Determinação e análise do custo unitário básico da construção civil para residências unifamiliares do município de Delmiro Gouveia - AL

Abstract

The Basic Unit Cost (CUB) is a parameter that arose in order to contribute to the real estate market, but which has become a cost indicator in the Brazilian civil construction sector. Its determination and disclosure is mandatory in all States, and this function is assigned to the Trade Unions of the Civil Construction Industry (SINDUSCON) and normalized by NBR 12721/2006, which stipulates its calculation methodology and presents several standard projects to represent the different types of existing buildings. In order to obtain the value of the CUB, price surveys of the inputs that make up each standard project must be carried out with the builders or stores of construction materials within the state territory. The values found reflect the prices of each input collected in different regions applied to a weight assigned to it according to the construction pattern. In this way, we sought to determine and analyze the effective CUB of the municipality of Delmiro Gouveia and its relation with the CUB of the State of Alagoas, since we do not know the existence of studies related to this aspect. According to the provisions of the standard, the survey of the inputs of standard single-family designs of a pavement was carried out with local suppliers. The percentage of accumulated variation of the CUBs of the standard projects was calculated between two consecutive months. It was also demonstrated the participation of the items that make up the input families in the calculated CUB values. From the realization of this research it was confirmed a disparity between the values of the CUB's of the municipality and of Alagoas. The local Basic Unit Cost calculated for each standard project was lower than the state average during the study months.
