Macro-engineering
open-in-new
<p>In <a href="/facts/Engineering/RFVg8H3I">engineering</a>, macro-engineering (alternatively known as mega engineering) is the implementation of large-scale design projects. It can be seen as a branch of <a href="/facts/Civil_engineering/avh5kEq2">civil engineering</a> or <a href="/facts/Structural_engineering/Wj1vpoGh">structural engineering</a> applied on a large <a href="/facts/Landmass/Nr31Cq7A">landmass</a>. In particular, macro-engineering is the process of marshaling and managing of resources and technology on a large scale to carry out complex tasks that last over a long period. In contrast to conventional engineering projects, macro-engineering projects (called macro-projects or mega-projects) are <a href="/facts/Multidisciplinary/HP0uaNUs">multidisciplinary</a>, involving collaboration from all fields of study. Because of the size of macro-projects they are usually international. </p><p>Macro-engineering is an evolving field that has only recently started to receive attention. Because we routinely deal with challenges that are multinational in scope, such as <a href="/facts/Global_warming/rEN4BDE7">global warming</a> and <a href="/facts/Pollution/JRagxumQ">pollution</a>, macro-engineering is emerging as a transcendent solution to worldwide problems. </p><p>Macro-engineering is distinct from <a href="/facts/Megascale_engineering/UTahCsLT">Megascale engineering</a> due to the scales where they are applied. Where macro-engineering is currently practical, mega-scale engineering is still within the domain of <a href="/facts/Speculative_fiction/j9dUbo0d">speculative fiction</a> because it deals with projects on a planetary or stellar scale. </p>
