The first residential building of slipform construction; erected in 1950 in Västertorp, Sweden, by AB Bygging Later picture of the residential building in Västertorp. Slip forming, continuous poured, continuously formed, or slipform construction is a construction method in which concrete is placed into a form that may be in continuous motion horizontally, or incrementally raised vertically.
Short forms, up to 60 cm high, are placed on both sides of the wall to serve as a guide for the stone work. The stones are placed inside the forms with the good faces against the form work. Concrete is poured in behind the rocks. Rebar is added for strength, to make a wall that is approximately half reinforced concrete and half stonework. The ...
With multiple forms, the entire floor of a building can be done in a single pour. Tunnel forms require sufficient space exterior to the building for the entire form to be slipped out and hoisted up to the next level. A section of the walls is left uncasted to remove the forms. Typically castings are done with a frequency of 4 days.
Jump forming, also known as climbing forming, is a method of construction whereby the walls are cast in discrete lifts. It is a stop-start process with day joints formed at each lift level. Similar to slip forming, jump forming is only efficient for structures with repetition of wall arrangement.
Slip forming, a widely used technique today for building vertical concrete cores for high-rise buildings, was developed in the early 20th century for building silos and grain elevators. The concept was pioneered by James MacDonald, of MacDonald Engineering Chicago, and published by Milko S. Ketchum in an illustrated book: The Design of Walls ...
In modern rammed earth buildings, the walls are constructed on top of conventional footings or a reinforced concrete slab base. Contemporary slip formwork in use. The construction of an entire wall begins with a temporary frame, the "formwork", which is usually made of wood or plywood, as a mold for each wall section's desired shape and dimensions.

Construction involves the creation of physical structures such as buildings, bridges or railways. Bricks are small rectangular blocks that can be used to form parts of buildings, typically walls. Before 7,000 BC, bricks were formed from hand-molded mud and dried by the sun.
