im a student studying Land Surveying in London, i was wondering if any land surveyors could give me the best and most accurate way they would set out the structure of a motorway gantry which is 62m long. The two pillars on each side have to be constructed within a +/- 2mm specification. The task is set out in a way that one side of the motorway will not be available to the surveyor. Which is the best way of actually setting out the correct position for the structures to be built in and be able to line up within 2mm from both ends. The motorway gantry has been pre constructed and will be put onto the motorway in one night. How would a surveyor set the positions up for the bolts? the only thing i got is setting out from a known coordinate on a local grid. What is a professionals view on this?

thank you for your time.

The Timezoner movement with Replica Watches its signature ceramic worldtime bezel made its debut in 2016 with ref. IW3905 – the brand’s Replica Rolex first in-house manufactured flyback Tag Heuer Replica chronograph with a world time complication. This new Spitfire design cleans up the dial a great deal by omitting the chronograph and red-tipped 24-hour hand in the center of the dial but adds in an altimeter-style Replica Designer Handbags 24-hour aperture that we haven’t seen on an IWC Pilot since the UTC TCZ an excellent, but lesser-known reference from 1998
