Diseño y desarrollo de un sistema gerencial de obras, aplicado al control de costos en la construcción.

Abstract

This present project comes up with the development of a software, to increase productivity in small and medium construction companies, applying the Lean philosophy and using a client-server architecture, using Visual Basic.net / MySQL as programming language. The software development was made in order to optimize the flow chart of businesses, to do so, it started with a generic diagram of cost and quantity control commonly used by Ecuadorian companies. Once the diagram is obtained it proceeded with the Lean Principles guidelines to identify activities that do not generate value to the customer and replace them with automated processes obtaining greater availability of time devoted to work. Next, the SCC program is tested on the already built project of "Jardines de Ninallacta" entering a two month data stream to obtain reports such as: contractors’ payroll, comparison between estimates and actual spent money, scheduled compared with actual finish time, and partial and accumulated labor, material, tool and equipment, and total cost weekly or monthly charts. Finally, the present work proofs the versatility of the SCC compared with the rudimentary methodology used in the actual “Jardines de Ninallacta” construction project.
