Resumen

The research verifies the waste generated in the construction works of buildings at the National University of the Altiplano in Puno-Peru. The objective is to identify the construction processes involved in developing material waste produced at work, evaluate the types of waste they create, and determine the percentage of waste generated, assessing the excess or tolerance within the limits expected of construction losses. The results indicate that in the evaluated projects, waste represents, on average, 28.87% of the total cost of the progress executed. Wood waste represents more than 30% of the total; even in a study sample, it exceeds 90% of the total waste generated. Likewise, the construction process of formwork and stripping of structural elements affects waste generation by more than 50% in all the samples evaluated. This brings the problem of an additional cost for the disposal of this material, which accumulates in the construction fields. It proposes an alternative that reduces waste, focusing mainly on waste resulting from the wooden formwork system.
