Setting out Steelwork

[mac1992]

Any advice on the easiest/most accurate way to set out steelwork? This includes getting the orientation of the bolts correct.

My idea of extrapolating co-ordinates through at either end of gridlines and creating timber goalposts with a hilti nail, then stringing a line through each goalpost worked, however was very time consuming and restricted access.

Further tips would be greatly appreciated.

The method you described is called "batter boards" in the US. It is still the most common and accurate method of establishing building lines, given the training of most construction crews.

Hire a surveyor to do it.

A lot of Contractors do their own layout and many use total stations to do this. On one of my last projects, Ellis-Don actually had a robotic total station (first one I'd seen). The station has a receiver and the prism had a transmitter (or vice versa) and 'the machine' followed it and took the readings.
