Have subsidiaries and other corporate consortia won the bid for the parent company project?

No. In the bidding process, after a subsidiary or other consortium wins the bid, the parent company usually does not directly undertake the project, but the members of the subsidiary or consortium are responsible for the specific implementation. This is because in the consortium, each member company has its own responsibilities and shares the risks and responsibilities of the project. If the parent company wins the bid directly, it may violate the provisions of the bidding documents, and may also lead to conflicts of interest or other problems.
