Avaliação da influência da distância de transporte no preço de obras de pavimentação em paralelepípedo

Abstract

This study aimed to analyze the influence of the transportation distance of cobblestones on the final price of public paving works in the State of Piauí, Brazil. The research was motivated by the relevance of this type of pavement in the urban infrastructure of the state and by the high volume of investments allocated to such works in the regional context, as evidenced by Technical Note No. 01/2024 issued by the Court of Accounts of the State of Piauí, which required a more detailed technical assessment of the costs that compose these interventions. Data were obtained from budgets, projects, and cost calculation reports of cobblestone paving works made available on the TCE-PI Bidding Portal, considering contracts tendered after the publication of the aforementioned Technical Note. Only contracts in which stone transportation was budgeted through the transportation moment were analyzed, allowing the comparison between the adopted distances and the percentage representativeness of this service in the total contract value. Statistical analysis demonstrated a positive correlation between these variables, enabling the proposition of empirical reference equations that express the influence of distance on the transportation cost of cobblestones for the reality of the State of Piauí. It is concluded that transportation distance is a determining factor in the cost composition of cobblestone paving works.
