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.

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.

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.

The study provides information that would be useful for developing countries with evolving PPP markets for enhanced project delivery.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Studies on critical performance factors on PPP were extended by developing compensation mechanisms against the investment risks that impact private party’s cost.

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.

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.

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.

The study provides implications for domestic human capital strengthening for enhanced infrastructure delivery in countries with evolving PPP markets.

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.

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.

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.

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”.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

This paper aims to determine the effect of the period of abandonment on the final cost and duration of resuscitated tertiary educational building projects as a basis for enhancing the performance metrics of the projects and improving the availability of facilities in tertiary institutions in Nigeria.

A structured questionnaire was administered on 47 professionals involved in the physical development of construction projects in Osun State public tertiary educational institutions to provide primary data for the study. Secondary data relating to initial and final costs, initial and final completion dates, dates of abandonment, period of abandonment, date of re-award, etc. were obtained from selected resuscitated projects. Data were analyzed using relative significance index and regression analysis.

The most significant effects of project abandonment were found to be disappointment of populace and over-stretching of existing facilities. The study showed a directly proportional and an exponential effect of period of abandonment on percentage cost overrun of resuscitated projects, which were represented by y_c = −329.755 + 19.545x and y_c = 6.1662e_0.0506x, respectively. A linear relationship between period of abandonment and percentage time overrun was represented by y_t = 0.467 + 0.816x.

The fact that the regression equations could not be validated because of paucity of data was identified as a limitation of this study.

This study adds to the body of knowledge on abandonment of building projects from a quantitative perspective. Findings have implications for guiding long-term infrastructure development plans in public tertiary educational institutions.

Maximum threshold at which abandoned projects may be resuscitated at an economic cost was established as 16 months. Findings further suggest that the economy of new construction would outweigh resuscitation of abandoned projects beyond this period.

This study examined factors influencing the organisational capabilities of the public sector for building information modelling (BIM) implementation in construction projects with a view to enhancing the performance of public sector projects.

The study adopted a quantitative descriptive analysis that was based on primary data. In total, 198 valid questionnaires obtained from construction professionals within the public sector provided primary quantitative data for the assessment. The respondents provided the responses on the factors which were identified through an in-depth synthesis of literature relating to organisational capabilities of the public sector. Data collected were analysed using descriptive and inferential statistics.

The findings established that the potential of the public sector to deploy BIM in construction projects is greatly influenced by varying degree of organisational capability attributes with bureaucratic culture (mean score, MS = 3.37), structural complexity (MS = 3.17), lack of skilled and trained staff (MS = 3.12), personnel stability (MS = 3.11), staff cooperation (MS = 3.09) and political constraint (MS = 3.07) ranked highest. Through factor analysis, these and other highly influential factors were grouped into eight components, namely management-related, policy-related, technical-related, attitude-related, work structure-related, work ethic-related, decision-related and feedback-related factors. This grouping reflects the various components of organisational capability attributes which the public sector needs to efficiently develop to benefit from project management paradigm introduced by BIM.

This study provided information for improving specific capability attributes with respect to human and technical resources as well as other soft infrastructure to support BIM implementation on building projects by the public sector client. The study also serves as a guide for understanding BIM implementation by the public sector in similar socio-political and economic contexts.

This assessment indicates various degrees by which the organisational attributes of public sector have influenced the attributes' capability to implement BIM on construction projects. Thus, findings provide information on areas of improvement for better implementation of BIM by the public sector in project delivery.
