Scheduling of highway construction in Primavera involves breaking down the project into detailed activities such as site preparation, earthwork, drainage, pavement, bridges, and finishing works. Each activity will be assigned duration, dependencies, and resources to ensure proper sequencing for efficiency in the performance of work. Critical Path Method (CPM) is used to identify the key tasks that have an impact on project completion. With Primavera, one can monitor progress against the planned schedule, detect delays, and optimize schedules through resource leveling and risk analysis. Regular updates and adjustments help keep the project on track, ensuring timely and cost-effective completion.
