Abstract. Data about building designs and layouts is becoming increasingly more readily available. In the near future, service personal (such as
maintenance staff or emergency rescue workers) arriving at a building site will have immediate real-time access to enormous amounts
of data relating to structural properties, utilities, materials, temperature, and so on. The critical problem for users is the taxing and
error prone task of interpreting such a large body of facts in order to extract salient information. This is necessary for comprehending
a situation and deciding on a plan of action, and is a particularly serious issue in time-critical and safety-critical activities such as
firefighting. Current unifying building models such as the Industry Foundation Classes (IFC), while being comprehensive, do not
directly provide data structures that focus on spatial reasoning and spatial modalities that are required for high-level analytical tasks.
The aim of the research presented in this paper is to provide computational tools for higher level querying and reasoning that shift the
cognitive burden of dealing with enormous amounts of data away from the user. The user can then spend more energy and time in
planning and decision making in order to accomplish the tasks at hand. We present an overview of our framework that provides users
with an enhanced model of "built-up space". In order to test our approach using realistic design data (in terms of both scale and the
nature of the building models) we describe how our system interfaces with IFC, and we conduct timing experiments to determine the
practicality of our approach. We discuss general computational approaches for deriving higher-level spatial modalities by focusing on
the example of route graphs. Finally, we present a firefighting scenario with alternative route graphs to motivate the application of our
framework.
