Hatch Mott MacDonald CEO Nick DeNichilo and Executive Vice President Michael Schatz are set to take on new executive roles at U.K.-based Mott MacDonald Group Ltd. and Canada-based Hatch Group, respectively, after the parent firms’ infrastructure-engineering joint venture splits in early 2016.

Nick DeNichilo

Iselin, N.J.-based HMM’s Canada business will become part of Hatch, while its U.S. operation, along with its North American pipeline engineering work, will join Mott MacDonald. Schatz is named managing director of infrastructure at Hatch, and DeNichilo will become president and CEO of Mott MacDonald in North America.

Michael Schatz

The JV, formed about 20 years ago, has about 3,000 employees and reported 2014 revenue of $473.4 million—half in transportation, 27% in industrial and $171.8 million in Canada. The firm ranks at No. 36 on ENR’s list of the Top 500 Design Firms. Although both units will continue to work across North America, DeNichilo says they “agree that the route to achieving their growth ambitions” is to operate as separate companies. 

Eric Stenman

Eric Stenman has been named to the added role of chief operating officer of Balfour Beatty Construction U.S. He is CEO of the contractor's San Diego-based west region covering operations in California, Arizona, Washington, and Oregon, and head of its national mission critical business unit. Stenman is formerly president of contractor Douglas E. Barnhart Inc., which was acquired by Heery International in 2008, and by Balfour Beatty Construction in 2010. Stenman is a director of the Associated General Contractors of America in San Diego and national vice chair of its building division. In his new role, he succeeds John Tarpey who has been elevated to chief of organization development at the firm.

Professional services firm Kleinfelder, San Diego, has named as interim president and CEO Kevin Pottmeyer, who had been senior vice president and chief strategy officer. He replaces William C. “Bill” Siegel, who the company says “has resigned to pursue other interests.” Kleinfelder directors said they will conduct a search for a new CEO. Siegel had been with Kleinfelder since 1989 and CEO since 2009. The firm ranks at No. 39 on ENR’s Top 500 Design Firms list and at No. 44 on the Top 200 Environmental Firms list.
