FAA 1A Specs
Posted by fbsurveyor on October 10, 2012 at 11:03 pmOh hey got a collegue asking me about a type of survey he would like to bid on. He says it is and FAA type 1A survey. I’m pretty sure FAA stands for the Federal Aviation Administration but don’t have a clue as to what the 1A (one-A) might represent. He seems to think the surveying portion has something to do with accuracy standards. Just curious if anyone might have run across this before and can say what that represents or how he can find out. I’m sure he would appreciate the advice or help that anyone could provide. I didn’t ask but have a feeling he has tried a “google” search.

Maybe this.
Very likely the point to be surveyed is the top of a cell phone transmission tower, or some other kind of antenna.
I believe the FAA publication in a [msg=156443]prior post here, requesting monument details[/msg] will be helpful. FAA How to manual for airport surveys.
I myself have done a couple of FAA 2C letters and I agree with the link above showing the requirements for FAA letter. The vertical requirement for 2C was +/- 20′ . It is a letter and then as a surveyor you determine the actual elevation of the ground relating it to a set of plans for the Cell Tower or Radio Tower height and then provide that letter stating the approximate height of the tower is X related to M.S.L. and provide it to your client certifying it by signing that letter.
Good luck with the project. When we did our first one we asked for an example letter and received one from either our client or the FAA, I can’t remember which to base our letter on.

Chad W. Carpenter, RLSI do a lot of FAA 1-A’s for AT&T in Hawaii. AT&T usually requires more information that what is need by the FAA, mostly for their own design purposes. I can send you one to look at if you need it.
Check out the AC-16, 17 & 18 specs for info on standards and check into AGIS. Depends if its airside or landside.
Hey thanks for the info. I believe my colleague is from the Sebastian area originally or possibly West Palm Beach? I believe I remember him mentioning Sebastian. He now resides in Fernandina Beach, Fl. You don’t have an example of the letter that you can send by some chance?
If he doesn’t, I do. Send me your email addy and I’ll get you a copy of the letter that they wanted for our cell tower work.
We’ve done a lot of FAA work, but we usually do pavement (runways, taxiways, tamaracks, etc.) and they hold those to within 0.04′ at every point, both horizontally and vertically. And the ones that are high on the final concrete, they force them to shave it down to within 0.02′.
But the transmission towers might have relaxed standards. Haven’t done any of those.
Yeah apparently the towers do which I personally have never dealt with yet but I have also worked with the contractors pouring the runway concrete and they can have quite a hard time meeting the strict .02 foot verticle requirements. It can make for a long day.
A copy would be most helpful. My email address is [email protected]. Thanks
Hey that would be great and appreciated. Interesting screen name. I bet there’s a great story behind it. If you can send it to [email protected]. Thanks a lot.

Any way I could get a copy of one of these 1A letters that I can refer to?
for a little more depth…
Mr. Crawford is correct, but perhaps this is the etymology of same:
Well, nobody has asked for an faa 1a certification letter example in over 6 years so here goes.
I just got an faa 1a request and I am researching it. Does anyone have an example they’d be willing to share?

I was asked to do one about 6 months ago. They wanted the letter at the same time I did the boundary partitioning out the 8 acre tract but they told me that the tower people would decide where the tower would actually be located. I refused to do the 1A survey until they actually had a footing in the ground. I haven’t heard from them since.
Apparently there is some grant money available this year for Counties to upgrade their radio system. The County I live in is looking at doing the same thing.
@jaro I just sent on out this AM. In an effort to prevent any issues I noted that the pole location was “Proposed” and not constructed.
