Before the second lift can begin, the necessary anchors must be in place and the first lift must be of sufficient strength. Tower cranes are used to assemble and place the form system on the starter wall.
Form and Ram Placement
The inner form and raising rams are attached to the anchors when the first lift has gained sufficient strength. Once the inner form is in place, the outside form is rolled back on the trolley system, permitting the cleaning and oiling of forms, installation of form liners, steel reinforcement, embedments, and box-outs. The outside forms are then rolled into position, allowing the installation of taper ties.
