What is described as a formal invitation to selected contractors to solicit bids for a project?

The term that accurately describes a formal invitation to selected contractors to solicit bids for a project is an "Invitation to bid." This process typically involves the owner or project manager inviting a specific group of contractors to submit their bids for construction services based on the project's specifications and requirements. This invitation ensures that only qualified contractors who meet particular criteria are considered, allowing for a competitive bidding process.

The "Invitation to negotiate" is less formal and is typically used in situations where the project owner wants to discuss terms with potential contractors rather than receiving formal bids.

A "Request for qualifications" is a document used to prequalify contractors based on their experience, past performance, financial stability, and ability to complete the project. This occurs before the bidding process to shortlist qualified candidates.

A "Request for proposals" invites contractors to submit proposals that include not only their bids but also methodologies, project approaches, and other qualitative factors. This is often used for more complex projects where the selection criteria go beyond price alone.

In summary, the "Invitation to bid" specifically targets the solicitation of competitive bids from contractors, which is the correct term for the formal bidding process.
