Análise comparativa entre o processo de orçamentação utilizando o Microsoft Excel e um software específico de uma obra de pequeno porte

Abstract

The construction budget is essential for forecasting costs and ensuring financial control in civil construction. This study compares the use of Microsoft Excel and software A, specifically designed for construction budgeting, in the budgeting of a small single-family residence, comparing the time taken to prepare the budget and the practical impacts on costs. The method consisted of preparing the budget using both tools, comparing the values obtained and the time spent on each platform, and the actual values and costs of the construction work, which has already been completed. The results indicate a difference of 9.19% between the costs budgeted by the two methods, with the Excel budget showing a deviation of only 2% from the actual cost of the construction, compared to 11% for the software A, and a difference in budget preparation time of 06 hours and 02 minutes. It can be concluded that, although there was a percentage difference between the tools, the financial impact on small-scale projects is limited. Nevertheless, Excel demonstrated greater accuracy, suggesting that its flexibility allows for fine adjustments in specific contexts, whereas the specialized software, despite being faster, may require more refined parameterization to increase its reliability.
