Gensler clinched the number one spot for the fifth consecutive year in this year’s edition of the annual Top 300 Architecture Firms list, which is out now from Architectural Record. The list ranks U.S. companies based on revenue for architectural services performed in 2015, breaking out total architecture revenue, how much of that was domestic and international, percent of design revenue from architecture, and total design revenue in millions of dollars.
Gensler, which is based in San Francisco and is responsible for buildings including the Shanghai Tower, Incheon International Airport in South Korea, Airbnb’s San Francisco office, as well as the world’s first 3D-printed office, was the first firm to surpass $1 billion in revenue in 2014. Last year, Gensler increased that total revenue by over $100 million, bringing in a sky-high $1,181,030,000.
Los Angeles-based AECOM remained in the number two spot after seeing a 30% increase in revenue, largely due to AECOM’s recent $6 billion acquisition of the engineering and design firm URS Corporation. This move made AECOM, known for its design of the Abu Dhabi International Airport and the Golden 1 Center stadium in Sacramento, the largest publicly traded company in the Los Angeles area.
Chicago-based Perkins + Will and Jacobs in Pasadena traded spots for the third and fourth positions, respectively, while ARCADIS/Callison RTKL in Highlands Ranch, Colorado took the fifth spot.
