Lessons learned from the impact of COVID-19 on the global construction industry

Abstract: Purpose: The construction industry represents most of every country’s finances and vital to continued economic growth and activities, especially in developing countries. The impact of the severe acute respiratory syndrome-2 disease (COVID19) on the government’s income resulted in the expectation of many public projects being cancelled or delayed providing little opportunity for the emergence of new public projects. This study collated a global qualitative perspective (survey interviews) on the lessons learned during the COVID-19 pandemic and the positive and negative impacts for future-proofing the construction sector. Design/methodology/approach: In total, 76 respondents from five continents excluding South America responded to the online open-ended structured questionnaire. Data collected were analysed through artificial inteligence analytics tool – Zoho analytics. Findings: The themes indicating the positive impact obtained from the interview were overhead cost reduction, remote working environment, focus on health and safety, improved productivity and sustainability goals while the themes signifying the negative impact were low business turnover, delays in construction payment and output, difficulties working from home and job losses. Supply chain management, construction project management improvement, concentration on health and safety and effective virtual working environment were collated as themes on lessons learned. Social implications: The major findings of this study emphasise on the need to improve the occupational health and safety and onsite safety measures for future proofing of the construction industry. Originality/value: The findings from the analyses made clear the imperativeness of the built environment research, with a focus on novel framework and strategies for future proofing the construction industry. © 2021, Emerald Publishing Limited.

Diffusion of innovations: the status of building information modelling uptake in Nigeria.

Abstract: 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 595% are aware of BIM technology; 228% are aware and currently using BIM and the remaining 177% 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

Comparative analysis of BIM adoption efforts by developed countries as precedent for new adopter countries.

Abstract: Building information modelling (BIM) adoption is generally assessed through one of two main approaches: 1) statistical evaluation of survey responses from stakeholders operating within a country or market, and 2) the use of macro BIM-adoption models and metrics. The recent paper "Macro-BIM adoption: comparative market analysis" sets the pace for continuous development of comparative market studies. However, precedent is important for continuous learning and adoption to contextualise this evolving field. This study aimed to set a unique precedent throguh comparative analysis of BIM adoption trends in the USA, UK and Australia, in order to set the pace for beginners or early BIM-adopting countries. This study is literature-based, analysed using content analysis. The study revealed the following: 1) A vibrant and evenly-distributed BIM adoption requires government involvement; 2) A government mandate facilitates wide BIM adoption and integrates a country's industry into the wider world; 3) A mandate also facilitates BIM research and training, which lead to a rise in the country's income through providing training and workforce export; 4) The dynamic of diffusion vary at different times, depending on a country's flexibility towards adoption of innovation; 5) The dynamic also changes as the industry's culture and regulation changes. Recommendations are made based on the study findings, especially with regards to the new adopter countries planning to develop a strategy for macro-BIM adoption.

Causes of building failure and collapse in Nigeria: professionals' view.

Abstract: Shelter or housing is the first thing humans need for living in this world even before food. The construction sector is the provider of physical infrastructure essential for human sustenance and economic development. Moreover, the advancement in vertical city expansion is enormous and to be celebrated; however in Nigeria, such development comes with huge human and material losses. For over three decades, Nigeria has been experiencing collapse of multi-story buildings. To investigate this phenomenon, primary data were collected through a questionnaire survey from professional construction consultants, contractors and clients. 150 structured questionnaires were randomly distributed of which 99 number were successfully retrieved for analysis. The 99 number questionnaires were analysed using simple statistics and charts. The result reveals that the frequency of building collapse in Nigeria is at an alarming rate and the impact is moderately major; substandard reinforcement, structural steel and cement used for the production of foundations, columns, beams and slabs are the main causes of building collapse (in descending order). While all these are associated with lapses in construction supervision with a relative importance index (RII) of 0.812 (ranked 1st) followed by construction process with RII of 0.709. Professions / professionals linked to the problems were also examined and recommendations are made based on the findings of the research.

The Nigerian Pharmaceutical Supply Chain: Blockchain Adoption, Counterfeit Drugs and Successful Deployment of COVID-19 Vaccine in Nigeria

Abstract: Aim: Critically investigating the possibility of adopting blockchain technology within the Nigerian pharmaceutical supply chain to curb the supply of counterfeit drugs. Study Design: The study is qualitative in nature and the primary data were fetched through interviews. Place and Duration of the Study: Conducted within Nigeria for a period of 3 months. Methodology: A qualitative method of data collection was adopted in the study, where some stakeholders were interviewed. The interviews were conducted with employees from different pharmaceutical companies and some drug regulatory agencies in Nigeria. Original Research Article Labaran and Hamma-Adama; JSRR, 27(2): 20-36, 2021; Article no.JSRR.66512 21 Result: Firstly, this study has ascertained the current prevalence of counterfeit drugs and the reasons for that. The study discovers a very high level of counterfeit drugs and some reasons behind that. Secondly, this study has also found some barriers to blockchain adoption, including the fact that the level of awareness of blockchain technology among stakeholders within the Nigerian pharmaceutical supply chain and the regulatory agencies is very low. Conclusion: It was concluded that the efforts put in developing a viable COVID-19 vaccine could be undermined due to the current nature of the Nigerian pharmaceutical supply chain, the nature of porous borders in place, absence of an apparent drug distribution system, among others. This study also concludes that the supply chain's current structure needs more regulatory and structural interventions by the Nigerian government than blockchain technology. In other words, with the current nature of the supply chain, blockchain technology adoption would not be effective in delivering the said benefits reported by scholars because the atmosphere is not conducive for successful blockchain adoption.

Investigating the barriers to building information modeling (BIM) implementation within the Nigerian construction industry

Abstract: The purpose of this paper is to identify and assess the perceptions of constructional professionals on barriers to implementation of building information modeling (BIM) within the Nigerian construction industry.,A scoping literature review was conducted to identify the fourteen barriers to implementation of BIM, which were employed to design a questionnaire survey. Data collected were analyzed using descriptive statistics, mean score, Kruskal–Wallis test, analysis of variance and multivariate techniques such as factor analysis.,The descriptive and empirical analysis demonstrated a disparity of ranking of the 14 barriers factors among the groups; however no statistically significant differences among the 14 barriers to BIM. Based on the mean score ranking results, only three (out of 14) barriers are identified as critical (mean score greater than 3.5): few studies available on BIM and lack of knowledge, inexistence or inadequate government policies, and high cost of implementation. The results of the one-sample t-tests show that they were statistically significant differences in 10 out of 14 barriers as follows: few studies available on BIM and lack of knowledge, lack of demand for use and acceptance of BIM, inadequate contractual coordination, lack of specified standards, cost of data and information sharing, technological availability issues, reluctance of other stakeholders, business and cultural changes, data and intellectual property issues, and interoperability issues. The study, through factor analysis, categorized the fourteen barriers to BIM implementation into four principal factors. The factors are: technology and business-related barriers; training and people-related barriers; cost and standards-related barriers; and process and economic-related barriers.,The identification and assessment of the key barriers to BIM implementation would be useful for the construction professionals and other stakeholder of the construction industry with the view to advance BIM adoption in Nigeria. This could also be extended to other developing countries through considerations of the local economic conditions, given the status of BIM as being in the germinating stage of development in Africa.,The study provides insights on the barriers to BIM implementation across the Nigerian construction sector environments. The innovative aspect of the study is the identification of the ordered and grouped (composite) set of barriers to BIM which could be used to developing appropriate mitigating solutions.
