Process Improvement
The initial work plan becomes the baseline for process improvement once the operation begins. Changes to the operation are made on a systematic basis, metrics are tracked so the impact of
the change can be assessed, and the work plan is updated to incorporatethe successful changes.For ongoing operations such as the precast caps, the weekly cost and schedule meetings were used to
solicit and implement improvements to the overall operation. Action items are identified and tracked with the responsible individuals identified. At U.S. 90, several improvements were made to the precast cap operation. For example, the access platforms were simplified to improve overall access and improvements were made to the methods for setting the friction collars, which reduced the manhours
required for this step in the operation. Crew sizing was also optimized.
Once the operation is completed, lessons learned and actual outcomes are documented for each of the work plans as part of the project final report. The final reports and work plans are archived as reference material with the intent that they will be used as the basis for future operations.
