Bringing our capabilities together

BES strengthens our controlled environments offering within M Group’s Technical Services. Its ability to bring architecture, engineering and construction together supports clients from their earliest project decisions through to commissioning and validation. BES also brings complementary cleanroom modular systems expertise through Norwood, which it acquired in 2017, connecting specialist facility design with control over a key part of the supply chain.

What this means for clients and partners

Clients can access coordinated support throughout the project lifecycle, whether they need a full turnkey solution or expertise at a particular stage. Early engagement helps establish requirements, assess feasibility and develop realistic costs and schedules. Digital design and Building Information Modelling (BIM) support coordination across disciplines, while integrated construction and validation planning help bring facilities into use efficiently. This approach supports both new facilities and carefully planned work within operational environments.
