Abstract: A building system for fabricating a multi-storey building structure, the system comprising at least one first building structure and at least one second building structure and a way for elevating the second building structure to allow provision of the first building structure under the elevated building structure. A method for fabricating a multi-storey building structure, the method comprises the steps of providing a second building structure; elevating the second building structure; providing a first building structure under the elevated second building structure; and lowering the second building structure onto the first building structure. There is also provided the elevating means, such as jacks for elevating the building structure.

Abstract: A control system for controlling the operation of a plurality of modular lifting units (12). The control system includes a power source (20) for providing power to each of the modular lifting units (12). A main control box connected between the power source (20) and the modular lifting units (12), comprises a mode switch (28) for switching the system between two control modes: a group mode, in which the plurality of modular lifting units (12) is controlled synchronously as a group; and, an individual mode, in which any one of the modular lifting units (12) is controlled independently of the other units. In group mode, synchronous movement of the modular lifting units is achieved by setting each unit to run at the same speed.
