Quoted consultant White Young Green has acquired Nolan Ryan Partnership, a 70-strong Irish QS and project manager, for £9.7m.

Nolan Ryan, which has been in business for 20 years, has a mix of public and private sector clients throughout Ireland.

Nolan Ryan will continue to trade under the same name but will form part of WYG’s enlarged management services business, which has a combined staff of more than 300 people.

John Ryan, managing partner of Nolan Ryan, will become joint managing director of WYG Ireland’s management services business.

John Purvis, chief executive of WYG, said the acquisition would bring a strong order book.

WYG acquired QS Tweeds for £11m earlier this year.
