In order to evaluate the quantity of construction waste generated,
the following assumptions were made: (a) new residential
building activity generated 21.38 kg/m2 of waste, and (b) new
non-residential building generated 18.99 kg/m2 (HQ Air Force Center
for Environmental Excellence, 2006). The amount of construction
waste was determined according to the method outlined by
the HQ Air Force Center for Environmental Excellence (2006). Only
waste generated as a result of construction activity from 2002–
2005 was estimated in this study. The construction and maintenance
of infrastructure (such as bridges and highways) were not
considered due to the lack of data on these activity types. Demolition
in any form was also not considered for the same reason.
