Evaluación del proceso precontractual del proyecto: “construcción del poliducto Pascuales- Cuenca y sus estaciones”

Abstract

The evaluation of the pre-contractual process of the Pascuales - Cuenca Pipeline project is carried out due to anomalies in the budgeted costs. Initially, the project was budgeted at a cost of USD 272 million, was contracted at USD 369 million and was executed at a cost of more than USD 623 million. Today, the pipeline has technical and operational deficiencies that prevent it from reaching design capacity. The objective of this study is to analyze the data provided by Odebrecht construction company in the adjudication process. For this, firstly a unit price analysis (UPA) is performed on the most relevant items of civil works, obtained through the Pareto diagram. Then, a detail of the process is made for the percentage of indirect costs that affect the final budget of the work. Finally, a cost classification is met under the AACE system, which determines the degree of maturity of the project and the different particularities that occur in each analyzed item. The obtained results show that 80% of the civil works budget is concentrated in 13% of items, under the analysis of unit prices carried out with input data provided by different entities, there are significant differences of overestimate and under estimate cost. For the analysis of indirect costs, a base value of 22% is determined, which directly affects the increase in the project budget. For the classification provided by the AACE, it is determined that 62% of items are at a level of detail of less than 2% for the execution of the work. The obtained data in this analysis of unit prices, indirect costs and classification of items, show the over costs executed due to incorrect calculations, lack of technical specifications and detailed plans, bureaucratic costs and an extremely low level of maturity of the project for the beginning of the execution of the work. All these errors are currently seen in the operational and design problems that the pipeline, pumping stations and terminals are facing.
