Estudo de caso: principais causas no desvio de prazo de uma obra vertical na cidade de Goiânia, Goiás

Abstract

This study aimed to identify the main causes of delays in a high-rise construction project in the city of Goiânia, with the purpose of proposing improvements in planning and control processes. The research addressed factors that directly affect schedule compliance, such as logistical failures, design changes during execution, adverse weather conditions, communication deficiencies among teams, and poor resource management — including shortages of materials and qualified labor. The methodology combined both quantitative and qualitative analyses through the collection of data from construction projects carried out over the course of one year. Spreadsheets were organized to calculate indicators such as the Percent Plan Complete (PPC), in addition to conducting interviews and field observations in order to understand, from a practical perspective, the challenges faced on construction sites. The results revealed the most frequent planning and execution failures and allowed the proposal of feasible solutions to mitigate these problems. Therefore, this study contributes directly to improving time and resource management in the construction industry, promoting more realistic schedules, reducing delays, and increasing the efficiency of project delivery.
