Construction bidding is a process where contractors, subcontractors, and suppliers put forward their quotes for upcoming construction projects. To describe the same process, we can also use the terms like tendering, proposal, or request for proposal. In the construction industry, construction bidding is also known as a bidding process, a formal request for bid, or a sealed bid process. Other synonyms for construction bidding include the words call to bid, bid invitation, and bid solicitation. The different terms used for construction bidding might vary from country to country as well. But, in general, they all describe the process of selecting a contractor, evaluating the bids, and awarding the project to the winner.
