Resumo
The construction industry in Brazil undergoes transformations due to the constant search of the
companies by space in this market. With a more demanding consumer and a significant range of
products on the market, the construction companies invest in efforts to increase the quality of
delivered products and reduce waste. The use of techniques developed in principle for
manufacturing may be an attempt to increase labor productivity, reduce waste and increase the
quality of the delivered product. Kaizen Costing is a cost management system that has the function
of maintaining the project's target cost and systematically implementing ways to reduce it. The
general objective of this work is to propose guidelines based on the Kaizen Cost to improve the
productive cycle of housing. For the proposal of guidelines, the research also sought to study the
current and viable productivity of the teams through statistical analysis, to build scenarios of
process optimization through computational simulation and to compare the production costs of the
optimization scenarios. The research strategy chosen was the case study, which was carried out in
an enterprise of repetitive housing units. The philosophy of the lean thinking was used to help the
understanding of production times and the use of the concept of future state studies. From the labor
productivity study, it was possible to quantitatively estimate the improvements for a new team
pace. The computational simulation allowed to analyze the improvements in the productive system
and to assist in the generation of a new cost of production considering the chosen services: internal
and external coating in mortar and subfloor. The results point to improvements related to the
adjustment of the discontinuities practiced in the planning of the work and balance of performance
between the teams. The changes made, if applied, allow a reduction of the cost of production of up
to 54%, maintaining the same quality standards in the final product.
