Question

Ron Satterfield’s excavation company uses both
Gantt scheduling charts and Gantt load charts.
a) Today, which is the end of day 7, Ron is reviewing the
Gantt chart depicting these schedules:
◆ Job #151 was scheduled to begin on day 3 and to take
6 days. As of now, it is 1 day ahead of schedule.
◆ Job #177 was scheduled to begin on day 1 and take
4 days. It is currently on time.
◆ Job #179 was scheduled to start on day 7 and take
2 days. It actually got started on day 6 and is progressing according to plan.
◆ Job #211 was scheduled to begin on day 5, but missing equipment delayed it until day 6. It is progressing as
expected and should take 3 days.
◆ Job #215 was scheduled to begin on day 4 and take
5 days. It got started on time but has since fallen behind
2 days.
Draw the Gantt scheduling chart for the activities above.
b) Ron now wants to use a Gantt load chart to see how much
work is scheduled in each of his three work teams: Able,
Baker, and Charlie. Five jobs constitute the current workload for these three work teams: Job #250, requiring 48
hours and #275 requiring 32 hours for Work Team Able;

Jobs #210 and #280, requiring 16 and 24 hours, respectively, for Team Baker; and Job #225, requiring 40 hours,
