Shoring is a positive ground support mechanism that can be utilized when battering and/or benching are impractical due to the location or depth of an excavation. Shoring is the providing of support for excavated face(s) to avoid soil movement and, hence, ground collapse. The aim is to provide a stable base upon which to build up the affected area. Battering is the act of driving wooden stakes into the ground to provide temporary support for a structure during construction or repair. The term comes from the need for workers to protect themselves by hitting any exposed wood with a heavy hammer to reduce the risk of it collapsing under its own weight. Benchmarking is the process of making measurements to establish the quality and quantity of materials used in the construction of something such as a building or bridge. These measurements may include dimensions, weights, capacities, or performance standards. The information obtained from benchmarking is used to ensure the continued effectiveness of the structure. Bearing walls consist of parallel rows of stones set in the ground with the gaps between them filled with rubble or earth. The wall provides stability for buildings erected on its sides. It can also protect against flooding if it stands high enough. Bearings have been used for many years in areas where stone is available to build a wall. They are also used for smaller projects such as fences and garden features.
