Pre-manufacturing components (non-systemised primary structure)
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 3 – Pre-manufacturing components (non-systemised primary structure) is defined as:
‘Use of pre-manufactured structural members made of framed or mass engineered timber, cold rolled or hot rolled steel or pre-cast concrete. Members to include load bearing beams, columns, walls, core structures and slabs that are not substantially in-situ workface constructed and are not part of a systemised design.
‘This category although focussed on superstructure elements, would also include sub-structure elements such as pre-fabricated ring beams, pile caps, driven piles and screw piles.’
