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.

Team commitment and performance of construction project in Nigerian construction industry

<p>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.</p>

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.

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

This study was motivated by the need to deploy building information modeling (BIM) and its technologies to improve the realization 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 paper 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 modeling (TISM) approach. The TISM displayed an eleven-level hierarchy of hindrances made up of independent, dependent, and linkage categories. Based on the 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.

Evaluation of Construction Contract Management in the Nigerian Construction Industry

Construction projects in Nigeria are most of the time not completed within schedule, cost and quality specifications and at times project abandonment. In evaluating the construction contract management practice in Nigeria with the objective of ascertain the tendering methods, usage of construction document and the common techniques used in construction planning. One-way analysis of variance and multiple regression analysis were used in the analysis. The analysis of the respondent score relating to hypothesis for using regression model showed the regression equation as Y=10.43983+0.7525x1+0.3419x2+0.5256x3+0.1874x4. The coefficient of multiple correlation (R) was 0.909124 and this means that 91% positive correlation exist between the successful implementation of construction contract. The independent variables explain 83% of the variables in successful implementation of construction contracts and the remaining 17% could be attributed to other unspecified factors.

There are problems of project abandonment, delays, disputes among the participants in the construction projects, difference between the tender cost, and initial cost and construction cost in most public building projects as a result of inflation and cost overrun in Nigeria. The aim of this study is to examine the influence of inflation and cost overrun on public sector projects in Nigeria and proffer solution on ways to minimize the problems associated with these two variables impacting public sector construction projects. This research work adopted a quantitative research method. This involved design of questionnaires and also collection of secondary data. Fifty questionnaires were administered to public sector professionals and data on ten public buildings projects were collected in Lagos State. The major finding from this study is that inflation and cost overrun affect most public building projects in Lagos State.

Moderating effect of project size on the relationship between COVID-19 safety protocols and economic performance of construction projects

PurposeThe COVID-19 health crisis has brought about a set of extra health and safety regulations, and procedures to the construction industry which could influence projects' economic performance (EP). The aim of this paper is to examine the effect of adopting COVID-19 safety protocols on construction sites on the economic performance (EP) of construction projects.Design/methodology/approachEmploying the survey method using a structured questionnaire, data were collected from small- and large-sized construction projects in Nigeria and analysed using partial least squares structural equation modelling (PLS-SEM) technique.FindingsThe findings reveal that job re-organization and sanitization have negative significant effects on EP, while social distancing and specific training have no effect on EP. Furthermore, project size moderates the relationship between job re-organization, sanitization, specific training and EP with the stronger effect on the relationships observed in big projects, except for the relationship between sanitization and EP where the moderating relationship is stronger in small projects. However, there is no significant moderating effect of project size on the relationship between social distancing and EP.Practical implicationsAs construction project sites continue to operate amidst strict safety protocols, this study offers theoretical and practical insights on how construction projects can adhere to the safety protocols while performing economically.Originality/valueThe originality of this study's findings stems from the fact that it is among the first to provide greater insight on how construction projects have fared economically considering the impact of the various COVID-19 protocols.

Risk Management and Quality Projects Delivery in Nigeria's Construction Industry

The delivery of poor quality construction projects in Nigeria presents a problem which this paper attributes to low levels of Risk and Risk Management awareness, understanding and practice. The little or none existence of a formalised and regulated Risk Management process means the construction industry which normally has a high presence of risk is not adequately managed hence an uncontrolled and unmitigated effect on the value and quality of projects delivered. This paper verifies this submission by investigating Risk Management awareness and practice levels in the industry through a survey targeting experienced personnel who by their project positions are expectedly knowledgeable enough to provide credible feedback. A review focused on select Risk Management literature with an objective of creating the necessary knowledge and understanding needed to practice and apply Risk Management, and also most importantly, evaluate how it relates and influences the delivery of quality construction projects of value. This paper presents results fed by questionnaires specifically designed and administered to unravel and establish Risk Management awareness and practice levels. It reveals low, inconsistent and a non-formalised Risk Management practice in the industry under assessment. It reveals the absence of a uniform regulatory authority. It presents an acceptance of Risk Management as a viable solution to achieving quality projects of value and performance. Based on this paper's findings, a justified case is made for a more formal, consistent and participatory Risk Management process in the Nigerian construction industry. In making this case, this paper posit that if applied, the industry will experience the delivery of much improved projects of value, quality and performance.

Integrated project delivery in the Nigerian construction sector: an unexplored approach from the stakeholders’ perspective

PurposeOver the past years, high waste and inefficiencies in the construction industry may have contributed to many projects failing to meet clients’ expectations. Among the new project delivery mechanisms to tackle this problem is integrated project delivery (IPD). IPD has been proved as a mechanism that increases stakeholders’ collaboration at the early stage and delivers the highest value-for-money projects. In Nigeria, research regarding practitioners in the application of IPD in construction delivery is scarce. Thus, this study aims to investigate the level of awareness, issues hindering the implementation of IPD and proffer solutions to promote the use of IPD in project delivery.Design/methodology/approachQualitative research was adopted. Twenty virtual interviews via Zoom and Whatsapp Videos were used to collect data from the selected participants and analysed via a thematic method. This is because of the unexplored dimension of the issues.FindingsResults show that practitioners are aware of IPD but lax in the application. The emerged issues hindering the adoption and implementation of IPD were grouped into technological, legal, financial and cultural in Nigeria’s context.Research limitations/implicationsThis study is restricted to the relevance and hindrances facing the usage of IPD in the Nigerian built environment. The study proffers solutions to promote the use of IPD in the built environment via a qualitative approach.Practical implicationsThis paper will contribute towards stirring Nigeria’s stakeholders to create an enabling environment within the industry via IPD friendly policies and promote the use of IPD on construction projects.Originality/valueThis paper is one of the few papers that attempted to uncover issues that hinder the use of IPD on construction projects in Nigeria via a qualitative approach.

Examining the awareness and usage of cyber physical systems for construction projects in Nigeria

PurposeIn recent times, the construction industry is being influenced by technological innovations when delivering a better, more effective and efficient desired project, cyber-physical systems (CPSs) offer a coupling of the physical and engineered systems by monitoring, coordinating, controlling and integrating their operations. This study aims to examine the level of awareness of professionals and usage of CPSs for construction projects in Nigerian construction industry.Design/methodology/approachThe target population for this study was the professionals in the construction industry consisting Architects, Quantity Surveyors, Engineers and Builders. Data collection was through the use of a structured questionnaire administered to the target population. The data was analyzed by using statistical tools.FindingsThis study concluded that the construction professionals in the Nigerian construction industry are mostly aware about the heating, ventilation and air conditioning (HVAC) systems, global positioning system, microphone, speakers and camera as the most widely used CPSs in construction industry. HVAC systems was also found to be the mostly adopted technologies in the construction industry.Originality/valueThis study recommended that platforms that increase the awareness and encourage the usage of CPSs in construction industry should be encouraged by stakeholders concerned with management of construction projects. Such include electronic construction and adoption of blockchain technology.

Effect of energy management and waste management on schedule performance: role of technological complexity and project size.

Schedule overrun is one of the greatest hindrances to construction project performance, thereby making schedule management an integral part of construction project management. The aim of this study is to examine how the effect of sustainable energy management (SEM) and sustainable waste management (SWM) on schedule performance (SP) is mediated by technological complexity (TC) and moderated by project size (PS). Data were obtained by means of a questionnaire survey of 168 completed construction projects in Nigeria. The partial least squares structural equation modelling (PLS-SEM) technique was adopted in analysing the collected data. The results show that TC partially mediates the relationship between SWM and SP, while TC fully mediates the relationship between SEM and SP. Also, the findings of the study indicate that the negative effect of SWM on SP will be greater with large PS. This study contributes to previous studies in the area of schedule management, by providing empirical proof to explain the means through which SWM and SEM could lead to SP through TC, and how this would vary depending on PS. The study proffers ways for contractors to improve the SP of their projects considering PS and TC.

LABOUR–SPECIFIC FACTORS INFLUENCING THE VOLUME OF CONSTRUCTION WASTE GENERATION IN THE CONSTRUCTION INDUSTRY

The construction industry generates a large volume of waste which distorts the aesthetics of the environment and contributes to the impediments to achieving social, economic and environmental dimensions of sustainability. Construction waste impact project schedule, cost, and derails contractor's profit, leads to claims and disputes. Construction tradespeople who are the frontline workers have a role to play in the waste generation of construction projects irrespective of the level of development of a nation. This study assessed the labour-specific factors influencing construction wastes generation on construction projects in Nigeria. The well-structured questionnaire conveniently administered to construction tradespeople in active construction sites in Port Harcourt was used to gathered data. Garnered data were analysed using the mean item score and Kruskal-Wallis H tests. The study found that the most significant labour-specific factor that influence construction waste generation are workers' mistakes/errors leading to rework, poor attitudes of workers, shortage of skilled workers/use of unskilled, poor workmanship, and lack of experience. The study recommended for the organisation of adequate training to improved workers knowledge and skills needed to execute projects tasks.

Correlation between Petroleum Pump Price Volatility and Selected Building Materials Prices of Construction Projects in Nigeria, 2011 – 2020

The issue of construction material prices would never cease to exist as building projects are being carried out on regular basis. This study examined the statistical relationship that exists between petroleum crude oil price volatility and prices of selected building materials in Nigeria. These materials include cement, block, tile and reinforcement bars, and were selected via field survey owing to their cost implication to building and importation regularity. Data on Petrol Pump Price Volatility were obtained from the Central Bank of Nigeria (CBN) statistical bulletin and covered a period of 2011 to 2020. The inferential analysis carried out between petroleum pump price and the prices of cement, block, tile and reinforcement bar show the existence of strong positive relationship, with correlation coefficients of 0.872, 0.920, 0.820 and 0.864 respectively. This shows that 1 Naira increase in petrol pump price reflects a similar increase in the prices of building materials indicating that petrol pump price is a strong determinant of construction material prices. This study concludes that there is need for the formulation of appropriate fiscal policies devoid of political sentiments in mitigating the effect of petrol pump price on building material prices. The study therefore, recommends the diversification of the economy through the revitalization of the Ajaokuta Iron & Steel, Itakpe Iron Ore Mining Companies as well as other steel industries which can assist in increasing the local production of building materials and other equipment, and by so doing reducing the effect of petrol pump price as well as curtailing the upshot of other macroeconomic factors on the economy.
