A Comparative Study of the Direct Costs Between Prefabricated Housing System and the Traditional Construction Technology—A Case Study of Precast Concrete Wall Panel

Abstract

Prefabricated house as a form of housing industrialization mode not only can improve the efficiency, but also has the advantage of the comprehensive cost reduction, energy saving, environmental protection, promote the development of the construction industry. Firstly, the article introduces status of housing industrialization development at home and abroad and a comparison of the prefabricated housing system and the traditional construction technology is made in terms of cost construction and construction process. Then, the comparison of direct cost is made for 100 m2 of walls between precast concrete wall panel and the cast-in-site wall by using the method of fixed set of price. Moreover, sensitivity analysis is done. As a result, the use of prefabricated housing system on a large scale is recommended for prefabricated house developments in Chinese Mainland.
