• • 15.1 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 described.

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, for Team Charlie.

Prepare the Gantt load chart for these activities.
