Emerging building information modelling (BIM) can be complex to teach during a regular face-to-face class schedule, and even more challenging remotely or virtually. This has been further exacerbated by the outbreak of COVID-19 whereby the adoption of virtual teaching techniques in higher education has been strongly recommended. However, since the outbreak, in December 2019, there has been a paucity of research with regards to experiences with the virtual delivery of BIM. This study explores lessons learnt in engaging students through the virtual delivery of BIM courses during the COVID-19 pandemic. Quantitative data from a questionnaire and quantitative and qualitative data from the various module evaluation reports were used to inform this study. A main finding is that, despite being a technical course, BIM can still be delivered online without compromising any of its learning outcomes. In contrast to existing literature, the main contribution of this study is practical as it provides insights on methods that worked and those that can be used post-COVID-19 in delivering BIM courses. This study provides hope to prospective students, especially distance learning students, who often worry whether the technology aspects of BIM can be taught remotely. Although the study is grounded on BIM and driven by the COVID-19 context and distance learning, it has wider implications for learning and teaching in other technical disciplines and virtual learning in general. Specifically, the experiences and impacts of delivering BIM examined in this study can inform curricula design in other disciplines. Full article

When building homes, sustainability principles should be followed throughout the process to achieve maximum advantages. Building information modeling (BIM) activities can aid in achieving sustainable goals. Third-world countries’ building industry implements informal approaches to information dissemination through email newsletters and websites. This research seeks to provide a model for the application of BIM and its relationship with overall sustainable success (OSS) in building projects. BIM activities were identified from the literature, and a survey form was distributed to 180 professionals in the Egyptian construction industry. Partial Least Squares-Structural Equation Modeling (PLS-SEM) was used to establish the structure of BIM activities and assess their correlation with project success, revealing BIM accounts for 30% of sustainability. The study’s findings inform decision-making to improve project sustainability and reduce costs by introducing BIM to developing countries’ construction industries. Full article

The concept of sustainable urban design has appeared in different perspectives to minimize and reduce the negative impacts of urban expansion in terms of climatic and environmental drawbacks. One of the undeniable approaches of sustainable urban design is the adoption of green urban roofs. Green roofs are seen to have a substantial role in addressing and resolving environmental issues in the context of climate change. Research investigations have indicated that green roofs have a remarkable impact on decreasing rainwater runoff, reducing the heat island effect in urban spaces, and increasing biodiversity. Nevertheless, green roofs in urban spaces as a competent alternative to nature remains a standing question. To what extent can green roofs mimic the biodiversity that is seen in nature? Moreover, to what level is this approach practical for achieving a tangible reconnection with nature, or so-called biophilia? This study attempts to discuss the essence and impact of green roofs in urban spaces based on a case study approach. The study reflected lessons from the New York High Line Green Roof regarding biophilia and biodiversity in this case study. It concludes with key lessons that can be transferred to other urban spaces with similar settings. Full article

Post-conflict reconstruction has been one of the most challenging themes for the AEC industry, urban designers and planners, and related decision-makers, especially in complex urban contexts with severe destruction in terms of infrastructure. The city of Mosul in Iraq is a case where there is an urgent need for reconstruction, in particular the housing sector after the enormous destruction caused by the ISIS war of 2014–2017. Today, advanced technologies in construction present opportunities to address post-conflict reconstruction challenges. BIM has been used in recent years since it is an integrated and effective process for planning, monitoring and managing contemporary construction projects. Nevertheless, BIM has not been investigated properly in planning and managing post-conflict reconstruction, especially in developing countries. This paper discusses the potential of adopting BIM in post-conflict reconstruction through investigating the validity of the BIM process in planning and assessing possible housing solutions for the reconstruction of Mosul city, using BIM applications. The main findings suggest that BIM applications present significant potential in the process of planning, assessing and managing the reconstruction of post-conflict contexts in developing countries, where conventional methods are limited, dysfunctional and inefficient.

The urgent need to improve performance in the construction industry has led to the adoption of many innovative technologies. 3D laser scanners are amongst the leading technologies being used to capture and process assets or construction project data for use in various applications. Due to its nascent nature, many questions are still unanswered about 3D laser scanning, which in turn contribute to the slow adaptation of the technology. Some of these include the role of 3D laser scanners in capturing and processing raw construction project data. How accurate are the 3D laser scanner or point cloud data? How does laser scanning fit with other wider emerging technologies such as building information modeling (BIM)? This study adopts a proof-of-concept approach, which in addition to answering the aforementioned questions, illustrates the application of the technology in practice. The study finds that the quality of the data, commonly referred to as point cloud data, is still a major issue as it depends on the distance between the target object and 3D laser scanner’s station. Additionally, the quality of the data is still very dependent on data file sizes and the computational power of the processing machine. Lastly, the connection between laser scanning and BIM approaches is still weak as what can be done with a point cloud data model in a BIM environment is still very limited. The aforementioned findings reinforce existing views on the use of 3D laser scanners in capturing and processing construction project data. Full article
