Abstract
Deconstruction—the systematic disassembly of reusable and recyclable components and materials—is being actively promoted in a growing number of US cities to reduce the enormous amount of construction demolition waste sent to landfill. Research has highlighted local and regionally specific criteria influencing the decision on deconstruction, but it remains unclear how to decide which city-owned condemned properties in Pittsburgh should be considered for the new deconstruction pilot program. Therefore, this study establishes a prioritization model to distinguish the relative importance of factors using the analytic hierarchy process (AHP). According to local experts, the four most impactful criteria are the environmental impact, economic impact, resources and type of properties. Fourteen factors within these criteria are selected for detailed comparison. The relative importance of these factors is then used to weight spatial map overlays to classify condemned properties into four deconstruction value categories. As a result, this study offers a new methodology to evaluate potential deconstruction projects by weighting the criteria most valued by decision-makers in Pittsburgh, which could be altered and expanded to fit the values of other cities.

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
