Fluor did not name a COO successor, stating that Chairman and CEO David T. Seaton, 55, would take the additional role. Fluor also said that Chief Financial Officer Biggs Porter, 64, will retire by year-end, when his successor is named. He joined the firm in 2012.

Fluor was named in February as one of Fortune magazine’s most admired corporations, ranking highest among engineering and construction firms for the sixth year in a row, the company noted. The list is based on a tally of queries to thousands of executives, board directors and analysts and measures corporate reputation and performance against nine criteria.

While the projects “remain challenged,” he said, Fluor’s cost-reimbursable contract is “insulating it from further cost escalation.”
