Pre-manufacturing (non structural assemblies and sub-assemblies)
Modern Methods of Construction, Introducing the MMC definition framework, published by Ministry of Housing, Communities & Local Government (MHCLG) in 2019 defines 7 categories for MMC:
- Category 1 – Pre-manufacturing (3D primary structural systems).
- Category 2 – Pre-manufacturing (2D primary structural systems).
- Category 3 – Pre-manufacturing components (non-systemised primary structure).
- Category 4 – Additive manufacturing (structural and non-structural)
- Category 5 – Pre-manufacturing (non structural assemblies and sub-assemblies).
- Category 6 – Traditional building product led site labour reduction / productivity improvements.
- Category 7 – Site process led site labour reduction / productivity / assurance improvements.
Category 5 – Pre-manufacturing (non structural assemblies and sub-assemblies) is defined as:
‘A series of different pre-manufacturing approaches that includes unitised non-structural walling systems, roofing finish cassettes or assemblies (where not part of a wider structural building system), non-load bearing mini-volumetric units (sometimes referred to as ‘pods’) used for the highly serviced and more repeatable areas such as kitchens and bathrooms, utility cupboards, risers, plant rooms as well as pre-formed wiring looms, mechanical engineering composites would fall into this category.
‘Conventional masonry site constructed schemes utilising conventional building products such as windows and or door-sets – which might otherwise be part of the fabrication process in the other pre-manufacturing categories – should not be included as sub-assemblies or components in this category unless there is a further level of consolidation from traditional configurations. Also excludes and structural base elements that composite assemblies are fixed to and which are to be included in Cats 1-4. Any structure in this category is purely to support the sub-assembly in transit / install phase.’
