Shoring is a term used in the process of air freight container and pallet (ULD) buildup, e.g. making sure that the cargo placed in containers and on pallets is packed securely and efficiently. Specifically, shoring is done to affix cargo to the ULD and adapt different form factors of cargo items to maximize the use of the available ULD volume.
Heavy construction equipment is usually used due to the amounts of material to be moved — up to millions of cubic metres. Earthwork construction was revolutionized by the development of the scraper and other earth-moving machines such as the loader, the dump truck, the grader, the bulldozer, the backhoe, and the dragline excavator.
Tunnel Construction. Tunnels are dug in types of materials varying from soft clay to hard rock. The method of tunnel construction depends on such factors as the ground conditions, the ground water conditions, the length and diameter of the tunnel drive, the depth of the tunnel, the logistics of supporting the tunnel excavation, the final use and shape of the tunnel and appropriate risk management.

The new Austrian tunneling method (NATM), also known as the sequential excavation method (SEM) or sprayed concrete lining method [1] (SCL), is a method of modern tunnel design and construction employing sophisticated monitoring to optimize various wall reinforcement techniques based on the type of rock encountered as tunneling progresses.
Continuous flight augering can be used to construct a secant piled wall which can be used as a retaining wall or as shoring during excavation. Once initial piles are set with concrete, other shafts are augured between them, slicing into the original piles, with the new ones receiving rebar.
This method proved to be more cost-effective, while at the same time cut down the construction time when compared to other conventional support methods. [4]: 23 Germany was the next country to investigate soil nailing. From 1975 to 1981 the University of Karlsruhe and the construction company Bauer collaborated to establish a research program ...
Performance testing is a more reliable method of predicting the load-elongation behavior, and is conducted on a selected number of tiebacks in a project. For performance testing, a particular sequence of increasing and decreasing loads are applied, using equipment similar to those used in the proof test.
