International project management, engineering and consultancy business, Artelia, has expanded into the East of England to power a new phase in its UK project consultancy based around global capabilities in new energies, infrastructure and the built environment. Already working in the region on projects such as the restoration of Norwich Castle, Artelia has acquired leading Suffolk-based surveying practice, Castons Consulting Limited and its sister company CCAS Ltd, which specialise in cost management, building surveying, construction health & safety and principal designer services across the public and private sectors. The acquisition will take Artelia’s UK consultant team to over 200 people.

Established in 1895 and headquartered in Ipswich, Castons, has delivered projects across the East of England and enjoys a notable reputation as the go-to consultant of choice for cost and surveying solutions. The team also includes specialists in healthcare and RAAC panel surveying, closely aligning with Artelia UK’s NHS consultancy work. Through the acquisition of CCAS Ltd, Artelia will deepen its existing construction safety and Principal Designer service offering to clients as the new regulatory framework under the Building Safety Act takes effect.
