SES Engineering Services, part of the Wates Group, has picked up two substantial M&E packages in central London together worth more than £30m.SES has been appointed to deliver mechanical, electrical and plumbing (MEP) services on Argent’s 12-storey S2 office building for Google, which is part of the King’s Cross regeneration. It has also secured an £18.6m MEP contract on Barts Square Phase One, a £110m residential development by Helical next to St Bart’s Hospital in Farringdon. Carillion is the main contractor for both projects.With logistics a key consideration in city centres, especially London, offsite construction is playing a key role in both projects.SES was previously Shepherd Engineering Services until its acquisition by Wates in 2015. Wates said that the two contract awards represented a major milestone for SES’ London and southeast operation. It attributed the King’s Cross win to SES’ digital engineering expertise, responding to the client’s requirement for building information modelling (BIM).With a 38 week programme set to complete in December 2017, SES will use its off-site manufacturing facility SES Prism to deliver 22 risers and a CHW roof plantroom.Off-site manufacturing techniques at SES Prism will also be used on the Barts Square project to design and install service cupboards for each apartment.These installations include a KNX power distribution system to allow residents to remotely control technology throughout the apartment, a heat interface unit, a heat recovery unit, cooling interface unit, underfloor heating manifolds, BT Home Hub and space for a washing machine. These units will be built off-site, in the SES Prism factory.
