In our fifth article looking at the 14 point check we described how we checked Hard Constraints, in this post we are going to take a look at High Float.
The DCMA criteria states that the total number of activities with float greater than 2 months (44 working days) should not exceed 5% of the total number of activities in the schedule.
High Float Check
To check this is Primavera P6 we used the following steps:
Step 1. Add the Total Activities column in the Project view, make a note of the Total Activities in the schedule.
Step 2. Create a new report using the Report Wizard, select Activities as it is activity data we require in the report.
Step 3. Add the Free Float column as we are looking to find out how many activities have a float of over 44 days. Select Filter and create a filter to show only the activities with a High Float of over 44 days.
Step 4. Type in the report name and run the report. As we want the report in Excel select ASCII and ensure that the Text Qualifier is set to “.
Step 5. The report will open in Microsoft Excel, highlight the High Float numbers and make a note of the count. Divide the count of the High Float activities by the total number of activities.
If the percentage is 5% or lower than the criteria has been met, if higher than 5% then the schedule may require a review.
There are a further 13 checks prescribed by the DCMA which along with the Logic Check will be detailed out in further supporting documentation and video tutorials at http://www.myxacom.com where knowledge is no weight to carry.
