The project status is as shown in Fig. 8 and Table 2. Activities B and G had completed on schedule; Activity J had an actual start; the completion of Activity N was still uncertain; and hence, for this update activity N is stretched to 3 days, which delays the start of Activity O and reduces the float for Activities N and O by 2 days. The contractor is delaying the completion of Activity N and hence the reduction in float goes against the contractor’s ATF. Thus, the value of TF for Activities N and O reduces from 9 to 7 days and the contractor’s ATF is reduced from 4.5 to 2.5 days.
