Mathematical Model for Optimization of Construction Contracting in Housing Development Project

This article presented a method for solving a construction planning problem in a housing development project using a mathematical model which is an integer linear programming for dividing house construction jobs to three contractors in a project case study. 169 units of the house in the project would be constructed by the three contractors in conventional construction method and precast method. The results found application of the mathematical model was applicable. The mathematical models were formulated, minimum construction cost of the project was 417.69 million baht (M$13.92), and within the total project duration of 72 months. Conclusions and recommendations were discussed in this research.
