Abstract: This presentation will review the construction claims doctrine of concurrent delays and present the use of linear scheduling method, coupled with data-driven event information from construction daily work reports as a means to quantify the impact of concurrent delays. It will go on to provide a model for apportioning the concurrent delays between the owner and the contractor through the use of visual modeling that permits both sides to see how various concurrent delays relate to the overall delay profile. The presentation will demonstrate the approach using actual data from a $500 million earthen dam project where concurrent delays for differing geotechnical conditions, weather, quality control and a labor strike impacted progress. The approach will prove useful as agencies, consultants, and contractors measure the impact of the COVID pandemic on projects that were ongoing when the restrictions were imposed.
