The conception, fabrication and installation of public artwork is always teamwork. Many kinds of competencies are needed and this requires the integration of the know-how of local enterprises and actors in the urban construction. It is also good to have in mind local history and respect of the natural environments (if they still exist) and their inhabitants.
A public sculpture/installation may be small and only visible for the most observant or it may function as a landmark that can be seen from far away, even from space. It may outlive its' creator for hundreds of years or just be there for one day...
