To avoid shutting down a vital rail commuter line amid urban development, Monir Precision Monitoring was contracted to monitor displacement of the rail and shoring of the excavation during construction of a condominium. The strict monitoring guidelines for working within the corridor, moist ground conditions, and multilevel approvals required presented challenges, leading Monir to explore an integrated digital solution to overcome the limitations of previous monitoring solutions.  As a proof-of-concept project, Monir selected iTwin IoT to test incorporating a digital twin within their existing IoT monitoring processes to visualize and assess the site throughout the construction process. Using Bentley’s platform for management and visualization of the instrumentation data increased operational efficiencies by 40%. The software helped save approximately 3,000 hours in on-site assessments and reduced the project timeline by six months. Compared to a myopic view using individual sensors, the digital twin solution provided a more holistic visual monitoring context relative to the entire project
