Purpose The purpose of this study is to develop a building information modelling (BIM)-based mixed reality (MR) application to enhance and facilitate the process of managing bridge inspection and maintenance works remotely from office. It aims to address the ineffective decision-making process on maintenance tasks from the conventional method which relies on documents and 2D drawings on visual inspection. This study targets two key issues: creating a BIM-based model for bridge inspection and maintenance; and developing this model in a MR platform based on Microsoft Hololens. Design/methodology/approach Literature review is conducted to determine the limitation of MR technology in the construction industry and identify the gaps of integration of BIM and MR for bridge inspection works. A new framework for a greater adoption of integrated BIM and Hololens is proposed. It consists of a bridge information model for inspection and a newly-developed Hololens application named “HoloBridge”. This application contains the functional modules that allow users to check and update the progress of inspection and maintenance. The application has been implemented for an existing bridge in South Korea as the case study. Findings The results from pilot implementation show that the inspection information management can be enhanced because the inspection database can be systematically captured, stored and managed through BIM-based models. The inspection information in MR environment has been improved in interpretation, visualization and visual interpretation of 3D models because of intuitively interactive in real-time simulation. Originality/value The proposed framework through “HoloBridge” application explores the potential of integrating BIM and MR technology by using Hololens. It provides new possibilities for remote inspection of bridge conditions.
Building Information Modelling (BIM), an emerging trend in the construction industry worldwide, has been officially introduced to Vietnam recently in some piloted projects. However, in Vietnam, the BIM market is still immature due to that the players in the construction industry have perceived many barriers in adopting this new solution. In a country with a civil law system like Vietnam, the legal environment is considered as the most important enabler for the construction industry to adopt innovative technologies, including BIM. This paper, using a hybrid research approach of surveys and expert judgment, discusses the most popular barriers in BIM adoption in the construction industry in Vietnam, which include five internal and five external barriers. The country’s BIM roadmap, policies and relevant legal documents that are currently in effective are then collected and analyzed in line with the discovered barriers in order to explore their effectiveness in creating an enabling environment for BIM adoption and implementation in the local conditions. After that, legal considerations on the clarity and feasibility roadmap for BIM adoption, the reasonableness of the strategy/plan to grow the industry’s BIM capacity, the system of relevant laws and regulations to govern the BIM-enabled construction projects, the need for a new set of standards and codes for BIM-related processes, and an incentive system for the pioneers in BIM adoption in public sector are discussed. Recommendations on the legal document system, governmental policies, incentives and supports from the Government to encourage the construction industry to apply BIM are then presented. Further research can be developed beyond this research to validate the research results in a broader coverage.
Building Information Modelling (BIM) has been proven as an innovative approach to bring values to construction projectsas well as stakeholders, including construction consultancy firms. BIM adoption could assist construction consultancy Small and Medium-sized Enterprise (SMEs) inenhancingtheir competitive capability. Using a case study with a pioneer BIM service providers whichis an SMEin Vietnam(the Consultant), the paper explores the core competences for deliveringBIM services in relation with potential competitive advantages. Fourtypical BIM market segments have been discovered, which include:i) BIM strategic services, (ii) BIM services, (iii) BIM-enabled services, and (iv) BIM tools development. Exploring six BIM cases, the realizedcore competences of the Consultant which are reported in the paper includethe BIM-related skillful human resources (both in-house and from external), BIM know-hows, reputation, and also the benefits from a BIM network that the Consultant established as an outcome of a granted BIM research project. Focusing on only the first three market segments, the Consultant has taken advantage of their core competences to deliver differentiation and focus strategies to compete and generate competitive advantages.Cost leadership strategies were not very successfulin the case study due to that the economies of scale could not be met; however, they can be considered withthe provisionof BIM-enabled services whenBIM services are delivered together with other consultancy and/or construction services.
