Submittal of Bid Proposals in Electronic Format

This synthesis will be of interest to state Department of Transportation (DOT) contract officers, program managers, and construction engineers. It will also be of interest to computer specialists and construction contractors interfacing with the state DOTs using electronic media processes. It describes the current state of the practice for submittal of bid proposals in electronic format. This report of the Transportation Research Board presents a brief introduction to the history of electronic data interchange (EDI), its relation to electronic bidding, and current applications in the transportation construction industry. The results of a literature review, surveys of state DOTs and highway contractors, and interviews with industry experts and government agencies on the use of electronic bidding for highway projects are presented. Potential benefits and concerns, plus other issues related to the full implementation of electronic bidding in DOTs, are also presented. In addition, reported common plans for near future implementation of EDI technology to electronic bidding system processes for transportation construction projects are included.

Use of Warranties in Road Construction

This synthesis on the use of warranties in road construction will be of interest to administrators, engineers, designers, and contractors involved with highway design and construction and the procurement process for these services. Experiences with use of warranties in Europe and the United States are cited and the potential impacts, benefits, and concerns of using warranties in the United States are identified. Actions needed to facilitate the use of warranties for highway projects in the United States are also discussed. The use of warranties in road construction is relatively widespread in the European highway industry compared to practice in the United States, where use has been limited....

Pavement Management Applications Using Geographic Information Systems

TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 335: Pavement Management Applications Using Geographic Information Systems examines the state of the practice and knowledge of pavement management systems (PMS) using geographic information systems (GIS) and other spatial technologies, and discusses how the technologies have been combined to enhance the highway management process. The synthesis reviews the principal issues related to PMS data collection, integration, management, and dissemination; applications of spatial technologies for map generation and PMS spatial analysis; and implementation-related issues, including approaches used for integrating PMS and GIS and the different tools used to support pavement management decisions.
