This book shows the results of a study on the perception of the application of formal constructability tools and programs in housing construction projects by the personnel in charge of carrying them out, using an exploratory analysis as a basis for the study. The areas of opportunity for the application of constructability in housing construction projects are explored, proposing as a procedure to follow a non-probabilistic sampling through the application of a questionnaire to construction workers who develop different activities, to later establish a data base through the compilation of this information and to carry out a statistical analysis. As a result, it is observed that the tools and formal programs of constructability are not being used in most cases due to the lack of continuous and habitual application of them, influenced in many cases by the lack of knowledge of the real existence of these tools and programs and that only some of their principles of constructability are seen, but in an isolated manner.
