Abstract. Building Information Modeling (BIM) has had a profound effect on the construction industry. It has greatly improved coordination among stakeholders, enhanced productivity, and increased profits. However, many factors still limit the application of BIM in the construction industry. This study conducts a literature review to identify these negative factors. Firstly, twenty-two sub-factors are identified and classified into five categories: Technology, Cost, Management, Personnel, and Legal. Secondly, some suggestions for eliminating these limiting factors are given. Finally, the study also identifies further research directions for improving BIM theory and applying BIM technology widely and successfully. The results of this study will provide support for practitioners who are using or plan to use BIM.
ABSTRACT. Governments worldwide are keen to encourage PPP schemes, however PPP is not a foolproof business. Many local governments and private investors have suffered severe or trying experiences. In this research, 10 case studies were conducted to identify the obstacles and difficulties for successful implementation of PPP projects from the perspective of government guarantees. These PPP projects include two water supply plants, two sewage treatment plants, two power supply plants, two highway projects, and two bridge projects. The findings obtained indicate that the local governments are familiar with "the type of guarantees" to provide to the private investor but they are unsure of the "amount" that should be given. Many PPP projects have therefore been heavily criticized for over benefiting the private investors as the government provides them with too many guarantees. The inappropriate guarantees offered by the government are regarded as one of the root causes of PPP projects' failure. The lessons learned are valuable for determining appropriate government guarantees for future PPP projects and broadening the opportunities for infrastructure development with PPP procurement model.
Traditional construction material procurement is being replaced by electronic commerce construction material procurement now. Building Information Modeling (BIM) has shown benefit and practical value in construction material quantity takeoff and cost estimate. However, very few efforts have been directed to the application and integration of BIM in e-commerce material procurement.The author compares the present commercial BIM and non-BIM based quantity takeoff and cost estimate software, presents one solution to link the BIM with RSMeans Unit Price cost data to generate more accurate cost estimate reports, identifies the possibility and potential benefit of integrating BIM and e-commerce software solutions in material cost estimate and procurement process, designs one weight coefficient based model to evaluate the performance of material suppliers, proposes a framework to integrate BIM with e-commerce in material procurement and supplier performance evaluation process, and develops a preliminary display version of BIM integrated with e-commerce software system. BUILDING INFORMATION MODELING INTEGRATED WITH ELECTRONIC COMMERCE MATERIAL PROCUREMENT AND SUPPLIER PERFORMANCEMANAGEMENT SYSTEM
PurposeThe purpose of this paper is to identify risk factors in building information modeling (BIM) technology application, analyze the correlation between risk factors, and find the most influential risk factors using interpretative structural model (ISM), put forward a response to targeted suggestions, and provide a reference for widespread BIM technology application.Design/methodology/approachLiterature reviews, ISM, a questionnaire survey and expert interviews were used in this paper. First, the risk factors of BIM technology application and their relationships were determined by consulting the relevant BIM literature. Second, to more intuitively reflect the relationships between risk factors, an ISM model based on expert interviews was established to structure the explanatory relationships and hierarchical relationships between factors. Finally, a questionnaire survey was conducted for relevant practitioners, and a scale was designed to evaluate the risk factors of BIM technology application to determine the risk factors that have a greater impact on implementing BIM technology.FindingsThe root risk factors of BIM technology consist of unclear data ownership, incomplete standard BIM systems, lack of industry insurance, lack of BIM technicians, lack of BIM project practice experience, BIM infrastructure preparation, inconsistent thinking about BIM from project participants, changes in delivery mode and software function problems.Research limitations/implicationsThe risk-sharing of BIM technology and the analysis of responsibilities, rights and benefits of all parties in a BIM project can be used as future research directions to solve higher management problems.Originality/valueThis paper describes the risks of BIM technology application for related researchers and provides another research train of thought for the follow-up studies.
The construction process plays a key role in sustainable development of the environment. With the concept of sustainable construction being put forward in the world, some countries released green construction standards to strengthen the requirements in the construction phase. Green construction code checking needs to integrate semantic information embedded in green construction standards and model information involved in Industry Foundation Classes (IFC) and/or Model View Definition (MVD), which are generated separately and lead to difficulty in information integration for green construction code checking. At present, the existing code-checking methods cannot be directly used for green construction. Related practitioners need an efficient and convenient method for green construction code checking urgently. To ameliorate this situation, this research proposes an innovative approach to organize, store, and re-use green construction knowledge by combining mvdXML and semantic technologies. The code checking of green construction is classified into four types based on the difficulty level to meet the requirements of the clauses in green construction standard. Depending on the characteristics of each inspection type, mvdXML or semantic technology is adopted for the appropriate inspection type. This paper demonstrates the deployment and validation of such automated checking procedures in a case study. Based on these experiences, a detailed discussion about the identified issues is provided as the starting point for future research.
The expansion of scale and the increase of complexity of construction projects puts higher requirements on the level of collaboration among different stakeholders. How to realize better information interoperability among multiple disciplines and different software platforms becomes a key problem in the collaborative process. openBIM (building information model), as a common approach of information exchange, can meet the needs of information interaction among different software well and improve the efficiency and accuracy of collaboration. To the best of our knowledge, there is currently no comprehensive survey of openBIM approach in the context of the AEC (Architecture, Engineering & Construction) industry, this paper fills the gap and presents a literature review of openBIM. In this paper, the openBIM related standards, software platforms, and tools enabling information interoperability are introduced and analyzed comprehensively based on related websites and literature. Furthermore, engineering information interoperability research supported by openBIM is analyzed from the perspectives of information representation, information query, information exchange, information extension, and information integration. Finally, research gaps and future directions are presented based on the analysis of existing research. The systematic analysis of the theory and practice of openBIM in this paper can provide support for its further research and application.
As its relatively large storage capacity and the ability of identifying and tracking materials and equipment in real-time without any direct contact or line-of-sight compared to traditional bar codes, Radio frequency identification (RFID) technology has been more and more adopted in many sectors and identified as one of the ten greatest contributory technologies of 21st century. To systematically shed light on potential applications of RFID for uninitiated readers, this paper first presents the principle and the brief history of RFID technology. Then the paper summarizes the RFID’s technical features which enable its popularity in industry. Finally, applications examples in construction industry are presented for highlighting its enabling employment. It is hoped that this paper will give a useful implications for RFID researchers and practitioners and provide a roadmap to guide future research
