巴塞罗那一公用设施地道的实例研究表明,为了评估而考虑工程中所使用地下土地的价值的重要性,在所研究的实例中,已证明这一变量对工程的可行性是主要的决定因素。然而,在过去,地下土地的价值一贯被忽视,因此,在决定这类价值时没有确定的程序。本文建议对一已知区域确定隐含市场价格的实用程序,并将其应用于巴塞罗那公用设施地道工程的收益费用分析中。 An authentic case study of a utility in Barcelona shows that, for the sake of evaluation, the importance of the value of the subterranean land used in the project is considered. Among the examples studied, this variable has proved to be the main determinant of the feasibility of the project. However, in the past, the value of subterranean lands has always been ignored, so there is no definitive procedure for determining such values. This article proposes a utility for determining the implied market price for a known region and applies it to the analysis of the revenue costs of the tunnel utility project in Barcelona.
