PROJECT MANAGEMENT COMPETENCIES OF INDIGENOUS CONTRACTORS IN NIGERIA
(2016) Tunji-Olayeni, Patience; Mosaku, Timothy O.; Fagbenle, Olabosipo I.; Amusan, Lekan M.
All over the world, governments are talking about reducing spending of capital and recurrent expenditures. Capital expenditures cover cost for major projects such as infrastructure. Moreover, the wealth and worth of a nation is a function of the availability and quality of its infrastructure. It has been noted that indigenous construction firms do not represent a strong source of competition. Consequently, most construction markets in Africa are dominated by expatriates. Governments of most African countries pay huge amount of money to expatriates because of deficiencies in indigenous capacity. This study therefore, identifies and analyses project management competencies required by indigenous construction firms. A quantitative research method was adopted for the study and 72 questionnaires were distributed to indigenous construction firms in Lagos and Abuja, Nigeria. This study revealed cost management, site management, and time management as the most critical project management competencies of indigenous contractors surveyed. The study further revealed that the critical PM competencies of contractors surveyed are hard/technical competencies. The study recommends that indigenous contractors should in addition to hard competencies develop soft/personal competencies which can also facilitate the achievement of project success.
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.

(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.

(Informa UK Limited, trading as Taylor & Francis Group, 2020) Tunji-Olayeni, Patience; Kajimo – Shakantu, Kahilu; Ayodele, Timothy O.; Philips, Bright Idara
Sustainability education for construction students provides an enduring source of indigenous capacity for tackling social, environmental and economic challenges. However, there is limited evidence on students’ perception of sustainable construction in Africa, and Nigeria in particular. This study examines students’ perceptions of sustainable construction, with a case study of a Nigerian university. The study is based on a survey research design, with the use of questionnaires. Statistical techniques such as frequency, percen tages, mean, standard deviation, ANOVA and correlation are used to analyse the data. The findings indi cate that majority of the students were not familiar with the concept of sustainable construction. However, they attached great importance to sustainable construction and were very interested in acquir ing sustainable construction knowledge. The three most common understanding of the students about sustainable construction relates to the use of renewable energy, energy efficiency and waste reduction Moreover, the findings show statistically significant differences between students’ understanding of sus tainable construction and students’ programme, academic level and gender. The findings of the study could enhance concerted efforts by the universities and accreditation agencies towards an intentional and systematic delivery of knowledge and skills that will promote sustainability literacy and transforma tions among future construction professionals in Nigeria.

(IOP Publishing Ltd, 2021) Tunji-Olayeni, P. F.; KAJIMO-SHAKANTU, F; ONI, A. A.
The construction industry has not been able to maximize its full potentials in terms of harnessing the talents and abilities of its diverse workforce. Despite calls for a more pluralistic and inclusive workforce, the construction industry remains male-dominated, thereby limiting its growth potentials. The study examined the effects of workload on family expectations intending to support initiatives on gender equality and equity that will improve working conditions in the industry and eventually increase its performance and competitiveness. The study used questionnaires to achieve the research purpose. The survey was based on a purposive sampling of female construction professionals from different companies in Lagos Mainland, Nigeria. Descriptive statistics and linear regression were used for analysing the data. From the linear regression model, it was revealed that workload affects family responsibility at 73.20%. The significant family responsibilities affected by workload included: making alternative arrangements for children's school transportation, spending time with spouse, spending time with children, taking care of household chores, and going shopping for the family. The study focused only on female construction professionals working in the Mainland area of Lagos, Nigeria. More empirical evidence of the effects of workload on family responsibilities can be obtained by considering female professionals in other regions of Nigeria. These findings have serious implications on job fulfilment, organizational loyalty, employee retention, and organizational performance. The study recommends flexible working hours and other gender-friendly policies to attain the much desired inclusive, profitable and sustainable construction industry.

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.

(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.

(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.

(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.
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.
Promoting construction for sustainability transformation: the perspective of institutional theory
(Emerald Publishing Limited, 2023) Tunji-Olayeni, Patience; Kajimo-Shakantu, Kahilu; Ayodele, Timothy Oluwafemi; Babalola, Olubola
Purpose – Sustainability transformation in the construction industry is vital for the attainment of sustainable development goals. While conventional construction has been at the expense of social and economic sustainability, sustainable construction can enhance environmental, social and economic outcomes for the construction industry and society at large. However, the industry struggles with new initiates because its stakeholders are products of unique institutions which shape their decisions and intentions to adopt new practices. This study assessed the institutional pressures that influence the adoption of sustainable construction to enhance our understanding of other factors that can promote and accelerate the adoption of sustainable construction. 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 influence of institutional pressures on the adoption of sustainable construction. Findings – Mimetic pressures were found to have a significant influence on the adoption of sustainable construction. The decision to adopt sustainable construction was based on the sustainability actions of industry leaders (mimetic pressure). Normative and coercive pressures had no significant influence on the adoption of sustainable construction. Practical implications – Mimetic pressure from competitors and normative pressures is already exerting some pressure on stakeholders to adopt sustainable construction. However, there cannot be a long-term commitment that will yield the needed sustainability transformations without additional normative pressure from learned societies and coercive pressure from the government. As one of the pioneering works from the global south, this study provides empirical validations of the influence of institutional pressures on the adoption of sustainable construction. It also enhances understanding of how institutional pressures from the social context can promote and accelerate the adoption of sustainable construction. Originality/value – The findings present one of the pioneering efforts to empirically validate the influence of institutional pressures on the adoption of sustainable construction.
Research trends in industry 5.0 and its application in the construction industry
(Emerald Publishing Limited, 2023) Tunji-Olayeni, Patience
Purpose – Industry 5.0 provides significant social, environmental and economic benefits over previous industrial revolutions. However, research in the field of industry 5.0 is still at a very nascent stage. Little is known about research trends in the field and its applications in specific sectors as construction which have relatively low sustainability index. Hence, this study aims to explore research trends in industry 5.0 and its applications in the construction industry. Design/methodology/approach – The study adopted a bibliometric analysis with the use of the vosviewer. The main search words used in the study were “Industry 5.0”, “Society 5.0” AND “Fifth Industrial Revolution”. Initial extracted papers with these keywords were 1036. After refining based on language, document type, key words and timeframe, a total of 188 papers were found suitable for the analysis. Findings – The most impactful research on Industry 5.0 to date was from the United States, Australia and Sweden while the journal sustainability was found to be the highest document source on Industry 5.0. The application areas of industry 5.0 in the construction industry include health and safety, collaborative working, waste management, measurement of environmental features (indoor air quality, atmospheric pressure, noise, humidity and temperature) and forecasting of environmental, social or financial outcomes. Research limitations/implications – The study used review based papers which form the bulk of the existing research on industry 5.0. This limits understanding of the practical applications, benefits and challenges associated with the use of industry 5.0. Originality/value – This work contributes to the theory and practice of industry 5.0 by providing baseline data for future research directions on industry 5.0. The work specifically highlights the application areas of industry 5.0 in the construction industry and also indicates the need for questionnaire, interviews or case study based research to enhance understanding of the practical applications of industry 5.0.
Modelling client and construction firm barriers hindering social client relationship management system implementation in the built environment
(Architectural Engineering and Design Management (Taylor and Francis), 2023-11) Ojelabi, Rapheal; Adedeji, Afolabi; Oyeyipo, Opeyemi; Ogunrinde, Olugbenro
The need to foster a strong relationship in the construction industry is vital due to the level of dependency among stakeholders in the sector. The social CRM system has been deployed as a relationship tool in most sectors, but its infusion in the construction industry is not resounding. Hence, the study investigates the barriers to Social Client Relationship Management application in fostering sustainable relationships among construction stakeholders. It models the relationships between the associated barriers between the client and the construction organisations affecting the implementation of social CRM systems. A quantitative research approach was adopted, and a face-to-face questionnaire survey was conducted on 200 construction experts selected from 40 construction projects in Lagos Island. The targeted construction experts were elicited for the survey using purposive sampling techniques. Data from the survey were analysed using SPSS 21 data analytics techniques like frequencies and percentages. Also, the study used SmartPLS (v.3.2.3) to develop the structural model. Findings from the study revealed a strong relationship between the significant factors associated with the clients and construction organisation hindering Social CRM system implementation in the built environment. The findings can assist built environment stakeholders in developing strategies to control the factors associated with the client and construction organisation militating against Social CRM implementation in the construction industry.

(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.
