John DiCiurcio, who had been, since 2011, the Chicago-based chief operating officer of building contractor Turner Construction Co., New York City, has been elevated to CEO of Flatiron Construction, the Longmont, Colo., infrastructure builder.

Previously named as Flatiron's COO in December and a member of its executive board since 2007, he now replaces Tom Rademacher, who has left the company, a Flatiron spokeswoman confirms.


Both Flatiron and Turner are subsidiaries of Germany-based construction firm Hochtief. Flatiron was acquired in 2007.

The spokeswoman did not disclose Rademacher's new employer, and the former CEO could not be reached. But according to sources close to the company who are not authorized to speak publicly, he is currently recuperating from injuries sustained in a serious vehicle crash last month.

Spanish contractor ACS, which also owns Spain-based contractor Dragados S.A., gained majority control of Hochtief in 2011 in a hostile takeover. Marcelino Fernández Verdes, a former ACS executive, was named Hochtief CEO in November 2012. He had previously led its Americas division. Rademacher, who was Flatiron CEO since 2007, joined the firm in the early 1990s.


Bradley L. Mallory, former president and CEO of engineer Michael Baker Corp., Moon Township, Pa., will join the Pennsylvania Dept. of Transportation this month as deputy secretary of administration, a change confirmed to ENR on Feb. 4 by agency spokeswoman Erin Waters-Trassatt.

Mallory, who resigned from the firm in December at the request of its board, had been in those roles since 2008. He could not be reached for comment.

Before joining Baker, Mallory was the transportation secretary in Pennsylvania. He also is a past president of the American Association of State Highway and Transportation Officials.

Waters-Trassatt says Mallory replaces Mark Compton, who was named CEO of the Pennsylvania Turnpike Commission in December.

Baker also announced that Richard L. Shaw has retired as chairman. Shaw, 85, who served as Baker CEO four times during his company tenure, had been chairman since 1991 and joined the firm in 1952 as assistant personnel director. Succeeding him is Robert N. Bontempo, a Columbia University business school professor and board member since 1997.

Baker also said last month it has hired executive search firm Korn/Ferry International to help it find a new CEO, a search that the firm says will include both internal and outside candidates.

Diane O'Keefe has been named vice president and Illinois area manager for Parsons Brinckerhoff, New York City. Based in Chicago, she joins the firm after a 30-year career at the Illinois Dept. of Transportation, most recently as deputy director of highways in a six-county region. She also had been the region's bureau chief of design and program development director.
