Abstract: The US Army Corps of Engineers, New Orleans District, presents this cost and schedule risk analysis (CSRA) report regarding the risk findings and recommended contingencies for the Mississippi River Ship Channel, Gulf to Baton Rouge, LA General Reevaluation Report. In compliance with Engineer Regulation ER 1110-2-1302 CIVIL WORKS COST ENGINEERING, dated September 15, 2008, a Monte-Carlo based risk analysis was conducted by the Project Development Team on remaining costs. The purpose of this risk analysis study is to present the cost and schedule risks considered, those determined and respective project contingencies at a recommended 80% confidence level of successful execution to project completion. MRSC, Gulf to Baton Rouge, LA, project is a deep draft navigation channel, providing deep draft navigation access to ports located along the Mississippi River in Southeast Louisiana. The project area begins near Baton Rouge, Louisiana beginning at river mile (RM) 232.4 Above Head of Passes (AHP) and extends to the Gulf of Mexico ending at RM 22 Below Head of Passes (BHP). The channel services four of the top ten ports in the United States: the Port of Greater Baton Rouge (Port of Baton Rouge), the Port of South Louisiana, the Port of New Orleans, and the Plaquemines Port, Harbor and Terminal District (Port of Plaquemines). The Port of South Louisiana is the largest port in the nation in terms of tonnage. The non-Federal sponsor (NFS) is the Louisiana Department of Transportation and Development (LaDOTD). The current project base cost estimate for the construction part, pre-contingency, approximates $156M. Based on the results of the analysis, the Cost Engineering Mandatory Center of Expertise for Civil Works (MCX located in Walla Walla District) recommends a contingency value of $35.9M or approximately 23% of the remaining construction cost at an 80% confidence level of successful execution. The most likely constant dollar program year (First Cost at FY18 price level) is estimated at approximately $195.4M, including a total contingency value of $36.5M. Cost estimates fluctuate over time. During this period of study, minor cost fluctuations can and have occurred. For this reason, contingency reporting is based in cost and percent values. Should cost vary to a slight degree with similar scope and risks, contingency per cent values will be reported, cost values rounded.
