Prefab MEP Manufacturer Accreditation Scheme

It is jointly developed by BCA and STAS. STAS is the appointed administrator for the scheme and will award the Prefab MEP MAS Certificate of Accreditation. The accreditation assessment emphasises on the capabilities, processes, and specific quality criteria required for the production of prefab MEP modules. The scheme helps to ensure quality assurance and control in the design, production, and installation of prefab MEP modules. It also helps to validate the processes used by the prefab MEP manufacturers to produce high quality prefab MEP systems and maintains good quality standards.
