Normally, modern buildings have reinforced concrete structures embedded and are built on a reinforced concrete foundation. This dramatically simplifies the grounding system construction. The effective regulatory documents recommend using mostly natural ground arrangements.
GOST 12.1.030-81 "Electrical Safety. Protective Grounding. Neutral Grounding" is still applicable to the electrical equipment grounding. As applied to the lightning protection systems, much more complex situation exists, since their grounding should pass a large electrical charge within a short period.
