Abstract
The challenges confronting the Nigerian construction industry which led to the adoption of supply chain management (SCM) practice were evaluated in this chapter. It was discovered that the Nigerian construction industry is confronted with fragmentation and poor information management. The stakeholders within the Nigerian construction industry proposed the adoption of SCM to overcome the fragmentation and other shenanigans facing the industry. This chapter revealed that construction supply chain (CSC) practices within the Nigerian construction industry focus on waste elimination by adopting the lean concept. The focus on the lean concept could be attributed to the numerous research related to lean or the enormous waste emanating from the Nigerian construction industry. Regardless of the emphasis on lean, the Nigerian CSC is still confronted with fragmentation and heavy waste generation. Thus, this chapter proposed the adoption of principles and technologies driven by the fourth industrial revolution (4IR) is a paradigm shift for the management of CSC in the country. It was discovered in this chapter that Nigerian construction supply stakeholders had not embraced the technologies and principles of the 4IR. The failure to adopt the technologies driven by the 4IR is attributed to the absence of a CSC model that depicts the management of CSC in alignment with the 4IR. This chapter called for developing a SCM model for the Nigerian construction industry in tandem with the principles and technologies of the 4IR.

Abstract
Purpose
The purpose of this paper is to evaluate the adoption of quantitative risk analysis techniques (QRAT) on construction projects in Nigeria with a view to providing better understanding on the state of these techniques.
Design/methodology/approach
Questionnaire survey was employed in gathering data for the study. The paper assessed the level of knowledge, awareness, utilization, success and the factors influencing the adoption of QRAT. The primary data employed were obtained by using multiple-choice questionnaire administered to the selected large construction companies in Nigeria.
Findings
The result of the study revealed a low level adoption of QRAT, and this inhibits Nigerian construction industry from taking full advantage inherent in QRAT. Also, it prevents the analysis of risks peculiar to construction projects. Furthermore, inadequate training and record keeping on risk management were identified as significant factors affecting the adoption/utilization of QRAT on construction projects.
Research limitations/implications
Multiple-choice questionnaires administered to the respondents (architects, quantity surveyors, builders, structural engineers, civil engineers, and mechanical and electrical engineers) were limited to the selected large construction companies in the category D of the Nigerian Federal Tender Board.
Originality/value
This empirical inquiry provided strong evidence on the state of QRAT of construction projects in Nigeria. The findings revealed insightful perspectives to understand construction project QRAT in its entirety. For stakeholders, understanding and addressing the complexity help to improve project planning and implementation.

Abstract
Purpose
The purpose of this paper is to evaluate critical factors that impact public sector organizations’ (PSOs) performance in PPP contracts with a view to improving their capabilities toward efficient project delivery and attracting more private sector investments.
Design/methodology/approach
The research methodology is a quantitative approach which commenced with an in-depth literature review that provided the basis for identification of the variables that were evaluated through a structured questionnaire. Respondents were professionals from stakeholders’ organizations that had been involved in PPP contracts in the Southwestern region of Nigeria selected using respondent driven sampling technique. These include industrial practitioners from governmental-based organizations (ministries, agencies, corporations/parastatals, etc.), private developers/concessionaires, law firms, and banks, among others. Data collected were analyzed using mean, relative significance index) and factor analysis.
Findings
The critical performance factors of PSOs in concession contracts clustered under nine components. These were technical, legal, political, finance, market maturity, economic, procurement process, performance guarantee and degree of regulation. PSOs’ capability development measure in countries newly experimenting with concession model is expected to focus on these factors for improved project delivery.
Research limitations/implications
The study provided implications for capabilities improvement, legislation and policy making with respect to PPP transactions in countries newly experimenting with PPP contracts. This is highly significant to improving the capabilities of PSOs and attraction of more private sector partnership in infrastructure delivery through the concession model.
Practical implications
The study provided implication for capabilities improvement, legislation and policing with respect to PPP transactions in countries newly experimenting with PPP contracts. This is highly significant to improving the capabilities of PSOs and attraction of more private sector partnership in infrastructure delivery through concession model.
Originality/value
Previous studies on PPP performance had either focused on the projects or generalized the performance assessment to PSOs and private investors. This study extended the researches on PPP performance by revealing factors specific to the public sector stakeholders.

Abstract
Purpose
The build-operate-transfer (BOT) model is fast becoming a sustainable tool for remedying the deficiencies of public financing of hostel facilities in Nigeria. Being a new concept in Nigeria, this study aims to assess clients’ organizations perspective of risk factors associated with BOT model with a view to providing information for their effective management.
Design/methodology/approach
Quantitative descriptive analysis was used, which was based on primary data obtained through questionnaire survey. The respondents included architects, engineers (structural/civil/mechanical/electrical), builders and quantity surveyors who were officials in the physical planning development and works departments of five sampled universities in the southwestern Nigeria who executed at least one BOT hostel project. A total number of 45 copies of questionnaire were administered, out of which 35 copies representing a response rate of 77.8 per cent were retrieved. Data analysis was undertaken using descriptive statistics: percentages, mean item score and relative importance index.
Findings
Severity of the risk factors specific to BOT model for hostel development was revealed. Besides, conceptual allocations and mitigation measures were suggested against each risk factor.
Practical implications
Private sector investor would find the results of this research useful in preparing robust BOT contract packages through the understanding of the nature of risk factors associated with the procurement model.
Originality/value
With limited evaluation of BOT in hostel facilities procurement, this study developed a simplified approach to management of risk factors associated with BOT model in the education sector.

Abstract
Purpose
The clarity of requisite roles of public sector organizations (PSOs) for successful procurement of public-private partnership (PPP) infrastructure in Nigeria is not well-established as the country is portrayed with the rising statistics on the haphazard pattern of operation of PPP model for infrastructure procurement. This has greatly beset the expected performance of a number of PPP projects which were intended to bridge the infrastructural deficit in the country. This study therefore examined roles the performed by PSOs in PPP infrastructure procurement with a view to delineate PSOs obligations and consequently improve project success.
Design/methodology/approach
The study was based on structured questionnaire survey of professionals in PSOs who have been involved in PPP infrastructure procurement in Southwestern Nigeria. The sampled professionals were drawn from a build-up of network through a referral chain by the adoption of respondent-driven sampling (RDS) method. The data collected were subjected to mean score analysis and Kruskal–Wallis test.
Findings
The study found that roles pertaining to management of variation, apportionment of penalties and abatements, select preferred bidders, establish management approaches for PPP risks are infrequently performed by PSOs in Nigeria. Whereas these roles are critical to successful procurement of PPP infrastructure as they are prerequisites for PPP infrastructural project success.
Originality/value
The study provides information that would be useful for developing countries with evolving PPP markets for enhanced project delivery.

Abstract
Purpose
The purpose of this paper is to develop compensation mechanisms against risks factors that impact private party’s costs in concession-based projects as a basis for minimizing failure rate of concession contracts.
Design/methodology/approach
The study extended earlier work on the factors that impact private party’s costs in concession-based projects by developing compensation mechanisms against the risks factors. It commenced with semi-structured face-to-face interviews which were launched with different stakeholders organizations that had been involved in PPP contracts in the Southwestern Nigeria. Responses from the interview were analyzed using interpretative phenomenal analysis via ATLAS.ti6/7. The mechanisms identified from literature review were assessed through structured questionnaire which were administered on professionals selected from governmental-based organizations (ministries, agencies, corporations/parastatals, etc.), private developers/concessionaires, law firms, banks among others, using the respondent-driven sampling technique. The robustness of the quantitative data was achieved by including the initial respondents to the interview in the questionnaire survey. The quantitative data were analyzed using percentile for better understanding of the flexibility between “most” and “more” preferred mechanisms. The criterion for the selection of appropriate mechanism(s) for the factors was based on minimum average of 20.0 percent (the ratio of maximum percentage (100 percent) of the respondents to total number of variables) suggesting the five identified mechanisms. The results in both cases of qualitative and quantitative assessments were compared. Based on the convergences of the findings, preferred compensation mechanisms were developed against concession contract risk factors.
Findings
Options of mechanisms were developed against specific investment risks that are consequent to the defaults of the public party in PPP contracts. The findings indicate that the mechanisms in extant literature with respect to administration of traditional models are relevant for PPPs. The study, however, identified new concepts, including “compensative” “zero compensation,” “equitable sharing” and “adjustment of concession period,” which are suitable in specific cases of PPP contracts.
Practical implications
The study contributes to the body of knowledge on mechanisms for improving PPP project performance. Moreover, insights were provided on mechanisms that satisfy private investor in case of specific risk factors investigated. The findings are therefore expected to guide private party in the preparation of concession contract package that minimizes investments risks and thereby attracting more private investors both from local and international environments. The findings of the study would also contribute to the body of information for documenting standard conditions of concession contract in Nigeria.
Originality/value
Studies on critical performance factors on PPP were extended by developing compensation mechanisms against the investment risks that impact private party’s cost.

Abstract
Purpose
The purpose of this study is to develop penalty measures against concessionaires’ defaults as a mechanism for protecting the interests of parties (public and private) in public–private partnership (PPP) contracts for enhancing project delivery.
Design/methodology/approach
The research methodology is a mixed qualitative and quantitative approach. This study commenced with an in-depth literature review, which provided the basis for identification of penalty measures in construction contract management. The qualitative assessment was based on semi-structured face-to-face interviews, which were aimed at identifying the underlying pattern of the penalty measures, and the quantitative assessment was based on a structured questionnaire. In both cases, respondents were stakeholders’ organizations that had been involved in PPP contracts in the southwestern region of Nigeria. These include industrial practitioners from government-based organizations (ministries, agencies, corporations/parastatals, etc.), private developers/concessionaires, law firms, banks, etc. The sample size was selected using a respondent-driven sampling approach, as the comprehensive lists of the participants in PPP contracts are not readily available in the Nigerian construction industry. Responses from the interview were analysed using interpretative phenomenal analysis via ATLAS.ti7. The quantitative data were analysed using percentile for flexibility between “most” and “more” preferred mechanisms.
Findings
This study developed mechanisms that defined the rights of the public party to redress underperformance of PPP contracts consequent to the defaults of the private party. “Step-in-right” and “termination of the contracts” were preferred against specific cases of “delayed execution”, “abandonment of the project”, “bankruptcy of the concessionaire” and “non-compliance with design and specifications”. With respect to “shortfall in performance against established dates”, the results converged on “monetary fine” and diverged on “step-in-right” and “termination of the contracts”.
Practical implications
The study contributes to literature on mechanisms for enforcing PPP project performance. Besides, defining rights and obligations of the parties in specific events of underperformance of the concessionaires in PPP contracts is a significant step towards the development of standard conditions of contract for managing PPP projects in which the model is being newly adopted.
Originality/value
Project management studies on PPP were extended by defining the liabilities that are consequent to the defaults of the private party and the mechanisms for their enforcement.

Abstract
Purpose
The purpose of this paper is to evaluate the measures practiced by public sector organizations (PSOs) to develop their capability and strength toward attaining the skills requirements for public-private partnership (PPP) program.
Design/methodology/approach
The study adopted a quantitative approach based on primary data obtained via questionnaire survey. The literature review provided the basis for identification of variables that were evaluated through structured questionnaire survey. The respondents were professionals in PSOs that have procured PPP projects in Southwestern Nigeria. These were sampled through the drawing of referral chain, involving respondents-driven sampling technique. The data collected were analyses using descriptive and inferential statistics.
Findings
The capability development measures of PSOs in PPP projects delivery clustered around five components: conventional practices, training and development, organizational practices, human capital enhancement and government-aided intervention. These five components of capability development measures are expected to be focused with adequate and equal interest and embraced by PSOs in countries with evolving PPP markets.
Social implications
The study provides implications for domestic human capital strengthening for enhanced infrastructure delivery in countries with evolving PPP markets.
Originality/value
This study contributes to the existing literature on capabilities improvement on PPP projects. This was achieved by providing empirical evidences with respect to human resource boost for enhanced performance of public sector organizations in their partnership with their private sector counterparts for PPP project success.

Abstract
Purpose
The purpose of this paper is to assess how gender influences stress response strategies among quantity surveyors in workplaces with a view to enhancing job performance.
Design/methodology/approach
Primary data were obtained through a survey, which utilised structured questionnaires administered to quantity surveyors in Lagos, Oyo and Ondo States in Nigeria. In total, 334 quantity surveyors in government establishments, consulting and construction firms were randomly sampled to survey male quantity surveyors, and a purposive sampling technique was used to collect data from female quantity surveyors. Data collected were analysed using percentile, using mean item score (MIS) and Mann–Whitney U test.
Findings
In total, 27 stress response strategies were identified in dealing with stressors in quantity surveyors’ workplaces. The results of the analysis revealed the level of usage of the stress response strategies with the highest being “seeking clarification with colleagues or superiors” achieving an MIS of 3.95, followed by “belonging to professional association” (MIS=3.67), and “opportunity to discuss with manager/supervisor” (MIS=3.66). The scoring of the level of usage of the stress response strategies (2.20<MIS<3.95) suggested that although quantity surveying organisations were familiar with a good number of workplace stress response strategies, a significant number of the strategies were neither suitable nor adopted. Moreover, stress response strategies with high a rating of familiarity were also the most utilised and most effective.
Practical implications
The study provided implications for management roles in identifying stressors and appropriate strategies towards creating a healthy working environment and improving job productivity of female quantity surveyors in their workplaces.
Originality/value
The results show no significant difference in gender perception of the effectiveness of the 27 stress response strategies assessed except three. The first is “opportunity to discuss with manager/supervisor” with the Mann–Whitney U test (MWW) value of 3.337 at p=0.001. The other two are “prioritizing future workloads” (MWW=−3.226; p=0.002) and “clubbing or socializing” (MWW=−3.483; p=0.001). These findings imply that both male and female quantity surveyors perceived the use of these three stress response strategies in different ways. In this regard, although all the strategies may be applied as influenced by employers’ decision and preference, managers may have to exercise caution when applying them while dealing with male and female employees.

Abstract
Purpose
Anecdotal evidence indicates that there is a backlog in the pre-tertiary school infrastructure in the Eastern Cape Province of South Africa. The purpose of this paper is to assess the adoption of alternative building technologies (ABT) for pre-tertiary educational infrastructure delivery with a view to providing empirical evidence that could guide policy responses towards its wider adoption.
Design/methodology/approach
The study adopted a mixed methodology approach. This comprises a triangulation of a questionnaire survey and interviews. In total, 100 participants were randomly selected from 182 built environment professionals namely quantity surveyors, architects and engineers (electrical, mechanical, civil and structural) from the Department of Roads and Public Works (DRPW), who are currently involved in the Eastern Cape School Building Program (ECSBP). The questionnaire survey was supplemented by semi-structured interviews conducted with four top government officials (three from the Department of Education (DoE) and one from DRPW) who were also part of the questionnaire survey. Data collected were analyzed using descriptive statistics and phenomenological interpretation respectively.
Findings
The key findings showed that the level of adoption of ABT for pre-tertiary school infrastructure in the Eastern Cape province is primarily influenced and explained by perceptions that ABT offers inferior quality products compared to the conventional method, and limited awareness of its benefits.
Research limitations/implications
The study provides useful insights into the implications of the limited awareness of ABT as a an alternative technology for educational infrastructure delivery and policy responses towards its wider adoption and environmental sustainability.
Originality/value
Empirical evidence from this study indicates that the main motivation for the adoption of ABT is the limited government’s budget to cope with school infrastructural backlog, while environmental sustainability benefit is only secondary. Nonetheless, the realization that the backlogs in the provision of school infrastructure has resulted from sole reliance on the use of the conventional method is an indication of the potential that the adoption of ABT holds for minimizing of the backlog.
