This is a closer view of the tilt-up construction process, showing a concrete contractor lifting a wide tilt-up panel into position. For more information visit www.tiltup.com or www.generalcontractor.com
They removed the strongback while the panel was not vertical or set , good way to have the panel break . wait till it is set in position, you made it this time, next time maybe not so lucky.
What they did was fine, they would have put extra steel in the edges plus all the lifters are layed out on the heaviest part of the panel at the top, strongbacks are mainly required for the ground reaction tilt to stop it from folding.
