you can see that scale has little relative influence over the NPV at different scales.
We’re already seeing evidence that it’s possible to build a superstructure with half the number of people in half the time, representing a four-fold increase in productivity, as well as a 25% reduction in overall material and a 20% reduction in embodied carbon.And there are other benefits, such as the ability to minimise tolerances.
In our work with Crossrail we designed to zero tolerance with very good success.This unlocks vast potential in terms of manufacturing a better quality of building - structures which are more air- and weather-tight, energy efficient and overall better performing.Further, standardisation allows us to do a better job of integrating our mechanical and electrical engineering systems, which then has the knock-on effect of reducing the overall volume of a building by 30-40%.
As the building gets smaller, so does the air handling plant.This creates a reduction in running costs - heating and lighting.
In other words, we create a virtuous circle of benefit.. What is the future of the construction industry?.
Ultimately, we suspect that over time buildings will become flexible configurations of components, rather than large, fixed assets.Tier 1 and the supply chain.
Another benefit we see from DfMA construction is the evolution of a more direct relationship between the customer and their supply chain partners, cutting down on transactional costs and eliminating a lot of inefficiency.The contractor’s role becomes more profitable and sophisticated – what we refer to as a manufacturing assembly manager.
We believe that going forward this role will put more effort into controlling logistics, supply chain etc… In fact, roles throughout the supply chain will change, becoming more efficient and more focused on driving value.. Meeting the needs of our clients.Over the years, we’ve come to recognise a wide variety of client drivers, including cost, time, net present value, capital and funding decisions.
