Company or partnership or joint venture or consortium submitting a bid. To be distinguished from “successful bidder,” which is the winner (a.k.a. contractor). This distinction can clarify whether work noted in the draft contract (for example, submission of a plan) is a misplaced part of the response instructions (and, therefore, refers to something to be submitted with the proposal), or part of the SOW (and, therefore, to be submitted after contract award). See proponent.
