China's experience in the development and application of construction cost engineering

Abstract

This paper provides an in-depth discussion of China's rich experience in the field of building cost engineering development and application, especially focusing on the current development of assembly building, which is the most representative of the process of building industrialization. Withits relative advantages in cost, especially its wide application in the construction projects of sheltered housing, assembly building has gradually become one of the important directions for the transformation of China's construction industry. Despite the fact that assembled buildings have demonstrated many advantages, such as reducing on-site construction pollution and shortening the construction period, challenges in terms of low technological maturity, shortage of professionals, and cost control still exist. The article further analyses the concept of building industrialization and its impact on construction cost, pointing out that although the cost of industrialized housing may be higher in the use phase, its overall cost is lower and the economic benefits are significant from the perspective of the whole life cycle. In addition, a BP neural network model is introduced in the paper to predict the cost of assembled buildings. Through the learning and training of a large number of actual project data, the model demonstrates excellent prediction ability, which can effectively assist decision makers to make an accurate estimation of the projectcost at the early stage of the project, reduce the project cost, and promote the healthy development of assembly buildings. Therefore, this paper not only provides valuablepractical experience for the development of construction cost engineering, but also lays a solid theoretical foundation for the promotion and application of assembly building.
