Abstract

Egypt's construction sector faces enormous challenges related to the construction phase, the most important of which is a considerable waste of effort, time, and money that may result in increasing the risk of losing projects. Indeed, eliminating such a waste will certainly improve the project performance, thereby enhancing the value of the project stakeholders. The researcher assumes that adopting lean construction (LC) approach is necessary to reduce waste, improve performance, and enhance the performance of the Egyptian construction sector at large. The research relies on a simplified methodology that has several positive outcomes: (1) saving time and cost; (2) boosting quality and safety; and (3) improving management process control, resource management, and relationships between project team members. Therefore, the main objective of the current paper is to examine and analyse the ability of wasteless construction principles to reduce waste in the construction process through an applied case study of a large construction project in Egypt. The study employs lean construction (LC) methodology and utilizes its technologies and tools to reduce waste in construction, particularly at the finishing stage, measuring their effectiveness in achieving the desired goals. The study assumes to have two major contributions: (i) determining the main causes of waste in the Egyptian construction industry; and (ii) applying LC methodology to prevent and eliminate the causes of waste inherent in the construction process.

يواجه قطاع البناء في مصر العديد من التحديات المتعلقة بمرحلة التشييد، واهمها إهدار الجهد والوقت والمال (بذل مجهود او إنفاق بدون إضافة قيمة حقيقية للمشروع) مما يؤدي إلي زيادة في زمن وتكلفة المشروع دون إضافة قيمة. وبالتالي فالتخلص من الهدر سيؤدي إلي تحسين أداء المشروع، وتعزيز القيمة لإصحاب المصلحة من المشروع. ومن ثم يفترض الباحث أن اعتماد نهج البناء الخالي من الهدر lean construction (LC) أمر ضروري لتقليل الهدرwaste في مشروعات البناء وتحسين اداء قطاع البناء المصري ككل. وذلك من خلال الاعتماد على منهجية مبسطة تؤثر على الوقت والتكلفة والجودة والسلامة وتحسين التحكم في العملية الادارية، وإدارة الموارد، والانشطة والعلاقات بين فريق المشروع بشكل إيجابي. ومما سبق فالهدف الرئيسي للبحث هو فحص وتحليل قدرة مبادئ البناء الخالي من الهدر على تقليل الهدر في عملية البناء من خلال دراسة حالة تطبيقية لمشروع بناء كبير في مصر وتطبيق منهجية lean construction (LC) عليه لاستفادة من إمكانياتها للحد من الهدر في البناء وبخاصة في مرحلة التشطيبات. وتعتبر هذه الدراسة مفيدة من ناحيتين. اولاً: تحديدًا الاسباب الرئيسية للهدر في صناعة البناء المصرية. ثانيًا: تطبيق منهجية (LC) لمنع وإزالة أسباب الهدر المتأصلة في عملية البناء بمساعدة تقنيات وادوات(LC) وتحليل وقياس فعاليتها في تحقيق الاهداف المرجوة. وخلصت الدراسة انه بمساعدة منهجية (LC) هناك المزيد من الفرص للتخلص من الهدر بجميع أشكالها الذي لا تضيف قيمة لمشروع البناء.
