    Exploring the Integration of Digital Technologies and Lean Principles for Transformative Construction Project Management: A Review
    (The Fourteenth International Conference on Construction in the 21st Century, 2024-09) Adewale, B. A.; Aigbavboa, Clinton Ohis; Ogunbayo, B. F.; Ene, Vincent Onyedikachi
    This study explores the synergies between digital technologies and lean project delivery to address persistent challenges in the construction industry. The primary aim is to examine the integration of digital technologies, such as Building Information Modelling (BIM) and modular construction techniques, with lean principles to transform construction project management. Building on previous research highlighting the potential of these approaches, a narrative literature review examined existing knowledge on leveraging digital tools to enable lean project delivery. The review process involved secondary data from scientific databases, with 150 potentially relevant papers scrutinized and reduced to a final sample of 68. Findings demonstrate that integrating digital technology and lean principles drives substantial improvements in collaboration, visualization, data-driven decision-making, productivity, supply chain management, and overall project performance, as evidenced by global case studies. The study identified key challenges and implementation considerations, including the need for cultural shifts, training investments, and robust data management capabilities. BIM's role in enhancing design coordination and modular construction's contribution to waste reduction and efficiency are highlighted as critical components of this integrated approach. The research builds upon earlier studies emphasizing the importance of digital transformation in construction, while uniquely focusing on its synergies with lean principles. Future research directions include in depth case studies, empirical investigations, and collaborative initiatives to further validate benefits, develop best practices, and explore emerging technologies' role in enhancing digital-lean synergies, thus unlocking the full potential of this integrated approach.

    Assessing Building Information Modelling Usage Level in Construction Projects: Construction Professionals Perspectives
    (The Fourteenth International Conference on Construction in the 21st Century, 2024-09) Ogunbayo, B. F.; Aigbavboa, Clinton; Liphadzi, Murendeni; Adewale, B. A.
    Building Information Modelling (BIM) usage in the construction industry has rapidly become a game-changer in construction activities, which has revolutionised project planning, designing, construction and management, leading to significant improvements in project coordination, collaboration, efficiency, and overall project outcomes. Hence, this study aims to assess BIM usage in construction projects based on construction professionals' perspectives toward establishing its usage level for different construction activities. Structured questionnaires were distributed to construction professionals in Gauteng province, South Africa, using systematic random sampling techniques to collect data on the level of BIM usage for construction activities for projects within the construction industry. Data was collected through the quantitative approach using a questionnaire survey. A valid mean item score was determined in the study using a statistical data equation; each item was ranked with standard deviations, and Cronbach’s alpha was established. The study findings indicated that project design and planning were the highest-ranked levels of BIM usage in projects in the construction industry. The study recommends that evolving BIM with other innovative technologies, such as cloud-based collaboration, digital twins, and artificial intelligence, will drive the digital transformation of construction projects, improve project delivery processes, and create value for construction stakeholders. The study concluded that the continuous usage of BIM for construction activities will play a key role in reshaping the future of activities in projects and driving digital transformation within the construction industry.
