It's important that when we define chips, we don't leave gaps.
Build Efficiently: implement innovative construction strategies such as Modern methods of Construction (MMC) and use a DfMA approach to reduce waste onsite..Offset: Any remaining carbon should be offset via recognised carbon offset schemes.
Offsets used should be publicly disclosed.. An example of design strategies that follow the proposed embodied carbon hierarchy is shown in Figure 5..Step-by-step hierarchy for net zero embodied carbon.Design for Manufacture and Assembly (DfMA).
As identified above, DfMA is an essential part of the strategy to achieve net zero embodied and operational carbon.Bryden Wood’s Platform approach to Design for Manufacture and Assembly (P-DfMA) is a system that delivers efficiencies across the entire construction process by applying the principles of manufacturing.. Bryden Wood have taken the P-DfMA approach for the design of multiple projects, like Landsec’s The Forge office development in London, where we have followed the hierarchies described above..
The Forge.. Its lean design, using a standardised ’kit-of-parts’ and the better control on the specification and procurement of materials has shown the following benefits:.
Reduction of the amount of material used.The construction eco-system and the impact on value.
Still, the current industry obstacle isn’t really that we don’t agree on the importance of value, or think that working towards value isn’t a smart idea.. Amy Marks feels the blocker here is the same as it is for topics like prefabrication and productisation in construction - that the entire ecosystem is set up in a way that prevents those things from happening.. “I could determine value as speed,” she says, “but then every contract I have, every process I have, every decision-making point, all these procurement methodologies - they're not based on speed.So you could say you want speed, but unless you change the contract, the risk management profile, the processes - in order to achieve speed, instead of what you do every single day - you're not going to get speed.”.
It’s a fundamental issue and if we truly want to realise the potential industrialised construction has to offer, we need to address it.. “We rarely change the entropy of processes and behaviours around the good idea,” says Amy Marks.“That's why it doesn't happen, not because it's not a good idea.
