Testing 3D Building Modelling Framework In Building Renovation

Abstract

The paper describes a process where digital measuring survey data is transferred into 3D building model to be used as a foundation for renovation design. The process and method is tested in a case study of an office building of 8 floors. Measuring survey data is more often documented to 2D plan drawings, whereas 3D-modelling was more preferable in the case project. The final aim of the case project is to further test building product model or building information model (BIM) based design methods in building renovation. Product modelling is one emerging framework to manage building related information in contemporary design & construction. Model based methods are more commonly used in new buildings, whereas renovation is usually done with more traditional techniques. Case project results underline the importance of measuring and modelling definition phase. Measuring and documenting objectives for 3D-model based design work are different than for traditional design work. Measuring survey has to be done under the coordination of the designer participants. Selecting and informing the proper and capable surveying partners is also important.
