Result

Increased construction speed and reduced labour down time

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.

Boosting Construction Efficiency at Western Yards

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.

The Solution

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.

Key Benefits

Accurate and Timely Concrete Strength Measurement

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.

Improved Site Safety and Efficiency

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.

Cost Savings and Reduced Labour Downtime

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.

The Helix Converge system has been essential in speeding up our work progress. We can get concrete strength results within 10-15 hours, enabling us to keep up with the cycle and save time and money.
