Abstract
The World energy council (WEC) of which Nigeria is a member share a common belief that guaranteeing a sustainable supply of affordable energy is one of the best ways to address poverty, inequality and environmental degradation everywhere on the plant. So many natural gas pipeline projects exist at different implementation stages in Nigeria and many of its projects have struggled to achieve sustainability throughout their lifecycle. Specifically, natural gas pipeline construction projects have neglected to consider economic, environmental, and social factors, resulting in inefficiencies and a continued lack of energy access in the country. This research focused on examining the relationship between project life cycle costing and the sustainability of natural gas pipeline construction projects in Nigeria. The study employed literature reviews, document analysis, and case studies, employing both descriptive and explanatory research designs. Nigerian gas pipelines used for power generation, cement production, and other purposes served as the case study. The findings revealed that initial costs significantly influenced the sustainability of natural gas pipeline construction projects. Additionally, maintenance costs and end-life costs were found to impact the sustainability of such projects in the Niger Delta region. Moreover, the research demonstrated that operational costs played a crucial role in explaining natural gas pipeline construction projects in the Niger Delta.
