Because of the increasing need to improve quality in construction projects, it is necessary to reduce and prevent reworks, and that is by understanding their roots and recognizing their causes. So this research studies reworking on local projects (Syrian buildings) in terms of causes and classifications. Information was collected from questionnaire that identified some variables (100 variables) contributing to reworking. These variables were categorized according to seven main headings: human, coordination and communication, technical and engineering, owner, project management, contract, and design. Responses were further condensed using factor analysis to group the variables into basic factors. This study revealed that the sources of reworks included inexperienced personnel, projects executions after a long time of studying, a short period given by owner, poor total project management, inadequate study for project before bidding, and separation between design and executing. Finally, this research recommended that a total commitment to quality management policy applications would lead to a reduction in reworks on Syrian construction projects.

Research summary
تتناول هذه الدراسة العوامل التي تؤدي إلى إعادة العمل في مشاريع التشييد السورية. تهدف الدراسة إلى فهم أسباب إعادة العمل وتصنيفها لتقليلها ومنعها، وذلك من خلال جمع المعلومات عبر استبيان شمل 100 متغير تم تصنيفها تحت سبعة محاور رئيسية: بشرية، تنسيق وتواصل، فنية وهندسية، المالك، إدارة المشروع، العقد، والتصميم. استخدمت الدراسة التحليل العاملي لتجميع المتغيرات إلى عوامل أساسية، وكشفت عن أهم المصادر التي تؤدي لإعادة العمل مثل: العمالة غير الماهرة، تنفيذ المشاريع بعد فترة طويلة من الدراسة، المدة القصيرة التي يحددها المالك، سوء إدارة المشروع، الدراسة غير الكافية للمشروع قبل التقدم للعرض، والانفصال بين عملية التصميم والتنفيذ. أوصت الدراسة بتطبيق سياسات إدارة الجودة لتقليل إعادة العمل في مشاريع التشييد السورية.
Critical review
تعتبر هذه الدراسة مهمة لفهم العوامل التي تؤدي إلى إعادة العمل في مشاريع التشييد السورية، وقد استخدمت منهجية بحثية قوية تشمل التحليل العاملي لجمع البيانات وتحليلها. ومع ذلك، يمكن توجيه بعض النقد البناء للدراسة. أولاً، قد يكون من المفيد توسيع نطاق الدراسة لتشمل مشاريع في مناطق أخرى غير سوريا للحصول على نتائج أكثر شمولية. ثانياً، يمكن تحسين دقة النتائج من خلال زيادة حجم العينة المستخدمة في الاستبيان. ثالثاً، لم تتناول الدراسة بعمق كافٍ كيفية تطبيق سياسات إدارة الجودة بشكل عملي وفعال في السياق السوري، وهو ما يمكن أن يكون موضوعاً لدراسات مستقبلية.

Poor design is a major factor in reducing the overall performance of construction projects as well as being directly responsible for many projects cost overrun, delay and being plagued with rework, variations and disputation. This research discusse s the main factors affecting Design Quality in the Construction Industry in Syria. The result is based on a number of interviews and questionnaire surveys involving 54 designers, contractors and construction professionals. The survey identified 45 different factors classified in categories related to designer, management of the design process, owner and design documents. The severity of those factors was measured by the level of importance and was ranked according to the importance index. It was concluded that, insufficient overall design time, method of selecting the designer based on the lowest price offer, lack of documentation and changes client’s requirements were the most important factors. The results show that designers and contractors have different perceptions of the quality of design factors. The aim of this study is to assist all construction parties to plan effectively before starting a project during the design phase in order to minimize problems and eliminate extra costs needed to complete the defective design. Finally, some recommendations were made in order to improve the design quality in the construction industry.
Construction projects are characterized as very complex projects. This is because of their uniqueness, dynamic political and economic circumstances, weather, long life of projects, fluctuations in resources prices, and changes of engineering require ment, etc. Therefore, construction projects are subject to a wide range of various risks, which in case these risks occur will have considerable impacts on projects objectives in terms of time, cost and quality. Therefore, there is a need to investigate these risks and their impacts on project objectives and parties. The Client is one of the most important party in any project, and it usually lacks to have a clear strategy and policy to deal and manage risks that affect its objectives. This study aims to produce a strategy to deal and manage risks during construction stage from the client's point of view. The construction stage is selected because it takes a long time of the project life and consumes the largest amount of project budget, and it highly affects the project success or failure. Data were collected, by utilizing both questionnaire and interview survey, from more than one hundred participants from construction companies, clients and other construction professionals. An SPSS17 and EXCEL software were used to treat the data to find correlation between different variables, means and standard deviations. Risks were ranked based on risk importance indicator. The results showed that the most important risk is 'delay of payment to contractors as agreed in the contract' and the lowest risk is 'changes of design during construction'. The study concluded that the client should be concerned to formulate a specialized team in risk management in order to assist him in decision making process and developing practical solutions for dealing with risks in the construction sector.

this study a questionnaire was implemented as a primary procedure for any methodology of risk management, and send out to the experts who work in the field of construction, in order to evaluate the reality of our projects as well as determine the serious problems, and all of this aim to form checklists including the major risks which the our projects are facing to be as a guide for early risks alert, to adopt the proper responses to deal with them.
Changes in construction projects are considered as prevalent phenomenon. Where, most of projects face changes in drawings, specifications, work scope, or contractual conditions. The traditional construction followed in Syrian projects has a long t ime span between planning, design, and construction. As result the possibility of changes occurrence in any project becomes considerable. There are many causes of change orders in construction industry. These changes, mostly causes time and cost overrun and managerial complications. The objective of this study is determining the main causes of change orders; arranging them according to their significance; and studying their effects on project’s cost and time. The owner or the engineer supervising the project is the party who is responsible for change orders in the project.
Construction projects are subject to risks and uncertainties which affect project targets (cost, time, quality and safety). This paper reviews risks and their effects on construction projects in Syria, and it aims to develop risk management framew ork. In this work, risks in construction projects have been defined based on the literature review and interviews of some experts in the construction field. A questionnaire was designed to define the probability of risk occurrence and their effects, also to define the level of their effects by multiplying the probability occurrence with the effects. Another questionnaire was designed to define the extent of the effects of the most important risks on each target of the project, and to specify the procedures applied as a response to the risks. The results of this research revealed that "the Inflation, price changes" and "the difference between contracted quantities and actual quantities " are seen as the most important risk, where the studied risks in this work affect the schedule more than any other project targets. Also the results showed that avoiding the risks at the construction stage is the most used action.
