Factibilidad Económica para una Vivienda Rural de Interés Social en Materiales Alternativos Sostenibles, en el Municipio de Miraflores Boyacá.

Abstract

The shortage of adequate rural housing and the high costs associated with conventional construction systems represent a significant challenge for housing development in rural municipalities such as Miraflores, Boyacá. In this context, it becomes necessary to explore alternative construction methods that can reduce costs while maintaining structural safety and housing quality. The objective of this research is to evaluate the economic feasibility of a rural social housing model built with guadua and cemented bahareque as an alternative to traditional construction systems used in rural areas. The proposed design follows the guidelines established in the Colombian Seismic Resistant Building Code (NSR-10), particularly the provisions of Titles G and E, ensuring adequate structural safety conditions. The methodology is based on the application of the Work Breakdown Structure (WBS) to organize and manage project activities. In addition, Microsoft Project was used to develop the construction schedule, identify the critical path, and estimate execution times and costs. Based on this planning process, unit price analyses, cost estimates, and construction schedules were developed, enabling a comparative cost analysis between the proposed model and conventional construction systems. The results show an estimated reduction of approximately 25% to 30% in total construction costs compared to traditional methods, with an average cost per square meter ranging between COP $480,000 and $600,000. Furthermore, the financial evaluation through indicators such as Net Present Value (NPV) and Internal Rate of Return (IRR) produced positive results, indicating the economic feasibility of the proposed construction model. In conclusion, rural housing construction using guadua and cemented bahareque represents an Vivienda rural sostenible en Miraflores: factibilidad económica. economically viable alternative that contributes to reducing construction costs while promoting the use of locally available materials. This model can be replicated in similar rural contexts to support sustainable and efficient housing development projects.
