Estudo da viabilidade técnica e econômica do método construtivo Light Steel Frame e alvenaria convencional

Abstract

The study evaluates the technical and economic feasibility of Light Steel Frame (LSF) and conventional masonry, two distinct construction methods. LSF, a modern and sustainable approach, stands out for its execution speed and waste reduction due to its dry construction process. Conventional masonry, widely used in Brazil, has a lower initial cost and good durability but generates more waste and demands more labor. The research shows that, although the initial cost of LSF is 20.94% higher, it reduces construction time by up to one-third compared to the conventional method. Additionally, it offers advantages such as more economical foundations, superior thermal and acoustic insulation, and reduced environmental impact. On the other hand, masonry, deeply rooted in Brazilian construction culture, faces challenges such as higher material waste and slower processes. The study concludes that, despite cultural and cost-related barriers, LSF is a promising alternative due to its sustainability and efficiency. Greater awareness among construction professionals is recommended to encourage its adoption in Brazil, fostering a transformation in construction methods and promoting more innovative and sustainable practices.
