Typical Gantry Loads

[Eugene Lim]

Hi. I am a geotechnical engineer. I received the following sketches from the structural engineer for 2 options of highway gantries. I am estimating pile lengths, without estimated loads from the structural engineer. Can anyone give me a rough idea of how heavy these gantries would be? Rough estimates from those with experience would help be greatly!

In my experience with the cantilever type (similar to the top one) - a few tonnes typically.

@Eugene Lim... I don't think a rough estimate of the gantry weight will do you any good, wind could be the dominant design load.

You should ask the structural engineer to provide you with the design load; the structural engineer may even be expecting the piles to support tension?
