تعتبر إدارة المخاطر في مشاريع التشييد هامة لإتمام أي مشروع بنجاح، و قد وصفت المراجع النظرية لإدارة المشاريع بشكل مفصل و دقيق عملية إدارة المخاطر الناجحة للمشاريع الهندسية، و حددت أربع مراحل أساسية لتقدير المخاطر و التعامل معها و هي تحديد المخاطر، تقييم المخاطر، التخطيط للاستجابة، التنفيذ. و مع ذلك فإن صناعة التشييد في سوريا تشهد غياباً شبه كامل لإدارة المخاطر، و من هنا أتت فكرة هذا البحث لمعرفة مدى وعي المعنيين في صناعة البناء و التشييد في سوريا حول الأنواع المختلفة للمخاطر المتعلقة بصناعة التشييد، و نفذ استبيان لآراء مجموعة من الخبراء في مجال المشاريع الهندسية (مدراء مشاريع، مهندسي تنفيذ، مصممين)، بالإضافة إلى مقاولين و مقاولين ثانويين ممن يقومون بأعمال التنفيذ في موقع المشروع و يتأثرون بخطة المشروع و يؤثرون بها بشكل مباشر.

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.
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.

The aim of this study is to develop a fuzzy inference model to
estimate the impact of change orders on the duration of
construction projects in Syria. This can help in obtaining the
optimal estimation of the increasing of the project duration caus
ed
by the changes. The capability of gradient estimation of the fuzzy
logic approach reduces the distrust of estimation using factor
assessment. Also it estimates the duration of the project after any
change.via the experts evaluation or according to the crisp logic.
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 (Sy
rian 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.
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.
