Conversion Between Network-level and Project-level Units of Measure for Use in a Bridge Management System


Book Description

VDOT is implementing Pontis 3.0 to provide the analytical component of its Bridge Management System (BMS). This system prioritizes bridge maintenance, repair, rehabilitation, and replacement (MRR & R) needs using cost/benefit analysis. The accuracy of this analysis depends on the condition assessment of the structure and the cost data of MRR & R options used in the analysis. For the network-level analysis a BMS provides, the focus is on what work was done to an element rather than how it was done. To standardize the MRR & R actions taken at the network level, commonly recognized (CoRe) elements have been identified and are used in Pontis. For each element, a set of feasible MRR & R actions has been defined. How these actions are accomplished is tracked on the project level. Contracted bridge work is managed using industry-standard pay items and quantities. There is a great deal of historical project-level data from previous contracts. However, there has not been any large scale network-level data collection effort. The purpose of this project was to examine cost management practices in VDOT and to develop an architecture for an automated project-level to network-level cost conversion process. This process should provide accurate updated cost data to Pontis by (1) using pay codes, quantities, and other contract information; (2) combining this information with existing inventory information and new inspection information about the structure; (3) reporting what CoRe feasible action was taken and the associated unit cost; and (4) providing this information in a Pontis-usable format. The investigation of cost management revealed a number of areas where VDOT could improve its practices. The research addresses potential remedies for some and, in some cases presents potentially viable conversion schemes.

Accelerating Transportation Project and Program Delivery


Book Description

NCHRP Report 662 describes how selected transportation agencies have reduced the time required to complete the project delivery process. This process takes new or renewed transportation facilities and services from conception to completion, ready for users. Project delivery is a primary indicator of an agency's effectiveness. Individual highway and other transportation projects are developed under programs intended to implement agency and legislative initiatives and other public policy. The way programs are organized and managed can determine the speed and efficiency of project development. Accelerating program functions can speed up project delivery. This report describes the experiences of eight state departments of transportation (DOTs) that made improvements in their project delivery and the lessons to be learned from their experiences. The information will be useful to DOT managers seeking to ensure that their agencies' organization, policies, and program operations facilitate project delivery.
