Interesting and unfortunate.As we are filling an area we always like to get the loaded trucks up on the fill lift not only to help with compaction but perform an unofficial proof roll each time. This will tell us how the fill is really being compacted as the nuke box can lie from time to time with bad data. A loaded 85K lb tri-axle rolling over a lift is like spandex and innocent children - none of them lie. Dirt tech observing.

Side note on this project. We had a GPS model built early on so we would have it ready when we started. GC had their surveyor come out to set us 5 control points, pretty standard procedure. Well not this time. The surveyor the GC hired could not calibrate the original surveyors control points - some were out 3-4 tenths horizontally and even worse 3-4 vertically.
Hired surveyor worked on it for 2-3 days and quit. After talking to him he said he was basically so busy with good paying work that he didn't want to be drug into a mess created by someone else and be liable. Can't argue with that.
So we had to resort to old school methods or rather the GC did. Our contracts state we need 5 control points provided by a licensed surveyor paid by the GC for our layout. Since the GC couldn't provide that we pushed it back on the GC to perform all layout.
Yeah it turned into a cluster...oh well.
One thing different with Earthworks than GCS900 is that the calibration file must be imported into the site and published to the project library, and then to the machine. I understand that it can be exported to the machine remotely, but we haven't tried that and just use a jump drive. With GCS900 we could have the design loaded and then just import the calibration file on site directly from our data collector. I now need to bring my laptop and go through Trimble Business Center.
Are you handling this the same way, or do you have a better method?
