Material Handling In Urban Areas

A basic ingredient for rapid tunnel excavation is material handling. In construction of tunnel projects in urban areas material handling requires additional input to maximize performance. Urban projects share the same problems experienced in all tunnel construction and they must be dealt with. Howeve.., Urban constraints add a larger dimension. APPLICATION ENGINEERING A MUST A word of caution. To achieve increasing speed of excavation in tunnels whether in Urban areas or elsewhere will require much creative thought and energy. It would be a false premise to assume that major breakthroughs will result from this conference, or shortly thereafter, or to hope that a success here or there can translate into a universal solution. The reality, as we see it is that rapid progress and great economies will accrue on any given project only if effective application engineering is carried through. By all means take advantage of past experiences but, do not at the peril of costly undertaking, blindly accept the program of a successful job elsewhere as automatically suited to your project. Tunnel construction in urban areas is at best a difficult undertaking made more difficult in this period of greater awareness of environment, of conservation and of the quality of living by sophisticated urban communities,. A construction job represents a necessary nuisance to urban communities. To minimize this nuisance many regulatory laws are adopted. These regulations can and do slow down tunnel jobs and pyramid costs.
