When dealing with the topic discussed here about the essential requirements in a public tender, we are obliged to touch on any powers in the administrative sphere, even those that require access to goods and services to provide good jobs to citizens, who have their own rights and obligations that the law constitutes and guarantees must be fully exercised. Public administration must always aim at the service of the collective interest and, by law, must manage public funds effi ciently. Knowing that your mismanagement can lead to penalties provided by law. Thus, the principles that govern the administration of public administration must be strictly observed, either in the provisions of Law No. 8.666/93 of the Federal Constitution, or in any other legal provisions, essential to the exercise of public administration, especially when it concerns the of bidding. It soon became clear that the objective of a clear and concise public tender was to allow the process of contracting works, services, purchases and assignments to be conducted democratically and fairly throughout the entire process. This allows the State to spend and allocate public resources in the most benefi cial way for the public administration.
