The words usually pertain to sculpture that is conceived for, dependent on, and inseparable from the location where it is placed. Scale, size, and placement result from an analysis of the particular environmental components.Richard Serra, installation sculptor, said: "The concept of site-specific sculpture has nothing to do with opinion or belief. It is a concept which can be verified in each case. . .The evidence of the process can become part of the content. . .How the work alters the site is the issue, not the persona of the author." ("Art and Theory", Edited by Charles Harrison and Paul Wood).
