Research on 'digitalization and collaboration' in the construction industry has been gaining momentum in the recent academic engagements. Despite its existence in many industries (i.e. financial services, retailing, publishing and travelling) for over ten years, it is yet to catch up by the construction market; this is due to several challenges whose existence are more dynamic and contextual than generic to various countries. The problems are defined in many studies across borders, but their impacts varied with countries. This case is equally the same to drivers toward the adoption of BIM. This study analyses barriers and drivers to BIM adoption in the Nigerian construction industry from adopters and non-adopters perspectives as to allow an informed decision in developing a strategy for macro BIM adoption. Primary data fetched from professional stakeholders through an online questionnaire survey were analysed using SPSS software and Microsoft Excel. This investigation reveals the most significant barriers against BIM adoption as Lack of expertise, Lack of standardization and protocols to mention but a few. And, most influential drivers from both adopters and non-adopters as Availability of trained professionals to handle the tools, Proof of cost savings by its adoption, BIM Software affordability, and awareness of the technology among the industry stakeholders. The adopters and non-adopters groups have nearly equal Percentage Disagreement (PD) and Percentage Agreement (PA) for both the barriers and drivers to BIM adoption. Thus, this suggests that the adopters are still at the early stage of BIM adoption, so have nearly the same perceptions with the non-adopters. The study recommends proper consideration of the established barriers and drivers while developing any strategy for effective BIM adoption. Further face-to-face (interview) study is necessary to explore more and in-depth challenges to adoption of BIM in the industry; and as the industry is getting more aware of the BIM, periodic evaluation of the critical barriers and drivers is vital.

Aim: This study evaluated Building Information Modelling (BIM) awareness and adoption in Nigeria through the line of enquiry known as the ‘diffusion of innovations’ and its possible uptake. Study Design: The study is quantitative in nature and the primary data fetched through questionnaire survey within Nigerian construction industry. Place and Duration of the Study: Conducted within North-west, North-central and Lagos, Nigeria for a period of 4 months. Methodology: A quantitative approach was adopted to x-ray the Nigerian construction industry; a structured questionnaire was used across the Architecture, Engineering and Construction (AEC). The generated data were analysed through descriptive statistics (in percentages) and presented in charts and graphs. Results: The result revealed that 59.5% are aware of BIM technology; 22.8% are aware and currently using BIM and the remaining 17.7% neither aware nor using BIM; consequently, the industry was evaluated just within the Late Majority in terms of awareness and just entered the Early Majority in terms of BIM technology adoption. Conclusion: Nigeria is at least five years behind US, UK and South Africa. In addition to lagging behind by at least five years, it is also behind by about 10% and 50% for UK and US respectively. The study also discovers the most significant barriers to BIM adoption as lack of BIM experts and lack of collaboration by its team stakeholders. The industry is likely to take the UK pattern in adopting the BIM and Recommendations are made based on the findings of the research.

Flooding is one of the most frequent and destructive natural disasters worldwide, with intensifying socioeconomic and environmental consequences linked to rapid urbanisation and climate change. This review examines flood risk delineation and assessment in Nigeria within a broader Global South perspective, synthesising evidence from peer-reviewed studies that employ remote sensing, GIS-based techniques, and multi-criteria decision analysis. The analysis reveals persistent challenges that undermine effective flood risk management, including incompatible datasets, limited stakeholder participation, and inadequate integration with formal planning systems. To address these gaps, the study introduces the GIS-Integrated Flood Risk Management (GIFRM) Framework, a conceptual model that integrates high-resolution risk mapping, adaptive infrastructure design, sustainable urban planning, and participatory governance. GIFRM advances resilience discourse beyond hazard mapping, offering a practical bridge between science, policy, and implementation by aligning technical geospatial analysis with actionable planning solutions. Comparative case insights from flood-prone countries such as Bangladesh, India, and Kenya highlight transferable strategies, including community-led data integration, modular infrastructure approaches, and localised zoning reforms. The review concludes by critically examining the operational disconnect between advanced geospatial risk assessment and its application in resource-limited, rapidly urbanising settings. It reframes flood risk assessment as an interdisciplinary planning tool with global relevance, delivering lessons for disaster preparedness, urban sustainability, and climate resilience. In the face of escalating hydrometeorological extremes, this research offers applied strategies for embedding GIS technologies into adaptive policy frameworks, positioning flood risk management as a core driver of sustainable development.

Effective collaboration and maximum effort from stakeholders during the feasibility and concept design stages in architecture provide the greatest potential for added value for the overall success of a building project, from the initial design through to construction and operation. What is more, design processes within different disciplines have been extensively mapped and they provide a valuable insight for managing the information between different conceptual stages. Based on that information, a pre-defined conceptual design protocol is established, tested and compared to the current paradigm of conceptual design. The aim of such a protocol is to enhance the conceptual design activities by guiding the multidisciplinary design team through the conceptual stage, highlight the importance of that stage and, eventually, provide the maximum information that will feed into later and more advanced design stages, aided by tangible user interfaces (TUIs) mediated collaboration. The initial results of the research are showcased and further research potentials are pointed out

This paper explores drawing as a design medium for conceptualising ideas within the built environment professionals and its application through computer mediated environments and tangible interfaces in particular. Developments in human-computer interactions' technologies allow the integration of physical and digital realms. Furthermore, advances in multi-touch displays promote the hap tic experience, which is substantial for externalising and communicating visual ideas among designers. As a result, an interactive surface is tested in two different studies with a multidisciplinary group of built environment professionals. The aim of the paper is to compare two different design applications, a commercial available one and a tailor-made one, to further analyse the effect of such an environment on the participants' perceptual, conceptual and collaborative actions and, eventually, to propose further research on augmented design platforms.
