An as-built schedule documents how a project was built over time. It indicates the start and the end dates of each activity during the construction. This schedule is often used to evaluate delay and/or disruption claims. This paper describes one method to create an as-built schedule which requires minimal additional time to create but allows an enormous amount of information to be incorporated and analyzed automatically. Two software programs are required for this method - Lotus 123 and the Primavera Project Planner scheduling software. The method presented in this article offers several advantages including efficient and expedient data input, and the ability to analyze the data using a generous choice of charts and diagrams available in Primavera (P3) and Primavision. In addition, it allows automatic generation of various bar charts which show disruptions on activities by identifying active and inactive days on each activity bar. An actual case study will be used to illustrate the steps involved in applying this method.
