| Summary: | Huge amount of construction wastes generate annually and affecting our environment. To reduce this impact,
construction practitioners need to determine significant contributory factors of waste generation before engaging with
construction works. Hence, this study determines significant factors and groups of factors affecting on construction
waste generation. Vigorous literature review identified 81 factors for causing construction waste and clustered in 7
groups of factors namely Design, Handling of Materials and Equipment, Workers, Management, Site Condition and
Procurement and External. A structures questionnaire designed based on these factors was surveyed and interviewed
among 30 experts in construction industry. Respondents need to ranks the factors and also to conform whether the
factors belong to the assigned group. Analysis indicated that all the respondents agreed with the factors assigned with
the group and mean rank analysis found that 77 factors are above significant level to Malaysian construction
environment. These 7 groups of factors were developed into PLS-SEM model to determine significant level in
contributing to construction waste. Outcome from the model identified that Procurement group has highest impact on
construction waste generation with path coefficient value of 1.188. This model will be useful to entire construction
players and help the country to minimize construction waste generation. |
