Column box or shuttering for columns is made of plywood sheets or steel sheets fabricated with adequate stiffeners. Thin films of oil or grease should be applied to inner surface of the shuttering to enable easy removal of the column after the concrete hardens.

Precast concrete walls are constructed by casting concrete in a reusable wall mold or form which is then cured in a controlled environment, transported to the construction site and lifted into place. The main function of the precast walls is to speed up the construction process.

Casting of foundation would mean completion of all substructure work which is below the ground. That would mean finishing excavation and concreting of all foundations and the work for superstructure above the ground to commence. This is also referred to as completion of plinth work by some builders.
