Abstract
Las obras públicas en el Perú comúnmente son desarrolladas bajo el sistema de
contrataciones a Suma Alzada, en el cual, el postor ofertará un monto fijo por el
total de trabajos a realizarse. Se trata de un precio invariable que se define en
base a las cantidades, magnitudes y/o calidades que la Entidad indique
previamente.
Así, aunque la figura del Suma Alzada pueda parecer fácil de entender y aplicar,
con cada vez más frecuencia se advierten controversias durante la ejecución
contractual en las cuales, el Contratista solicita ampliaciones de plazo, costos
directos, mayores gastos, entre otros, pues surgen situaciones no contempladas
en la oferta. Tal problemática, a nuestro punto de vista, tiene su génesis en la
limitada e inexacta información que la Entidad entrega a los postores, situación
que lleva a estos últimos a ofertar un monto equivocado, que no refleja la realidad
de los trabajos a realizarse.
En ese orden de ideas, el presente trabajo plantea la problemática en torno al
sistema de Suma Alzada cuando la información entregada resulta insuficiente,
así como presentar los problemas contractuales que comúnmente surgen de
esta.
Public works in Peru are commonly developed under the Lump Sum contracting system, in which the bidder offers a fixed amount for the total work to be carried out. This represents a non-variable price defined based on the quantities, magnitudes, and/or qualities previously indicated by the contracting entity. Thus, although the Lump Sum system may appear straightforward to understand and apply, increasingly frequent disputes arise during the execution of the contract. In these cases, the contractor requests extensions of time, direct costs, additional expenses, among others, due to unforeseen circumstances not contemplated in the original offer. In our view, this issue stems from the limited and inaccurate information provided by the contracting entity to the bidders, which leads them to submit an incorrect proposal that does not reflect the actual scope of work to be performed. In this regard, the present paper addresses the issues related to the Lump Sum system when the information provided is insufficient, and also examines the contractual problems that commonly arise from such a situation.
