Help Please - professionally-impaired coworker

So I have this professionally-impaired technician in my office. He has been with us for about a year. He has most all of the same professional development training classes I have had, along with professional explanations from me along the way.

He doesn’t really get the concept of professional boundary analysis even if I try to explain it over and again. He seems to treat me as though I have less intelligence than him because he has all of the electronic savvy. I tell him that his final product has to be to a level that anyone that does not have the same software can understand. He argues that everyone should be able to do calculations with data-collectors and understand the software enough to figure it out.

A while back he ran in a control network for a DOT project and published the data. (no I can’t run all the CAD software so great and don’t understand that Trimble Business Center software so well. But I pulled out my calculator and checked his information against simple calculations. He didn’t provide all the metadata needed, but he had his lat’s and longs and his final “project coordinates”. I ran through running a number of scenarios to get the same data and see if I could figure out what he did. I was able to run the lats and longs through the NGS data-site that spits out State Plane coordinates. I was able to convert to feet, and figure out an average grid scale factor for the project. Matching the exact same number shouldn’t matter that much. I also got an elevation scale factor, and ran ran through the math to get my own “project coordinates”. I then inversed distances between my coordinates and his. The bearings were right on. But I could tell that something was probably wrong with the combined scale factor. I rechecked all of my calculations one by one, and made certain of my inverses. I checked what his scale factor was to go from his spc distances to get what he got. We had a tenth difference in only a couple of hundred feet and, of course much more in 1,000. I talked to him about it. I told him that he should be showing all of his metadata and that there was something clearly wrong with his scale factor. He kind of looked at me with his snooty “I’m-smarter-than-you” attitude, and said “no offense or anything, Tom, but how do you know?” I told him I could show him exactly my calculations, and where is his metadata. I was getting a bit perturbed. I told him he better go out and measure some distances between actual monuments and check his work. His stuff was off. Another survey firm had already used his data as well. This did not go well.

He thinks he’s better than anyone else because he can run circle around everyone with his software, and it’s incredibly difficult teaching him good survey concepts. (I once had to get after him for using a Section corner as control that he had found by “beeping” it under the asphalt and tying in his beep. He then ran boundary off of the electronic data.) All the engineers and a lot of the nonsurveyors think he is extremely fast and more efficient than anyone else. He has my boss snowed as well as many others.

This guy is licensed, by the way.
