Does the preparation of the project feasibility study report of the integrated pipe corridor require bidding?

The preparation of the feasibility study report does not require bidding.

Because the feasibility study report is a study and analysis of the feasibility of a project in the planning stage, its content includes how to conduct bidding, and its role is to provide a theoretical basis for project establishment.

The tendering process begins after the project is approved.

To put it bluntly, the feasibility study report is for project establishment, before the project is established. The approval of the project means that the project is legal and can be implemented. At this time you can start bidding, signing contracts, designing drawings, etc. If the project cannot be approved and the project cannot be implemented, does bidding make sense?
