What Florida license is required for a precast manufacturer to self-perform the installation as a subcontractor?

I am managing a precast concrete plant where we produce building components such as precast concrete elevator shafts for 4 and 5 story wood framed multi-family buildings. We have crews that have installed hundreds of these shafts in Florida while working for our previous employer who held a class A GC license. What license is required to qualify our new employer to self-perform the precast installation?
