Figure 13.2 Sample Three-Week Short-Interval Schedule cover the upcoming two-week period with a look back that recorded the accomplish-ments of the previous week(see Figures 13.2 and 13.3).(Figure 13.3 shows slightly more detail than Figure 13.2.1 Basically, short-interval schedules show the days of the week and the list of activities that are to be scheduled during the selected time period. Since they are used on widely varying projects,short. interval schedules are structuredin an open-ended fashion. This allows a particular type of format to be utilized onmany diflferent projects without making any modifications to the general format as the projects change.Some firms used four-week schedules in which one week do cumented the previous week'S work and the remainder planned the activities for the up coming three weeks.
The accuracy of a short. interval schedule iS directly affected by the timing of itSpreparation.Assume that a particular short-interval schedule covers two fuIl weeks ofconstruction activity.The ideal time in which to prepare this schedule would be theThursday or Friday of the week immediately preceding the scheduling period.This willresult in an accurate schedule,as only the work actually accomplished on Friday of thatweek must be estimated.If prepared a week earlier,the short-interval schedule may notbe current because of the variability of the work actually performed between the timeof schedule preparation and the beginning point of the short.interval schedule.
Short-interval schedules are prepared each week.Mthough the foCUS of discus-sions at meetings involving the short-interval schedules tend to emphasize the activi-ties and events to take place during the upcoming week,looking ahead two or threeweeks forces all parties to begin to plan for future developments on the project.If acrew was to produce at a faster.than.planned rate,the schedule for the second weekwould be activated early.At any rate,looking a few weeks into the future serves a valu-able function in getting all parties to begin devising their own work plans.
