(57) An insert for lifting and leveling a precast concrete slab is provided. The insert includes a sleeve that extends through the concrete slab and has two distinct threaded portions on an inner surface of the sleeve. This configuration allows a lifting bolt to be positioned into an upper end of the sleeve to lift the concrete slab, and a different-sized leveling bolt to be positioned in the sleeve to selectively elevate or raise part of the concrete slab relative to a ground surface.
