Integrating 5D Product Modelling to On-Site 3D Surveying of Bridges

In this paper a new process integrating 5D product modelling and 3D on-site surveying for bridge construction is presented. This enables faster and less error prone surveying session preparations, fluent communication of design plans between survey teams, design office and other parties related to the construction project. A prototype system based on a total station and Tekla Structures CAD software is defined, and implemented by programming a .NET add-on to Tekla Structures and tested in field tests in an actually bridge construction project. Tests indicate prototype as a viable tool for surveying, but it still needs further development in usability and measuring features. Results are applicable also to building and road construction surveying.
