ABSTRACT
Brazil's construction sector is of great importance to the recovery of the GDP, negatively impacted due to the Covid-19 pandemic. This study presents two innovations that help transform this picture. One linked to the style of construction and architecture, the "open concept", and the other, a management philosophy that has conquered space in several organizations in the construction industry, Lean Construction. The objective of this work is to present and analyze a stage of a residential remodeling, managed through Lean Construction, using tools to support decision making and consequently process optimization. The methodology used consists of a case study, dealing with the analysis and decisions of a critical stage of the remodeling planning of the property, involving the demolition of three pillars, to make the open concept feasible. The change of scenery during the project encouraged the development of new actions that would allow the achievement of the objectives without jeopardizing the remodeling schedule, bringing security to the clients. The positive results achieved corroborate the importance of applying Lean Construction, its principles and tools for contributions in the planning and development of projects in the civil construction sector.
