Analysis of quantities of work obtained through traditional construction methods versus BIM methodology

Abstract

Abstract

This article makes a comparison between two methodologies to obtain quantities in construction, a traditional approach versus the digital BIM (Building Information Modeling) technique. In this regard, scientific information was collected from digital repositories such as Redalyc, Scielo, Scopus, Google Scholar and the Ecuadorian laws and regulations used in consulting processes of construction were also studied. The data was obtained from projects designed using the BIM tool and analyzed using the traditional methodology. This information was evaluated and correlated. For this, two stages were considered, first the quantities in construction were quantified and then, in the second stage, were quantified the time used, the number of workers and their knowledge about the methods. Is concluded that the BIM methodology achieves greater accuracy and is faster in comparison to the traditional method, however it needs better trained professionals. Unfortunately, according to the laws of Ecuador the BIM methodology cannot be applied efficiently.
