Determinación del tiempo improductivo “Making do” y su relación con la pérdida económica en obras de Ingeniería Civil
There are different situations that generate unproductive times in Civil Engineering works, the purpose of this research is to publish about a new type of loss by flows, called Making do or “hacer por hacer”, this type of waste appears when an activity is carried out without considering all the resources that intercede for the development of this activity is carried out, that is, it is the product of poor planning.

This document has been based on the research carried out by Carlos Formoso in 2011, where he proposes a method to measure it, as well as to know its causes and possible impacts, in this way it was recorded daily the events that generate Making do through a data collection form, the study was focused on Irrigation Engineering works and drinking water, since eventually studies are carried out dedicated to building and housing works.

The results obtained show that there is a percentage due to Making do under construction and is directly related to the economic loss, however, it is minimal, but neglecting that loss could increase, causing losses for the company. The best thing then will be to know about the Making do and find a way to eradicate it from the construction industry.
