Report of Construction Project Network Diagram - Essay Example

In the context of this report, the project manager of Company A had initiated with his team the use of network diagram in order to acquire an accurate calculation of the whole duration of the project. Each individual activity to be undertaken was given a specified time of completion before starting the next activity. In the analysis done using the said instrument, there are two factors to consider in determining and calculating the whole duration of an activity. These are the forward pass – the early or late start and backward pass – the early of late finish.

The critical path was chosen from the longest duration taken after calculating the earliest and latest event times in order to allow adjustment which activity needs speed up. Float was also calculated using the network diagram in order to determine the duration of activity delay that the project can permit before the project becomes late. A Gantt chart will provide a clear view of the critical path in the project. . ws the sequence of the activities or tasks to be carried out, the amount of time needed to complete the activity as well as the whole project, the dependencies of activities and which activities need more attention.

It is widely used by many project managers because it helps them to identify the most efficient sequence of events within the required time for the completion of any project. Example of network diagram can be shown in the succeeding part of this report. 3.0 Network diagram analysis Analysis of the network diagram is very necessary to evaluate the sequence of the activities and to construct a network with a timeline for the project. In order to carry out the analysis successfully, the project manager should consider the following fundamental steps: 1.

Draw the calculations of the earliest and latest event times. 2. Draw an activity analysis table showing the results found which include the activities, duration, and earliest and latest event times. 3. Calculate the float, free total and independent float of each activity. 4. Produce a Gantt chart showing the timeline of the project’s activities. 5. Produce a histogram of all activities resource requirements. As noted by the project manager each activity needs at least one work crew. 6. Carry a resource leveling exercise to produce a smooth resource histogram.

–Within the constraints of the critical path duration found- 3.1 Redrawing the diagram The figure 1(network diagram) below shows a simple example of network diagram and the calculation of time duration of the project using the forward pass and backward pass method of time management. It also exhibits the dependency of each task to be undertaken for the accomplishment of the project. Base on logical explanation, the predecessor task/activity should be
