Abstract:
As a result of rapid population growth and the lack of adequate controls unplanned construction has increased rapidly in Istanbul up to 1995. Since 1995, in order to prevent irregular urbanization rate, controls have been increased using technology and public housing constructions have been accelerated. Satellite cities with all kinds of planned infrastructure have been created in buildable areas of the city. Despite the acceleration of the establishment of satellite towns in recent years, unplanned construction from the past is existed in a large part of the province. Sustainable development is possible only with the minimization of the high infrastructure costs, urban planning and by having different institutions with infrastructure services that generate joint plans. However, it is a bit late for this goal since a large part of Istanbul completed the process of urbanization. First of all, the solution to the problems of the existing infrastructure should be realized from a headquarters. So, coordination between institutions those provide water and sewerage, electricity, telephone and gas infrastructure services and transportation services of municipalities from a headquarters. Transport infrastructure of the relevant municipalities should also be considered since infrastructures are usually built underneath the pavement and the roads. Concrete channel with a cover known as the Utility Tunnel is proposed for Istanbul as an innovative solution for infrastructure problems. This system provides the implementation of the water, electricity, gas and telephone as well as a combination of infrastructure systems in a single place where the repair and the renewal will be much easier. The ultimate goal of the proposed study is to create a center for the coordination of problems before they occur, and to create many scenarios about infrastructure problems, also to provide necessary prompt and long term innovative and economical solutions based on the infrastructure of the Istanbul.
