Circular Design Strategies and Economic Sustainability of Construction Projects in Nigeria: The Mediating Role of Organizational Culture

The need to incorporate circularity into construction is a global concern. The current linear consumption of construction materials is economically unsustainable in the midst of growing financial fears. The goal of this study is to probe the effects of circular design strategies (CDS) on the economic sustainability of construction projects (ESCP) based on the mediating role of two dimensions of organizational culture (OC). The paper observed the mediating effects of OC in the association between CDS and ESCP under the premise of the circular economy (CE) theory. The Partial Least Squares-Structural Equation Modeling (PLS-SEM) method was deployed to analyze 359 survey feedbacks obtained from Nigerian construction firms. This paper's key contribution is the confirmation of CDS's significant influence on ESCP and the partial effects of OC on ESCP in the Nigerian construction sector. Additionally, Hierarchical Culture (HC) diminishes the relationship between CDS and ESCP. This demonstrates the necessity for construction companies to create and embrace a more inventive culture—like the Development Culture (DC)—in order to promote circular practices and ultimately support the financial viability of building projects in Nigeria.

Investigation of Community Engagement in Sustainable Construction Projects: Case Studies from Nigeria

This study investigates the role of community engagement in sustainable construction projects in Nigeria, focusing on three case studies: a green residential building in Lagos, an eco-friendly community center in Abuja, and a sustainable water infrastructure project in rural Kano. Using a mixed-methods approach, data were collected through interviews, surveys, and document analysis. The research identifies significant variations in engagement practices, with Lagos showing high engagement levels, leading to greater community acceptance and better environmental outcomes. Key success factors include strong leadership, adequate funding, and effective communication, while challenges such as socio-cultural barriers and political interference were noted. The findings emphasize the importance of sustained, tailored engagement strategies to enhance project sustainability and community support. This study contributes to the literature by providing empirical data on the long-term impacts of community engagement, offering insights for policy makers and project managers to improve community participation in sustainable construction.

Revolutionising construction safety: benefits of harnessing artificial intelligence tools for dynamic monitoring of safety compliance on construction projects in Nigeria

PurposeThis paper evaluates the benefits of harnessing artificial intelligence (AI) tools for safety compliance on construction projects in Nigeria.Design/methodology/approachThis study employed a specialised approach by combining qualitative and quantitative approach. The study carried out a brief systematic literature review (SLR) to identify the variables of the study. These variables were prepared in a questionnaire which was distributed among professionals within the Nigerian construction sector using purposive sampling. A total of 140 questionnaires were retrieved. The collected data were analysed using Relative Importance Index (RII), Ginni’s Mean (GM) and exploratory factor analysis (EFA).FindingsThe analysis revealed that all the identified benefits hold considerable importance, with an average RII of 0.86, with real-time monitoring as the most prominent advantage. However, using the GM which was 0.861, the study identified “mitigation of hazards on worksites” as the stationary benefit of AI in safety compliance.Research limitations/implicationsThe study was conducted exclusively within Nigeria’s Federal Capital Territory, using a cross-sectional survey approach.Practical implicationsThe results will be valuable for professionals and practitioners in the Nigerian construction sector, as they will acquire insights into the potential advantages of utilising AI tools for monitoring of safety compliance on construction projects.Originality/valueThe study adopted a robust approach by identifying the stationary benefit using the GM in combination with RII and EFA.

Determinants of poor planning in public sector construction projects in Nigeria

The study assessed the determinants of poor planning in public-sector construction projects in Nige­ria. The paper adopted a questionnaire survey. A struc­tured questionnaire was administered to 217 construc­tion professionals, out of which 156, representing 71.9%, correctly filled questionnaires were analysed. The study deployed descriptive statistics such as mean and stand­ard deviation for data analysis. Results indicated that the primary determinants of poor project planning are the need for qualified personnel, with a mean of 4.70; experience, with a mean of 4.63; and poor communica­tion among the project teams, with a mean of 4.63. The significant factors influencing the implementation of project planning in public sector construction projects include natural occurrences, the use of computers and ICT, differing approaches of those who produce the plans and those who deliver the project, the leadership of the project team, application of planning techniques, only trained project managers should plan the project, non-availability of labour, lack of experience. The criti­cal barriers to project planning implementation in pub­lic construction projects include lack of communication, performance problems, political influence, dissatisfied project teams, abandonment of the project, time over­run, absence of new technology and software for plan­ning, compromised project quality, and wrong estima­tion. The research suggests that contractors involved in public sector construction projects in Nigeria should enhance their planning and performance through various measures. These measures include conducting financial and ethical client checks, employing dedicated project managers, utilising com­puterised planning systems, and improving team communication through reliable channels.

Assessment of Construction Practitioners’ Knowledge Sharing Attitude in Construction Projects in Nigeria

Individuals such as construction practitioners (CPs) are the focal point of knowledge sharing (KS). KS plays a cardinal role in knowledge management (KM). It is recognised as one of the most crucial aspect of KM which leads to better performance of organisations and construction projects. Literature has shown that KS success is largely driven by individual level variables such as attitude. Studies on KS largely neglect the individual level variables, e.g. perception, motivation and attitude. Hence, there is a lack of knowledge on the influence of the determinants of attitude on construction practitioners’ (CPs’) KS attitude. Therefore, this study aimed at assessing the influence of the determinants of attitude on CPs' KS attitude in construction projects with a view to improving knowledge sharing among CPs. The determinants of KS attitude and their components were identified from literature and were used to conduct a survey to assess the CPs' KS attitude. Quantitative method was adopted for this research and the data were collected using structured questionnaire administered to 174 Construction practitioners using Stratified Random Sampling. Data were analysed using Structural Equation Modelling. The study identified six determinants of KS attitude with four independent (perceiver, target, intensity and persistence) and two dependents (cognitive and affective). It was found out that the CPs perceiver, target, intensity and persistence as determinants of KS has influence on KS attitude. The study also found a high significant influence between measures of CPs’ motivation (intensity & persistence) KS attitude compared to measures of their perception (perceiver & target) and the strongest influence is between CPs intensity and their cognitive. The study concludes that CP’s as the perceivers and KS as what is been perceived (target) do not affect CPs knowledge sharing attitude, instead intensity and persistence (motivation) does. This study recommends that CPs should be educated about their perception of KS. The study recommends that construction practitioners level of motivation should be increased because motivation is what derives them to share knowledge rather than perception.

AN ANALYSIS OF THE IMPACT OF PROCUREMENT AND COMMUNICATION MANAGEMENT ON THE PERFORMANCE OF CONSTRUCTION PROJECTS IN NIGERIA

The construction sector plays a vital role in driving economic growth and development in Nigeria. However, it faces significant challenges, particularly in project performance, which can be attributed, at least in part, to ineffective communication and procurement management. This research aims to evaluate how communication and procurement management impact the outcomes of construction projects in Nigeria. To conduct this study, a quantitative research design was employed, utilizing a survey questionnaire administered to 260 construction professionals. The data collected underwent analysis employing various techniques such as descriptive statistics, confirmatory factor analyses (CFA), exploratory factor analyses (EFA), and structural equation model (SEM) utilizing software including the Statistical Package for Social Sciences (SPSS), Microsoft Excel, and LISREL (Linear Structural Relations). The SEM analysis results revealed that 31 out of the 35 hypotheses used in the study were validated. Among these, the strongest relationships observed were those between procurement management and time performance, procurement management and cost performance, time performance and cost performance, time performance and quality performance, and communication management and time performance, in that specific order. This demonstrates the critical role of effective communication and procurement management in achieving successful construction projects in Nigeria. Additionally, the analysis of factors affecting the implementation of procurement and communication management in the Nigerian construction industry highlighted the need for stakeholders to be proactive in developing strategies that facilitate effective implementation of these practices to enhance project performance. The study also emphasizes the importance of establishing effective procurement policies and regulations, embracing technology, building capacity, managing stakeholders, and continuously improving project management practices to elevate project performance in the Nigerian construction industry.

Impact of Project Management Practices on Cost and Time Overruns in Construction Projects in Nigeria

A major contributor to economic growth in Nigeria, the construction sector is frequently beset by large cost and schedule overruns that jeopardize project profitability and impede the development of infrastructure. This study looks into how project management techniques affect these overruns in building construction projects in Nigeria. The goal of the study is to pinpoint the major project management variables that lead to overspending and delays while also offering recommendations for best practices to address these problems. A mixed-methods strategy was used, integrating qualitative case studies with quantitative data analysis. Project engineers, contractors, Architects, and Technicians were given standardized questionnaires to complete about a variety of Nigerian building projects. In-depth interviews and focus groups were also held to acquire a deeper understanding of the real-world difficulties and experiences encountered in the field. The study pinpoints several crucial project management techniques that affect time and cost performance. The results show that Inadequate construction site management and supervision ranked 1st with an RII of 0.7877, Improper construction techniques and lack of experience of the consultant came 2nd and 3rd with RII of 0.7215 and 0.7213 respectively. Late payments during work progress and Use of improper equipment are contributors to project time overrun; while, factors affecting cost overrun are fluctuation in building material costs ranked 1st with RII of 0.7354, frequent design changes, (0.7138), omissions and errors in bills of quantities (0.6754), import of construction materials (0.6754). The report suggests enhancing project management through effective resource management techniques, ongoing training and certification programs, and implementing advanced technology to improve communication, resource management, and planning precision, contributing to sustainable growth in Nigeria's construction industry.

Developing a framework for mitigating pilfering: a case study of selected Nigeria’s construction sites via soft system methodology

Studies regarding mitigating pilfering practices on construction sites via a framework are scarce in Nigeria. Hence, this research explored the root cause of pilfering practices on Nigeria’s construction sites and developed a framework to mitigate the unethical practices. This research employed a soft system methodology (SSM) to understand pilfering practices on construction sites in Nigeria. The mechanism permits an alternative method to mitigate pilfering practices on construction sites via a developed framework. Face-to-face interviews were conducted with practitioners in alignment with the SSM seven steps, and findings were presented. The study engaged six construction sites in Lagos, Nigeria. Findings show that besides evidence of pilfering practices across the selected construction sites, the absence of a framework to mitigate pilfering practices on construction sites, especially in small and medium construction firms’ sites, threatens value-driven construction projects in Nigeria. The study’s findings developed a framework that would enhance the concept of post-contract cost control and reduction of construction overhead costs during the execution phase of projects through mitigating pilfering practices on construction sites. This is a germane mechanism for meeting clients’ and contractors’ requirements and satisfaction.

Mediating effect of ecospirituality on the relationship between green training and voluntary workplace green behaviour in construction projects in Nigeria

PurposeThe impact of mankind on the environment and the usage of natural resources might be influenced by spirituality, through the consciousness of creating an improved moral sense regarding the consequences of human activities and the necessity to alter these to achieve sustainable development. However, the spiritual element in the form of ecospirituality (ES) has not been sufficiently considered in pro-environmental studies as it relates to the influence of green training (GT) on voluntary workplace green behaviour (VWGB) in the construction sector. This study aims to determine the effect of GT on VWGB and the mediating effect of ES on the relationship between GT and VWGB on construction projects.Design/methodology/approachThis study’s data were gathered through a questionnaire survey of construction site managers and project managers by adopting the probability sampling method. 249 appropriately completed questionnaires were returned. The data obtained were analysed by means of the partial least squares structural equation modelling technique (PLS-SEM).FindingsThe outcomes of the study show that GT has a significant positive impact on VWGB, while ES has a significant mediating effect on the relationship between GT and VWGB, both supporting the study’s hypotheses.Practical implicationsThese findings point to the fact that the hitherto conflicting results reported in earlier studies on the GT–VWGB relationship can be attributed to the lack of consideration given to ES. Hence, special attention should be given to ES.Originality/valueThis research presents actions to enhance the transformation of GT into VWGB by giving due consideration to ES, which was not taken into account in previous studies.

Buildability Issues in Building Construction Projects in Nigeria

Buildability terminology is adopted for the effect of design on construction and as an essential professional input of a builder during the design stage in project execution. Thus, this research determined buildability issues on building projects. The objectives assessed the factors responsible for buildability issues and examined mitigation strategies on selected construction projects. Primary data were collected through the distribution of sixty questionnaires to construction professionals in fifteen ongoing construction projects handled by Ambrose Alli University, Ekpoma; Irrua Specialist Teaching Hospital; Esan West Local Government and Esan Central Local Government purposively sampled. The return rate of questionnaires administered was 83.3%. The data obtained were analyzed using mean item score and relative importance index. Results revealed the prevalence of buildability issues in the study area; especially inadequate cash flow from client, poor information flow between designers and contractors and omitted drawing details. The most prominent factor responsible for buildability issues being improper planning and poor site layout (RII = 0.884) while the most predominant strategy to mitigate buildability issues was producing detailed working drawings (RUI = 0.904).

Team commitment and performance of construction project in Nigerian construction industry

Project success requires team commitment, which is a product of an encouraging culture of cooperation and teamwork among project team members. The research work aims to ascertain which components of team commitment affect the performance of construction projects in Nigeria. The research adopted a quantitative design where questionnaires were used for data collection. Out of 1233 questionnaires distributed, 975 were received with valid responses and used for data analysis. Data were analysed descriptively using percentage, mean score, and relative agreement index. The study showed the factors of team commitment having an effect on project performance, as rated by the respondents, to be: Normative component: “Project team members owe a great deal to this organisation”; “Members of the project team do not feel it is right to quit the project before completion”; “This organisation has a great deal of personal meaning for project team members”. Affective component: “This organisation deserves the loyalty of project team members”; “The project team considers the team’s problems as their own. Then, “One of the few negative consequences of leaving this organisation will be the scarcity of available alternatives” is for continuance. In conclusion, the emotional attachment of the team members and sense of obligation to the project team and construction organisation are the driving forces behind pushing for the successful outcome of projects within the Nigerian construction industry.

Modelling the Hindrances to Building Information Modelling Adoption on Construction Projects in Nigeria

This study was motivated by the need to deploy building information modelling (BIM) and its technologies to improve the realisation of construction projects. Prior to the introduction of BIM, the construction industry was confronted with obstacles and was sluggish in adopting change. Until recently, existing BIM research has mostly focused on large enterprises and there has been an apparent pattern of underrepresentation of medium-sized firms in BIM- related studies. Thus, the purpose of this article is to investigate the major hindrances to BIM’s adoption in construction projects as well as the dynamics of these hindrances in a developing country like Nigeria, using the total interpretive structural modelling (TISM) approach. The TISM displayed an 11-level hierarchy of hindrances made up of independent, dependent and linkage categories. Based on the Matrice d’Impacts Croises Multiplication Appliqué a Classement (MICMAC) analysis, “Lack of skilled BIM personnel” had the highest driving and the lowest dependence (independent) power, thus indicating its importance in the adoption of BIM. The findings further showed that “Lack of awareness of BIM” and “Resistance to change” are critical for the adoption of BIM in construction projects. The drivers (dependents) for the ease of adoption of BIM by policymakers and practitioners within the built industry are thus defined in this study. This study contributes to the early studies of BIM adoption from a developing country’s perspective.

Influence of rework on construction project performance in Nigeria

One of the key reasons for setbacks in construction projects in Nigeria is rework. In order to create efficient containment and reduction strategies, this study examined the causes of rework in construction projects, its influence on construction project performance, and proffer solutions to the causes of rework based on extant studies. A total of 140 questionnaires were distributed to the stratified population of various construction professionals. One hundred and eight questionnaires were duly completed and returned. Data were analysed using mean weighted value and regression analysis. The data analysis results revealed that poor coordination of design, the lack of effective quality management practices and alteration made at the clients' request were the topmost causes of rework. In addition, poor morale, time overrun and disputes were the first three most rated impact of rework inimical to construction project performance. It was concluded that the incidence of rework influences projects performance as it brings about poor morale of the workforce and dissatisfaction among end user. It was recommended that adherence to the solutions proffered to the topmost causes of rework will go a long way in improving construction project performance.

Barriers to environmental impact assessment implementation for construction projects in Nigeria

PurposeEnvironmental impact assessment (EIA) is one of the best approaches to identifying, preventing, minimising, compensating for any unfavourable impacts on the environment and also encouraging sustainability. This paper aims to investigate the barriers to EIA implementation for construction projects in Nigeria.Design/methodology/approachThe study adopted a survey research technique. The snowball sampling approach was adopted to identify key stakeholders in EIA practice for the administration of questionnaire. A total of 187 questionnaires were administered and a response rate of 60% (113 questionnaires were adequately filled and returned) was achieved. Descriptive and inferential statistics were utilised in analysing elicited data.FindingsThe results from data analysis showed that, “failure to influence the decision-making process/multiple conflicting decision-making”, “unstable regulatory regime”, “lack of available, accessible and fit-for purpose data”, “inadequate public knowledge of legal issues” and “poor provision of information” were the top most five barriers to EIA implementation for construction projects in Nigeria. Also, the results from the research show a statistically significant degree of agreement on the rankings by the groups of key stakeholders in EIA concerning the barriers to EIA implementation for construction projects.Originality/valueThis paper contributed to more effective EIA studies by drawing attentions to barriers to EIA implementation for construction projects. An understanding of these barriers can help key stakeholders in the construction industry of developing countries such as Nigeria to facilitate development of methods required in reducing barriers to EIA implementation in the construction sector.

Modelling rework cost for TETFund building construction projects in Nigeria

Accurate predictions of rework cost enable contractors to evaluate how successful their projects are likely to be, thus, improve their operations and productivity. Studies have developed project scope-based and non-scopebased rework cost predictive models. However, researchers have criticized the accuracy of these models because of their weaknesses in giving individualistic treatments to project scope-based and non- scope-based rework cost influencing factors. This study therefore aimed at developing rework cost predictive models that combine the synergistic effects of both project scope- based and non-scope-based rework cost factors. 440 sample size was drawn from 2,638 population of Tertiary Education Trust Fund (TETfund) building projects constructed between 2009 to 2015. Data of 287 (65%) of 440 (sample size) of completed TETfund building projects on project scope factors as well as the extent of influence of the non-scope factors on cost of rework in TETfund building projects was collected. Principal Component Analysis (PCA) and Multiple Linear Regression (MLR) were used in developing an integrated rework cost predictive model. More accuracy was achieved in the integrated model through the incorporation of impact of project scope and non-scope influencing factors into rework cost prediction model, this increased the variability in cost of rework to R2 = 0.759 (75.9%), while errors in rework cost predictions reduced by as much as 9.75%.The model serve as useful tool used to enhance accuracy of rework cost predictions for TETfund building contractors, thus reduce cost of rework for building construction projects.
