The construction industry has languished in terms of productivity growth for decades. But there are ideas, some of which are mentioned in this white paper from UK firm Balfour Beatty. Many are organized around the idea of prefabricating as many components as possible offset, then bringing them in for assembly. Another way of looking at it is that construction is basically a form of (inefficient, risky and very site-specific) manufacturing, and can try to learn some lessons from other manufacturing industries.
…we know this is an industry that lives on thin margins, is plagued by time and cost overruns and inherently operates in one of the higher risk environments of any sector – risk in terms of cost, time and, above all, human safety. But do we also think of this as an industry with one of the largest opportunities of any sector to transform its model? Can we think of many industries where the size of the prize is to shift 25% of current output to a solution that radically improves speed, quality and safety – all while creating (not destroying) jobs?
Today a new generation of industrialised construction methods, including offsite and modular building techniques, are increasingly being recognised as the best way for the UK construction industry to boost productivity and plug skills shortages. And moving to these methods drives better outcomes for all stakeholders: for the customer, reducing onsite construction times and waste; for the construction supply chain, by improving quality, repeatability (and
therefore output) of infrastructure; for the workforce above all, by raising safety performance and securing long-term employment.
