Adoption and Barriers of Engineered Bamboo Products in the Nigerian Construction Industry
(Civil Engineering and Architecture 13(2), 2025) Ojelabi, Rapheal A.; Omuh, Ignatius O.; Amusan, Lekan M; Ogunrinde, Olugbenro
The rise in the cost of conventional construction materials and the greenhouse effect from construction activities have been an issue of concern to stakeholders in the construction industry. Hence, efforts have been concentrated on developing low-cost, environmentally friendly and sustainable local materials to mitigate the greenhouse effect. The quest for the sustainable materials necessitates the study to examine the prospects of adoption of engineered bamboo products and the challenges militating against its use among construction professionals. A quantitative approach was adopted and 70 questionnaires were distributed among construction professionals with structural engineering background in selected firms across Lagos State. Data collected were processed using percentage, mean item score and Kruskal Wallis’s test. Facts garnered from the study revealed that engineered bamboo adoption for construction related works like ceiling, flooring, and reinforcement among others is not outstanding. The poor implementation of the engineered bamboo products is attributed to some challenges which include ‘high affinity for conventional materials’, ‘unavailability of bamboo products’ and ‘lack of machinery to refine raw bamboo’ among others. Therefore, the study recommends that stakeholders need to channel more resources into research and development and creating an enabling policy that can enhance the bamboo products adoption.

The uniqueness and inherent complexities of the construction industry require the use of Artificial Intelligence (AI) to improve its processes and enhance overall competitiveness and performance. This study examined the awareness level and application of AI to provide useful insights into the state of AI applications in the Nigerian construction industry. A quantitative research design with the use of a questionnaire was used to obtain data from 53 construction professionals in the Lagos Island area of Lagos State, Nigeria. The professionals included Quantity Surveyors, Architects, Civil Engineers, Builders, and Estate Surveyors selected based on a purposive sampling technique. Data from the survey were analyzed with frequencies, mean, and ANOVA. The study found that most of the respondents were aware of the application of AI in construction, and there was no difference in the awareness level of the participants irrespective of their professional affiliations, organizational type, and organizational size. Generally, the most common application of AI among the participants surveyed were generative designs in BIM, measurement and estimating software, and the use of sensors in intelligent buildings. Moreover, design and project planning was found to be the most critical areas of need for AI in the study area. The study underscores the need for investments in other AI applications other than BIM and estimating software to improve productivity, performance, and enhance client satisfaction.

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.
Barriers Hindering Green Building Materials Adoption in the Nigerian Construction Industry
(Ingenta Connect, 2024) Tunji-Olayeni, Patience; David, S.
The adoption of green building material can lower greenhouse gas emissions emanating from construction related activities. Green building materials (GBM) have a lower carbon footprint, it has more energy efficient and also offer better thermal comfort which make them advantageous than conventional building materials. Green Building material (GBM) offers environmental, social and economic benefits over conventional building material. However little empirical evidence exists of the wide spread adoption of GBM at scale in especially in developing countries, particularly Nigeria, what could be the factor that hindered GBM adoption. To answer this, this paper assesses the barrier hindering GBM adoption in Nigeria construction industrial (NCI). It uses a cross-sectional survey research design with a structured questionnaire to achieve the aim of the study. Inferential and descriptive statistics were used to analyse the data gotten from the survey. The result from the analysis showed; lack of government policies focused on Green building materials adoption, lack of knowledge about Green building materials, lack of industrialized systems for Green building materials production, Lack of institution to formulate policies and set guideline and Lack of Demand for GBM are the first five main barriers hindering GBM adoption in Nigeria. The findings of the study have great implications for GBM policy, design and implementation. These Policies will serves as frameworks which can create an enabling environment for GBM production to thrive and also drive the adoption of the same in the NCI. Ultimately this will cut down on greenhouse gas emissions and mitigate climate change.

(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.

(Routledge; Taylor & Francis, 2026) Tunji-Olayeni, Patience; Adah, Christiana Ada; Daniel, Emmanuel Itodo; Aghimien, Douglas
The construction industry is facing a shortage of skilled workers worldwide. This shortfall can be addressed through the construction craftspeople apprenticeship system, which has not received significant attention in developing countries like Nigeria. This study aims to explore the experiences of apprentices in construction craftspeople apprenticeship programs in Nigeria. Data were collected using questionnaire surveys and interviews. Astructured questionnaire was distributed to thirty-two apprentices across two construction craftspeople apprentice ship programs in Nigeria, and sixteen interviews were conducted. The survey data were analyzed using the Relative Importance Index (RII), while data from the interview were analyzed using content analysis to identify key themes. The findings revealed that the primary motivators for individuals to pursue apprenticeships in the construction sector include the desire to work in the construction industry, the opportunity for skills and ability development, and the opportunity for income and associated benefits. Conversely, the major challenges faced by apprentices include limited job availability after completing their apprentice ship, poor or nonpayment of allowances, redundancy during training and inadequate training quality. These findings are significant for con struction stakeholders as they highlight the need for strategies to encourage young people to engage in apprenticeship training while addressing the challenges faced by apprentices.

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.
Diagnosing Government Responsibilities in the Implementation of Public-Private Partnership System for Infrastructure Procurement
(International Journal of Sustainable Development and Planning Vol. 20, No. 6, 2025-06) Ojelabi, Rapheal A.; Oyenubi, Adebayo; Oyeyipo, Opeyemi
Public-Private Procurement is a system that allows for collaboration between the government and private partners in infrastructure provision. However, researchers argued that the successful implementation of the procurement option rested more on the government's shoulders. Hence, the study aims to identify critical government roles and investigate their importance and performance in PPP projects in Nigeria using a survey approach. The targeted respondents are PPP stakeholders operating in Lagos and Abuja. However, due to the absence of comprehensive lists of the PPP stakeholders involved in PPP projects in Nigeria, a project based approach was used in attaining the representative samples for the study, including contractors, consultants, concessionaires, government agencies, and financiers. About 384 copies of questionnaires were randomly distributed to the sample representatives, and 274 copies were retrieved. The data generated were analyzed using descriptive and inferential statistical tools. Findings showed that all the roles identified are critical and showed significant interrelationships with each other. However, the government's performance in the highlighted roles is unsatisfactory, and recommendations were made on its shortfall.

(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.
Evaluating Construction Project Performance: A Case of Construction SMEs in Lagos, Nigeria
(IBIMA Publishing, 2016) Tunji-Olayeni, Patience; Mosaku, Timothy Olusoji; Fagbenle, Olabosipo Ishola; Omuh, Ignatius Owoicho; Joshua, Opeyemi
Performance evaluation is a vital tool for assessing management performance and formulating corporate strategies. The Nigerian construction industry is reported to be very vibrant and one of the largest in Africa. It is made up of 78% indigenous firms and 22% foreign firms. The indigenous firms are predominately small and medium – sized. However, the Nigerian construction industry have been challenged to improve its performance because of reports of performance problems in terms of cost over runs, time over runs, poor quality of work, low productivity among other problems. The aim of the study was to establish the measures used by construction SMEs for evaluating performance. The study employed a case study research design. Five construction SMEs in Lagos, Nigeria were selected as case studies. The findings revealed that construction SMEs do not use any of the established performance measurement frameworks for evaluating performance. The main performance measures used by construction SMEs are cost, time, quality, customer satisfaction, profitability of the project, labour productivity, safety and team work. It was also established from the study that construction SMEs do not use supply chain management and employee satisfaction. It was suggested that construction SMEs should also use supply chain management and employee satisfaction because these measures have been found to impact positively on firms’ performance.

Exploring the Cyber Technology Critical Success Factors for Sustainable Building Projects:
(MDPI, Basel, Switzerland, 2022) Tunji-Olayeni, Patience; Oke, Ayodeji Emmanuel; Kineber, Ahmed Farouk; Ekundayo, Damilola; Edwards, David J.
We sought to identify and examine the critical success factors (CSFs) necessary for incor porating cyber technology into residential building projects to augment operational performance and sustainability. An iterative two-stage approach was adopted to explore the phenomena under investigation. General CSFs for cyber technology were first identified from the extant literature, and subsequently explored using primary questionnaire survey data accrued from professionals within the Nigerian building industry. The survey results illustrated that the availability of sensors, good communication networks, mobile devices, and device layers and the creation of workable virtual modes are the main critical success factors for adopting cyber technology. Moreover, Gini’s mean difference measure of dispersion showed that the success factor in stationary cyber technology adoption is government support. The study’s findings guide building industry stakeholders to embrace cyber technology to improve cost and sustainability performance in the Nigerian building industry. Due to the originality of the findings of this study, a strong basis is provided for critically evaluating and analyzing the many vital aspects of cyber technology success.
Factors influencing the intention to adopt green construction: an application of the theory of planned behaviour
(Emerald Publishing Limited, 2023) Tunji-Olayeni, Patience; Kajimo-Shakantu, Kahilu; Ayodele, Timothy Oluwafemi
Purpose – The aim of this paper is to assess the behavioural factors that influence professionals’ intention to adopt green construction based on the theory of planned behaviour (TPB). Design/methodology/approach – The study adopted a quantitative research design with the use of online questionnaires to elicit information from construction professionals in South Africa. Descriptive statistics of frequencies, mean and standard deviation were used to analyse the data obtained from the survey. Linear regression was also used to assess the effect of behavioural factors on professionals’ intention to adopt green construction. Findings – The results showed that attitude and perceived behavioural control (PBC) have a significant effect on the intention to adopt green construction. These were significant at p < 0.05, having p-values of 0.000 and 0.015 respectively. The study also found that there was a positive disposition towards green construction, particularly with regards to insisting on green construction. This had a mean value of 3.99. There was also a high perception of succeeding in the execution of green projects with mean score of 3.76. Practical implications – The practical implication of the findings is that adoption of green construction in South Africa is majorly based on the positive attitude of stakeholders towards green construction and also the PBC or the perceived ease of executing green construction. However, these factors are not sufficient to generate long term commitment for green transformation among a critical mass of stakeholders in the South African construction industry. Hence, there is a need for focus on subjective norms (pressure) particularly from the government, to encourage the widespread adoption of green construction in South Africa. Originality/value – Findings present one of the pioneering efforts to empirically validate the influence of behavioural factors on the intention to adopt green construction in South Africa and the outcomes can provide policy directions and baseline data for further research.
From building blocks to digital networks: analyzing critical drivers for social media adoption in the construction sector
(Taylor & Francis, 2024) Tunji-Olayeni, Patience; Oke, Ayodeji Emmanuel; Aliu, John; Babalola, Helen Ifedolapo; Singh, Paramjit; Singh, Jamir; Onyeukwu, Samuel Ukaha
Despite the growing recognition of social media’s potential benefits in the construction industry, there is a lack of in-depth research examining the specific drivers that influence its adoption. Therefore, this study fills this gap by empirically investigating the drivers influencing the adoption of social media in the con struction sector of a developing country such as Nigeria. This objective was achieved through a quantita tive research approach, involving the utilization of a well-structured questionnaire to gather responses from construction professionals, including architects, builders, engineers, quantity surveyors and estate managers. These professionals were sampled using a combination of purposive and snowball sampling techniques. The obtained data underwent analysis using various statistical methods, including descriptive statistics and inferential statistics such as exploratory factor analysis (EFA) and Horn Parallel Analysis. The EFA revealed four clusters of drivers: communication and collaboration, operational efficiency and risk management, marketing and branding and knowledge sharing and learning. The findings of this study offer valuable guidance for construction firms and professionals seeking to harness the power of social media. Understanding the specific drivers within each cluster can inform strategic decisions regarding the selection and implementation of social media tools.

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.

(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.

(2020) Tunji-Olayeni, Patience; Schmidt, Wolfram; Otieno, , Mike; Olonade, Kolawole Adisa; Radebe, Nonkululeko W.; Damme, Henri van; Kenai, Said; Tawiah, Angela Tetteh; Manful, Kuukuwa; Akinwale, Akeem; Mbugua, Rose N.; Rogge, Andreas
Africa is urgently in need of adequate basic infrastructure and housing, and itis one ofthe continents wheremassive construction activities are on the rise. There is a vast variety of potentially viable resourcesforsustainable construction on the continents, and consequently,the continent can bring innovative, greener technologies based on local sources effectively into practice. However, unlike established concrete constituents from industrialised countries in the global North,most ofthe innovation potentialsfromthe African continent have not yet been the focus of intensive fundamental and applied research. This clearly limits the implementation of more sustainable local technologies. This paper presents a case forthe need to first appreciate the rich diversity and versatility ofthe African continent which is often notrealistically perceived and appreciated. It discusses specific innovation potentials and challenges for cementitious materials and concrete technology based on local materials derived from sources on the African continent. The unique African materials solutions are presented and discussed, from mineral binders over chemical admixtures and fibres to reinforcement and aggregates. Due to the pressing challenges faced by Africa, with regards to population growth and urbanisation,the focusis not only put on the technological (durability,robustness and safety) and environmentalsustainability, but also strongly on socio‐economic applicability, adaptability and scalability. This includes a review of alternative, traditional and vernacular construction technologies such as materials‐saving structuresthat help reducing cementitious materials. Eventually, a strategic research roadmap is hypothesised that points out the most relevant potentials and research needsfor quick implementation of more localised construction materials.
