UK construction, services and investment group Balfour Beatty said on Wednesday it has acquired Dean & Dyball, a regional civil engineering and building business, for £45 mln (EUR 57 mln). 'The acquisition of Dean & Dyball is the latest stage in our strategy of building leading positions in regional UK civil engineering and building markets following the successful acquisition and integration of Mansell, Birse and Cowlin', said Balfour Beatty Chief Executive, Ian Tyler. 'This transaction establishes a strong civil engineering base in an area where we currently have only a limited presence and adds further capability in the building sector.'
