Despite being this concrete framer's first use of Converge, training was completed in 3 hours - including the time taken to deploy the first set of sensors. Cycle times reduced from the first level and continued to improve throughout the program. By Level 10, the program was ahead of schedule.
As shown in the chart on the right, in-situ strength monitoring highlighted the variability in concrete performance throughout the year. Between colder months and warmer months, there was up to 700% variability in the time it took to reach key strengths. Conventional techniques for determining concrete strengths (ie. cubes cured at 20°C) indicate the same performance all-year-round, leading to unnecessary delays in Summer, and potentially dangerous situations in Winter. Converge’s technology gives accurate strength estimates at all times of year, improving safety and efficiency on-site.
The cost of sensors and hire of equipment/software for this type of project is around £35k. Had this project continued as it began, delivery would have been 10 weeks late - a delay which can often translate into LAD’s and prelim costs of £1-2m. That said, the ability to win new client business may prove more valuable still.
“South Lambeth Road went from a 7-day cycle per floor to 5-days, based solely on Converge. The client not only dropped penalties for late delivery - they asked us to tender for another project!" --- Louise Flaherty, Design Manager
