This article “Building Information Modelling, Artificial Intelligence and Construction Tech” was written by Rafael Sacks, PhD, Mark Girolami, PhD, Ioannis Brilakis, PhD in 2020 and published in “Developments in the Built Environment” magazine on October 4, 2020. In this article it is reported that an adoption of digital information tools in the construction sector provides fertile ground for the birth and growth of companies that specialize in applications of technologies to design and construction. While some of the technologies are new, many implement ideas proposed in construction research decades ago that were impractical without a sound digital building information foundation. Yet only within the past five years has venture capital actively sought startup companies in the ‘Construction Tech' sector. Following a set of digital construction innovations through their known past and their uncertain present, the authors review their increasingly optimistic future, all through the lens of their dependence on digital information. The review identifies new challenges, yielding a set of research topics with the potential to unlock a range of future applications that apply artificial intelligence.
