TopConstruction Cost Optimization Of Prefabricated Buildings Based On Bim Technology
With the progress and rapid development of science and technology, people are paying increasingly more attention to environmental protection, green initiatives, and low-carbon ecological issues (Shang & Lv, 2023). The traditional construction industry has serious environmental pollution, serious waste of resources, and low construction efficiency (Wu et al., 2023), all of which have become obstacles to the development of green buildings and sustainable economic development, and the construction industry is facing new opportunities and challenges (Ebekozien et al., 2021). This is particularly true with the rapid development of prefabricated buildings. Their characteristic low carbon and positive influences on environmental protection ensure the progress of these projects (Lin & Zhang, 2023) and have attracted the wide attention of engineers from all over the world. Consequently, China's construction industry has experienced a refresh in development thanks to the sustainability and progressive direction of prefabricated buildings (Zhang et al., 2023). Prefabricated buildings have been fully developed, and are now mainly used in commercial housing (Masood et al., 2023). This study found that the cost of prefabricated houses is only half of the cost of traditional cast-in-place houses. Therefore, prefabricated buildings have become the inevitable development trend across the construction industry (Han et al., 2023). Figure 1 shows the change in scale of China’s prefabricated building market from 2010 to 2020 and exhibits just how rapidly the assembled building market in China is growing year by year.
With this rapid development of China's construction technology, the engineering construction industry quickly moved from swift growth to stable development (Zhang et al., 2023). Urban construction has experienced a shift from pursuing modernization to paying attention to green initiatives, environmental protection, smart building, and optimal livability. The traditional construction mode no longer meet people's requirements for building quality and efficiency. With an increase in labor costs, the demand for quality of life has increased (Zhang et al., 2023). At the same time, with the improvement of people's requirements for protection of the environment and the prefabricated construction of green, environmentally friendly and efficient buildings, the development and implementation of prefabricated buildings have become the top priorities for the country. In the process of actively promoting prefabricated buildings, the components are manufactured in advance and then transported to the construction site for installation. This method greatly shortens the construction period, reduces building costs, and minimizes environmental pollution and material loss (Zhang et al., 2023). Figure 1 shows the scale change of the prefabricated building market in China from 2010 to 2020.
