Estudo comparativo entre os sistemas SINAPI e TCPO no orçamento de uma edificação residencial unifamiliar popular

Abstract

The budget seeks to previously and effectively define the final price of an enterprise, specifying the items and services that comprise it qualitatively and quantitatively. TCPO – Price Composition Table for Budgets has been the most traditional source in the area for many years. SINAPI is the reference base for cost composition used by public bodies throughout Brazil. The two cost bases have different labor consumption and productivity rates, and making a cost comparison between these reference bases is relevant to be able to observe the results derived from this comparison. Thus, the work has as a general objective the comparison of costs using the two databases to evaluate the results. To carry out this comparison, a budget prepared by Caixa Econômica Federal was used based on a project for a popular single-family residence of 36.84 m² and a budget spreadsheet describing the services and the quantities. The research methodology was carried out through the use of databases from TCPO – Editora Pini, and SINAPI – Caixa Econômica Federal, to select the compositions and search for services, inputs and labor for each stage presented in the budget. The necessary adaptations and conversions were carried out in each service analyzed. The results indicate cost similarities between the two budgets carried out, but with some considerable variations in some stages of the budget.
