| Summary: | This research consists of an investigation on the incidence of residential construction
waste in Texas. Construction waste has proved to have a negative effect on the economic
health of construction companies and on the environment. To evaluate the current
methods two waste diagnostic questionnaires were developed to identify the most
frequent waste categories present in the job site affecting the final cost of the residential
projects, the types of waste and their possible causes. The questionnaires were sent to one
hundred and twenty construction companies. Three criteria were used to select companies
for the study. First, only private companies were chosen. Second, only companies doing
predominantly residential construction works were chosen. Third, only companies who
are operating in Texas were chosen. The results showed that wood, drywall and concrete
are the most frequent waste categories affecting the final cost in residential projects and
waste of materials, over allocation of materials, rework, clarifications, unnecessary
handling of materials, inefficient movement of workers, waste of space on site, and delays
are the most dominant types of waste occurring in these categories. |
