Evaluating Environmental Impacts of Open-cut vs. Trenchless in Egypt

During the rapid growth of infrastructure projects globally, countries pay high environmental and social costs as a result of the impacts caused from utilizing the traditional open-cut utility installation method that still widely being used in Egypt. For that, it was essential to have alternatives to reduce these environmental impacts and social costs; however, there are some obstacles that prevent the implementation and the realization of these alternatives.This research is conducted mainly to evaluate the environmental impacts of open-cut excavation vs. trenchless technology in Egypt, through two main methodologies. Firstly, a field survey that aims to measure knowledge of people working in the Egyptian construction industry of trenchless technology, and the harms caused from keeping utilizing open-cut for installing all kinds of underground utilities. In addition to investigating the reasons behind not relying on trenchless technology as a safe alternative for open-cut in Egypt. Furthermore, in order to compare the greenhouse gases emissions resulted from both open-cut vs trenchless technology, a real case study is applied quantifying the amounts of the resulted greenhouse gases from each method. The results show that greenhouse gases emissions generated from open-cut were extremely higher than that of horizontal directional drilling as a trenchless installation method.
