Any civil engineers here who could help me out by providing me with the turning radius you use when laying out a circular drive for a semi to turn around in?
I need to lay out a drive that would allow for the truck to approach the circle, drive almost all the way around it and then stop and back up towards a building front.

Go to the Library and find "Architectural Graphic Standards" or a similar reference book. It will have several alternative choices. I'm sorry I'm at home and not in the office or I would look it up for you.

You might go to your local library and see if they have a copy of an "Architectural Graphic Standards" The issue I have does not show exactly the situation you are describing, but I think that there is enough info. that you can adapt to answer your question. These publications are expensive (last time I checked $250.00) so if you don't do a lot of design work, the public library is probably your best bet. Hope this helps.
Thanks for the tips on the library source. I checked with google and came up with this link that indicates 50' should suit what I am trying to accomplish. http://www.thetruckersreport.com/turning_radius_info_for_eighteen_wheelers.shtml
Edit for typo, thanks shep!!They can't get your Goat if you don't tell them where it is hidden.

Find out whose trucks are going to be using the drive.Call and ask them for specs.They'd probably be happy that someone is asking, rather than just expecting them to make use of whatever is decided...

It would be impossible to tell , this is for a winery so different trucking firms and trucks. Owners tell me trucks really aren't as big a problem as the stretch hummer limos that pull in.

50" would be for a pretty small semi <G>
I've screwed this one up too. I just didn't want you to make that mistake in your proposal.
The reason I did not post the turning radius of simi's is that the radius varies. The major/outside radius for 55'-0" rig is 50'-0". The inside radius varies at different points along the arch. anywhere from 28'-0", 24'-0" & 22'-0" to accommodate the trailers trailing wheels. I'm not sure that I could describe it without raising more questions than I answered. As they say, a picture is worth a 1000 words.
Thanks very much for the further explanation. Gave me a bit more to think about. I need to lay out an approach for a building that will work . Room isn't really much of an issue since the site is huge. What I have now is a landscaped signage area that I had planned on being the center of the "doughnut" so if I keep that to say 20' outside radius a, which is then the inside radius of the turn and make my outside radius 50' that should work. Roadway looks like I could get by with an actual 30-33'width .

I'm not much help but we have a truck driving school here where I live
When I worked as a school counselor I took kids to visit the school and I talked to the instructors and they were very knowledgeable about everything related to truck driving
Good luck!
Also double check with whoever provides the local fire protection. I was told by my local planning agency that I needed to provide a turn around for a fire truck at the end of my 150' driveway. The fire department told me what it was but I don't remember at the moment, but it was certainly a lot more than I had originally intended.
Good Point. I am going to have the archy take care of all of the actual details on this. I am working as a liaison between the owners and archy at this point.

I don't mean to beat a dead horse but be careful with assumptions. Though not brain surgery, the tracking of the trailer wheels can be tricky and can fool you. It's a lot easier to make changes/corrections with an eraser than with a jackhammer.
Also noted. As I just posted above the archy will actually be responsible, I am acting as a liaison right now.

As a holder of a CDL A what ever you are told will not be enough.
Fourty acres.
Heard it in a song.

Forty acres.
Back in high school working on the farm I'd occasionally get a tractor stuck and the farmer would always say, "forty acres to turn around in and you picked this spot!"

Semi-trailer drivers have a huge advantage – their excellent maneuvering skills and impressive turning radius! Your ability to drive such a large vehicle with such precision and agility in tight spaces is simply amazing. You are true masters of the road, making safety and efficiency their prerogative!
