Developing framework to optimize the preparation of (EOT) claims using integration of (LPS) and (BIM) techniques in construction projects

Construction projects face delays and disturbances that could be caused by one of the contracting parties, both of them, or beyond their control. proving the delay needs a significant effort to introduce all details, documents, and records which explain the causes of the delays. the contractor needs to submit a claim, whether it is extension of time (EOT) claim or any claim with an adequate definition, causation, liabilities, analysis of delays to get an extension of time-related to the risk event. claims preparation processes need to be collected and documented daily throughout the project phases, especially during construction phases. lean construction, with its common technique, the last planner system (LPS), and building information modeling (BIM) have significant synergies and can bring benefits when implemented together to support the preparation of the extension of time (EOT) claim. building information modeling used as a digital platform to facilitate communication between the project team, improve project performance, and implement the last planner system (LPS) phases effectively. (LPS) is enhancing the coordination within the project team. the primary purpose of the research is to develop framework to optimize the preparation of extension of time (EOT) claims using integration of the last planner system (LPS) and building information modeling (BIM) techniques in construction projects. the integration will represent in implementation of the appropriate (BIM) functionalities along with the five phases of the last planner system (LPS). as a result of the integration, the inputs and outputs well documented, which considered as the primary support to the processes preparation of the extension of time (EOT) claim. also, the framework supported by process flowchart to clarify outputs, inputs, and the project team's responsibility, which will contribute to optimizing the preparation of the extension of time (EOT) claims. المشروعات الإنشائية تواجه تأخيرات واضطرابات والتي من الممكن أن يكون سبب فيها أحد طرفي التعاقد، كلاهما، أو خارجه عن إرادتهما. يحتاج إثبات التأخير إلى جهد كبير لتقديم جميع التفاصيل والوثائق والسجلات التي تشرح أسباب التأخير يحتاج المقاول إلى تقديم مطالبة، سواء كانت مطالبة تمديد زمني (EOT) أو أي مطالبة مع تعريف مناسب، الأسباب، المسئوليات، تحليل التأخيرات للحصول على تمديد الوقت المرتبط بالحدث. تحتاج عمليات إعداد المطالبات إلى جمعها وتوثيقها يوميا على مدار مراحل المشروع، وخاصة خلال مراحل الإنشاء. نظام Lean Construction بتقنيته الشائعة (LPS)، و
