Suspended translating platform

A method of forming a wall section using a formwork assembly and an external platform system, comprising:

• suspending a platform from one or more overhead support structures, the one or more overhead supports comprising at least one of a gallows beam or a support beam;
• attaching a working bracket to an existing wall section;
• attaching the working bracket to the overhead support structure such that the working bracket supports the overhead support structure;
• positioning a plurality of formwork elements of the formwork assembly to define an intermediate space for receiving fresh concrete;
• positioning a connection reinforcement element in the intermediate space defined by the formwork assembly such that the connection reinforcement element projects outwardly with respect to at least one of the plurality of formwork elements;
• pouring fresh concrete into the intermediate space defined by the plurality of formwork elements of the formwork assembly;
• actuating a linear actuator by a user positioned on a working surface of the platform or at a position remote from the platform;
• in response to the actuating of the linear actuator, translating the platform away from the plurality of formwork elements from a working position to a climbing position such that the working surface of the platform maintains a constant area, the working surface remains level throughout the translation, and the connection reinforcement element is clear of a vertical climbing path of the platform;
• and
• climbing the external platform system.
