Fun day. In broken spanish, the form board guy tells me that my warehouse stakeout - 6 corners with 5 foot offsets - is an inch long. Finish staking the last of the shop building, drive over to the warehouse and set up on the SE corner of warehouse. Shoot the NE corner. 230.002' on the readout. Start questioning the fb guy about how he measured it. Well, he has a 300 foot steel tape. Did you tension it? No.Calibrated lately? No. Correct for temperature? No. OK, I think I will stand by my measurement. I have been taking advantage of our local baseline and rotating the total stations to the dealer for service on a regular basis. Just for grins I might hit the baseline tomorrow.
I used the shiny new GPS system to set hubs and then went back with total station to set the tacks. 98% of the time, the tack fell on the hub. 2% of the time we had to adjust the hub. Seemed a lot faster way to layout the building. Very happy with results.
This afternoon, got a request for survey in a railroad block which has construction fairly well established by a court case in 1957. Will be checking in corners established by the court over a 192 square mile area to make sure my section is properly established. Found out today that the General Land Office wants gradient boundary established due to excess in the section and section bisected by a statutorily navigable river (if you can call it a river). I'm pretty sure today's quote is the largest I've ever generated and I am afraid they're going to have sticker shock. Not sure if the land is worth the cost of the survey. The two oil wells drill previously have been dry holes to my knowledge. I hope they bite, though because it will be a great survey.
Not to be a bummer, Andy, but is an RPLS licensed and authorized to determine gradient boundary in Texas??
i hope you get the job. sounds like fun.
have you done any gradient boundary or taken a seminar?
sounds like something to get some advice on from an LSLS at the least. finding qualifying bank ought to keep you busy.
good luck and have fun w/ it!
p.s. sorry you missed the TSPS bash w/ all the crazy women w/ not much on 😉
The project is to prepare field notes to submit to the GLO for patent. Mr. Schumann is an LSLS and it would be the second set of field notes we've filed this year if we get the job but only the third LSLS project I've worked on in three years. Not a whole lot of LSLS work out there, but every once in a while. I think I have taken the gradient boundary seminar at least 3 times not to mention studying it at Tyler. This would be my first time helping with a real, on-the-ground determination.

An LSLS can file stuff in the land office and work for the state's interest. Everything else can be done by an RPLS, including gradient work. Since the adjoining upland owner isn't the state, you're simply locating his boundary.
Now, Ben Thompson says that RPLS can do them all day long, unless minerals are involved. For me, there is no difference, even when minerals are involved.
Andy and I have been at a gradient seminar together. Qualified banks down there are pretty easy to spot. Over in my neck of the woods, they're a bit more difficult due to mostly bluff banks.
