تتميز مشاريع التشييد بخصوصيتها و كثرة العوامل المؤثرة فيها؛ مما يجعلها عرضة لعدم التأكد و للمخاطر التي قد تؤثر في أهداف المشروع (الكلفة و الزمن و الجودة و السلامة المهنية). يستعرض هذا البحث المخاطر في مشاريع التشييد في سورية، و تأثيرها في أهداف المشروع، و هدف إلى تطوير هيكلية لإدارة هذه المخاطر. حددت في هذا البحث المخاطر في مشاريع التشييد بالاعتماد على الدراسة المرجعية و على عدد من المقابلات مع خبراء في صناعة التشييد، ثم صمم استبيان لتحديد احتمال حدوث المخاطر و تأثيرها، و حدد مستوى أهميتها بدمج معياري الاحتمال و التأثير المحتمل، و صمم استبيان ثانٍ لتحديد مدى تأثير المخاطر المهمة في كل هدف من أهداف المشروع و الإجراءات المطبقة في سورية للاستجابة للمخاطر. أظهرت نتائج البحث أن مخاطر "التضخم و تقلبات الأسعار" و "الاختلاف بين الكميات الفعلية و العقدية" تعد من أهم المخاطر. و تؤثر المخاطر المدروسة في الجدولة أكثر من الأهداف الأخرى. و ظهر أن تجنب المخاطر هو الإجراء الأكثر استخداماً للاستجابة للمخاطر، يليه القبول المخطط لها و تحويلها لأطراف أخرى ضمن الشروط العقدية.
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 framework. 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.

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.

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.
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.
Economic growth and high competition have put a strong pressure on construction companies to improve their productivity and performance. Many studies on performance measurement have been carried out at the project level. Recently, the demand for perf
ormance evaluation at the company level has increased. This paper aims to identify a set of Key Performance Indicators (KPIs). A List of 20 potential performance indicators has been identified according to Balance Score Card (BSC) through a quantitative and qualitative analysis. We have obtained the required information about the relative importance of the indicators through interviews with six experts in the construction industry to determine the size of the relative importance of each indicator, on the grounds that a large number of performance indicators are difficult to measure and control. We have adopted the Analytic Hierarchy Process (AHP) to identify fewer and more effective performance indicators. And we have used Expert Choice software to analyze expert answers. As a result, we have obtained 9 important indicators which can be directly used as indicators to measure and identify performance projects or as indicators within an integrated system, for performance measurement and tracking helps in improving the performance of construction projects in Syria.
