Abstract:This study was undertaken to: 1) apply a benchmarking process to identify best practices within four areas Wisconsin Department of Transportation (WisDOT) construction management and 2) analyze two performance metrics, % Cost vs. % Time, tracked by the WisDOT on American Recovery and Reinvestment Act (ARRA) projects to develop benchmarks for highway construction. The first objective involved an in-person survey of senior department staff and other experienced project managers. Survey data was collected for 45 best practices, scored, and then ranked based on three categories: general, small budget ARRA, and large budget 'Mega' projects. The second research object utilized the performance metrics of percent complete by time and percent complete by cost to generate a cumulative process curve, or S-curve. Monthly data points were collected for 283 WisDOT ARRA projects constructed in 2009 and 2010.
