When you call out an Iron Pipe, do you call it as inside diameter (ID) or outside (OD)?
In my neck of the woods we don't use pipes anymore, but find them all the time. I know when I worked in California, we found pipes all the time. Sometimes even with a YPC inside it. Anyway... I had always in the past thought that a surveyor should measure outside diameter of an Iron Pipe, but I am coming around to saying that it should be inside (largely because that is how it is measured at the hardware store). I guess it should always be stated, at this point but what is your standards at your office?
Standard is ID because that is how pipe is sold, BUT I always state what was found.

General rule of thumb: pipe is measured by ID, tubing and rebar is measured by OD. But we have to realize surveyors aren't plumbers or pipefitters. Most "Found 3/4" pipe" notes I follow are in reality 1/2" (ID) gas pipes; common use for surveyors for a number of years back in the day around here. Surveyors have a tendency to report the OD of pipes, bars, pins and axles. Is it wrong? nah...we generally just report what we see...as it should be.
Im a big fan of more info is better.
FIP
SIP
Are too vague.
Fd. 3/4" conduit. Is descriptive.
Fd. 3/4" id, 1" od pipe, is even more descriptive.
I'm just a fan of "more is better".
I have done this:
"Fd 1/2" rebar, 20" deep, set 1/2" x 12" iron pipe, over the rebar, to bring it closer to the surface."
FIP and SIP are poor.
As long as you dont end the description with 'N30 23 12W, 0.21 feet from true corner' we'll probably get along well...

Yeah, but it can get confusing.
The work I do requires me to identify a lot of aerial electrical lines and utilities. Although most poles nowadays are power poles; there are a lot of just telephone poles out there also. And there are joint-attach poles. When I set a 40d nail in a pole for a reference I can't get too descriptive without maybe confusing the next guy.
"Set 40d nail in SW side of PP at knee height" to me is probably understood better by our brethren than "Set 40d nail in Class 4/40 SPC treated joint-use 12.5 kV distribution structure".
U.P. = utility pole.
as far as I know all pipes and tubes are known by their ID... the OD is a function of the wall thickness.
unfortunately some surveyors don't know that and misidentify.

Oh I don't know, a pet peeve of mine is trying to find something where the notes refer to all the poles as electric or phone poles when that isn't the case, I at least will say "wood utility pole" if I don't want to lie about it or don't really know. Of course your example description may be a bit much, but writing a description that your audience can understand that has a bit of detail never hurts. If your ONLY audience in writing your sample description was electric utility employees then it is fine.
Point is, I think there is a lot of "field notes" shorthand that makes it onto plats that probably shouldn't because found IP could be iron pin, iron pipe or who knows what, you knew at that time, BUT even you probably don't know a few years later, let alone anyone else. We aren't hand lettering that anymore, type a description for goodness sakes, it really won't hurt you and is the professional thing to do!

Dang.. the drafters at my company get upset if descriptors are longer than 4 or 5 letters.

I prefer to use the outside diameter (and call it such) as our statutes describe monument requirements by outer dimensions. It also helps when buyung aluminum caps thst fit over the pipe. If i needed to fit a tee or valve i would use the plumbing numbers...
PP or guy pole or guy stub. Dang few telephone poles left in this area. Some telephone marker posts, though. Harder to find are telegraph poles.

Just be sure the OD is larger than the ID or the hole will be on the outside.

I call out the nominal ID. The actual ID is slightly larger, e.g. a 3/4" Schedule 40 iron pipe has an ID of 0.824".

darn I hate it when that happens
Haven't we discussed this before?

There are still a few "open wire" telephone lines around here, but are all probably dead. One I know of that is still active is a 2-pin line that runs a half-mile from the house to the barn at the Braum's ranch in Rosedale, OK. They left it up as a good memory and is still terminated on each end by a phone you would probably recognize.
It's owned by the ranch and not the phone company anymore. The hay hauler drivers still call the house from the barn with the phone if they get there and there's nobody to unload them.

A 1/2" iron pipe, as sold in stores today, is actually 5/8" inside diameter.
Ah yes...I too remember when telephones were attached to the wall instead of some kids' ears.
