Optimizing High-Rise Construction Timelines Using CPM Scheduling: A Case Study by HSE Contractors

This technical note presents a case study conducted by HSE Contractors on the application of Critical Path Method (CPM) scheduling to optimize project delivery timelines for a 26-story residential tower in New York City. The report outlines key strategies in baseline schedule development, delay analysis, and time impact studies (TIA) used to address complex logistical, weather-related, and sequencing challenges. Through the integration of professional scheduling practices and forensic analysis, the study demonstrates how accurate CPM modeling and delay mitigation can reduce project risk, support claims preparation, and drive on-time completion. The case serves as a reference for construction managers, schedulers, and developers aiming to implement CPM-based risk management in high-rise urban construction projects.
