Financial planning and cost control as determining factors for efficiency in civil construction

Abstract

Construction projects are subject to technical, financial, and organizational constraints that make predictability a central asset for project performance. In this context, even technically consistent undertakings may lose efficiency when they lack adequate financial planning, reliable cost estimation, cost-schedule integration, and continuous monitoring mechanisms. This article analyzes the roles of financial planning and cost control as determinants of construction efficiency, considering how budgeting, contingency, cash flow, physical scheduling, and managerial control interact throughout the project cycle. This is a qualitative, exploratory, and descriptive study based on a systematic literature review and documentary analysis. The corpus included international literature on construction cost management, Brazilian technical and institutional references, and national studies on production planning and control in construction projects. The findings indicate that economic-financial efficiency does not result from mere cost-cutting, but from the ability to structure budgets based on feasible quantities and assumptions, incorporate contingencies compatible with project uncertainty, integrate cost and time, monitor deviations, and act on their causes. It is concluded that financial planning and cost control are not secondary tasks, but structural dimensions of sound engineering and efficient management, playing a decisive role in reducing waste, preventing delays, rationalizing resource allocation, and increasing project reliability.
