first activity should be framing and one can not start draywall installation without completing framing work.the next task is finishing and painting. we can carry both installtion and finishing and painting as parallel task by giving one day or two day break for the last event to ensure some part of the preceding activity will be completed so that the next task can be started
the above shown logical network is built by CPM method of project planning.
in the above network 2 days have been left with no work to ensure some part of installation of drywall to be completed to carry finishing works and also to satisfy the given condition "each activity should be finished atleast 1 day after finishing of its predecessor activity".
in the above network critical path has been shown with black line.the network is telling that after framing activity, installation, finishing amd painting of the drywall are carried as parallel activities to reduce project duration.
Therefore from the above network the total project duration is 10 days.(critical path duration)

Choose an event or significant task and prepare an activities list following a format similar to that used in the text, Table 9.3, Chapter 9, page 391. Be sure to include the immediate predecessors. Then, create a project network similar to that shown in Figure 9.7, Chapter 9, page 392. Do NOT include times for the activities and do NOT attempt to determine the critical path. Examples of events you might consider (there are many others): formal dinner for 5...
