Summary
A lot of construction projects in the world and Iraq in particular are suffering from delay in implementation. One of the recurring problems in the construction industry is the issue of delay, which negatively affects the success of the project in terms of time, cost and quality [1]. School projects ranked first with a response rate of 27%, followed by public buildings projects with 24% response and road projects with 21% response Note that this is due to the large number of projects implemented from these types compared to the projects of electricity and transport, for example, which received the lowest rates [5]. In Iraq, according to a survey finding that many projects suffer from a great deal of delay and due to specific factors, many projects were temporarily or permanently abandoned during the political crisis between 2003 and 2014.This factor escalates disputes to be settled by litigation process. The parties involved in the project use litigation as a last resort to settle disputes [6]
