GFCI receptacles and 120V circuitry

[Isaiah]

On a power plan drawing for a new office building, they’ve routed GFCI receptacles on the same circuitry with general receptacles. If I’m not mistaken GFCI circuits need to have a dedicated neutral conductor. But I can’t remember the reasoning behind it

GFCI breakers cannot share neutrals. Receptacles can share neutrals on their line side but not on their load side.

If it's just GFCI receptacles, as long as you don't try to share the neutral from the load side, they should work fine. Assuming the general receptacles are ahead of the GFCI, or feeding the general receps from a single GFCI load side will work.
I don't see the need for more than one GFCI receptacle. If there are different areas that need GFCI, a GFCI breaker would be the way to go.

There are up to 2 GFCIs on a circuit along with a few general receptacles. They come directly off a 20A, 1P Branch CB in a lighting Panelboard
Both GFCI and general recepts share the same neutral. No problem, right? I just wanna be sure before construction installs it
Many thanks

Reiterating what others have said: A GFCI receptacle has _line_ and _load_ terminals. The _line_ terminals supply power to the receptacle. The _load_ terminals let the GFCI provide protection to downstream loads.

You can share neutrals connected to the _line_ terminals, supplying power to the GFCI.

You cannot share neutrals connected to the _load_ terminals. Any neutral connected to the load terminal must be dedicated to GFCI protected loads, along with the corresponding 'hot' conductor.

As long as construction doesn't touch the 'load' terminals you can just mix GFCI and general receptacles.
