The wall was poured out. The leaning gang form remained tied and braced in place until the wall could be attached to roof-level steel beams. The wall ties are visible and also, the strongbacks to which the braces are attached, project above the wall forms.
The wall forms were first set up. To the right is the elevator core form (plywood skin faces viewer). In the foreground, the first wing wall gang form is plumbed and braced. Note the clamp connections along the vertical panel joints, demonstrating the ease of assembly for the HD 1500 Wall Forming System.
The forms were jumped for the second lift. The elevator core form is to the right behind the reinforcement. The wing wall gang is set for the second lift. Note the addition of trailing walers for bracing and alignment. The walers are easily attached to the backside of the HD 1500 Forming Panels. Also visible are shearwall brackets which support the gang.
This is the wing wall poured in its plumb form. The angled wing wall starts at this elevation. Visible along the rake is the a steel angle from which hinged corner forms of the steel-ply forms were attached to pick up the break line and commence with a 30-inch, 12-degree from vertical starter wall pour.
In this picture, the first pour for the leaning wing wall is ready to go. The inside wall gang is fully built. Visible are the elements that make the inside gang able to handle the condition of leaning 12 degrees from vertical, Versiform walers installed behind the forms parallel to the rake provide horizontal alignment, with Symons Soldier Beam Strongbacks at 4 feet on center braced with Tilt-Wall braces to a specially poured 12-inch concrete mat for attaching the brace foot plate anchors and handling the horizontal forces.
This is the inside leaning wall gang fully built and braced. Installation of this inside gang was done section by section with the use of a lift bucket. It started with the bottom row of HD 1500 Forms tied in place to the starter wall at the precast tie locations. These locations were cast into the starter wall pour.
