Abstract: Proving lost productivity is a challenging task in construction claims, especially in the context of pervasive disruptions and cumulative impacts. Although the measured mile method is generally the most accepted approach to quantify loss of productivity in construction projects, its applicability is often hampered when suitable data is not readily available; further, it is not uncommon that its application is abandoned due to the perceived difficulties in proving similar work, and distinguishing the unimpacted, lightly impacted and heavily impacted work. Yet even in these cases, project specific productivity differential methods based on the measured mile concept, are favored because it compares actual performance of similar work on the same project while minimizing the reliance on the budget. Through case studies, this paper will demonstrate how to combine various techniques to establish a baseline, which would extend the use of the measured mile concept to projects on which the measured mile method may intuitively appear inapplicable.
