Ejecución de la construcción del reforzamiento del edificio del centro comercial Plaza Wong

Abstract

This final graduation project entitled "Implementation of the construction of the reinforcement of the building of the Plaza Wong shopping center" is an informative document about the construction process necessary to carry out the reinforcement, both columns and foundations, of a work not only unfinished But defective. The objective of this professional practice is the coordination, execution and supervision of the reinforcement of the building. From the review of the initial state of the construction it is clear that four global activities are required: excavation of columns, foundation, and reinforcement of columns and elaboration of subfloor. This required a daily field inspection, as well as gathering information on the materials and equipment of each task. Control of the cost and duration of the activities was carried out, as well as to identify the risks and how to mitigate them. All in order that the final implementation result fully complies with the new structural design, which does comply with the requirements of the Costa Rican seismic code and soil conditions As a result, a detailed description of the building reinforcement process is shown. The reinforcement lasted 115 days and a total cost of 80.027.488 colones, including materials, machinery and labor. The resulting cost is not the least possible. In addition to several drawbacks during the activities, other factors such as a late soil study affect the final cost. It is for this reason that the documentation of the contingencies and their solutions are of great help to future constructions that require a process similar to the one described in this document.
