thanks again guys for your helpful input. I'm going to go for trig leveling using my robotic S7.Will probably hand book to start with although I did j...

This his raised some very interesting comments. Many, many thanks. I already have a robotic Total Station so that looks like the best way to go for no...

Hi guys Thanks for the answers. I work solo and haven't done a great deal of leveling to date. Mostly my clients have been happy with a local site ben...

Thanks Jitterboogie

I have the data collector fixed onto my pole just below where the height marks readings are on the pole. I always try to have the readings facing me a...

Jim -?ÿ A jig is a good idea but all the steels were slightly different sizes . My steel tape measured their sides ranging from 202mm - 210mm. But you...

Christ - I though about using a mini prism and I would have preferred to use one. I assume your plan would be to do angled offsets? I just don't trust...

According to Korec my Trimble S7 has a "general purpose" laser, not a HD laser. That's why I used targets - they advised it would be more accurate and...

That's a good point Paul - thanks. I curious how wide a target you need to get a reliable reflection. The thickness of the steel flanges were 11mm (0....

using pre made targets would have been quick to put up but drawing my own cross hairs mean that I could locate the corner from my shot. All cross hair...

surely the constant for reflective tape is zero?

don't have a scanner

I am not plumbing the steel columns. All I need to do is give x, y, and z for the tops of the columns.

I don't have access to the tops of the steel columns as there is a roof above them. I'll be surveying from below the tops of the steels - I don't thin...

take your time. Pull the drill up now and again to blow the dust out. Also start with a smaller bit like 1/2" or 3/8" and then progress onto your 3/4 ...
