AFFORDABILITY AND COST RELIABILITY PROCEDURES OF INVESTMENT AND MAINTENANCE ROAD PROGRAMS

The objectives of highway investment and maintenance programs are to improve safety and to reduce overall road transportation costs, including vehicle operating costs, travel time, and recurrent routine maintenance expenditures. The HDM-4 model defines priorities for road investment programs and the computerized routine maintenance management system (RMMS) defines priorities of routine maintenance works. Affordability, economic and financial feasibility considerations dictate the characteristics of selected investment programs: (1) Periodic Maintenance, defined as an investment that extends the life expectancy of a roadway from three to seven years; (2) Rehabilitation has a life expectancy of seven to ten years, and (3) Road Improvements for safety or congestion reasons, has a life expectancy from 10 to 15 years. The expected life is usually closer to 10 years (the lower level) due to materials, environmental, construction quality, and most important due to budget constraints of IADB member countries. The HDM 4 model considers safety issues, rehabilitation and maintenance costs, and supports the selection of the road standards and its useful life expectancy. The RMMS supports the administration (planning, design, and supervision) of routine maintenance activities with life expectancy of three months to three years, in Jamaica, Trinidad and Tobago, and Guyana. Affordability is the major concern of annual planning (network level) and weekly/monthly programming (project level) of routine maintenance work under budget, social and environmental constraints. Under such constraints, the first priority is given to highway safety activities, and then to drainage activities, and finally, if affordable, to the quality of road performance. Cost effectiveness and cost reliability considerations of road and bridge investment and maintenance works include using competitive and lump-sum procurement procedures of construction works and consultancy supervision services, using new engineering techniques that maximize the use of the existing pavement materials and minimize environmental hazards, using detailed engineering and environmental designs, using project level quality control and quality assurance procedures, using value engineering; pay-equations; bonus and penalty procedures; using extended maintenance warranties; and most important, promoting stakeholder partnership culture: agency, users and affected communities.
