Overview ofPresentation • Introduction
Importance of timely Maintenance • When roads are in poor condition every KZT “saved”in road conservation will cost: • KZT 3to road users in additional vehicle operating costs and • KZT 2to the road administration (or the tax payer) in reconstruction and rehabilitation costs.
Contracting out road maintenance can save a lot of money • Routine and periodic road maintenance done by in-house labor is being replaced more and more by contracts with the private sector. • Studies made by the World Bank in the 1980’s revealed that contracting out road maintenance to the private sector can reduce maintenance cost by between 30% and 50%. • Latin American countries where among the first to replace in-house labor by contracts with the private sector. • Asian countries in general are still lagging behind.
Type of contracts • Unit price contract (admeasured) • Unit rates for work items • Payments are based on quantity of completed work • Lump sum contract • Definition of total work • Payment based on single price for total work • Performance based contract • Service level criteria (performance criteria) • Fixed monthly payments if service level criteriaare complied with • Hybrid contract • Mixture of performance contract and unite price contract
Performance-Based Management and Maintenance of Roads (PMMR) • Service level criteria define the minimum conditions of road, bridge and traffic assets as well as the management and operation of the assets , leaving it to the contractor as to how to achieve them. • The contractor is free to decide • What to do • When to do • How to do • Where to do • To do the physical works himself or subcontract (with certain restrictions) as long as he meets the performance indicators during the contract period
Performance-Based Management and Maintenance of Roads (PMMR) cont. • Lump sum payments are made periodically and might be adjusted in accordance with the change of certain factors, like inflation or traffic volume. • Major emergency, rehabilitation and improvement works might be paid based on unit prices for works agreed case by case.
Performance-Based Management and Maintenance of Roads (PMMR) cont. • Deductions or penalties are being made for non-compliance with terms and conditions of contract, especially with respect to the service level criteria. • Duration of contracts should at least include one periodic maintenance cycle (4-5 years for gravel roads and 8-10 years for bituminous roads). Pure routine maintenance contracts can be 1-2 years.

Performance-Based Management and Maintenance of Roads (PMMR) is also referred to as • Performance Specified Road Maintenance Contract (Australia and New Zealand) • Highway Asset Management Contract (USA) • Maintenance Service Level Contract (Latin America)

Overview ofPresentation • Introduction • Brief history of Performance Contracts
Brief history of Performance Contracts • 1988 British Columbia, Canada • 1990 Argentina • 1996/7/8 Uruguay, Chile, Colombia, Brazil • 1995 Sydney, Australia • 1996 Virginia, USA • 1998 New Zealand • 2000 Chad • 2001 India (Karnataka) • 2001 Spain (Alava)
Examples of PMMR in Latin America (12/2001) * Cleaning of drainage system and right of way
Overview ofPresentation • Introduction • Brief history of Performance Contracts • Main reasons for implementing Performance Contracts
Main reasons for implementing Performance Contracts • Reduces maintenance cost • Provides better transparency • Improves customer focus • Improves control and enforcement of quality standards • Improves overall road conditions • Helps to reduce road user costs and road rehabilitation costs
Overview ofPresentation • Introduction • Brief history of Performance Contracts • Main reasons for implementing Performance Contracts • Service level criteria and response times
Service level criteria • Objectives • To minimize total systems cost • To satisfy the road user • accessibility • comfort • travel speed • safety • To minimize environmental impacts • Service level criteria and response times • Examples
Examples of service level criteria • International Roughness Index (IRI) • Absence of potholes and control of cracks and rutting • Minimum amount of friction between tires and road surface • Maximum amount of obstruction of the drainage system • Retro reflexivity of road signs and markings • ............
Scope (assets or services) • Drainage System • Pavement, incl. markings • Traffic assets (safety, signs, markings, signals, etc.) • Roadside Assets • Bridges • Tunnels • Traffic Services • Emergency Response • Snow & Ice Control
Examples of service level criteria (1) a asphalt; b bituminous surface treatment; A Argentina; C Chile; U Uruguay
Examples of service level criteria (2) a asphalt; b bituminous surface treatment; A Argentina; C Chile; U Uruguay
Mainly input (hours worked) or output based (lane kilometers cleared) payment with some outcome based criteria like the response time of one hour when called upon or snow level reaches 2 inches. • Pure performance contract: the contractor receives a lump-sum per year and the client calls the contactor to achieve bar pavement within 24 hrs. http://www.vmsom.com/news/pro-paper.asp
Overview ofPresentation • Introduction • Brief history of Performance Contracts • Main reasons for implementing Performance Contracts • Service level criteria and response times • Performance monitoring and payments
Quality control and assurance • Formal monthly inspections • Informal inspections • Contractors self-control system • Road user complaints
Performance monitoringInspection system in Chile • Inspections for purposes of payment done once a month taking 10% of the road network selected at random different stretches of 1 km length; • Regular inspections done once a week selecting 5% of the network at random; • Inspections due to complaint by the public; and • Follow-up inspections to verify if contractor rectified deficiencies detected by one of the inspections mentioned above.
CHILESystem of payment • During the monthly inspection the compliance of performance standards is being evaluated for each category having different importance. Based on a pre-established formula compliance is calculated as a percentage which is multiplied by the monthly payment foreseen for 100% compliance. During the first year of the contract compliance has been around 95%, mainly due to deficiencies related to road safety and right-of-way. In addition, penalties are being applied if the contractor does not rectify deficiencies within the time periods defined in the contract.
Evaluation of service level for a one-km test section (World Bank) The overall coefficient of compliance for a specific road (or road section) in a particular month is determined by calculating the simple average of the coefficients of compliance of all test sections of that month within the road concerned.
Example of penalties for not responding to rectify deficiencies within specified response times (CREMA, Argentina)
Self-Control Unit of Contractor • Own organizational structure with qualified personnel • Verifying continuously the compliance with the service level criteria • Monthly reporting of compliance to client using standard formats • Participating in monthly formal inspections
Performance monitoring by contractor Example Virginia, USA • Asset inventory and condition assessment (updated annually) • Pavement management program • Bridge management program • Safety management and traffic control plan • Emergency response plan • Hazardous materials communications plan • Customer response plan • Public information plan • Annual work plan updated every 3 months
Quality Management System ISO 9001:2000 “Quality Management System – Requirements” requires contractor to establish, document, implement, and maintain a QMS that: • Identifies processes • Illustrates sequences and interactions • Identifies criteria and methods to ensure effectiveness • Documents resources and information necessary operate, monitor, measure and analyze the processes • Defines action required to achieve the planned results and continually improve the process
