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