    Issues with supply chain management documents that contribute to project delays
    (Department of Building Economics, 2024) Ekanayake, J; Allis, C; Jayasinghe, S; Lokuge, A; Sandanayake, YG; Waidyasekara, KGAS; Ranadewa, KATO; Chandanie, H
    Supply chain management is the process of obtaining the raw materials or components needed to create a product or service for an enterprise and deliver that product or service to customers. In construction, it is vital due to the involvement of a large number of resources and stakeholders. Hence, documentation plays a very important role in such a process. Yet, there are certain issues with supply chain management documents that contribute to the various issues of construction projects, including project delays. Hence, this research aimed to identify the potential factors affecting construction projects due to poor documents in supply chain management. This study was limited to building construction projects in Sri Lanka. Agreement errors of labour suppliers and material suppliers were the main areas of concern. In order to achieve the objectives of the research, semi-structured interviews were conducted among construction professionals such as site engineers, project managers, technical officers, and Quantity Surveyors. The results of the research revealed that the documents were not prepared correctly, which indirectly caused the project to be delayed. This could happen due to various causes, such as documentation errors that take a long time to be corrected, people are not aware of the documentation required in various stages of the supply chain, and the stakeholders are not aware of the procedures correctly for each of the scenarios. Findings further revealed that errors such as delays, arithmetic mistakes, and specification inaccuracies frequently disrupt operations. To address these issues, corrective actions tailored to each document type were detailed, emphasising early negotiation, skilled personnel involvement, and rigorous verification processes. The study contributes significantly to the field by offering practical solutions that enhance document accuracy, improve supply chain efficiency, and reduce project delays. These measures not only address immediate documentation issues but also provide a framework for maintaining high standards of documentation accuracy in the construction industry, ensuring smoother operations and successful project completions.

    Potential of virtual reality (VR) technology for safety training and accident prevention in construction
    (Department of Building Economics, 2024) Silva, M; Allis, C; De Silva, C; Sandanayake, YG; Waidyasekara, KGAS; Ranadewa, KATO; Chandanie, H
    The construction industry is inherently risky, with accidents and injuries posing significant challenges to workers' safety and well-being. Traditional safety training methods, while valuable, may have limitations in effectively preparing workers for the complex and hazardous environments they encounter. This study investigates the potential of virtual reality (VR) technology as an innovative approach to safety training and accident prevention in construction. Using a combination of literature review and empirical research, this study examines the effectiveness and feasibility of VR technology in simulating real-life construction scenarios, providing immersive training experiences, and enhancing workers' safety skills. The research explores the current state of VR adoption in safety training programs, identifies barriers to implementation, and proposes strategies for overcoming challenges. Qualitative design was used as the methodology and six industry experts were interviewed under semi-structured interviews. Key findings highlight the promising role of VR technology in improving safety awareness, hazard recognition, and emergency response among construction workers. Additionally, the study underscores the need for comprehensive training programs that integrate VR simulations with traditional methods to maximise effectiveness and engagement. Implications for practice include recommendations for safety training institutes, construction companies, and policymakers to invest in VR technology, develop tailored training modules, and foster a culture of safety consciousness within the industry. The study suggests avenues for future research to explore the long-term impact of VR training on accident rates, worker behaviour, and organisational safety culture. Overall, this research contributes to advancing safety practices in the construction industry by harnessing the potential of VR technology to prevent accidents, mitigate risks, and protect the well-being of workers.
