Abstract: When the baseline schedule for a project does not include or reflect all of the work actually required, use of that schedule and subsequent updates for delay analysis will not provide accurate answers. An example would be the situation where an engineering, procurement and construction (EPC) contractor is assigned procurement contracts which provide inaccurate quantities of work to be installed. As a result, the baseline project schedule would not properly reflect the full work to be performed and may not correctly forecast the critical path or duration, both of which could be substantially affected by the significant undisclosed quantity changes in the work. Had the correct scope/quantities been known and disclosed from the beginning, the project would have been scheduled and planned in a significantly different manner. This paper discusses a method that allows a proper analysis of both delay and the actual critical path in such a situation. The method includes correcting the baseline schedule using a time impact analysis and then progressing the contemporaneous updates as modified for the additional quantities of work. It is a hybrid approach using a combination of Method Implementation Protocol (MIP) 3.3 and MIP 3.7 from AACE International Recommended Practice (RP) 29R-03, Forensic Schedule Analysis.
