| Abstract: | 1. Background The concepts of 5D Building Information Modeling (5D-BIM)—which integrate 3D modeling with time and cost—have been extensively discussed in the field of Quantity Surveying (QS) to address contemporary management challenges in construction projects. However, the implementation of actual BIM systems for QS practices remains incomplete, and several practical issues have yet to be thoroughly examined. This research aims to bridge the gap between the theoretical perspectives on these issues and the real-world challenges faced, proposing solutions to overcome these practical problems. 2. Problem The implementation of BIM systems for QS works faces significant hurdles. Key issues include poor data accuracy, misalignment with industry measurement standards, resistance to organizational change and the absence of a cohesive contractual and legal framework for implementation. These factors impede the effective adoption of 5D-BIM in construction practices. 3. Findings of Previous Works Previous research (e.g. HKIS: 2013) has identified several practical problems that have hindered the effective use of 5D-BIM, including 1) Lack of detailed, accurate data in BIM models compromises the reliability of cost estimates; 2) Misalignment between BIM software and existing industry measurement standards, creating difficulties in itemisation of works and quantity take-off; 3) Absence of industry-wide norms and standards for 5D-BIM processes and deliverables; 4) Technical challenges in integrating comprehensive BIM models within tight pretender timelines; and 5) Organizational and cultural resistance to change among construction professionals and firms. Findings from previous research indicate that the effectiveness of 5D-BIM is closely linked to the level of training and expertise of the QS team. Firms with more experienced 5D-BIM personnel are better equipped to navigate the practical complexities and derive greater benefits from the technology. In recent years, training opportunities are abounded, particularly with the availability of the Construction Innovation and Technology Fund (“CITF”) in Hong Kong. Despite this, the use of BIM remains limited in the day-to-day practices of QS firms. 4. Proposed Aim and Objective This research seeks to address the disparity between theoretical perspectives and practical challenges. The reasons for such practical issues will be explored in this research. Whilst the Hong Kong Institute of Surveyors (“HKIS”) publishes a standard contract for BIM use, its use in practice is rarely heard. The reasons for such limited use will also be explored in this research. This research also explores whether project complexity and size influence the adoption of BIM and its associated benefits. It investigates whether larger and more complex projects tend to realize greater advantages from the enhanced cost management capabilities of 5D-BIM, while simpler, smaller projects may not justify the necessary investment. Through a case study, this research aims to capture and analyze the real-world challenges encountered during BIM implementation, examining not only organizational and conceptual aspects but also practical ones. The case study focuses on a small-scale residential project, discussing the effectiveness of BIM use for QS in this context. Additionally, the research delves into the concept of 'Contractual BIM' and the issues associated with it. Key concerns include the lack of clear contractual definitions regarding responsibilities and liabilities related to the BIM model, as well as questions surrounding data ownership and commercial sensitivity. 5. Proposed Methods To achieve these aims, this research will employ a mixed-methods approach, including: • Questionnaires: These will be used to gather quantitative data from industry professionals to identify the current status, problems, challenges, and future expectations regarding 5D-BIM. • Interviews: Qualitative insights will be collected from industry professionals with experience in BIM to understand their perspectives and experiences. • Case study: A small residential house project will be analyzed to illustrate the practical problems associated with using 5D-BIM in real-world scenarios. 6. Outcomes and Discussions This research offers a comprehensive examination of the real-life barriers and challenges associated with the implementation of 5D-BIM in Hong Kong's private sector. The findings underscore the need for a broad-based strategy to address the technical, organizational, and contractual issues that have impeded the wider adoption of this transformative technology. To fully realize the potential of 5D-BIM, the construction industry must collaborate to develop robust standards, revolutionize measurement rules and practices, provide practical training for both QS and BIM professionals, and encourage construction professionals to embrace new technologies. Additionally, it is essential to establish a clear contractual framework for using BIM systems to mitigate disputes and create a responsibility matrix. By tackling these practical challenges, the construction industry in Hong Kong can harness the benefits of 5D-BIM, leading to accurate cost estimates, efficient project scheduling, and improved overall project delivery. This, in turn, will help reduce risks, claims, and disputes. 7. Benefits and Contributions The insights derived from this research provide both strategic and practical value for industry professionals and researchers, facilitating the widespread implementation of 5D-BIM and its transformative impact on the construction industry. Specifically, the findings offer meaningful perspectives on the practical problems, challenges, and barriers to the adoption of 5D-BIM in Hong Kong's private sector, particularly from the viewpoint of QS. |
