Achieving sustainable construction within Private Finance Initiative (PFI) road projects in the UK

The construction industry is facing the challenge of increasing demands of its sustainability performance. The construction and maintenance of the built environment has substantial impact on the sustainability of the environment. Whist, public sector clients are increasingly asking for a sustainable approach in their specification and procurement decisions, sustainability is still seen as a novel concept within the construction industry in many parts of the world without a settled definition. The premise of this study is that the interaction between road projects realized by the private finance initiative and their delivery in the UK improve sustainability. The paper, based on case study research, explains the sustainability implementation in a PFI road project and demonstrates that the PFI mechanism facilitates sustainable implementation to a far greater extent than is achievable using traditional procurement methods

Culture in sustainable infrastructure

The high failure rate of infrastructures around the world is alarming, most especially when such failures constrain economic growth and development. In most cases, existing institutions or strategies designed to maintain and reproduce effective infrastructures in areas that lack them have been mostly unsuccessful, particularly in sub-Saharan Africa. A carefully conducted survey covering the six geopolitical zones in Nigeria confirms the low-level stability, supply, quality and maintenance of infrastructure and its services. Using the severity index in matrix order model developed in this study, major factors responsible for unsustainable infrastructure delivery and failures are identified. The paper further argues that these major factors are interrelated rather than being peculiar to Nigeria or sub-Saharan Africa. Suffice it to say that the effects of these problems are widespread and of global impact. However, what cuts across all the major factors responsible for unsustainable infrastructure delivery and high failure rates are gross institutional lapses. In view of the fact that sustainable infrastructure is essential for sustainable development, this paper emphasises the uniqueness of the recipients' cultures and values alongside the integration of indigenous communities and infrastructure users: from conceptualisation to delivery within the framework for institutional building and sustainable infrastructure provision

Who is Who in Knowledge Economy in Africa?

This study assesses the knowledge economy (KE) performance of lagging African countries vis-à-vis their frontier counterparts with regard to the four dimensions of the World Bank’s knowledge economy index (KEI). The empirical exercise is for the period 1996-2010. It consists of first establishing leading nations before suggesting policy initiatives that can be implemented by sampled countries depending on identified gaps that are provided with the sigma convergence estimation approach. The following are established frontier knowledge economy countries. (i) For the most part, North African countries are dominant in education. Tunisia is overwhelmingly dominant in 11 of the 15 years, followed by Libya which is a frontier country in two years while Cape Verde and Egypt lead in a single year each. (ii) With the exception of Morocco that is leading in the year 2009, Seychelles is overwhelmingly dominant in ICT. (iii) South Africa also indomitably leads in terms of innovation. (iv) While Botswana and Mauritius share dominance in institutional regime, economic incentives in terms of private domestic credit are most apparent in Angola (8 years), the Democratic Republic of Congo (3 years) and Tanzania, Sierra Leone and Malawi (each leading in one year)

De-marginalising the public in PPP projects through multi-stakeholders management

Various problems have been encountered on PPP initiatives around the world that have eventually led to PPP projects failures. Public opposition due to various factors has been reported as the main reason for failure in several instances. A significant number of these factors point to two interconnected aspects: definition of the principal project stakeholder (PPS) and the management of the principal project stakeholder (MPPS), as a multi-stakeholder. Current literature on the management of project stakeholders has focused on the implementation phase which involves the private sector while the public as the principal stakeholders remain marginalised. This paper focuses on the latter aspect and takes a critical look at the process of multi-stakeholder consultation and management in a PPP project environment. The paper advocates for a paradigm shift in PPP stakeholder management and provides a conceptual model for appropriate stakeholder management in PPP projects

Factors Facilitating Construction Industry Development

This paper reports on a study aimed at identifying the key factors associated with construction industry development worldwide, by using a grounded theory approach. This involved, firstly, the identification of 62 variables from earlier studies. A questionnaire survey was then used to elicit views of the current strength of each variable. The resulting data were factor analysed and a set of eight key factors obtained comprising: (1) Industry-led better practice and culture; (2) Financial resources and investor confidence; (3) Human skills and culture of transparency; (4) Government policies and strategies supporting construction business; (5) Research and Development for construction; (6) Self-reliant construction culture; (7) Institutional support; and (8) Supportive attitudes from Aid agencies. These appear to be relevant to both developed and developing countries
