Abstract

North Carolina Department of Transportation (NCDOT) projects with construction costs of $50 million or more, known as mega projects, make up more than 50% of their total construction expenditures while representing less than 10% of the total project count.  The estimated let dates and construction expenditures for these projects can vary significantly.  This paper identifies two ways of monitoring mega projects to quickly recognize and mitigate developing problems.  The research methodology included an extensive literature review and interviews with 23 agency subject matter experts and construction contractors.  The paper contributes to the body of knowledge through collecting and analyzing data pertaining to strategic milestones and expenditure payouts for transportation mega projects.  The paper also contributes a new checklist that enables agencies to identifying projects that are at risk of let delays during preconstruction and a new approach for identify projects that are not meeting their original construction performance baseline goals (and require intervention for corrective action) during construction, both of which can result in costly delays.
