Steps for Updating a Schedule
Updating a schedule includes the following five steps:
1.
The project manager (or superintendent) prepares a list of the actual work
progress, changes for individual activities, and all related information, as
detailed previously.
The author has had experience with both private companies and public
agencies. In his experience with private companies, the scheduler represented
the construction manager (CM) at risk (which is similar to a general contrac-
tor). The author used a simple tabular report with a project title, a data date,
and a current date displayed at the top (Oracle Primavera P6 layouts, rather
than reports, were used). The table contained columns for the activity ID,
activity description, original duration, remaining duration, percent complete,
and three empty columns with the following titles: Actual Start, Actual Finish,
and Notes (Figure 7.9 shows a sample report). Other columns could have been
added, such as Budgeted Cost, Cost To Date, Cost This Period (Figure 7.10).
Activities that were completed prior to this report are usually filtered out.
The superintendent fills in (preferably in red ink) the percent complete and
actual start and finish dates. Alternatively, the superintendent may cross out
the remaining duration and provide the new remaining duration in lieu of the
percent complete. Another option is to provide an expected finish date. One
good practice is to adopt a
single criterion
—percent complete, remaining dura-
tion,
or
expected finish date—for updating activities. Computer programs can
