The Index System for the Development Level Evaluation of Regional Construction Industrialization: A Case Study in Jiangsu, China

Abstract

Abstract:In recent years, there have been concerns raised about construction industrialization in China, which have initiated a wave of policy change in both governmental and industrial organizations in order to change the mode of conventional construction. However, the current development level of regional construction industrialization (RCI) in China has not been well-characterized. This study screened preliminary index systems in five dimensions: technical, economic, sustainable, enterprise development and development environment. Based on the data gathered from the questionnaire surveys and subsequently analyzed, twenty-two critical evaluation indicators were identified. Analytic Hierarchy Process (AHP) was then employed to determine the weighting of each indicator. The evaluation method of the development level was formulated on the basis of the evaluation criteria. Jiangsu Province was used as an example in this study, with the development level of this province being comprehensively examined using a combination of the index system and evaluation method. The results show that Jiangsu has a relatively high RCI development level. The data from analysis scores of five dimensions and twenty-two indicators show that the index system is feasible, with evaluation results being consistent with actual practice. These findings provide a good practical reference for making decisions about how best to guide the development of RCI.

Promoting Construction Industrialisation with Policy Interventions: A Holistic Review of Published Policy Literature

“…Jiang et al [ 51 ] emphasized the importance of governmental mandatory policies and regulations in CI development on the basis of a thorough review of 85 governmental documents and SWOT analysis. On the other hand, governmental mandatory policies and regulations are listed as the most critical driving force to transfer traditional construction to CI [ 61 , 62 ] and promote CI-related technology such as building information modelling (BIM) [ 58 ].…”

“…The research community has made a significant effort in the development of novel CI technologies and high-tech supporting tools. It is important to have sufficient policy interventions to promote the adoption of these novel technologies and management systems [ 62 ]. For instance, building information modelling (BIM) is an important supporting tool in CI adoption [ 105 ], which provides precise geometry information that could be used to support the CI activities to realize the prefabricated buildings [ 58 ].…”

Comprehensive Evaluation for Real-Time Compaction Quality Using i-AHP and i-GAM: Case Study of Earth-Rock Dam

“…Therefore, reasonably considering both the properties of dam materials will help fully reflect the compaction quality. Due to its simplicity and flexibility, the analytic hierarchy process (AHP) method, proposed by Saaty [20], has been widely used to solve comprehensive evaluation problems [21,22]. In the method, the weights of the alternatives are given by the decision-making experts.…”

IoT-Based Intelligent Construction System for Prefabricated Buildings: Study of Operating Mechanism and Implementation in China

“…Prefabricated buildings, as one practice of designed building components being made in factories in advance and then transported to the construction site for assembly, have been widely promoted across the world as one of sustainable construction methods for their advantages of a short construction period on-site, high quality, low cost and less energy consumption [1,2]. It has also been reported that the global prefabricated buildings market was USD 159 billion in 2017, a substantial increase of more than 20% from the previous year [3], and which is expected to grow at a CAGR (Compound Annual Growth Rate) of over 8% during the period 2019-2025 [4].…”
