Why CPM Falls Short in Linear Construction Projects
The Critical path method (CPM) is widely used but often falls short for scheduling linear tasks in projects like road construction, tunnels, pipelines, and high-rise buildings, where activities repeat at various sections. CPM struggles with arbitrarily dividing these repetitive tasks and maintaining resource continuity. It also requires many activities to depict linear projects, fails to show progress rates, and doesn't accurately reflect real-time project conditions or indicate where work is currently taking place on site. This makes CPM less effective for managing linear construction projects.
