Abstract

This paper makes a deep comparison and research on the cost of prefabricated concrete structure which is popularized vigorously by our country. By comparing the cost of three high-rise concrete residential projects with different prefabrication rates, this paper makes a detailed comparison of the total above-ground cost, civil construction and installation, and the cost of prefabricated components. On this basis analyzes the influence of adjusting prefabricated components on the prefabrication rate and the influence of prefabrication rate on the change of cost. Finally, it is discussed that the cost of prefabricated housing project is higher than that of traditional cast-in-place concrete housing mainly because of the increase of steel and concrete content of prefabricated components, transportation cost, main material consumption and comprehensive unit price. In this paper, the cost comparison and difference of prefabricated housing provides reference and reference for the future cost analysis of prefabricated housing.
