The 14-storey building will be the new UK headquarters of Swiss bank UBS.
Mace has been appointed under a construction management agreement following 12 months delivering extensive utility diversions, enabling works and pre-construction advice to British Land and Blackstone.
As well as being the next stage in the development of Broadgate, 5 Broadgate is designed to be the 'greenest' building in the Square Mile. The project, which is on track for a BREEAM 'excellent' rating, will incorporate high sustainability standards and environmental features in terms of its energy performance. It is claimed that it will have more solar photovoltaic panels than any other commercial building in London.
Mace chief operating officer for construction Gareth Lewis said: "Following our successful delivery of Ropemaker Place for British Land, we welcome the challenge of working with them to deliver another iconic building that sets new standards in green design and construction."
Other members of the design team include Make as architects, Watkins Payne as building services engineer, Buro Happold as structural engineers, M3 as project manager and Sense, the cost consultancy arm of the Mace.
