ABSTRACT
The first BIM implementation in underground project in Poland was carried out by ASTALDI in the extension of Warsaw Metro (WM). The BIM uses in the design phase started from the 3D modelling of 2D design documentation, clash detection and quantity takeoff support. In the construction phase, the added value arose in the field of scheduling. The site activities were monitored by providing periodical model-based progress reports. The engineers had quick access to the BIM database via mobile and desktop devices. The project team used the laser scanning to enhance surveying and quality assurance. Methodical data collection, through all phases of the project within a single BIM database, greatly aided the development of the As-Built model that will be used in preparation of facility management tool. The BIM implementation in the WM project, allowed ASTALDI to better understand the cost-effective uses that information management provides for application in forthcoming projects.
