Device, a system and a method for building stationary structures on a working surface

A system comprising:

• a device for building stationary structures on a work surface, the device comprising a scaffold, which is arranged around the work surface;
• an external computing unit;
• and
• a crane that is communicatively coupled to the external computing unit,
• wherein a working head is held on the scaffold and is arranged above the work surface via multiple control cables, the multiple control cables including upper control cables and lower control cables,
• wherein the upper control cables run above the working head from the scaffold,
• wherein the lower control cables run below the working head from the scaffold,
• wherein the upper control cables and the lower control cables are extendable out of the scaffold and retractable to the scaffold in order to change a position of the working head,
• wherein a control unit of the device is connected with actuators for the extending and retracting of the upper control cables and the lower control cables, the control unit being configured with control data received from the external computing unit to actuate the actuators to change the position of the working head, the working head holding a nozzle, wherein the nozzle is communicated with a concrete source via a line,
• wherein the actuators are positioned above the working head and below the working head,
• wherein the control data is modified based on a comparison of data received from a sensor monitoring construction progress to a Building Information Modelling (BIM) database, and
• wherein the control data of the control unit is further used to control the crane, the crane being separate from the working head and the scaffold.

A method for automated or semi-automated building of stationary structures on a work surface using a device, or a system, the method comprising:

• spraying a sprayable building material via a line onto the work surface, or onto existing structures on the work surface out of a nozzle held or arranged on a working head;
• and
• moving a magazine with prefabricated components via the working head,
• wherein a movement of the working head is caused through a retracting or extending of control cables that are actuated by a control unit via control data,
• wherein the control data is modified based on a comparison of data received from a sensor monitoring construction progress to a Building Information Modelling (BIM) database, and
• wherein the sprayable building material that is sprayed is atomized shotcrete.
