Análise comparativa orçamentária usando preços locais e do SINAPI: um estudo de caso.

Abstract

The assertive preparation of a budget is of paramount importance for the proper execution of a work, with this, it is possible to predict the investment necessary for the execution of the project and assists in good financial planning. The National System of Research of Costs and Indexes of Civil Construction - SINAPI is a tool widely used, mainly by the Public Administration, where it is possible to find values ​​for manpower, inputs and equipment necessary to carry out engineering works. This work seeks to analyze the budget of an average standard residence in the municipality of São José do Sabugi - PB, comparing the price base of SINAPI and the local market. With the budget based on SINAPI prices, the analytical budget was dismembered, with this, all the necessary inputs and labor were defined. Soon after, market prices were collected, then the total budget amount was defined. Finally, it was possible to compare the two budgets. It was observed that the local budget presented a value of 4% less than the SINAPI budget. Although the percentage difference is low, there are some services that have become more expensive on site, such as electrical installations, while others are cheaper, such as plumbing and sanitary installations. It is concluded that it is important to verify the budget according to the reality of the region where the execution of the work is planned, since several factors can impact the value of an input, especially in the matter of being commonly used in the region or no, but also the location in relation to the suppliers of the inputs and, mainly, which services should have more attention at the time of purchase and execution, so that future losses are avoided.
