Answer #1

The Gantt Chart is prepared considering Immediate predecessor and Duration, each cell under days contains number of resources

Before Resource leveling, Project needs 12 days time to complete

Days with resources
Activity Immediate Predecessor Duration Required Resources 1 2 3 4 5 6 7 8 9 10 11 12
1 --- 4 1 1 1 1 1
2    ---- 5 2 2 2 2 2 2
3 1 4 2 2 2 2 2
4 1,2 5 1 1 1 1 1 1
5 2 3 2 2 2 2
6 3,4,5 2 2 2 2
Total Resources Each Day 3 3 3 3 4 5 5 5 1 1 2 2

After Resource leveling, as there are three resources available on each day

Project needs 14 days time to complete,

After Resource level
