Abstract:
Over the past decade, the Maryland Department of Transportation State Highway Administration (MDOT SHA) has implemented Alternative Project Delivery (APD) methods in a number of transportation projects. While these innovative practices have produced significant schedule and cost improvements, the potential benefits have not been fully achieved. This research identified the barriers and solutions to improve the APD implementation process at MDOT SHA. The study was based on structured interviews and empirical analysis of cost and time performance of DB projects that have been executed over the past 15 years. Among the results include the high correlation between efficient communication and higher project success and satisfaction. Additionally, the data analysis showed that many issues in APD projects stem from a lack of knowledge and a poor mindset regarding the transition from the traditional delivery method of Design Bid Build (DBB) to an APD method. However, the data suggests that overall project satisfaction with APD projects versus DBB projects is higher at 3.8 out of 5 vs. 3.4 out of 5, respectively. While there was a higher satisfaction for APD projects, there was also a much larger variance in the APD satisfaction compared to DBB which suggests that there is room for improvement with APD methods.
