Inter-American Development Bank

Inter-American Development Bank

The Inter-American Development Bank (IDB) is the largest source of development financing for Latin America and the Caribbean. Established in 1959, the IDB supports Latin American and Caribbean economic development, social development and regional integration by lending to governments and government agencies, including state corporations. Economikr rendered services to IDB in economic feasibility studies, ranking & optimization and in Pavement and Bridge Management Systems, under subcontract to T&M. Samples of these projects are presented below.

Pavement Management System of Rural Roads in the Dominican Republic

This project was dedicated to creating a pavement management system for all rural roads throughout the Dominican Republic. This included the creation of economic methodology for transport sector evaluation and analysis, developing a socio-economic ranking procedure and further development of poverty indices, both of which were based on economic potential, social and other factors. The results of this project led to procedures that were later used to allocate budgets under a set of budgetary ceilings, based on IBC (Incremental Benefit Cost) multi-year optimization.

Development of an Urban Pavement Management System (PMS) for the Roads in 11 Cities, El Salvador

This dedicated PMS project covered the roads in El Salvador’s 11 major cities, including the capital, San Salvador. This large-scale national project included the development of transport models for an urban environment, economic optimization under budget constraints, life cycle cost analysis, and calibration of HDM-4 models to urban road conditions. All models created for this project were then integrated using advanced computer programming, including GIS and video. 

Development of a Budgeting System for Funding Interurban and Urban Roads in El Salvador

This project focused on creating a pavement management system for the interurban roads, both paved and unpaved, in El Salvador. The project included the development and calibration of engineering and economic models both for paved and rural (unpaved) roads. Further, it focused on creating a budget optimization method for periodic road maintenance activities and prioritization of routine maintenance activities, due to El Salvador’s limited budget for road maintenance. Three types of optimization were deployed in this project: standard budget optimization, agency cost optimization, and reverse optimization (e.g., determining the costs of raising the road network to a given user-defined level). 

Road Capacity Improvement Project in El Salvador

This project’s primary objective was to include road capacity improvement within the existing El Salvador PMS. The project included GIS integration using GPS data, interfacing with data from other software programs, economic analysis of road capacity improvement, and developing economic optimization methodologies for all of the above, that resulted in a detailed Pavement Management System (PMS).

Economic Feasibility Study of the CA-02W Road in Honduras

This project included the economic analysis of Central American Highway, in its western section in Honduras. Economic analysis was performed using the HDM World Bank model, and included several road engineering alternatives.
