developer to obtain the most recent indictments. Jackson introduced the “developer” to three of the men indicted Thursday, according to prosecutors.

The U.S. attorney’s office also obtained an indictment against Pleasant Hill resident Eric Worthen, a former official with the California Department of Veterans Affairs, who is accused of working with Reid to take $12,000 worth of bribes from the undercover “developer.” It’s unclear if Reid was working under anyone’s employ during the alleged schemes.

Prosecutors say Worthen, 45, was working for the CalVet homes for the veterans division when he and Reid offered the undercover FBI employee the “inside advantage” on the construction of two CalVet projects, a veterans’ home in Ventura and a home remodel in West Los Angeles, by circumventing the normal bidding process.

“For both construction projects, the ‘developer’ to whom Worthen and Reid were providing an inside track on the CalVet contracts was, in actuality, a source working for the FBI. The source was posing as a developer willing to pay bribes in order to obtain contracts with public agencies,” the U.S. attorney’s office said in a news release.

Reid and the Turners are accused of offering to submit a high bid to a Lawrence Berkeley Lab modernization project in 2013 so that the “developer” could win the project.

Reid is charged with two counts of bribery and two counts of conspiracy; Worthen is charged with three bribery counts; and the Turners are each charged with one conspiracy count.

The Turner Group has longtime political ties in Oakland. Council members Desley Brooks and Larry Reid were accused by the city auditor in 2013 of illegally directing city staffers to award a $2 million demolition project at the Oakland Army Base to the company. Another developer won the project after the city administrator ordered a competitive bidding process.

Also indicted on Thursday were four other Bay Area contractors accused of conspiring to rig the bidding process for the Lawrence Berkeley Lab renovation in 2013. Derf Butler, 53, of Vallejo, president of Butler Enterprise Group, LLC in San Francisco, is charged with conspiracy and making a false statement. Anton Kalafati, 33, of San Francisco, president of San Francisco-based B Side, Inc., is charged with conspiracy and two counts of making false statements. Clifton Burch, 49, of San Lorenzo, president of Empire Engineering and Construction Inc, in Oakland and San Francisco, and Peter McKean, 48, of San Mateo, vice president of Townsend Management Inc. in San Francisco, are each charged with one conspiracy count.

All of the men are scheduled to be arraigned in federal court on April 17 and are not in custody. A conviction for conspiracy to defraud the federal government is punishable by up to five years in prison and a $250,000 fine. Receiving a bribe by an agent of an organization receiving federal funds is punishable by up to 10 years in prison and a $250,000 fine.
