Classification of Construction Waste Generation Attributes in Project Life Cycle

Abstract

Waste generation is a major issue faced by construction projects. Construction waste has adverse effects the time, cost, productivity and economy of the industry. There are different causes of waste generation in different countries of the world. An extensive literature was carried out to identify the common factors of construction waste generation which resulted in identifying 59 common attributes. Through structured interview data was collected to classify the attributes on different stages of construction project lifecycle. A total of 15 experienced practitioners were interviewed classify the attributes into different stages of project life i.e. planning, design, construction and finishing. Frequency analysis of the perception of the practitioners showed that there are 25 attributes in planning stage, 9 in design stage, 53 in construction stage and 5 in finishing stage. From the findings it can be seen that construction stage is the critical stage in which 53 attributes are occurring. This study shows that the practitioners need to be very careful during construction phase for controlling construction waste generation.
