Can I do High rise stakeout (ftgs,cols,walls,slabs)using the latest GPS machine (which brand?) and obtain the same accuracy (+/- 5mm)of a Total station?

two of my friends are working at ground zero,one is doing tower four Ā and one is on the freedom tower, they are working for the steel erector, they have been using Ā gps, Ā the General contractor has there own surveyor's, Ā they are using traditional Ā skyscrapper ( or high rise surveying Ā procedure's , throwing the lines up from the street and also bucking in on target's( on other building')s. Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā
Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā They were usually hitting each others lines pretty good Ā (no more than .05 difference) Ā however , It's getting tougher and tougher ( once you get above 700feet). Ā I know their up much higher on the freedom tower now. Ā if you have a good gps Ā system, you should be able to do the job, Ā
try my method for high rise building it will works well
Hi Kadmous El Khatib.
How is that?.
Hello Antonio,
Thanks for your reply. In my reply on April 29 I wanted to share a document that I believe can be the answer about this question, the name of the document is correct but I didn't put the link. This is the link

Hi, I just want to share this doc.

I'll try.
With my Robotic Total Station I can place on the ground: footings, Columns, walls...; on the forms: slabedges, cols, walls.... everything with good accuracy (5 mm more or less). My question:
Can I do the same with the latest GPS machine?. Thanks for asking.

perhaps you should be more specific
