  • While there is no one method that will fit every situation or agency, all asset management structures have certain basic elements in their approach. These include:
    -- Setting Goals and Objectives
    -- Collecting appropriate data
    -- Calculating and analyzing deterioration rates
    -- Setting performance standards and measuring progress
    -- Use of life-cycle cost analyses
    -- Developing investment strategies
    -- Selecting programs and projects consistent with the selected strategy
    -- Monitoring the results and making adjustments if necessary.

  • So what is driving the move toward asset management?
    Our transportation systems are mature ones with many roads and bridges built 30 to 40 years ago. Consequently, we are facing a period of re-investing in existing facilities rather than building new ones. This has been reflected in federal funding where they are moving from strictly capital funding to more flexible funding for preventive maintenance.
    Because of the reports I mentioned earlier, the general public expects us to spend their money wisely and efficiently. And they are demanding greater accountability.
    We have seen a new breed of leaders coming into transportation. Rather than coming from the engineering field, many of today’s leaders are coming from the political arena or business community. And they are bringing with them a sensitivity to constituents and management concepts and principles that worked in business.
    Fourth, there have been vast improvements in computers and technology that make it possible to do things today that we could never do before.
    Finally, there is the well-recognized relationship between an efficient, productive transportation system and economic growth.

Republic of Moldova Outputs…  Benefit Cost Ration (BCR)  Ratio indicating the profitability of one option relative to base option  Gives no indications of the size of costs or benefits of an investment  First Year Benefit (FYB)  FYB is defined as the ratio in present of the net benefit realized in the first year after construction  Rough guide to project timing  If FYB > discounted rate, the project should go ahead  If FYB < discounted rate the project should be delayed until it satisfies the criterion
