In countries around the world, budgetary constraints mean that governments struggle to execute large scale and often capital intensive projects to bridge infrastructure gaps. Consequently, it has become the practice to involve the private sector in infrastructure development in order to ease the financial burden, step-down the risks inherent in carrying out infrastructure projects and expedite the provision of infrastructure. Involvement of the private sector can cover the gap, attract private financing and bring innovation, expertise, efficiency and sustainable development into infrastructure delivery.
