DFMA Guide to Timber Panelised MMC
DFMA (Design for Manufacture and Assembly) is an important consideration for optimising and maximising the use of panelised MMC systems. DFMA is an industrialised approach common in many manufacturing environments.
Early in the design life cycle, housing designs can be optimised to make best use of panelised MMC, leading to lower costs and improved quality while increasing surety of construction execution.
This guide provides information and knowledge on critical areas of design, that maximise manufacturing and construction of timber panelised MMC systems and remove complexities.
This work package was delivered by the AIMCH MMC manufacturing partner Stewart Milne Group. The DFMA guide is targeted at designers and specifiers of homes.
The guide covers six core areas of design consideration:
- Design sequence – key decisions
- Design constraints – limiting factors
- Structural principles – walls, floors and roofs
- Differential movement – cladding interfaces
- Building services – plumbing and electrical interfaces
- Windows & doors – openings and setting out
The DFMA Guide acts as a useful prompt to design out or recognise where design decisions will impact construction.
The DFMA Guide, thought to be one of the first its kind, will be used in the development of AIMCH industrialised affordable housing designs, using panelised timber offsite MMC technologies.
DFMA in conjunction with design standardisation and 3D building information modelling can be very powerful tools. They have the potential to transform housing design and delivery, fuelling the creation of more homes at lower cost.
AIMCH has delivered a result that is often discussed but difficult to tangibly realise. The DFMA Guide for offsite panelised timber MMC systems provides a model example and supports a step change in attitude towards industrialised thinking and housing design practices.
The DFMA Guide provides a framework for housing designers to utilise in the creation of DFMA-friendly industrialised housing designs of the future.
The DFMA Guide, thought to be one of the first its kind, will be used in the development of AIMCH Industrialised Affordable Housing Designs, embracing design standardisation, product families and 3D BIM modelling derived within the AIMCH project.
DFMA, design standardisation and 3D BIM are very powerful tools to transform housing design and delivery, leveraging learnings from the automotive sector, where these approaches have excelled.
AIMCH ambition is to create a path to delivering more industrialised homes at an affordable cost through the creation and exploitation of future industrialised housing designs.
