SUSTAINABILITY STRATEGIES IN ENGINEERING INFRASTRUCTURE IN DEVELOPING COUNTRIES; A CASE STUDY OF SELECTED SOUTH WESTERN REGION OF NIGERIA
Background of Study
Sustainability issue in recent times has dominated the arena of discussion in built environment. Billions of dollars’ worth of building investment are being initiated world over while little emphasis is placed on the aspect of maintenance of such infrastructure, this however could result into building an unsustainable building. In the tropic, careful consideration is often given to planning while proactive thought is not often according the maintenance aspect, this however is common to the public utilities and infrastructure. Most sectors, unfortunately, are yet to give issue of sustainable design and building, an appropriate emphasis, buildings meant for human habitation are developed without much emphasis on design concept, space ergonomics, construction process, renewable material and post construction post occupancy requirement. It is however pertinent at this juncture to appreciate the component of a sustainable building and infrastructure. Sustainable building are those that through their design, spatial orientation, choice of building components, construction and operational strategy, are highly efficient, also have low operating costs, environmentally friendly, and do not affect the health of their users and occupants negatively Solomon (2005)
An infrastructure that contains structure and form that are not sustainable can be describe as high and this has become a phenomenon in the tropic, it is high time however that paradigm should shift from non-sustainable development to sustainable one, through proactive strategy which this study aimed to achieve. The sustainability strategies chosen to provide an asset was used to effectively solve the erstwhile time, cost and quality paradigm (highest quality, at lowest price, in shortest time) which has now been overtaken by the value for money paradigm (Hackett, Robinson, Statham, & Langdon, 2007). The selection of the most suitable procurement method is critical for both the clients and the projects participants (Ibrahim, 2008).
