The move will strengthen Buro Happold’s depth of expertise in acoustics and AV technology.

Specifically, the acquisition will enhance standalone and combined services of acoustics and sound engineering, environmental advisory services, plus a broad range of electro-acoustic and technology offerings.

It also provides Buro Happold with a fully integrated mobility consulting capability, encompassing inclusive design, waste and logistics, and crowd and traffic consulting.

The two companies have worked together on a number of projects over the past two decades, including the new 62,850-capacity Tottenham Hotspur Stadium in London, UK, the Silverstone Racetrack, Qatar Education City Stadium and The Fisht Olympic Stadium in Sochi, Russia.

James Bruce, Buro Happold's CEO, said: "Having worked alongside Vanguardia and Crowd Dynamics International for more than 20 years, it’s a natural step to formally bring them into the wider Buro Happold portfolio.
