Keltbray boosts construction efficiency at a 49-storey residential project by using the Converge Helix System's long-range capabilities to monitor concrete strength in real-time.
Keltbray is implementing advanced construction methods at the Western Yards, a 49-storey residential building in Central London. The project includes post-tensioned slabs and a self-climbing jump form system for the core walls.
The challenge, however, is ensuring the concrete reaches the required strength within a short time frame for both initial and full stressing.
By using the Helix Converge system, Keltbray can accurately measure concrete strength 10 - 15 hours after pouring. This allows for timely initial stressing of the PT slabs and striking of the jump form, maintaining the project's tight schedule.
With the Helix Converge system, Keltbray can quickly and accurately assess concrete strength. This capability ensures the project stays on schedule by allowing work to proceed promptly once the concrete reaches the required strength.
The long-range wireless technology of the Helix system allows for safe and secure placement of nodes. Keltbray used 4 nodes at the 49-storey Western Yards site. Even at a substantial distance from the pour location, Helix collects real-time data which is sent to the cloud-based dashboard. This flexibility ensures accurate results without compromising site safety or efficiency.
Receiving concrete strength results promptly enables labourers to resume work immediately, eliminating delays caused by waiting for lab test results. For instance, if a pour finishes at 5 PM on Day 1, having the strength results available by the start of Day 2 allows work to continue the next morning, provided the required strength is achieved. This efficiency removes the need to wait for test cube reports from the lab, significantly speeding up the construction process and reducing both downtime and labour costs. This contributes to substantial overall project savings.
