"This synthesis examines current performance-based management practices that are applied by state departments of transportation (DOTs) in highway maintenance and operations (M&O). Past studies have focused on the elements that make up a performance-based M&O approach, such as condition ratings, levels of service, performance measures, and threshold values. This study focuses on how state DOTs actually use performance-based measures to manage their highway programs."--Preface.
Road asset management is one of the top priorities of the Central Asia Regional Economic Cooperation (CAREC) Transport and Trade Facilitation Strategy 2020. The implementation of performance-based road maintenance contracts (PBCs)—an essential element of road asset management—promotes effective and efficient maintenance of road networks. Well-designed PBCs keep roads in predefined good condition at relatively low cost. This guide aims to help policy makers in CAREC member countries understand and implement PBCs. After a brief history of the development of PBCs, it discusses the various types of PBCs and their relative advantages and disadvantages. It highlights PBC implementation in selected developed, developing, and transitional countries, including CAREC member countries, to illustrate best practices.
Abstract: Performance-based maintenance contracts (PBMC) for highways are increasingly becoming an attractive mechanism for transferring activities traditionally undertaken by the public sector to private entities. Increased financial pressures on governments, demands for improved service levels by highway users, and the operational efficiencies offered by the private sector, all create a strong business case for PBMC. In order to enable government road agencies and private sector investors to engage in the use of PBMC, there is a need for quantitative tools that allow both entities to 1) Properly structure the PBMC in terms of risk allocation, 2) Develop appropriate levels for service level penalties and incentives in the contract, 3) Determine appropriate targets for highway level of service, and 4) Determine the most cost-effective set of road maintenance and rehabilitation (M&R) activities to be undertaken throughout the duration of the contract. This research developed a GIS-based Integrated Highway Asset Management System (IHAMS), which extends typical functionality of traditional pavement management systems to cover specific contractual requirements of PBMC. The system allows the analysis of both network-level and project-level asset management decisions. Defect-specific pavement deterioration models are developed using multivariate regression. Stochastic network-level deterioration models are developed using markov chains. Life cycle costing models are developed to cover specific financial obligations in PBMC like penalties and incentives, in addition to traditional M&R expenditure. A GA-based optimization modules is used to trade-off various decision scenarios that are beneficial to both road maintenance contracts and road agencies. A case study for the Cairo-Ismalliyah desert highway is used to demonstrate the capability of the system.
This book focuses on the aspects of contracting contracts, basically related to road construction and management contracts. The book presents an analytical study of Performance-Based Road Management and Maintenance (PMMR), Funktionsbauvertrag (FBV) (Function-Based Construction Contract) and Public Private Partnerships (PPP). A separate chapter is also included about the comparative study of these contract types. The book provides useful material for university libraries, construction companies and government departments of construction.
Under the CAREC 2030 framework, a regional trade strategy will provide a more coherent approach to strengthen trade and enhance growth potential of CAREC countries. The CAREC Integrated Trade Agenda (CITA) 2030 aims to support CAREC countries in integrating further with the global economy through trade expansion from increased market access, greater diversification, and stronger institutions for trade. Taking into consideration the countries' capacities and varying levels of progress, CITA 2030 will be implemented in a phased and pragmatic approach including through a three-year rolling strategic action plan.
INDOT initiated a study to investigate Performance Based Contracting of maintenance operations. One of the main impetus for the study is that INDOT started a ten year road building program called Major Moves that will add over 1900 lane miles to the current network. With this addition and coupled with a trend of reduction in maintenance personnel, INDOT is planning how maintenance will be performed. One viable option is the use of performance based contracting (PBC). This study has evaluated many aspects of PBC and the current INDOT maintenance program. PBC is being used extensively in some states while other states have tried and backed away for various reasons which are explained in the report. Due to higher costs experienced with PBC and the fact that long term contracts lock in prices leaving agencies with no flexibility to reduce during economic downturns; the report is not recommending PBC to INDOT. What is recommended is that INDOT should: establish a LOS program; develop and test snow and ice removal subcontracts; and further develop a hybrid maintenance program where private contracts are used to supplement INDOT maintenance force.
The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.
TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 330: Public Benefits of Highway System Preservation and Maintenance examines the current practices for identifying, measuring, and articulating the public benefits of highway system maintenance and operation, and of communicating those benefits that are understandable and meaningful to stakeholders--road users, elected officials, and others who have an interest in the system's performance.
