Abstract
The paper introduces and discusses bridge engineering, design and construction R&D results in a Finnish bridge cluster consortium (5D-Bridge). Development of national bridge information modelling guideline in Finland is introduced, as well as latest developments in 3D modelling in practice. A library of frequently used bridge components was developed to the use of the Finnish bridge cluster. Also the latest developments in integrating the information model with surveying and machine control is discussed. Results vary from success utilizing new tools to model concrete bridges and rebars in Tekla Structures and relative success through iteration regarding bridge blueprint production in actual bridge modelling and construction project, and the relative failures of creating and maintaining a national custom bridge components library for different CAD softwares. Machine control applications for bridge construction, such as excavating the foundations and piling are still tested mostly in limited pilots or simulations and waiting to be actually used in real bridge construction sites. Overall, the transition to using 3D information models for bridge construction projects is clearly inevitable as more and more bridge projects are being designed via information modelling.
