Abstract
Waste has been recognized as a major problem in the construction industry in developed
and developing countries. It has a considerable impact on the efficiency of the construction industry
and the overall economy of the country. Waste in construction is not only focused on the quantity
of material waste in construction, but also related to time waste. The aim of this paper is to identify
causes of time waste in construction projects and to rank these factors according to their importance
from contractors’ viewpoint in the Gaza Strip. The research approach adopted in this study was
questionnaire survey. 80 valid questionnaires have been studied and analyzed. The results of
analyzing 92 causes of time waste considered in this survey indicated that: rework that don’t comply
with drawings and specifications; lack of materials availability; rework due to workers’ mistakes;
effects of political and social conditions; and owner’s poor communication with the construction
parties and government authorities are the most five significant sources of time waste during the
construction process. The survey revealed that the site supervisor group is the major cause of time
delay. It would be appropriate to arrange formal and informal education and training in time waste
management for all concerned parties in the construction industry.
