Most architects, I believe, define the terms furnish (or supply), install, and provide, and sometimes those definitions appear in an owner's general conditions. When defined, they are part of the contract documents, and requirements using them are enforceable based on those definitions. In practice, perhaps because the definitions are nearly ubiquitous, I have had few problems with interpretation by contractors, or with enforcement.Oddly, it's architects who seem to have the most trouble understanding and using these definitions, even though the definitions originate in the architect's own office.
