Design delays are one of the biggest issues facing the construction industry and affecting delivery in terms of time, budget and the required quality. The characteristics of delay factors and their level of impact vary from project to project, ranging from a few days to years. They have significant financial, environmental and social impacts in construction projects; so, it is vital to investigate the causes of delay. Therefore the aim of this research is to assess and reduce design delay occurs in the planning and design phases in construction projects in Gaza Strip. Literature review about design delay was reviewed to identify the factors affecting the design delay of construction projects. In addition, other local factors have been added as recommended by local experts. A quantitative methodology was adopted to achieve research objects. The questionnaire method was selected and pilot study of the questionnaire was achieved by a scouting sample. A structured questionnaire was sent to engineers at consultants companies and owners in Gaza-strip. One hundred questionnaires were distributed on the selected sample. Based on 85 valid responses, the most effective factors that can affect design delay was determined. Analytical results revealed that all the respondents agreed to all the studied factors, and each of them have an effect on design delay, but with different ratio, and all parties( owner, consultant) have a role in design delay. It is clear also that financial factors are common effective factor on design delay for each part. Contract changes and variations affect design delay as owners hadn't a clear vision for project and its output, which may return to the unstable economic , political, and social environment in Gaza Strip. Majority of respondent agreed that all proposed minimizing design delay method can help in minimizing design delay, but with different percentages. It is recommended to develop models in order to measure design delay in construction projects in Gaza Strip, also it is recommended that the concerned bodies and parts to establish a minimum wage system and to monitor implementing this system.
