Nguyen, T-H (1999) Automated deduction of topological information in a computer-based building design system. PhD thesis, Pennsylvania State University, USA.
Abstract
Constructed facilities or buildings are comprised of many components whose physical properties are usually represented in product data models by their spatial information including three dimensional (3D) geometric and topological information. Geometric data describes the building components' dimensions and locations, whereas topological data represents information about spatial relationships (e.g. connectivity, adjacency, containment, etc.) between the building components. Conventionally, the spatial information is modeled directly in product building data models to support all various aspects in building design. Due to the increasingly huge amount of building information to be modeled and the large variety of data representations needed to suit requirements of different professionals involved, the explicit modeling of topological information becomes an important challenge and is usually subject to data inconsistency, incompleteness, and prone to error. Recently, the emergence of advanced Computer-Aided Design (CAD) systems such as 3D solid modelers has offered possibilities to deduce the topological information from the positioning of geometrical solids, which are inherently available in the 3D CAD systems for representation of physical building components. This dissertation presents a computer-based building design framework with emphasis on the engine capable of automatically deducing topological information of building components to support various aspects in building design such as constructability analysis, construction planning, and building code compliance checking. This framework employs the concept of boundary representation (B-rep) in solid modeling for representing 3D building components enabling extraction of geometric and topological data necessary for deduction of spatial relationships between the building components.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
