Abstract

Paying attention to the science of management, generally, and especially to the knowledge of Project management and leadership, is absolutely necessary in national development programs in every country. Like other fields of industrial development, the progresses of the systems of project management have been considerable. In common traditional systems, there were no kind of some services like scheduling, constructability studies, value management studies, and researches on the ways of reducing the direct costs of the project and as a result, problems like high costs, low quality and no unacceptable delays, were happening frequently. Definition of construction management agency reduced many problems, but having no responsibility and taking no kind of risk against the client caused this type of management to be unusable. So, the construction management at risk (CMR) was defined. In different countries, there are many titles for the construction managers, but all of them have two agents and the risk element in common. Also in Iran, in addition to the clients, there has been defined an official title named Management contracting, or the fourth factor in the national executive and technical system. Having little knowledge about the essential reasons of CMA and CMR definition, with the fundamental goals of these types of managements, and perhaps, the right method of transition, from the three-factor system, to the four-factor one, many of Iranian management contractors only use some limited aspects of the construction management. This research, generally, tried to define management groups of civil projects and study their differences and similarities, according to the common international standards, and then looked through the characteristics of the management contracting in the Iranian executive and technical system to find the difficulties and problems which the management contractor are dealing with, and finally, evaluated the ideas of the experts of these fields (like the construction management companies, and those contractors with such former experiences) through a survey. Applicable suggestions to use the CMR in Iranian contexts, to improve the qualitative status of the projects, and to reduce the imperfections and delays, are the expected results of this research.
