Desvios de custo em empreendimentos da construção civil: um levantamento de fatores de influência para obras de pequeno porte

Abstract

Compliance with the budgeted cost is crucial for the success of civil construction work. However, it is still common for works to be completed over budget. Such problems can be even greater in Small Works, due to several factors, such as inefficient cost management or even being absent in works of this size. Thus, this work aimed to identify the main causes of cost deviation in Small Works. To this end, a survey was carried out with 158 construction professionals from different Brazilian states, in order to verify their perceptions about the causes of cost deviation in their works. For data analysis, Exploratory Factor Analysis (EFA) was used. Two samples were taken: the first with works of all sizes; another only with Small Porte Works. This made it possible to compare the ratios of cost overruns in medium and large-scale projects with those of small-scale ones. For the first sample, the cost deviation was associated with 4 factors: Construction Management, Central Administration, Projects, and Economic Environment. As for the second, the factors were: Construction Management, Economic Environment, Projects, and Labor. It can be concluded that there is a difference between the causes of cost deviation in medium and large works compared to small works.
