Benefícios e barreiras no uso do PERT/CPMem projetos de construção civil

Abstract

The construction industry still faces barriers such as process inefficiencies, high levels of waste, and occupational safety shortcomings. In this context, the adoption of the PERT and CPM tools represents a relevant alternative to improve project planning and monitoring, highlighting their benefits and limitations in overcoming these challenges. Construction projects are known to face risks and delays due to factors such as poor management, scope changes, and weather conditions. Therefore, efficient project management is crucial to the success and sustainability of the sector, while proper planning is essential to prevent delays and additional costs. This research included a bibliometric analysis of studies related to these techniques and the application of a survey directed at civil engineers, aiming to analyze how the construction industry has adapted to the use of PERT and CPM. The data collected was analyzed in comparison with findings from the literature, allowing a discussion focused on the main difficulties and potentialities observed. The results indicated that professionals with greater expertise regarding the tools reported significant gains in project predictability and control, whereas less experienced respondents presented more dispersed perceptions. Furthermore, PERT and CPM stood out for their effectiveness in defining schedules, structuring activities logically, and mitigating risks. By summarizing the most relevant information regarding the use of these tools, this study provides practical insights for planners who consider adopting PERT and CPM in their projects, highlighting the main advantages and challenges identified through both bibliometric analysis and the survey applied to professionals who already use these methodologies in construction projects.
