Asymmetry in Professionals’ Perceptions of Sustainable Construction
(2022) Tunji-Olayeni, Patience; Aigbavboa, Clinton; Oke, Ayodej
Sustainable construction is the response of the construction industry to the environ mental, social and economic challenges arising from construction activities. Although the negative impact of construction activities is a global problem, it has local effe cts that require the inputs of indigenous stakeholders for mitigation. Hence, the study assessed the perceptions of professionals about sustainable construction with a view to boosting understanding of how individual awareness and commitments influence the implementation of sustainable construction. The study adopted a quanti tative research approach to obtain information from professionals working in different sectors of the construction industry in Lagos, Nigeria. Descriptive and inferential statistics were used to analyse data from the survey. Findings revealed statistically significant differences in the perceptions of professionals about sustainable constri ction. The findings have implications for: the design of sustainable construction policies, the business case for sustainable construction and the diffusion of sustainable construction.
Construction 4.0 Application: Industry 4.0, Internet of Things and Lean Construction Tools’ Application in Quality Management System of Residential Building Projects
(MDPI, Basel, Switzerland., 2022) Amusan, Lekan; Aigbavboa, Clinton; Essien, Stella; Emetere, Moses; Obaju, Biodun
The advent of Construction 4.0 has played a major role in construction industry develop ment through the improvement of quality performance. One of the parameters that have contributed immensely to the management of construction quality in the industrial revolution era is Industry 4.0, the Internet of Things (IoT), and Lean thinking concepts. Lean construction is characterized by a set of clear objectives in project delivery involving the concurrent design of products and processes. The study aims to carry out an exploratory study of the application of Construction 4.0 and Industrial 4.0 in quality management of building works and the development of Lean-based quality management models: The study engaged a survey design approach, and a random sampling technique was used to select the study samples. A structured questionnaire designed on a Likert scale 1–5 was used to collate data on the quality aspect of a construction project, and the data were used in model creation. The parameters that emerged are cast as the quality management model. The resultant factors were categorized into three (3) quality categories, which are the Zero level Defect range, Medium Quality, and High-Level Quality Range. The three (3) quality factors were recommended for adoption for quality management of residential building projects.
Critical Success Factors for the diffusion of Artificial Intelligence in the Nigerian Construction Industry
(AHFE Open Access, 2022) Tunji-Olayeni, Patience; Oke, Ayodeji Emmanuel; Aigbavboa, Clinton
Adopting Artificial Intelligence (AI) in the construction industry can improve constru ction processes, enhance competitiveness and boost the overall performance of the industry. However, the use of AI in the construction industry particularly in develo ping countries such as Nigeria is limited. This study examined the critical success factors for the diffusion of AI in the Nigerian construction industry. The study ado pted a quantitative research design with the use of questionnaire to elicit information from construction professionals in Lagos Island, Lagos, Nigeria. The study showed that institutional factors, behavioural factors and cost factors were the most critical success factors for the diffusion of AI in the Nigerian construction. Other factors inclu ded knowledge factors, infrastructure factors, technical factors and trust factors. The study offers some insights into the critical success factors for the diffusion of AI in a developing country such as Nigeria.
Disruptive industry4.0 intervention and economy security strategy for supporting construction business in the COVID-19 pandemic era
(Emerald Publishing Limited, 2023) Amusan, Lekan; Aigbavboa, Clinton; Amotsuka, Gift Apugha
This research looked into disruptive industry4.0 intervention and economic security strategy for supporting construction business during the COVID-19 pandemic, influence of the COVID-19 pandemic on materials, human resources, and building project completion time in Rivers State, Nigeria. This study aims at identifying result oriented strategy that could help to avoiding cost and time over-run on construction site during post COVID-19 pandemic era. For this research work, 100 questionnaires were administered. The influence, effect, and strategies adopted throughout the management and control of construction work during the COVID-19 pandemic, as well as health and safety protocols in use on construction sites during the COVID-19 pandemic, were all areas identified in the questionnaires that were administered as a primary source of data, the relative agreement index, and SPSS were used as secondary sources of data to supplement the questionnaires' results. The COVID-19 pandemic had an influence on several construction companies in Rivers state, from material logistics to material use, wages and salaries of workers were also affected, and the health and safety protocols put in place on-site by management were highly mandatory for workers to prevent the virus from spreading. In addition, the development of COVID-19 pandemic awareness programs was the most widely accepted tactic implemented by construction company executives in Rivers state. Construction businesses should provide transportation for construction workers, regular health assessments, COVID-19 palliatives, pre-time payment of earnings and salary, and source reputable material suppliers, according to the recommendations derived from this research work. Disruptions that need to be implemented in construction businesses are using a digitalized work environment to help construction businesses to continue even during the pandemic (BIM & machines), Government also helping construction businesses by providing incentives and direct public investments and Identifying of opportunities to shift work offsite.
Gender‑Based Challenges in the Construction: Industry Perceptions from Two Generations
(Taylor and Francis, London, 2024) Tunji-Olayeni, Patience; Aigbavboa, Clinton; Oke, Ayodeji; Ogunade, Toluwanimi
Influence of Industry 4.0 Applications on Covid-19 Pandemic in Managing Materials, Human Resources and Completion Time of Construction Projects
(Praise Worthy Prize S.r.l., 2024) Amusan, Lekan; Odusola, Mojisola; Aigbavboa, Clinton; Ajao, Ayodele Christianah
This research was centered on the influence of Industry4.0 in effective management of Covid-19 pandemic on construction sites and materials and resources of construction projects on construction sites. This study aims to increase sensitization about the COVID-19 pandemic's influence on the construction industry. For this research work, 80 questionnaires were administered to selected construction sites in the areas with highest incidence of Covid-19 in South Western Nigeria (Lagos State). The influence, effect, and strategies adopted using Industry4.0 apparatus The structured questionaire designed in Likert scale was distributed to respondents. The collated questionaire was test for validity and reliability and was found to be in good order. Spearman ranking, ANOVA, Mean item scores and relative agreement tools were used to process the data.It was discovered that Industry 4.0 tools were of good help during the pandemic in allocation, distribution and curation of information and resources. It was also discovered that COVID 19 posed a lot of challenges in administering human resources personnel while companies suffered procurement of effective human resources, low productivity and casualties while the pandemic lasts. The study however recommended intense use of the Industry4.0 tools in construction process administration even in the advent of Zero Covid 19 incidence on sites.
