Megaprojects

Abstract

“Megaprojects” is a term used to refer to projects and events that encompass large-scale projects in size, cost, space, time, energy, and influence. They are synonymous with large engineering projects, complex projects, large transport or energy projects, and large infrastructure projects, and are often composed of multilayered discrete projects forming a larger scale complex project. Some of the complexity deals with difficulty in quantifying the long-terms costs or benefits or fully realising the whole life cycle of the megaproject prior to commencement. Megaprojects are often shaped by contextual factors. Where complexity is related to technical aspects of the project it also includes organizational aspects and the scope of the project. Some of these projects are multifaceted and relate to science research, engineering infrastructure, or private and public construction of buildings and/or other venues. Megaprojects affect societies that undertake them, urban planning aspects, and social relationships between stakeholders engaged in executing all the elements involved in creating them. They have an impact on a number of areas both locally and globally. This includes extending notions of urban planning to accommodate large-scale construction. These projects can be significant in terms of social and/or economic factors in a positive or negative sense. There have been debates and criticism on the need and function of megaprojects and whether they are beneficial constructs or detrimental to society.
