Many studies have tried to determine the impact of change orders on the cost and time of the project, which in turn leads to differences and disputes between contractors and owners. Where change orders dealt with in various engineering projects. This search displays formal causes of change orders occurring during the life cycle of the project in Syrian coastal zone. Particular building projects are studied, and the most important impact on completion of the project indicators (cost_time) is discussed. Also identifies the party responsible for the change, and shows the weak points during follow the change order life cycle and provides recommendations for each of the responsible parties, stressing the need to monitor performance in order to manage change order and address the causes and impact alleviation. The prediction models were drafted at additional cost that may result from change orders.

Research summary
تناولت هذه الدراسة أسباب أوامر التغيير النظامية وتأثيرها على مشاريع الأبنية في المنطقة الساحلية في سوريا. يهدف البحث إلى تحديد أسباب أوامر التغيير التي تحدث أثناء دورة حياة المشروع الإنشائي، وتحديد الطرف المسؤول عنها (إدارة أو دارس)، وتحليل تأثيرها على تكلفة وزمن المشروع. تم استخدام المنهج الإحصائي التحليلي من خلال مسح عينة من مشاريع الأبنية في المنطقة الساحلية، وتم تسجيل البيانات المطلوبة وإدخالها في برنامج SPSS. أظهرت النتائج أن الإدارة (المالك والمشرف) هي أكبر مسبب لأوامر التغيير بنسبة 60%، تليها الجهة الدارسة بنسبة 40%. كما تبين أن أوامر التغيير تؤدي إلى زيادة في تكلفة المشروع بنسبة 31% وزيادة في مدة الإنجاز بنسبة 29%. تم اقتراح نماذج للتنبؤ بالكلفة المضافة نتيجة أوامر التغيير باستخدام برنامج SPSS، وتم تصميم واجهة حاسوبية لتسهيل استخدام هذه النماذج من قبل أطراف المشروع. أوصى البحث بتفويض الإدارات الفرعية ببعض صلاحيات الإدارة العامة، وتحفيز الدارس من خلال مكافآت، واتباع سياسة التأهيل المسبق للدارسين.
Critical review
دراسة نقدية: تعد هذه الدراسة مهمة في مجال إدارة المشاريع الهندسية، حيث تقدم تحليلاً شاملاً لأسباب وتأثيرات أوامر التغيير النظامية على مشاريع الأبنية. ومع ذلك، يمكن توجيه بعض الانتقادات البناءة لهذه الدراسة. أولاً، قد يكون من المفيد توسيع نطاق الدراسة ليشمل مناطق أخرى في سوريا أو دول أخرى للحصول على نتائج أكثر شمولية. ثانياً، يمكن تحسين دقة التنبؤات من خلال استخدام تقنيات تحليل بيانات أكثر تطوراً مثل التعلم الآلي. ثالثاً، يمكن تعزيز التوصيات بتقديم أمثلة عملية أو دراسات حالة توضح كيفية تطبيق هذه التوصيات في الواقع العملي. وأخيراً، يمكن أن تكون الدراسة أكثر شمولية إذا تم تضمين تأثيرات أخرى لأوامر التغيير مثل تأثيرها على جودة المشروع أو رضا العملاء.

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.
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.
The concept of sustainability in architecture from the perspective of architectural thought focuses on creating a successful relationship between the building and the user and the environment through sustainable design principles and the preserva tion of these principles, whether physical Ooualemanoa to maintain and build on it, the advanced materials research a high priority, where he will witness the construction further sector of evolution, and issues related to smart and sustainable buildings become more important. That was supported us to analys high-tech building materials to know their impact on the sustainability of buildings
The Dams are large and complex projects, and are generally characterized by the enormous cost of implementation in some cases, and the length of the implementation period, are rarely carried out a dam in Syria within the estimated plan which develo ped his of the cost and time, this is due to the risks that intercepted projects during the implementation phase and directly influenced the basic project objectives ( cost and time and quality). This research experiences to the reality of the implementation of the late dams, through undertake a study the risks suffered by the implementation of sector and influenced the basic objectives of the project (cost - time - quality), through a field survey study includes more than thirty-five dams in Syria. For this purpose have been used survey was distributed to a slice of experts and technicians in the form of dams, has enabled to obtain a list of the risks faced by the implementation of dams in addition to the assessment, In an attempt to develop a scientific methodology to analyze and manage the risks of dam projects by assessing the probability of their occurrence and their impact on the objectives of the project in the event of occurrence, with introduce a new standard for evaluating a detection / control, As per the approach to FMEA /Failure Mode and Effect Analysis/ and incorporate logic fuzzy, and arrange those risks according the Risk Criticality Number (RCN) for each risk early in order be sensitive to them than we can handled properly with proposing appropriate response strategies.
Due to the large increase in the use of data communication and information exchange services of different types in different environments, the standard and the programming had to be a language of characterization is ideal for scalability and develo pment that serve the growing needs in the best form and in the shortest possible time and was the most widely used language and the most widely used XML language. he adoption of graphics architecture sometimes created a problem affecting the performance of information transmission networks due to the large volume of data exchanged as well as the need for large storage capacity at both ends of the transmission and reception. Effective ways of reducing the amount of data exchanged through the network had to be found. There have been many scientific researches and practical experiments on finding effective ways to reduce the actual size of the data and by adopting different parameters that affect the process of compressing the files so as to achieve better results by reducing the volumes of files exchanged with attention to times of compression and decompression of files. In this research, we focused on the study and comparison of some compression algorithms for files and their effect on data communication in networks.
