In this paper we suggest an extension to the Industry Foundation Classes model to integrate point cloud datasets. The proposal includes a schema extension to the core model allowing the storage of points either as Cartesian coordinates, points in parametric space of a surface associated with a building element or as discrete height fields projected as grids onto (building element) surfaces. To
handle considerable amounts of data, we further suggest to employ the Hierarchical Data Format (HDF) as an efficient serialization format as an additional alternative to clear text encoded ISO 10303 part 21 files. Based on prototypical implementations we show early results of population files and discuss potential benefits of dedicated compression algorithms.
