The office kept sending out 10’ x3/4” ground rods, they worked well along with the two bolt ground clamps in the dumpster! LOL! Never drove one where I couldn’t bury it with an acorn clamp!
 
What is the cabinet on the right.
appears maybe the SEC's pass through it then through the wireway to the newer equipment?

If so they wouldn't like having that much service conductor inside the building around here. General rule is no more than 5 feet of service conductor, but can allow more in some situations, though this likely would not be one of those situations.

Or am I looking at it wrong and is top fed (through the back wall) and the wireway is the load side conductors maybe?

Was initially thinking it maybe was meter/main/loadcenter, but not much of a load center for 400 amps, that door maybe access for fuse type OCPD?
 
And that GEC to the rod would need to be #4
Take a look at 250.66 (A).

I do think it is subject to damage laying on the floor like that so IMO it needs to be protected.

250.64 Grounding Electrode Conductor Installation
(B) Securing and Protection Against Physical Damage. Where
exposed, a grounding electrode conductor or its enclosure
shall be securely fastened to the surface on which it is carried.
...
(2) Exposed to Physical Damage. A 6 AWG or larger copper
or aluminum grounding electrode conductor exposed to physical
damage shall be protected in rigid metal conduit (RMC),
intermediate metal conduit (IMC), rigid polyvinyl chloride
conduit (PVC), reinforced thermosetting resin conduit Type
XW (RTRC-XW), electrical metallic tubing (EMT), or cable
armor.

Yeah most people just think #6 to rod, but they forget the installation determines size as well. Here is the complete section:

250.64 Grounding Electrode Conductor Installation.
Grounding electrode conductors at the service, at each building
or structure where supplied by a feeder(s) or branch circuit(
s), or at a separately derived system shall be installed as
specified in 250.64(A) through (F).

(B) Securing and Protection Against Physical Damage.
Where exposed, a grounding electrode conductor or its enclosure
shall be securely fastened to the surface on which it is
carried. Grounding electrode conductors shall be permitted to
be installed on or through framing members. A 4 AWG or
larger copper or aluminum grounding electrode conductor
shall be protected if exposed to physical damage. A 6 AWG
grounding electrode conductor that is free from exposure to
physical damage shall be permitted to be run along the surface
of the building construction without metal covering or protection
if it is securely fastened to the construction;
otherwise, it
shall be protected in rigid metal conduit RMC, intermediate
metal conduit (IMC), rigid polyvinyl chloride conduit (PVC),
reinforced thermosetting resin conduit (RTRC), electrical metallic
tubing EMT, or cable armor. Grounding electrode conductors
smaller than 6 AWG shall be protected in (RMC),
IMC, PVC, RTRC, (EMT), or cable armor.

No you're looking at it right. That wireway is feeding the metrr main load center with one set of 500s that cabinet to the right is an existing end box for the existing service in the building we added this setup for a solar installation

And yes the door is the access fuses on the load side
