Abstract In the globalized business world, construction companies start to seek new opportunities to invest on an international basis in order to gain profit. Therefore, construction companies have to conduct not only national projects but also international projects to be competitive. However, although these international projects can be profitable, the construction companies face many challenges in the management of these projects due to the country-specific problems and conditions. This can lead to variation in the management of similar projects conducted in different countries. In particular, cost estimation in different countries is a challenging task for construction companies. Therefore, in order to provide insights about construction cost in different countries, different organizations publish construction cost indices. However, some criticisms related to the reliability and usability of these indices are stated. In this study, a new concept, called a cost map, is proposed by developing a framework based on twelve macro level parameters. The cost map is applied to 37 European countries. The data related to these parameters are collected using different databases. European countries are clustered by using a self-organizing map. As a result of this study, the cost map is determined as a reliable and convenient tool for a cost comparison.

欧洲国家建设成本图

摘要 在全球化的商业世界中，建筑公司开始寻求新的国际投资机会以获取利润。因此，建筑公司不仅要开展国家项目，还要开展国际项目才能具有竞争力。然而，虽然这些国际项目可以盈利，但由于国家特定的问题和条件，建筑公司在这些项目的管理上面临着许多挑战。这可能导致在不同国家进行的类似项目的管理存在差异。特别是，不同国家的成本估算对建筑公司来说是一项具有挑战性的任务。因此，为了了解不同国家的建筑成本，不同的组织发布了建筑成本指数。然而，陈述了与这些指数的可靠性和可用性有关的一些批评。在这项研究中，通过开发基于十二个宏观层面参数的框架，提出了一个称为成本图的新概念。成本地图适用于 37 个欧洲国家。与这些参数相关的数据是使用不同的数据库收集的。欧洲国家使用自组织地图进行聚类。作为这项研究的结果，成本图被确定为一种可靠且方便的成本比较工具。欧洲国家使用自组织地图进行聚类。作为这项研究的结果，成本图被确定为一种可靠且方便的成本比较工具。欧洲国家使用自组织地图进行聚类。作为这项研究的结果，成本图被确定为一种可靠且方便的成本比较工具。
