Comparative analysis between SINAPI's indexes and those adopted by the companies of the city of Manaus in the services of concrete production and frame

Abstract

In the present study, a comparative analysis between the SINAPI ́s indexes and those adopted by
companies of the city of Manaus-AM is presented, in the services of concrete production and frame.
The differences between the indexes and the economic impact caused by them were verified,
through budgetary simulation with data from State Secretariat of Infrastructure of Amazonas, where
was attested the viability of using the SINAPI values only to the inputs defined as materials, while
those referring to labor and equipment, according to this research, need greater care because they
present significant differences between the costs studied, safety, control and management,
communications, accessibility and the building's life cycle.
