City integration

creating a large-scale building pit next to an existing residential building

 

A product modeling challenge

In a modern and vibrant city like Berlin, large-scale projects must be dealt with on a regular basis. Apart from the ususal stakeholders, a major project within a closely covered area additionally requires some effort concerning urban planning and management. To analyse the challanges and possiblities, an ontology and a parametric model of a mixed zone are developed. To do so, single models of a single family home, a story of an apartment building and a floor slab are integrated into one model describing a modern residential building. To represent a large-scale building project developing in the neighborhood, diaphragm walls are considered. These might be necessary in an area with hight levels of groundwater, such as Berlin.

The ontologies considered include an ontology describing the requirements towards a single family and a story of an apartment building. Those ontologies are assembled into one ontology and complemented by a classification for floor slabs in general. Finally, an ontology describing diaphragm walls is included.

An existing parametric model of the rooms making up a house is expanded by two models of floor slabs, each considering a different material. Additionally, the diaphragm walls are represented within a complete paramatric model.

Integrating the parametric models

The combined parametric model includes a model of a single-familiy home representing rooms and geometry, two different models of floor slabs and a representation of diaphragm walls.

Integrating the ontologies

Integrating the ontologies requires some greater effort, because many aspects are considered in severaly ontologies and in different ways.
