Abstract: Risk and uncertainty are inherent in all construction projects and can affect overall project objectives. One of the key challenges of building pipelines in Northern Alberta is weather delays; either due to extreme cold or late winter freeze. Building through muskeg terrain has its own challenges due to the need to have frozen ground to support the weight of heavy construction equipment and to minimize environmental disturbances. Constructing during an El Niño year adds further level of challenge attributed to the later winter freeze and early spring thaw. This paper presents a case study of pipeline construction during an El Niño year and is used to demonstrate the added value of using risk analysis. During this study, risk analysis was applied to assist management with assessing the probability of the contractor meeting the mechanical completion in-service date (ISD) and to adjust the execution plan. The same concept can be applied to future projects where the probability of meeting the ISD is continuously assessed and the execution plan is revisited to ensure successful completion of projects.
