تستهدف هذه الدراسة تحديد العوامل التي تسهم في تأخير المشروعات الإنشائية نتيجة الأوامر التغييرية. ويتم تحليل تأثير التغييرات على الموارد المتاحة، مثل العمالة والمواد والمعدات، وتقييم التأثير على الجدولة الزمنية للمشروع، كما يتم تقدير التكاليف الإضافية المرتبطة بتلك التغييرات، وتستند هذه الدراسة إلى استخدام أفضل الممارسات لتقليل تأثير الأوامر التغييرية على تأخير المشروعات. يشمل ذلك إعداد آليات فعالة للتحكم في التغييرات وتقديمها بشكل منظم ومحكم، بالإضافة إلى وضع إجراءات لتقييم تأثير التغييرات قبل الموافقة عليها وتنفيذها. وباختصار، تهدف الدراسة التحليلية للأوامر التغييرية وأثرها على تأخير المشروعات الإنشائية إلى فهم وتحليل تأثير التغييرات على جدولة وتنفيذ المشروعات، وتقديم توصيات لتطوير ممارسات فعالة لتقليل هذا التأثير وتحقيق تنفيذ ناجح للمشاريع الإنشائية.

Change management in construction and engineering projects refers to the process of dealing with odifications and alterations that occur during project execution. These changes can be related to scope, specifications, schedule, or costs. When change management is not effectively handled, it can negatively impact project implementation and cause delays. There are several effects that may result from poor change management in projects: Schedule delays: When changes occur in the scope, specifications, or schedule, they can lead to project delays due to the need for replanning, resource reallocation, and adjustments to the original timeline.
Cost increases: Changes often result in additional costs, whether due to the extra expenses of implementing the change or its impact on resource utilization or schedule, leading to increased labor and equipment costs.
Impact on project quality: If changes are not properly addressed according to the required standards and specifications, it can have a negative effect on project quality and the performance of the final product.
Execution slowdown: When a change occurs in the project, it can cause a disruption in execution and shift the focus towards addressing the change instead of continuing regular work on the project. This recurring interruption in execution can result in a general delay in project completion. To mitigate the negative effects of changes on project delays, effective change management procedures should be in place. All changes need to be documented, and their potential impact on schedule, costs, and project quality should be evaluated. There should also be a mechanism for decision-making regarding the approval and effective implementation of changes. This requires good communication among all stakeholders and their collaboration to manage changes effectively, prioritize them, and make appropriate decisions. Additionally, there should be a balance between the necessity of managing changes and maintaining project stability. This means that changes should be carefully assessed and their potential impact analyzed before making decisions regarding their approval. Furthermore, ensuring the availability of necessary resources to properly implement changes without negatively affecting the overall project timeline is crucial. In summary, change management in construction projects plays a crucial role in avoiding project delays. It should be carried out effectively and systematically to ensure project implementation is on time and meets the required specifications. Changes should be transparently and organizedly addressed, and there should be good communication and collaboration among all stakeholders to achieve the best results for the project.
