Currently, a lack of planning by public entities is identified in the works carried out in the country, which has resulted in incidents such as overruns, delays in the delivery of works, declaring the contract deserted and a nullity is generated. Thus, the public work and its importance are addressed, to later analyze the main actions by which the principle of planning in the public works contracts is violated and, finally, to elaborate the proposals of development in view of the infractions identified in the different inconveniences described. The methodology used for the preparation of this research was qualitative, integrating the documentary review of judgments, decrees and laws that allowed the analysis of the violation in the contracts, and thus arrive to a reflection of a proposed type that describes the possibility of mitigating the impact on contracting focused on the risk and general interest. This article originates from the concern about the effects of the lack of the principle of planning in the public contract for public works, for which purpose the legal nature of the principle of planning in public works contracts, its importance, the main actions for which it is violated and the proposals against these violations are established as purposes. The final answer that was obtained is the need, by public entities, for adequate preliminary studies to be carried out, and thus avoid overruns in the work to be performed. Similarly, it is important that predictable and quantifiable risk are verified, and thus protect the general interest.
