Abstract

The daily-incremental population of Iran and the incremental need for housing as well as the insufficient traditional construction systems of Iran have increased the tendency to use modern technologies in mass housing projects. It is tried in this research to study the effects of using modern construction technologies on time, cost, and quality of Iran mass housing projects, their problems, and ways to develop. The results of this research show that these technologies in Iran will accelerate project time up to 50% than the traditional technics. Moreover, construction costs reduced to 30% in projects with fewer housing units than the traditional technics, and costs reduced in projects with many units in total per capita. The maximum use of this technology in Iran is in the step of structure-basis and facility installation. In recent years, the entrepreneurs’ tendency has increased toward modern technologies. Based on findings, providing the appraisal motives from some institutions such as municipality will increase public interest to use these technologies in the state. Based on the decision-making matrix of multi-criteria decision-making method, the maximum effect of modern technologies on Iran mass-housing projects have higher integrity and solidity of structure, better quality, the longer life-time of structure, acceleration in construction time, better resistance against earthquake, lower target costs in mass scale, beauty and lower harmful effects on the environment, better efficiency of the installation, and optimization of building energy consumption.
