Toilets nested..

This iterative process can be shortened using BIM integration and digital twins which are inherently part of a DfMA approach..Increased skill/knowledge/preparation:.

Our experience has shown that the automation and design of P-DfMA processes simplifies the construction and the need for a skilled taskforce and their preparation.It also reduces the number of people onsite, increases safety as a result of reduced work at height, lowers capital costs and improves construction speed.. Passivhaus and net zero carbon challenges.There is an increasing amount of pressure growing in the construction industry to design net zero carbon buildings, both in terms of operational and embodied carbon.

In this context, bodies such as the London Energy Transformation Initiative (LETI), RIBA, GLA and UKGBC, have developed guidance documents on embodied carbon, which include specific targets and roadmaps to achieving net zero carbon prior to 2050.. Based on LETI Climate Emergency Design Guide, a typical medium size residential building embodied carbon, would be 33% of the total carbon, whilst the operational carbon would be around 67%.However, for an ultra-low energy building, like Passivhaus, the breakdown would be 77% embodied and 23% operational and this balance is likely to become more enhanced with the decarbonisation of the grid.

This means that embodied carbon is becoming a more important focus for the sustainable design of buildings..

Typical operational and embodied carbon breakdown for medium scale residential for a standard building (left) and for an ultra-low energy building.Only by dispelling the mystique of construction, can we reveal real value..

The construction industry needs to shift its thinking towards recognising similarity and repeatability by using repeatable components to create unique systems.. Construction companies are already operating at 100% capacity or more.Businesses aren’t competing for work, they’re trying to figure out ways to deliver all the work they already have, and how to deliver it with existing supply chain capacity and widespread skills shortage..

This reality creates an openness to new approaches and will force change, but we need interoperability of data, collaboration, and repeatability to make it happen.. Our need to build will only increase as the global population continues to grow, and the amount of energy and technology infrastructure required expands as we head into the future.The best incentive for industry-level change will come from owners, who are starting to understand the enormous financial costs of delays and disrupted schedules more than ever before.
