English Abstract
The main objective of this thesis is to determine the factors that cause change order in construction projects in Iraq, through conducting a case on a number of projects of the Endowment.
In order to achieve the objectives of this study, the factors causing change orders in construction projects in a number of countries were determined along with their effects on cost and duration of construction projects, through conducting a comprehensive review of previous studies conducted on the subject of the thesis.
The mythology of the study consisted of preparing a special questionnaire to explore the factors causing change orders and their impacts on construction projects.
The questionnaire was distributed to a sample of (151) consulting engineers and contractors working in the Endowment projects to answer the questions contained in the questionnaire.
The answers of the respondents were analyzed using SPSS.
At the same time, a random sample of construction projects was chosen to be the subject of a case study.
The project sample consisted of (30) projects, (20) of which were new construction projects and (10) were maintenance and rehabilitation projects.
The projects were implemented in the time period from 2010 to 2014.
After collecting and analyzing data, a comparison was made between the questionnaire results and those of the case study.
The study ended with a group of conclusions, the most important of which are: The most important factors causing change orders in construction project of Endowment in Iraq are (change in design) and (Errors and omissions in design or table of quantities) and the study confirmed that the factor (Differing site conditions) was the leading factor causing change orders in maintenance and rehabilitation projects..
Furthermore, the researcher presented a number of recommendations, the most important of which are: Serious and actual interest in designs and preparing and auditing them carefully along with terms, specifications and tables of quantities so that there is no or minimum contradiction between the contract documents and only minor changes are made and conducting accurate and detailed site investigation for maintenance and rehabilitation projects before preparing their tables of quantities.
