Design forms to support a flat slab floor $9$ in$.$ thick of normal weight concrete using Douglas Fir Larch forming members and steel shoring. Since forms will have continuing reuse, do not adjust base design values for short term load. In this case, assume $1-1/8$ inch Plyform Class $1$ for the sheathing.
