Please show steps and explain

1. Please perform forward and backward pass calculations to determine the early and late starts and finishes as well as the total float for each activity. Also highlight (with a solid line) the critical path. 2. Construct an AOA diagram of this AON diagram. 3. Use Excel to produce a bar chart displaying the early dates with a start date of Sept 26 Site Clear Excav 2 7 Survey Forms Rebar Conduit Conc 2 4 Activity OD TF ES EF LS LF Anchors 7

Solution

1.

Using the above AON diagram the tasks are defined as:

Then the pre tasks are defined:

Now we put the times and as per the following process steps calculate the ES and EF. Then we calculate the LS and LF and then track the TF or Slack as per the LF-EF.

Hence we get the following table that provides. ES,LS, EF, LF and TF/Slack

	Task
