Data from the sensors showed the concrete could reach the required strength 20 hours earlier than using the cube method, in theory reducing the five-day cycle for each floor to around four days.
Construction sensor and monitoring specialist Converge has said that it is working on a concrete thermal integrity system for the piling industry through collaboration with Keltbray Piling.
Both judges and delegates at the event felt that of the four start-ups that took part in the competition, Converge would have the biggest impact on the property industry.
After initial trials with a major contractor in 2015 the system has been deployed on projects including Hinkley Point C, the £1.7bn Royal Albert Docks development, 22 Bishopsgate and several Underground maintenance projects for Transport for London.
A technology start-up run by two Cambridge physics graduates is working with a major UK-based international contractor to develop a method of testing concrete strength using “Internet of Things” sensors and processing.
