INFLUENCIA DE LA CLIMATOLOGÍA EN LA PRODUCTIVIDAD Y DURACIÓN DE LOS PROYECTOS DE CONSTRUCCIÓN. CASO DE ESTUDIO EN CHILE

Abstract

Constant exposure to adverse weather conditions in civil work projects generates, in most cases, unavoidable delays during the execution phase. Therefore, activity planning and time management at an early stage will always be advisable when estimating the future project duration. However, little research addressing has been made quantifying the productivity loss due to the effect of weather in construction works. To address this problem, a case study applied in Chile shows the project duration extension suffered on a series of six similar reinforced concrete bridge construction projects. This study, involves the application of a simple method based on climate performance reduction coefficients generated for each construction activity and show how the latter are influenced by weather. In addition, for the sake of clarity a series of isocurve maps depicting the expected average productivity loss are presented.
