Determination Of Financing Method For Mass housing LSF Project

Light Steel Frame System (LSF) as a novel construction system is used in many developed countries such as USA, Canada and Japan but it is not tangibly requested in IRAN. Lack of knowledge in engineering, contractors and employers to this system is the main cause of little attention to it in IRAN. Considering the LSF system characteristics, mass housing project can be used as the main application of this system. Hence, dealing and managing the LSF operational and financial risks in mass housing projects is the main contribution of this paper. This system is used for implying of short-rise and mid-rise buildings (up to five floors). For Successful mass housing execution in LSF structures, exact risk identification and selection of execution method will be indispensable. selection of investment method is important therewith. So, in this article, model for selection of LSF mass housing system financing method respect to execution and economical risks is represented. In this model effective risks are determined by expert opinion and its uncertainty is modeled by normal distribution. Then for each method IRR index is calculated. In this article, 5 methods of investment considered and Public-Private Partnership (PPP) method is introduced as financing method with maximum IRR.
