Bradley, P E (2019) Methodology for the sequence analysis of building stocks. Building Research & Information, 47(2), pp. 141-155. ISSN 0961-3218
Abstract
A new methodology is presented for analyzing longitudinal building data by considering building histories as sequences of states or events. This allows for the application of sequence analysis methods to any kind of building histories. A demonstration of this methodology is applied to two example datasets from a random sample of a stock of vanished buildings based on the records of a German building insurance company over a period of 56 years. In this sample, the diversity of the distribution of states increases with a slight fall near the end of the time period. Non-residential buildings remain longer in a given state than residential buildings, and private ownership is more stable than other owner types. The survival rate for buildings that undergo a change of their function is less predictable than for those without a change of function. The predictability of the states of buildings without ownership change has a greater variation than that of buildings with owner change. A clustering of building histories into groups of similar patterns can be used to calculate the probability of survival for a given building.

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
