The chart identifies phase A as "Bidding or Negotiation." Bidding Documents are the comprehensive set of documents used to solicit bids from prospective contractors. This package includes bidding requirements, contract forms, conditions, specifications, drawings, and any addenda issued during the bidding period. While the core drawings and specifications are prepared during the preceding "Construction Documents" phase (B), the "Bidding or Negotiation" phase (A) is when the complete package is issued, used, and formally amended via addenda. Therefore, the Bidding or Negotiation process is fundamentally defined by the Bidding Documents.

B: This phase, "Construction Documents," focuses on producing the technical drawings and specifications, which are only a component of the complete Bidding Documents package.

C: This is the "Construction Contract Administration" phase. It commences after the contract is awarded and utilizes the Contract Documents, which supersede the Bidding Documents.
