Aecom has been named the world’s biggest architectural firm as part of the annual WA100 survey by Building Design. The survey ranks the world’s largest practices by the number of fee-earning architects they employ.

With a large presence in the Middle East, Aecom has worked on projects such as the Siemens Headquarters in Masdar City (pictured).

The firm is also behind the masterplan for the Rio 2016 Olympics and now employs 2,100 architects, a quarter more than second-placed firm, Japanese practice Nikken Sekkei.

Gensler, another US-based firm, slipped to third from first in the previous year. It currently employs 1,614 architects, the survey found.

The number of architects employed by the WA Top 100 practices grew by more than 15%, with Aecom becoming the first company with more than 2,100 architects.
