BAM uses artificial intelligence to predict concrete strength News Construction Manager Magazine

BAM Nuttall has used the world's first artificial intelligence (AI) concrete strength prediction engine on its £480m project to expand London City Airport. The system, developed in conjunction with concrete monitoring specialist Converge, takes advantage of Converge's concrete performance data set. Within hours of concrete being poured, Converge claimed it can predict the time a critical strength will be reached with an accuracy of /- 5%, several days in advance, by applying machine learning techniques. The predictions engine combines local weather data, a database of historical concrete curing data, and the Converge concrete monitoring platform's real-time measurements from the pour. Converge and BAM said the system led to improved productivity and can help keeps projects on track, ultimately saving millions of pounds if concrete sits in the critical path.
