The next step is to install embeds and inserts.
Embeds are pre-fabricated steel plates with lugs that are cast into the panel to attach it to the footing, other panels, or the roof system, or for attachment of building accessories after the shell is completed. They can be attached to the side forms if they are on the panel edges, or they can be wired to the reinforcing.
Inserts provide the attachment points for lifting hardware and braces. They usually are sized by the supplier, who also should furnish engineering drawings showing insert locations. Install inserts according to the manufacturer's recommendations.
If there is a field change in panel size, opening location, or other conditions, the insert supplier should be contacted to confirm the location and selection of hardware.
