ECO EARTH SANDWICH CONSTRUCTION SYSTEM COST COMPARISON WITH CONFINED MASONRY, RAMMED EARTH, AND DRYWALL

Abstract:

Cost and environmental efficiency are high priority facts when developing a project for communities and clients in general, one way to have cost and environmental efficient construction systems, is by using local resources, materials, and manpower. The Con Lo Que Hay – With what is available 14 (CLQH 14) workshop, developed the eco earth sandwich system in a small suburban community center, in the Ecuadorian Andes, which uses local resources and manpower to lower cost production. The use of local resources also reduces the environmental impact, however, in this study we will focus on the evaluation of the cost efficiency of this alternative construction system with industrial drywall on metal studs, semi-industrial masonry with CMU block and mortar, and handcraft developed rammed earth with the option of hired manpower and with community labor. This comparison is developed to encourage local semiindustrial construction and demonstrate that it has cost efficiency advantages.
