    Public Private Partnership System Initiation Challenges for the Procurement of Public Infrastructure
    (Covenant Journal of Research in the Built Environment, 2024) Ojelabi, Rapheal; Oyenubi, Adebayo; Afolabi, Baruwa
    This study investigates the severity of the challenges associated with the Public-Private Partnership system initiation phase in the procurement of public infrastructure. Also, strategies for managing the barriers associated with the procurement system were evaluated. The study adopted a quantitative research method, conducting a questionnaire survey targeted at selected PPP stakeholders, which includes Architects, Builders, Structural engineers, estate managers, and Quantity surveyors in Lagos and Abuja. The stakeholders were elicited from selected 19 PPP projects using a project-based approach. The data generated were analysed with SPSS 21 using descriptive and inferential tools. Findings from the study revealed the most severe factors associated with PPP procurement system failure to deliver public infrastructure at the inception phase, including a lack of PPP development fund to promote PPP, corruption among the political class, and investors' perception of the country as high-risk for investment. Likewise, strategies considered significant to managing the PPP initiation barriers were unveiled including establishing policies to facilitate PPP at the inception phase, improving transparency in information sharing and providing guarantee legal framework to protect investors. The findings will grant PPP stakeholders insights to the issues responsible for the termination of PPP project collaboration at initiation phase of the procurement system. Also, the unveiling of the PPP challenges and mitigating strategies at the inception phase could guide stakeholders in developing a framework to a successful PPP implementation in a bid to encouraging more participation at this level.

    Government’s motives and investor’s commitment in public-private partnership procurement system adoption
    (Sciendo, 2025) Amusan, Lekan; Ojelabi, Rapheal Abiodun; Adewolu, Adeoye Olugbenga; Olanipekun, Oladeji Olubunmi
    The study examined the government’s motives - ment to infrastructure delivery. The study adopted a quan titative research method with a survey conducted using a structured questionnaire targeted at 384 respondents selected through random sampling. The data were ana lysed using mean, percentile and Pearson correlation sta tistical tools. The study identified 17 key motives respon sible for the government adopting PPP in socio-economic infrastructure delivery. These motives were factored into three main groups: public infrastructure maintenance, financial and economic benefits; improved discipline in the contractual relationship and predictable path in infra structure delivery and integration of innovative approach in enhancing infrastructure delivery. Therefore, the relationships between the three factored government’s motives and investor’s commitments, including finance, management, technical and operational services in PPP, were tested using the Pearson correlation statistical tool. The results showed that the motive for public infrastructure maintenance, financial and economic benefits of the government in PPP showed a significant relationship with the four services commitment of private partners. Also, the government’s motive for improved discipline in the contractual relationship and predictable path in infrastructure delivery showed significant relationships with technical, finance and management commit ments of investors. Lastly, the government’s motive for the integration of innovative approaches in enhancing infrastructure delivery showed a significant relationship with only technical commitment. The outcome indicates that factors measuring government motive and investor's services commitment are mutually dependent and critical in ensuring a sustained relationship among stakeholders in a PPP arrangement for infrastructure procurement.

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

    Practitioners’ experiences with the drivers and practices for implementing sustainable construction in Nigeria: a qualitative assessment
    (Emerald Publishing Limited, 2020) Tunji-Olayeni, Patience; Kajimo-Shakantu, Kahilu; Osunrayi, Ewaoluwa
    Purpose – The purpose of this study is to assess the drivers, practices and policies for implementing sustainable construction in Nigeria. This is with a view towards increasing the rate of implementation and diffusion of sustainable construction practice, so that more Nigerians can benefit from its environmental, social and economic dividends. Design/methodology/approach – This study adopted a qualitative research design with the use of face-to face oral interviews. Interviewees were selected using a purposive sampling technique. Data from the interview were analysed using thematic analysis. Descriptive statistics of frequencies, percentages and rankings were also used to present the data and complement the thematic analysis. Findings – The study identified five major drivers of sustainable construction: clients’ demand, international pressure, corporate social responsibility, competitiveness and cost-effectiveness. The common sustainable practices adopted by the interviewees are compliance with health and safety regulation, waste management, energy efficiency and material reuse. The most appropriate policies for implementing sustainable construction as suggested by the interviewees were government regulations, provision of tax relief and subsidies and public awareness. A combination of regulatory policies, market-based policies and voluntary participation of stakeholders will enhance the attainment of sustainability transformations in the construction industry Originality/value – The study is based on the findings of construction participants who have practical experience with sustainable construction in Nigeria. The study also provides empirical evidences which could guide the design and implementation of policies that will further promote the diffusion of sustainable construction in Nigeria.

    Evaluating Construction Project Performance: A Case of Construction SMEs in Lagos, Nigeria
    (IBIMA Publishing, 2016) Tunji-Olayeni, Patience; Mosaku, Timothy Olusoji; Fagbenle, Olabosipo Ishola; Omuh, Ignatius Owoicho; Joshua, Opeyemi
    Performance evaluation is a vital tool for assessing management performance and formulating corporate strategies. The Nigerian construction industry is reported to be very vibrant and one of the largest in Africa. It is made up of 78% indigenous firms and 22% foreign firms. The indigenous firms are predominately small and medium – sized. However, the Nigerian construction industry have been challenged to improve its performance because of reports of performance problems in terms of cost over runs, time over runs, poor quality of work, low productivity among other problems. The aim of the study was to establish the measures used by construction SMEs for evaluating performance. The study employed a case study research design. Five construction SMEs in Lagos, Nigeria were selected as case studies. The findings revealed that construction SMEs do not use any of the established performance measurement frameworks for evaluating performance. The main performance measures used by construction SMEs are cost, time, quality, customer satisfaction, profitability of the project, labour productivity, safety and team work. It was also established from the study that construction SMEs do not use supply chain management and employee satisfaction. It was suggested that construction SMEs should also use supply chain management and employee satisfaction because these measures have been found to impact positively on firms’ performance.
