Estimativa automática de custos de construção para uma residência unifamiliar

Abstract

Given the current economic situation and the high competitiveness of the market, the strategic planning of civil construction work has become an essential service for its development as a whole. Methodologies such as Lean Construction are increasingly booming in construction companies across the country, as the organization has become an intrinsic factor, from project design to delivery of the residence to the final customer. Following this trend, a financial schedule is a tool that has stood out in the planning scenario, as with rising input prices, a profitable result and even the success of the construction company depend directly on this process. However, achieving maximum precision between the budgeted and actual executed costs is practically impossible, due to the various losses of inputs, reworks, and different levels of productivity of the companies' workforce. So, as it is a complex and at the same time subjective activity, a simple spreadsheet such as Microsoft Excel may not be enough, making companies resort to softwares such as OrçaFascio, which are based on cost reference models, such as SINAPI and several others, monopolizing the market for budgeting systems, however, through high annuity rates. Therefore, this work proposes the creation of an authorial program called OrçaBasic, which based on the VB.NET language in a WFA - Windows Form Application model, with appearance and functionalities similar to those of Windows applications, manages to simulate the cost of constructions, through a synthetic quote, free of charge.
