A cost data set is one of the cornerstones of a proper estimating and cost management system. Having a set of norms to be able to estimate and verify turnarounds has a significant impact on the cost management of these major events.
However, creating your own turnaround and maintenance database can be a time-consuming and complicated process. Data incompleteness and lack of experience in data management can hamper the development of the knowledgebase. This, combined with inappropriate tooling, makes it challenging to create a proper knowledgebase for many companies.
