Abstract: Many projects consist of strings of activities that are repeated multiple times to generate the full schedule, a good example being a multi-story building.The foundation is subdivided into similar sections, comprised of excavation, layout, pile driving, pile cutoffs, pile caps, grade beams, and backfill.A common approach is to develop the first section and duplicate it, changing the horizontal label, or elevated floors in a vertical environment.This is quick and provides good quality control if done correctly.
The risk to this effort is that the schedule development session is used to establish the standard fragnet in the first section and the sequencing between sections, then duplicated and validated by the construction management team, however, when the full schedule is reviewed, it commonly is not acceptable.This can be because the team has a gut feeling about the overall duration of the entire foundation or the full multi-story facility.
The author worked out an approach that improves this method and minimizes the rework necessary when the final product is not acceptable because that rework might be only 15 changes on the first elevated floor but 300 changes for a twenty-story highrise.It can be faster to delete all the duplicated floors, make the changes on the single floor and duplicate it again.This paper will demonstrate the process to enable a standardized approach for an efficient schedule development process which the author calls an “outline schedule development.”
