THE CHALLENGE
The approach for the Metro Line Light Rail Transit (LRT) project came with several complexities to consider. Among these was the coordination of a 30-person night crew tasked with suspending sections of rail while a concrete slab was placed around anchor bolts attached to the rail, affixing the rail to the concrete. This required precise rail temperatures between 17 and 24 degrees Celsius (62 and 75 degrees Fahrenheit). To address this, project managers needed a solution to predict optimal scheduling windows by monitoring temperature trends in advance. Additionally, the project called for certain International Organization for Standardization (ISO) requirements which necessitated the development of a more robust quality control program.
THE SOLUTION
To tackle these complex challenges, the team adopted temperature sensors. Positioned strategically in the spring, these sensors collected data throughout the summer, aiding in planning and scheduling suspended concrete pours. By cross-referencing real-time sensor data with weather forecasts, the team scheduled pours six weeks in advance, with critical checks at three weeks. The temperature sensors were also integrated into the pouring process to guarantee the installation of rails within the specified temperature parameters.
THE RESULT
1. Cost Savings:
The ability to schedule concrete pours more accurately and minimize quality issues led to substantial cost savings. Reduced downtime, lower rework expenses, and optimized resource allocation contributed to a more cost-efficient project execution.
2.Improved Scheduling Precision:
The use of temperature sensors enabled project managers to predict optimal scheduling windows for concrete pouring with a high degree of accuracy.
3. Elevating Quality Assurance:
The seamless integration of temperature monitoring sensors has elevated quality assurance for the Metro Line LRT Project, ensuring the client received the highest level of project excellence. These enhancements set the stage for continued partnerships and future projects, solidifying a commitment to deliver top-tier results.
4. Risk Mitigation:
By proactively monitoring temperature trends and planning concrete pours accordingly, the project team effectively mitigated the risk of temperature-related issues, such as concrete curing problems or rail deformities. This risk reduction contributed to a smoother project execution and minimized the need for costly corrective actions.
