Proposta de Linha de Balanço no processo de projeto baseada na filosofia Lean: modelo para obras de pequeno porte.

Abstract

The construction industry stimulates highly diversified and contiguous sectors, both upstream and downstream of its integrated production chain, generating significant financial resources and contributing strongly to the national Gross Domestic Product (GDP). As a relevant macroeconomic indicator, construction should be understood as an essential sector for development, a constant target of technological innovations and continuous improvement. From the perspective of raising efficiency and productivity levels, new paradigms and production philosophies are emerging. Lean Construction, adapted from the principles of Lean Production, stands out as an innovative philosophy capable of mitigating the limitations of traditional project management models, which are often ineffective in the face of the increasing complexity, urgencies, and uncertainties inherent in the sector. Lean Production originates from the Toyota Production System (TPS), Consolidated in Japan in the 1950s, based on operational excellence, optimized use of resources, and systematic elimination of waste. Despite its roots in the automotive factory floor, the philosophy has expanded into civil construction. However, due to the high variability and distinct characteristics of mass production, adaptations of Lean principles to the particularities of construction were necessary. In this context, this work aims to analyze and propose the adaptation of more efficient and sustainable management methods. The joint application of the Lean Construction philosophy and the Line of Balance (LoB) tool is suggested, as these represent promising concepts for a productive approach, capable of reducing waste, maximizing value and meeting the demands of an increasingly dynamic market.
