Item Restricted Impediments To Adopting Building Information Modeling In Saudi Arabian Infrastructure Projects(Texas A&M University, 2023) Alsofiani, Mohammed; Caffey, Stephen; Lewis, Michael; Dooley, Kim; Escamilla, EdelmiroThe present research investigates the impediments that hinder the infrastructure sector in the Kingdom of Saudi Arabia (KSA) from adopting innovative technological solutions that can enhance communication and collaboration, ultimately minimizing and preventing construction project delays. The focus is particularly on Building Information Modeling (BIM) and its role within KSA infrastructure projects. BIM serves as a pivotal technology in the Industry 4.0 era, facilitating data sharing among stakeholders throughout the lifecycle of built assets. However, the adoption of these technologies in KSA has encountered significant impediments. Thus, the current research aims to investigate the obstacles preventing the adoption of BIM in KSA infrastructure projects and suggests strategic approaches to overcome these hurdles. To accomplish the stated aim, the investigation process employs a combination of qualitative and quantitative research methods, including a systematic review and stakeholder surveys. Specifically, the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) protocol was utilized, and 149 AEC (Architecture, Engineering, and Construction) professionals from both the private and public sectors in KSA, who possess awareness of BIM technologies, participated in the survey. The results indicate that key impediments to adopting BIM include a lack of training and education, unclear business value, absence of adoption initiatives, limited demand from clients, resistance to change, a lack of standardization, and cost considerations. However, participants generally concur that the current communication and collaboration practices in the context of KSA infrastructure projects need improvement. To overcome the identified impediments, the research emphasizes the need for a BIM mandating strategy, which includes developing standards, guidelines, and regulations alongside promoting BIM education and training programs. Raising awareness among stakeholders through workshops and incentive programs is also crucial. This strategy should involve the active participation of governmental bodies and industry organizations with clear roles and responsibilities. By addressing the identified challenges and implementing the recommended strategies, infrastructure projects in KSA can benefit from BIM technologies to enhance the successful and efficient delivery of these projects.60 0Item Restricted Evaluating 4D Multiuser Construction Plan Reviews Using Augmented Reality(The Pennsylvania State University, 2023-08) Alghamdi, Saleh; Messner, JohnConstruction plan review meetings are valuable for stakeholders to discuss construction logistics and sequencing issues. Visualization is essential during these meetings and can significantly influence the outcomes. Construction plans can be visualized in 2D, 3D, or 4D environments where the time dimension is integrated with the 3D model elements. Means of visualization media differ and can take many forms, such as paper-based, screen-based, or immersive technologies. Immersive technologies add another level of interactivity that has yet to be thoroughly investigated in construction research. Collaboration is integral to construction plan review meetings, but limited research has focused on collaborative plan reviews that leverage immersive technologies such as visualization mediums. This research investigates the effects of immersive, multi-user Augmented Reality (AR) to support construction plan review meetings using 4D construction models. The study compares head-mounted AR to traditional screen-based 4D model reviews. A 4D Multiuser AR (4DMAR) application was developed to measure the effectiveness of AR as a review environment. A questionnaire was used to measure the participants’ overall experience and their preferences, along with observational data. Participants found the interaction in both environments easy while also perceiving that AR provided more options for interactivity. Participants also perceived the 4DMAR environment as more suitable for collaboratively reviewing 4D construction plans. Limitations included the limited scope of the 4D model and the selected sample's low experience level with AR and 4D modeling. Future work should consider adding more interactive features within AR applications and identify better methods to support the interoperability between 4D modeling software and AR platforms.9 0
