According to the invention, a system for slip forming a building core is disclosed. The system may include a form and a plurality of extendable mechanisms. The form may include an inner and outer frame. The outer frame and the inner frame may define a space between the inner frame and the outer frame. The form may also be configured to accept a hardenable substance in the space, where the hardenable substance may form the building core. Each of the plurality of extendable mechanisms may include a first end, a second end, and an extendable midsection. The first end may be coupled with the form. The second end may be configured to be supported with a wall of the building core. The extendable midsection may be configured to change the distance between the first end and the second end so the form may be moved to a different elevation.
