Abstract
Construction projects consume a considerable amount of resources and funding. Cost control is an essential process to attain project success and enhance its value. Many studies have been dedicated to studying how value engineering (VE) can be used to control construction costs. However, limited studies can be found on the integration of building information modelling (BIM) and VE for better cost control and optimization. The main purpose of this study is to determine how BIM can be integrated with VE and illustrate the benefits of this integration. The study proposed a framework based on the analytic hierarchy process (AHP) and the entropy method to calculate the weight and coefficient. A case study method of a high-rise building project in China was used to validate the framework and demonstrate how BIM can be integrated with VE. The data were collected through document analysis, interviews, and a questionnaire survey targeted on project participants. The findings show that the integration of BIM in VE facilitates design modification and information extraction such as cost data. Using this approach showed a saving of 10% in project cost and duration. Besides, the overall quality and performance of the project have been enhanced. The findings show the significance of integrating BIM and VE to enhance building project functionality and performance before, during, and after the construction stage. This study contributes to providing empirical evidence of the advantages of this integrated approach including a better understanding of project components and requirements, easy access to project data, comprehensive weight and function analysis, easy validation of recommended solutions, and ability to virtually evaluate design changes and construction site planning.
Highlights
Regardless of the rapid development of technology and digitalization in this era, construction projects are still facing many fundamental issues such as project delay, cost overrun, and low efficiency and performance [1, 2]. e construction industry in China, and many other countries, has been criticized to have many participants, long project cycle, high risk and uncertainty, lack of coordination among construction players, and lack of data sharing and resource integration [3, 4]
An integral step involved in the improved value engineering method is to develop weight and project value indices using the analytic hierarchy process (AHP) and the entropy method, as shown in Figure 2. e selection of building elements to be evaluated was conducted by decomposing the building components into elements based on the hierarchical analysis of the project. e new method is validated throughout the case study
Discussion and Recommendations e practical procedures to enhance the project value, to reduce the completion time, and to enhance the overall quality of the project were identified based on the result of this study. e integrated approach of building information modelling (BIM) and Value engineering (VE) has proven effective in enhancing the project value and control project cost. e current study presents the following recommendations as a lesson-learned set realized as a result of conducting this case study. e recommendations provide practical steps to enhance the project value, reduce the completion time, and enhance the overall quality of the project
Summary
Regardless of the rapid development of technology and digitalization in this era, construction projects are still facing many fundamental issues such as project delay, cost overrun, and low efficiency and performance [1, 2]. e construction industry in China, and many other countries, has been criticized to have many participants, long project cycle, high risk and uncertainty, lack of coordination among construction players, and lack of data sharing and resource integration [3, 4]. E construction industry in China, and many other countries, has been criticized to have many participants, long project cycle, high risk and uncertainty, lack of coordination among construction players, and lack of data sharing and resource integration [3, 4]. In today’s construction industry where the market is becoming saturated and the economic situation is grim, most construction companies are facing a survival crisis [2, 5, 6]. As construction projects consume a large sum of resources and investment funds, cost control is becoming one of the main criteria to determine their success. Value engineering (VE) is one of the common cost control methods used in construction and other sectors such as manufacturing. Construction cost control system based on BIM and value engineering.
