A construction consortium is a true finite-life operating company. These are companies established to build some big project, and shut down when it's finished. The first big one was Six Companies, created to build Hoover Dam. Not just large consortia like that. At least in Canada, it's common that Foo Inc. will create Foo 1234 Main Street Inc. as a wholly-owned subsidiary to construct a single condo tower. I think it's a matter of limiting their liability (or at least keeping potential liabilities from one project from affecting other projects). A few years later once the construction is finished, the company is wound up.
