Gensler held first place for the fifth consecutive year in RECORD’s annual Top 300 Architecture Firms list. The list ranks companies based on their earnings in the previous year. Gensler, which surpassed $1 billion in revenue in 2014, increased revenue by more than $100 million in 2015. In response to the news, Gensler’s co-CEOs Andy Cohen and Diane Hoskins expressed a commitment to maintaining a seamless practice across the firm’s 46 international offices, and attributed the company’s success to its “talented global network of employees—Gensler’s constellation of stars.”

Los Angeles–based AECOM Technologies, taking the No. 2 spot on the list for the second year in a row, saw its revenue increase by more than 30 percent, jumping from $605 million in 2014 to $801 million in 2015. Executive Vice President Rebecca Nolan explained that this jump is largely due to AECOM’s recent $6 billion acquisition of the engineering and design firm URS Corporation, a move that made AECOM the largest publicly traded company in the Los Angeles area. Nolan also highlighted the Golden 1 Center stadium in Sacramento as a standout project from the past year.
