Cheshire-based environmental consultancy RSK Group has started 2008 in the same acquisitive mood as last year with the takeover of testing specialist Building Sciences.
Building Sciences' clients include British Land, Asda, HBG Construction and Bovis Lend Lease.
Dr Alan Ryder, chairman and founder of RSK, said: "This is a fantastic addition to the RSK group; legislation and consumers are demanding greater efficiency in terms of building design and RSK and Building Sciences want to be at the forefront of making that a reality."
RSK is based in Helsby and has 750 staff across 34 offices worldwide. Last year it acquired six companies and increased turnover by 50%. More deals are expected this year.
