Estudo de produtividade em canteiro de obra em edificações de parede de concreto

Abstract

The construction industry represents an important part of the Brazilian economy. According to the Brazilian Institute of Geography and Statistics – (IBGE), it is a significant player in the composition of PIB, representing an average of 6.2% in recente years. Given the importance that civil construction presents in the economic and social scenario in the country, development needs to be a priority and, for this, efficiency in the production processes needs to be improved. In this context the present work deals with how to determine productivity indices and what factors interfere in the production of molded concrete walls "in loco". The methodologies adopted for the appropriation of the data for the input and output models - Factor Models and the RUP - Unitary Ratio of Production, analyzed a building of molded concrete walls "in loco" in the city of Bagé/RS. The Factor Model seeks to know the factors that are linked to loss of productivity, while RUP quantifies production through the man-hour proportion and the service quantities related to the work day analyzed. After the data was gathered from the construction site, it was categorized and analyzed, and the influence of factors was observed such as: quality of the materials, climatic variation, workmanship, logistics of the construction site / equipment and lack of materials. Studying this data can provide invaluable information to aid in construction planning and management for the purpose of improving efficiencies in production processes.
