Boston-based Suffolk Construction Co. acquired ROEL Construction of San Diego and Irvine for an undisclosed price. Suffolk ranked No. 31 on ENR’s Top 400 list with $1.7 billion in 2009 revenue. ROEL was No. 329 on the list with $168 million in revenue. ROEL CEO Wayne Hickey will be the CEO of the new entity, according to spokeswoman Carolyn Spicer, who says Suffolk plans to engage in some market research to determine whether the company will operate under the name ROEL. ROEL is a 90-year-old, family-owned firm. Suffolk has an Irvine office; Spicer says it has not been determined if the offices will combine.
