When a government, or sometimes a company, wants a particular project (such as a construction job) to be carried out by a contracting company, it often calls for tenders, or sealed offers naming a price to do the job. The competitors for the job must submit their tenders by a certain deadline, after which all are opened together, and typically the lowest tender wins the project.
