Editorial: Special Issue on Developments in Construction 4.0

Built environment has been perennially caught up in low productivity conundrum for a long time. This is despite its significant impact on industrial employment (i.e. over 6.6% contribution) and representation of 9.8% of the UK’s Gross Domestic Product (Rhodes, 2019). Poor collaborative processes through effective information exchanges has been identified as a major reason for this (Crotty, 2013; Kumar, 2015). Besides, the knowledge gap between design and construction has also been cited as a major contributor to this discontinuity (Abrishami et al., 2014; Fruchter et al., 2016; Goulding and Pour Rahimian, 2019; Goulding et al., 2015; Pour Rahimian et al., 2019; Pour Rahimian et al., 2008; Pour Rahimian et al., 2011).
