A BIM-Based Value for Money Assessment in Public-Private Partnership: An Overall Review
Abstract
:1. Introduction
- (1)
- Relevant literature focused on PPP performances in order to summarise the most important indicators of procurement.
- (2)
- VfM content by summarising the guidance of both quantitative and qualitative assessments.
- (3)
- PPP policies and legal frameworks in different countries, as well as in-depth investigations from the published PPP project documents in China to indicate the VfM application status.
- (4)
- BIM-based research aligned with the VfM and other key performance indicators to further analyse the emerging operational framework.
2. Methodology
- Research Publications: The papers on PPP were mainly sourced from construction and public procurement domain journals using the ScienceDirect and Scopus search engines. The information was collected via systematic literature research using keywords and content criteria. The results revealed that the assessment indicators in VfM were aligned with the other key indicators, such as key performance indicators (KPI).
- Published Guidance and Documentation: This included the status of overseas VfM-related methodology published by the World Bank Group and procurement project documents in the Chinese financial sector. The documentation explained that VfM was inadequately catered for in current project practices. More specifically, procurement documentation from the Ministry of Finance of the People’s Republic of China was collected. The documents consisted of VfM reports on transportation, urban housing, education, culture, nursing, and municipal engineering from Chinese PPP demonstration projects, which heavily reflected the practical application of VfM.
- Procedures and Contents: Current representative legal VfM guidance was sourced from the related national and international governing bodies to express the requirements of VfM contents (e.g., British VfM assessment guidance, US Federal Highway Administration Guidebook for VfM assessment, and Chinese PPP VfM guidance). The selection of related guidance was gathered at various conferences and events, along with the information from literature and industry reports.
- Research Publications: The intersection of BIM and project quantitative and qualitative management aspects corresponding to the contents of the VfM were supplemented with transferable construction contents. A combined quantitative approach was taken to classify further and analyse the literature presented. In addition, the alignment between BIM and the ontological approach was also reviewed as a new research methodology for knowledgebase development.
- Tools and Software: The implementation of BIM for multiple project purposes corresponded to the VfM content.

3.3.1. VfM Qualitative Assessment
3.3.2. VfM Quantitative Assessment
- Qualitative assessment lacks an appropriate information query system, i.e., one able to support information queries and the position.
- The project data currently used for quantitative financial accounting are historical and may generate unreliable results. The information that could be acquired from multiple sources and resources is neither sourced nor represented, which brings about issues with the information exchange necessary for calculating the present values.

5. Discussion—Research Gaps Identified
- Information exchange—A scheme that highly accepted information delivery was lacking. Although there are various implementation approaches for calculating costs and quality features using an IFC model in the construction stages, no information exchange scheme was fully extended to encompass the significant elements of VfM within PPP infrastructure projects, especially in operation and maintenance stage. This is most likely due to the complexity of PPP, involving various types of infrastructure works. In addition, the growing use of big data approaches and machine-learning techniques are reducing the need for structured data formats. These emerging methods still require integrated datasets and explicit exchange requirements to capture the asset information in the very beginning and, later on, benefits the operation and maintenance [72,73,74,75]. Therefore, determining a universally agreed upon information exchange scheme is still a high-profile research area.
- Alignment of the VfM knowledge with the supporting information—There were numerous studies that used the BIM information and ontologies to automate various support solutions. These knowledge-based approaches have been applied to the PPP business domain at the organisation level, where BIM could benefit the project justification and procurement plans is an area yet to be explored and would be relevant to the various types of construction-based projects. VfM in PPP requires comprehensive qualitative and quantitative assessments. Due to the different types of procurements, VfM also requires knowledge support to facilitate a much more holistic process that considers determinants, especially the results of quantitative PSC and PPP values. These processes could be rendered much more effective.
- Data integration environment—BIM-based management systems have focused mainly on technical applications for integrating additional dimensions into the already developed 3D information model. The ability to analyse and visualise the data has only been determined within construction projects. However, even the IFC structure is expanding. The current datatype is difficult to use for project external data, such as financial and organisational data. The approach of placing all the project external data and internal data into a single database is urgently required, as this approach could be applied to real-world projects to provide more accurate results and create benefits in operation and maintenance. In such cases, the data extracted from BIM can guarantee the real-time accuracy of the internal project measurements. In addition, the linear or nonlinear data analysis approach could measure external performance. Therefore, a virtualised data integration engine should be explored to provide both one location for information and a database that contains project externalities.
6. Roadmap for BIM-based VfM in PPP
- The semantic environment has the potential to connect to the project information from a shared data environment. Information query and qualitative assessment could be facilitated by building up knowledge bases for different types of PPP projects.
- The information extracted from the BIM, which is a vital element of information initialisation, provides high-quality data input to guarantee the accuracy and high levels of synchronisation for the quantitative assessment. The PPP lifecycle project flow is considered, and the BIM enhances the information exchange.
