Abstract:
One of the major responsibilities of state Departments of Transportation (DOTs) is to maintain their road assets so

that road users can travel cost effectively, safely, and in a timely manner. Maintenance projects can be performed

either by using the DOT’s own workforce or by outsourcing to private contractors. Recently, some state DOTs have

started using performance-based contracting for maintenance projects. In this study, benefits of these types of

maintenance contracts were collected by conducting a national survey. Moreover, this study compared the use of

the state force (SF) and private contractors in Nevada regarding the cost and quality of such maintenance activities

as chip seal, striping, culvert cleaning, and sweeping. Results showed that state DOTs were highly satisfied with

work performed by the state force, followed by private contractors when using method-based contracting and

performance-based contracting. The cost comparison showed that chip seal, striping, culvert cleaning, and street

sweeping performed by SF was less expensive than when performed by private contractors. Similarly, the quality

of chip seal, culvert cleaning, and street sweeping was better when performed by SF versus contractors. However,

the quality of striping work performed by contractors using the performance-based contracting (PBC) method was

better than when performed by the SF. Recommendations for future study include collecting comprehensive cost

and quality data for stretches of roads that are similar.
