Construction industry is considered as one of the most important industries inPalestine. It is well known that most construction projects in Gaza Strip exposed to time and cost overrun or both. This phenomena may affect the progress of construction industry in Gaza Strip as well as may expose many institutions of construction to be destroyed. Literatures of previous studies were classified into two main parts which are: (1) factors influencing time overruns of project; (2) factors influencing cost overrun. Most related researches were revised which included the study of these factors in many countries. The aim of this research is to assess factors influencing time and cost overruns on construction projects in Gaza Strip. The objectives of the study were achieved through two approaches, the first one was a valid questionnaire that was obtained from contracting companies, consultants, and owners in Gaza Strip. The second by studying five cases with five projects exposed to time and cost overrun. The study clarified that “Strikes, Israeli attacks and border closures" was the most critical factor that influence project delay. The survey also indicated that "material- related factors" occupied the second rank in importance, where "the lack of materials in markets" and "delay in materials delivery to the site" were among the most important factors affecting delay. The study illustrated that "prices fluctuations of constructions materials" which was due to border closure was one of the most important factors that may lead to cost overrun. Also it clarified that contractor's delay of material delivery and equipment have led to cost overrun. The study also clarified that prices inflation highly contributes to cost overrun. The study recommended owners, contractors, and consultants to hold their responsibilities to avoid any delay or cost overrun which could be achieved by good management of the project and finding new methods for storing the needed materials from the beginning of the project. The study also recommended the government to adopt laws through Palestinian legislative council to prevent materials monopoly. Also it recommended the government with the necessity of dealing with new entrances such as Rafah entrance to guarantee material transfer into Gaza Strip.
