They should be firmly wired to the reinforcing steel so that they won't be displaced during the placing and vibration operations. You should not attempt to wet-set these inserts for any reason.

• They should be accurately located vertically, horizontally and for depth.
• They should not be placed closer than one foot from any edge or opening.
• They should not be placed in line vertically with the brace inserts that might interfere during the panel setting.
• The concrete should be vibrated well around the inserts.
• There should be a positive method of preventing concrete from entering the attachment portion of the insert.
• If there is need to move a lifting insert, consult the erection engineer for proper relocation.

The Federal OSHA and American National Standards Institute use a two-to-one safety factor inclusive of all loads for Tilt-Up, and a four-to-one safety factor for precast lifting inserts. Bracing inserts do not have a standard, but manufacturers and designers normally Up one-and-a-half-to-one or two-to-one.

• Make sure all hardware is in good working order, unbent and free of cuts and defects.
• If coil bolts are used, be certain all bolts are unbent, have washers, and penetrate clear through the coil.
• If hardware is used that bears on the panel surface, be certain it bears well, using grout pads if necessary with exposed aggregate or textures.
• Any strongbacks or added reinforcing specified for lifting must be correctly in place at the time of the erection.
• All cables, hooks, swivels, and bails must be free to rotate in the line of action or the load.

The inserts should be placed within one inch horizontally and vertically, and within ¼" for depth.
