Building steel

[hhsting]

If I have building steel in compliance with NEC 2014 Section 250.52(A)(2)(2) hold down bolts that connect to concrete encased electrode connected with steel ties then do I still need grounding electrode conductor to the concrete encased electrode?

250.50 Grounding Electrode System. All grounding electrodes
as described in 250.52(A)(1) through (A)(7) that are
present at each building or structure served shall be bonded
together to form the grounding electrode system. Where
none of these grounding electrodes exist, one or more of
the grounding electrodes specified in 250.52(A)(4) through
(A)(8) shall be installed and used.
Exception: Concrete-encased electrodes of existing buildings
or structures shall not be required to be part of the
grounding electrode system where the steel reinforcing bars
or rods are not accessible for use without disturbing the
concrete.

The language in 250.68(C)(2) would permit the GEC to be connected to the building steel.
