Critical Factors Influencing the Sustainable Construction Capability in Prefabrication of Chinese Construction Enterprises

Abstract

Compared with the conventional cast-in-situ method, prefabricated construction (PC) is a sustainable construction method. In China, the sustainable performance qualities of PC—such as its improved quality, lower cost and shorter turnaround—have barely been achieved. This is likely attributable to the weak sustainable construction capability of construction enterprises in undertaking PC projects. This study observed that there is relatively scant research on critical influencing factors relating to this capability, after investigating the most recent literature about PC development obstacles. Without a clear understanding of this knowledge, construction enterprises are unlikely to formulate effective measures to enhance their sustainable construction capability to tackle efficiency, cost, risk, and broader performance issues in PC. Therefore, this study identified 27 factors from the literature and interviews, ranked these factors using the Entropy method and the fuzzy analytic hierarchy process (FAHP), examined the top five critical factors, and discussed the problem-solving measures. This study drew the conclusion that construction enterprises should focus on PC business scope expansion, project delivery quality improvement, and technology investment and innovation, as well as the return on investments in technology. It is also suggested that incentivised strategies be formulated by the Chinese government in order to improve industry practitioners’ capability of implementing sustainable PC projects. This will eventually expedite the industry’s transformation towards leaner, more efficient and sustainable practice.

Regional Variation in the Carbon Dioxide Emission Efficiency of Construction Industry in China: Based on the Three-Stage DEA Model

“…Capital is the critical strength to prompt the development of construction industry. Scholars [39,40] select assets of construction enterprises as the Capital input variable to calculate the efficiency of construction industry. Following the scholars' researches above, the assets of construction enterprises in each province is selected as the Capital input variable.…”

Scenario-Based Comprehensive Assessment for Community Resilience Adapted to Fire Following an Earthquake, Implementing the Analytic Network Process and Preference Ranking Organization Method for Enriched Evaluation II Techniques

“…Empirical analysis is a widely implemented method in a larger number of articles related to comprehensive assessment (e.g., He and Chen [88,89], Moghayedi et al [90], Dang et al [91], Olawumi and Chan [92], Yu et al [93], etc.). The processes of empirical analysis include two parts.…”

Evaluating Decision Making in Sustainable Project Selection Between Literature and Practice

“…Figueiredo et al [15] also used the fuzzy AHP to select between different construction projects based on the sustainability of the materials used in these projects by ranking a list of five selection criteria based on importance in the selection process. Dang et al [19] utilized the FAHP to determine the most important factors impacting sustainability in prefabrication construction projects in China. Dimić et al [20] developed a sustainable project selection tool using the fuzzy AHP by developing a ranking for key sustainable selection criteria in Serbia.…”
