Compared to a residential LETI 2020 (Band C) target building (A-C) with a total embodied carbon of 675 kgCO2/m2, that is equivalent to just 0.7% reduction in carbon..
MMC can be considered as the DfMA designer’s “toolkit”.The DfMA designer finds the most suitable innovations in the MMC toolkit (or develops new innovations) to meet a project’s unique challenges..
There are many construction innovations that can be considered MMC.The UK’s Ministry for Housing, Communities and Local Government (MHCLG) recently established a Joint Industry Working Group on MMC which proposed the following categorisation: 3D primary structural systems, 2D primary structural systems, Non-system components, Additive Manufacturing, Assemblies and sub-assemblies, Material and Product Innovations and Site Process Innovations.This categorisation is quite diverse and includes a range of pre-manufactured and pre-assembled systems but also non-system components, site-based material innovations and process innovations..
There is no fixed list of MMC methods in each category.There is great scope for the construction industry to innovate and develop new MMC methods to expand the toolkit and enhance the DfMA designer’s ability to achieve benefits on future construction projects..
Under the MHCLG categorisation, volumetric modular construction (known in Singapore as Prefabricated Prefinished Volumetric Construction or PPVC and in Hong Kong as Modular Integrated Construction or MiC) is an example of a 3D primary structural system..
In addition to volumetric solutions, many other different MMC methods including flat-pack and componentised systems are primarily prefabricated and are often grouped under the umbrella term “Offsite”..Lessons from Other Sectors.
Jacqui discusses how construction can learn from more integrated sectors like aerospace and automotive, where industry voices are more unified and the government provides more substantial support, allowing for quicker advancements.. 5.Future of Construction.
The industry needs a shift in business models, moving away from return on capital employed to a focus on sustainability and innovation.Achieving net-zero carbon goals is critical, and future construction must be more digitally integrated and collaborative.When we talk about the sustainable design of buildings, we have two core objectives: reducing environmental impact, and providing a healthy space for occupants.
