Método de evaluación de contratistas de obras civiles en licitación pública de precio unitario mediante indicadores de desempeño para supervisores en la etapa de liquidación

Abstract

In Colombia, public procurement of civil works through open bidding faces significant shortcomings in assessing contractors' performance, often resulting in incomplete projects and cost overruns. This study proposes a performance evaluation method to be applied during the contract liquidation phase, based on quantitative technical and administrative indicators, specifically designed for unit-price contract types. The research follows a qualitative-applied approach and is structured in four stages: documentary review, formulation of indicators, design of the evaluation instrument, and development of a methodological guide with digital support. The outcome is a replicable tool that enables contract supervisors to objectively assess contractor performance, thereby strengthening transparency, traceability, and efficiency in public infrastructure contracting processes.
