Comparativo de costos para unidad habitacional de 148.95 m2 ubicado en el sector de Nayón de la ciudad Quito, entre estructura de acero y mampostería estructural

Abstract

Determine the economic feasibility between steel structure and structural masonry for the construction of houses with an area of 148.95m2 for a housing complex located in Nayón, Quito, which will allow to establish the decrease the cost for the acquisition and promotion of the project. Steel has been used in buildings for its good mechanical properties, as well as for its speed in the construction process, saving sections and construction time; likewise, the use of structural masonry has been used in buildings of up to four stories, maintaining the structural characteristics of safety and durability, reducing the costs of material. Based on these structural systems, it is necessary to define which one generates lower costs for the construction, reducing the sale price and at the same time generating the highest profitability. Previously, the following information must be available: - Architectural plans of the project - Soil study of the project site. - Structural designs in steel and structural masonry. - Electrical and sanitary design. To define feasibility, the following information will be obtained: - Work volumes (geometries, weights and quantities). - Unit prices: cost of equipment, materials, labor and performance and quantity associated with each of the items. Define the indirect costs. Critical route: according to the construction sequence, establish the construction time of a housing unit and determine the critical route.
