Project Update 9-1-2010
Through October, the contractor is excavating for the proposed pump station and valve vault. This phase of the project entails excavating, moving, and transferring material on and offsite. The contractor is operating heavy excavating equipment and loading and unloading dump trucks. As the excavation increases in depth, the contractor will install a temporary shoring system in order to keep the excavation pit from collapsing. Shoring is a general term used in construction to describe the process of supporting a structure in order to prevent collapse so construction can proceed. For this project, the process involves excavating five feet in depth, installing shoring nails, applying a steel mesh and covering with concrete.
