Automated Real-Time Monitoring System to Measure Shift Production of Tunnel Construction Projects

AbstractThe productivity of a tunnel construction project can deviate from the predicted plan due to many factors, such as equipment failure, weather conditions and unexpected soil characteristics. Early detection of such deviations can help management teams to reallocate resources and take necessary actions to maximize the productivity. The real-time monitoring of actual productivity would yield tremendous information toward this end, but such monitoring is difficult, especially with remote construction sites. Therefore, the common practice has been to periodically obtain manually generated aggregated productivity reports from sites. These aggregated reports are not available to both site and office management in real time and may lack detailed information. To avoid these drawbacks, the research presented in this paper proposes an automated tunnel construction monitoring system to measure the productivity of the tunnel construction in terms of shift production (meters/shift). This system computes the shi...
