【発表題目】「Investigating the current implementation of Employer’s Information Requirement in BIM-applied infrastructure projects in Vietnam（ベトナムにおけるBIMを適用したインフラプロジェクトを対象としたEIR実施状況の現況調査）」
【研究目的】
Building Information Modeling (BIM) offers significant benefits beyond visualization in construction project management. To leverage BIM effectively, employers must clearly define information requirements from the outset. These requirements, outlined in the Exchange Information Requirements (EIR), facilitate collaboration among stakeholders. However, determining the employer's EIR can be challenging due to organizational and social constraints, especially in early-stage BIM adoption countries such as Vietnam. This study aims to investigate specific issues with Vietnam employers' EIR provision through the analysis of bidding documents for BIM-applied projects. The analysis refers to the Center for Digital Built Britain's EIR guidance developed according to the principles of ISO 19650.
【研究内容】
The aim of this study is to investigate the current state of EIR provision in Vietnam. To achieve this, a four-step methodology is conducted, involving a literature review of EIR concept, framework selection for analysis, EIR document analysis, and identification of key issues.
Firstly, the review of EIR guidelines and previous studies identified three primary concepts of EIR, based on the British BIM standard PAS 1192, the international standard ISO 19650, and the ontology-based EIR concept (OntEIR). EIR outlined in ISO 19650 and the Center for Digital Built Britain's EIR guidance serve as the primary reference framework for this study.
Subsequently, the study collected 15 bidding documents for Vietnam BIM-applied projects on the Ministry of Planning and Investment's National Bidding Network System. EIR documents for Vietnam BIM-applied bidding packages are examined under each information requirement that corresponds to the three parts of the Center for Digital Built Britain's EIR guidance, including the information requirements and the project information standards, production methods, and procedures
After the analysis of EIR documents, the study indicates three key issues with employers' EIR provision for BIM projects in Vietnam. Firstly, employers do not fully consider Organizational Information Requirements (OIR), Asset Information Requirements (AIR), and Project Information Requirements (PIR) when defining EIRs. Secondly, EIRs for BIM projects in Vietnam lack specific requirements, particularly in terms of information containers, metadata naming, encoding, and classification rules, making it challenging to implement CDE alongside existing information sharing and approval processes. Lastly, the level of information development is not yet fully required in terms of the amount of information (data) contained/linked to the model (LOI). This has an impact on how employers assess the quality of the handover model.
【今後の展望】
Research into EIR formation is a foundation for effective BIM project management. Firstly, a strong emphasis on purposeful information procurement will play a pivotal role. In this context, the sequence of information requirements will be interconnected, with OIR serving as an input for AIR and/or PIR, while AIR and/or PIR in turn contribute to the EIR formation for each procurement package. A comprehensive consideration of OIR, AIR, and PIR in the EIR formation process will prevent unnecessary information requirements and necessitate a higher level of information development.
Moreover, developing standardized EIR templates for all projects will be challenging due to the interconnected nature of EIR, PIR, and/or AIR. Therefore, EIR template development should be categorized based on project types, such as civil engineering projects or transportation projects, or funding sources, such as ODA-funded projects, public investment projects, or PPP projects. This approach will ensure that developed EIR templates are more practical and easier to implement.
Additionally, specialized EIRs are required to accommodate international BIM projects involving parties with varying BIM capabilities and maturity levels. This necessitates close collaboration among project stakeholders to develop a unified set of EIR standards tailored to the specific needs of each project.
