The FAA still shows the heliport as active. They also show the location as "Estimated", so it's likely to be in those office buildings nearby. But this wouldn't be the first time nobody bothered to notify them when a private airport/heliport went away.
Raytheon no longer has offices nearby, and in any case, the location given for this heliport is a residential neighborhood.

This private airstrip has been deactivated at this location. 29NC has been reassigned to a private strip near Hillsborough, NC.
