A Spatial Query Language enables the spatial analysis of Building Information Models and the extraction of partial models that fulfill certain spatial constraints. Among other features, the developed spatial query language includes topological operators, i.e. operators that reflect the topological relationships between 3D spatial objects. The paper presents(More)
In a current research project, our group is developing a 3D Spatial Query Language that enables the spatial analysis of Building Information Models and the extraction of partial models that fulfil certain spatial constraints. Among other features, the spatial language includes directional operators, i.e. operators that reflect the directional relationships(More)
This paper presents a novel methodology which assists in automating the generation of time schedules for bridge construction projects. The method is based on a simulation of construction works, taking into account the available resources and the interdependencies between individual tasks. The simulation is realized by means of a discrete-event simulation(More)
For the spatial design of buildings as well as for the layout of large event areas, the 9 crowd behaviour of the future users plays a significant role. The designing engineer has to make 10 sure that potentially critical situations, such as high densities in pedestrian crowds, are avoided in 11 order to guarantee the integrity, safety and comfort of the(More)
Existing pedestrian dynamics models differ in computational effort and their ability to authentically describe human movement behaviour. Hybrid approaches combine different models to speed up simulation time and to improve the results of the simulation. Current hybrid approaches can only combine a specific set of models. It is not possible to independently(More)
