    (Universidad EAFIT, 2017) Agudelo Galeano, Sebastián; González Mazo, José Daniel; N/A
    In Colombia, the vast network of road infrastructure is old and inadequate, resulting in low average speed, higher vehicle maintenance cost, and excessive fuel cost which together have become a major hindrance to the national economic development of Colombia -- More than a decade ago, the national governments develop a national plan to improve the quality of roads in Colombia, thereby reducing the economic and social cost associated with poorly developed road infrastructure. Within the plan, construction resource management practices as defined in project contracts including subcontracting, aggregate resource - material, mixture and fuel - use & management were identified -- In this paper, these risk management issues associated with the resource management are addressed, and the current regulations that governs these issues will be reviewed -- Using economic and accounting concept of cost, project management practices will be examined to identity potential and real wastage of construction resources -- In addition, utilizing concepts of risk management, new controls and methodologies will be discussed and proposed to minimize the loss & wastage of construction resources
