Gantt charts break down the project into individual tasks, each of which is represented by a horizontal bar. The timescale of the project travels from left to right, with the left edge of the bar representing the start date of the task and the right edge of the bar representing the completion date. The bar length between the start and the end makes up the duration of that specific task. Arrows are typically drawn from the end of one task to the start of another task that is dependent on the task that proceeded it (predecessor to successor). Similar to the CPM method above, a critical path will become apparent based on the duration of the various linked project paths. Creation of a Gantt chart is rel...

Also read Critical Path Method ( Copyright ©   Arch Media Group LLC) The critical path method, abbreviated as CPM, is the most commonly used type of scheduling technique in the construction industry. The critical path method is built around the use of predecessors and successors for each construction task needed to accomplish the job. Most tasks (except the initial task) will have one or more predecessors that need to be accomplished before that task can start. If we select a certain task, such a framing a house, we need to determine what must occur before the framing can be constructed. In this case the ground floor slab will need to be finished before the framing can be placed on top of it. Therefore, creation of a ground floor slab is the predecessor of the house framing task. Conversely, framing the house is a successor of the ground floor slab construction. Following the placement of tasks in the schedule, along with the creation of linkages between the predecessor a...
