The implementation of major projects is complicated by the multiplicity of beneficiaries, owners, and all participants in the project as well as the technical overlap between the various engineering, financial and administrative works, while the specific features of the construction activity have a clear influence in shaping the nature of construction projects because the implementation processes were associated with a deep and long-term intervention in the natural environment, where construction is a burden on the environment, both in the construction phase and during the maintenance and liquidation phases: it requires depreciation of a large number of material resources. Through that, this study focused on clarifying the most important concepts of risk management and modern strategies in risk analysis and how to respond to them and monitor projects. The study then presented a questionnaire for the risks facing major projects in Egypt. Through analyzing the results of the questionnaire, a qualitative risk analysis was conducted that can be used to prioritize response to risks, in addition to conducting a Monte Carlo simulation based on theoretical foundations and providing a new process for prioritizing project risks related to sustainability, where the (Primavera Risk Analysis) program was used to clarify the impact of risks on project time and cost. All analyses are based on the theoretical background regarding risk, risk management process, and project life cycle approach in the sustainable construction sector. with the help of this study, it is possible to address ways of mitigating the harmful effects on the environment through the implementation of sustainable management in the planning of future projects and better management of current projects.

The companies of the cities of the world are expanding and the number of their population increases annually, the street network remains. Reconsider reconsidering the thinking and visual of urban design and inspect the elements of urban design to serve the dimensions of urban design and its elements and its impact on human needs Therefore, the research is concerned with an analytical study of the development work for one of the main streets' models in the old cities (Al-Jaish Street in Tanta). This study is presented in three axes -The first axis: an analytical study of the relationship between the physical environmental elements and the dimensions of urban design to determine the most important problems that hinder the achievement of design dimensions Urban, Second Axis: A survey of users' opinion to achieve human needs after the development of El-Jaish Street -Third Axis: Presenting proposals for solutions to problems that impede achieving the dimensions of urban design based on the achievement of human needs that have been reached from the results of the users' questionnaire.
