Latham & Watkins, Fried Frank, and Wachtell Lipton Rosen & Katz have taken lead roles on Jacobs Engineering's $3.27bn (£2.47bn) acquisition of global engineering rival CH2M.

CH2M, which is based in Colorado, has about 2,500 staff in the UK, of a total of 20,000 around the world. It has won a number of high profile UK contracts in recent years, including work on HS2 and refurbishing the Palace of Westminster.
