Stockholm-based design firm Sweco has elevated Åsa Bergman to president and CEO, effective April 20. She succeeds Tomas Carlsson, who is leaving two months earlier than planned to become CEO on May 7 of one of Sweden’s largest contractors, NCC AB. A 27-year firm veteran, Bergman has been CEO of its operations in Sweden since 2012. During her tenure, that unit has grown to 5,700 employees from about 3,000, the firm says. Women now hold 35% of its management positions, Bergman adds. With more than 14,500 global staff and nearly $1.2 billion in reported 2016 revenue, Sweco ranks No. 15 on ENR’s latest Top 225 International Design Firms list.

Alfred B. “Fred” Craig has been named CEO  of Purple Line Transit Partners, the public-private design-build partnership (P3) for the $5.6-billion, 16-mile Purple Line light rail in the Maryland suburbs of Washington, D.C. The venture, said to be the largest U.S. P3 project, is a link between the Maryland Dept. of Transportation and a consortium of Meridiam Services LLC, Fluor Corp. and Star America. Craig, a former Meridiam project manager, said in media reports that, as the former pursuit director for transit operator Transdev North America, he was an unsuccessful Purple Line bidder. Craig succeeds Rob Chappell, who left the role for personal reasons. Line construction began last fall, following a year of delay due to a lawsuit over ridership. It was dismissed in December. The line, to include 21 new stations, is set to open in 2022.

Anne Marie White took over March 29 as assistant secretary of energy for environmental management to now run the U.S. Energy Dept. unit that manages nuclear waste site cleanup. Her U.S. Senate confirmation on March 22 was held up by Sen. John Barrasso (R-Wyo), who opposed uranium barter by DOE. Energy Secretary Rick Perry suspended the program for the 2018 fiscal year. White, a nuclear engineer, is the founder of Bastet Technical Services LLC, which a DOE statement says is an agency consulting firm. She also was decommissioning lead at design firm Atkins, managing planning for the takedown of the Diablo Canyon nuclear power plant in California, says her Linked-In profile. White’s DOE unit has a $6.5-billion budget for fiscal 2018. Congress has approved $7.1 billion for fiscal 2019.

Nelson Ogunshakin will succeed Enrico Vink as managing director of the Geneva-based International Federation of Consulting Engineers (FIDIC).

Vink is retiring after 12 years in the post, having previously led New Zealand’s equivalent of ACE.
