Comparativo de produtividade entre SINAPI e serviços de contratação terceirizada, para execução de estacas escavadas mecanicamente – estudo de caso em residência de alto padrão em Maringá-PR

Abstract

The work in question is a case study in which a comparison was made between productivity coefficients provided by SINAPI and data measured during a foundation pile drilling service in the city of Maringá, Paraná. The object of study is extremely important for the elaboration of schedules because it is the method most used in the region for foundation due to the soil characteristics and because it is one of the first activities to be performed. The main objective of this study is the critical analysis to verify if there is discrepancy between the indexes and if the exclusive use of SINAPI is favorable for the elaboration of pile execution planning in construction schedules when it is not mandatory. The research will be based on the characterization of the job site and the service, then the on-site measurement of the drilling productivity in minutes, and finally, the analysis of the results. From the comparison, it was possible to conclude that there were divergences between the indexes, being the productive index 67% of the value given by SINAPI, and the global index 85%. The research indicates the need for a continuous study of the productivity of the contractor or the team assigned to the service in order to be aware of this variation and, with experience, to have a productivity index of their own.
