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.
