Planejamento de obras de manutenção predial: estudo de caso em obras de impermeabilização nos municípios de João Pessoa e Cabedelo

Abstract

The maintenance of building systems is essential to ensure the durability and proper performance of constructions. In occupied buildings, these services face additional challenges, particularly due to their impact on residents' daily routines, such as noise, dust, and restricted access to common areas. In the case of waterproofing system maintenance using asphalt membrane, the demolition phase is especially critical. Considering the frequent rework observed in this type of project and the demand for speed and quality in the condominium sector, this study investigates the planning and execution of three building maintenance projects focused on asphalt membrane waterproofing, carried out in buildings located in the municipalities of João Pessoa and Cabedelo. The research analyzed the impacts of planning failures, with emphasis on rework, additional costs, and regulatory noncompliance. The main causes of problems were identified and the solutions adopted were evaluated, with the aim of proposing improvements to planning and management practices. Based on the logic of the Last Planner System, a learning table and a tailored Work Breakdown Structure (WBS) were developed for this type of project, incorporating the lessons learned from the case studies. The results show that a thorough preliminary inspection, combined with consistent initial planning and effective execution monitoring, are key factors in avoiding failures and ensuring the success of building maintenance projects, especially in sensitive contexts such as residential condominiums.
