| Summary: | The construction sector is responsible for providing fundamental physical structure required for living
and survival of human life. Increased development works have led in resulting the massive amount of
waste generation in developing countries. Due to poor management system on sites, it has become
more crucial and exerts several negative impacts on society and the environment. This Unused waste
material has a negative impact on the ecosystem and needs a considerable amount of money for
recycling, reusing and disposal of the waste. Like other developing countries Pakistan is spending a
significant portion of its GDP on handling construction waste. Among the several other factors, the key
contributes are highlighted in this study. This study is exploratory work investigating the types of
construction waste generated on site and their relative impact of the project cost in construction projects
of Pakistan. Through questionnaire the opinion of clients, consultant and constructor have been taken
to identify the major types of waste having more impacts on cost and time. Through Average index,
severity index and importance index, the probability of occurrence of waste through different materials,
severity level of waste production by these materials, and the overall effect of all waste generating
materials have been found respectively. Among the materials sand, concrete, tile is the most common
materials, which are responsible for a waste generation while time and cost are the two most common
non-physical waste generating factors. |
