Q11 Given the precedence network for a small engineering project with activity durations in working days, it is required to compute the activity times (ES, EF, LS, and LF) and total floats (TF) and then indicate the critical path. ES D EF Act FF LS TF LF 2 4 SS 1 SS1 4 G B D FS 2/ 3 A 7 H ZZ 1,4 6 FS 3 E SF 2 FF 3 F project duration = The critical path is = ES of activity B = LS of activity G= EF of activity D = TF of activity H = LF of activity F = TF of activity F=
