Therefore, shop capacity is critical in maintaining a steady flow of work for all resources. By contrast, a job shop scheduling focuses on the continuous flow of work or jobs, where jobs have due dates but their execution may be interwoven so that there is no clear start or finish. CPM focuses on the project itself, which has a definite start date and finish date that is used to compute activity floats and level resources. This is because each specialty contractor’s detailed design, fabrication, procurement and construction process normally takes the form of a job shop, which view differs from the project view adopted by general contractors in their CPM schedule.
There is a difference, however, between the schedules prepared by the specialty contractor and the main contractor. Specialty contractors may also prepare their own schedules to meet the project’s needs. These look-ahead schedules are normally valid for up to 3 or 4 weeks out. As traditionally being practiced, general contractors would prepare project schedules to cover the entire project duration and in turn, the superintendents may create look-ahead schedules that reveal more detail on activities to be executed in the near future. These traditional systems are based on a purely hierarchical top-down approach where every project is broken down into smaller activities. Many planning systems use the critical path method (CPM) in their approach, such as Primavera Project Planner® and Microsoft Project®.

This is because there are no specific menu or feature in most scheduling software on how to create this time-based S-curve because most scheduling software were designed to track time and cost or resource together instead of separately.īased on the great demand on this issue, I have written an illustrated e-book that describes the steps involved in creating a time-based S-curve manually, as well as directly plotting it in Primavera Project Planner® software. The time-based S-curve planners or users often find it difficult to plot the S-curve directly in the scheduling software they are using. One of the reasons could be because of easy monitoring without the needs of checking and analyzing resource utilization and cost incurred. This is especially true at the beginning of a project or in smaller scale projects as often being practiced in Malaysia. However, there are occasions where projects are monitored and controlled using work-day based or time-loaded S-curve only. It plots the cumulative value of any point at the time of the analysis. With this type of bar-chart, S-curve is usually used as an illustration of the resource usage or cost analysis. Other than time, resources such as labor, material, equipment and cost can also be loaded into the bar-chart. It basically describes the amount of time (work-hour or work-day) needed to perform a task including the total time to complete the whole project. It is easy to prepare, easy to explain and easy to understand.
