Depending on the project, the bored pile retaining wall may include a series of earth anchors, reinforcing beams, soil improvement operations and shotcrete reinforcement layer.
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.
Timber-pile bridge with steel stringers, New Jersey. Timber pilings serve as the foundations of many historic structures such as canneries, wharves, and shore buildings.

Franki piles can be installed raked (or sloped) with a tilt of up to 4:1. [5] Raked Franki piles are always reinforced and are particularly suitable for structures subject to dynamic forces. [1] Driving methods such as open-ended coring, rock socketing, and composite shaft construction are occasionally used to overcome unique site problems. [3]
Educational software, as the name implies, are a subset of educational games which attempt to teach the user using the game as a vehicle.
