Given: Activity B must start one day before activity A ends; Activity C has a lag of 1 day (F/S)from the previous activity; Activity D must start at the same

time as Activity B. a) Develop the Gantt chart for the activities listed in the table for the shortest possibleproject duration. (you could use excel as shown in class or draw the chart on paper). b) Find the cost per day and plot the cumulative project cost vs. time curve for this project.(S-curve). c) Allocate the labor and identify conflicts if maximum 16 laborers are available. Suggest one workable solution and if possible, without extending the project deadline! Draw your solution into a Gantt chart.
