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.

(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.
Government’s motives and investor’s commitment in public-private partnership procurement system adoption
(Sciendo, 2025) Amusan, Lekan; Ojelabi, Rapheal Abiodun; Adewolu, Adeoye Olugbenga; Olanipekun, Oladeji Olubunmi
The study examined the government’s motives - ment to infrastructure delivery. The study adopted a quan titative research method with a survey conducted using a structured questionnaire targeted at 384 respondents selected through random sampling. The data were ana lysed using mean, percentile and Pearson correlation sta tistical tools. The study identified 17 key motives respon sible for the government adopting PPP in socio-economic infrastructure delivery. These motives were factored into three main groups: public infrastructure maintenance, financial and economic benefits; improved discipline in the contractual relationship and predictable path in infra structure delivery and integration of innovative approach in enhancing infrastructure delivery. Therefore, the relationships between the three factored government’s motives and investor’s commitments, including finance, management, technical and operational services in PPP, were tested using the Pearson correlation statistical tool. The results showed that the motive for public infrastructure maintenance, financial and economic benefits of the government in PPP showed a significant relationship with the four services commitment of private partners. Also, the government’s motive for improved discipline in the contractual relationship and predictable path in infrastructure delivery showed significant relationships with technical, finance and management commit ments of investors. Lastly, the government’s motive for the integration of innovative approaches in enhancing infrastructure delivery showed a significant relationship with only technical commitment. The outcome indicates that factors measuring government motive and investor's services commitment are mutually dependent and critical in ensuring a sustained relationship among stakeholders in a PPP arrangement for infrastructure procurement.
Influence of Industry 4.0 Applications and Development of Internet of Things (IoT)-Based Logic Framework in Energy Management Systems in Buildings
(Praise Worthy Prize S.r.l., 2023) Amusan, Lekan; Aigbavboa, C. O.; Ebitimi, Vianana
– Energy management refers to the reduction of energy usage and costs with little steps like choosing LED light bulbs and energy-efficient appliances or larger efforts such as the improvement of insulation and weatherization. Energy management is simplified as foresighted, organized, and systemic production, distribution, and use of energy under ecological and economic target setting and judicious and effective use of energy to maximize profits and minimize energy demands. This work aims to develop a strategy for energy management in commercial buildings to create best-practice in commercial building energy consumption. Also, study the current energy practice in Nigeria and identify factors affecting energy management. A total population size of 150 comprises commercial buildings of malls and supermarkets where the Internet of Things (IoT) application was obtainable. Sample size of 100 comprised of respondents from the population was administered with 100 questionnaires out of which 80 valid questionnaires were used for the analysis. The questionnaire was administered among 13 branches of malls and mega supermarkets. That is an average of 6 questionnaires in each branch to respondents like managers, facility managers and other staff connected with the application of the installed IoT features. This study highlighted the factors that influence adequate and proper energy management in buildings. To this end, this research achieved the following objectives: To study the current practice of electrical energy management in commercial buildings, identify factors influencing electrical energy management in buildings (commercial buildings), and influence of Industry 4.0 applications in electrical energy management systems in buildings. The government should provide sufficient funding for power stations and maintenance activities. The use of Tariffing Meter System should be adopted in energy management, therefore eradicating the estimation billing system. There should be more aware of advanced networking and monitoring technologies for management.
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.
