This is no simple task.
Lean construction in practice: a virtuous circle of benefits.All of these factors combine to deliver cost and material savings, while using fewer people and increasing productivity.
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.Spans can be specific to particular clients, but to the operative on site, it's the same yellow bracket, requiring the same torque wrench and two bolts.
Platforms enable us to get down to a much more granular level and simultaneously open the door for continual improvement and variability going forward with respect to supply chain choices, material choices and so on.. Maximising value with construction platforms.Because platform construction uses a limited number of components, it gives us a greater amount of control.
We’re able to limit the number of processes and operations which have to happen on site and we can control materials much more accurately.There are also considerable time-saving benefits with P-DfMA, which enable us to spend more time on the design and optimisation of components in the first place.
