Drilled Caisson/Rock Socket Costs

Drilled Caisson/Rock Socket Costs

Drilled Caisson/Rock Socket Costs

(OP)
I am doing a project for a DOT in the Pittsburgh area.  I am looking for costs for a 9'-0" drilled caisson rock socket (20' in length) and a 10'-0" drilled caisson (about 40' in length).  I found information for smaller diameters but would like to know how much the costs increase for the larger diameter.

Thank you!

RE: Drilled Caisson/Rock Socket Costs

In the Toronto area, 1998 Canadian prices

For 6ft $550/ft
For 7ft $700/ft

Sorry none for 9' and 10' but you can compare mine with yours.

Perhaps call a drilling outfit in your area.

RE: Drilled Caisson/Rock Socket Costs

I agree with Mike80's price for the Midwest.  Typically we don't do large diameter rock sockets - six feet diameter is large (and adequate) for most work in the Midwest.

I've seen smaller diameter rock sockets running around 500-900 per foot for 30" to 48".

You might want to look at some of the information for coastal states.  Those states with large bridges or the like which may require large diameter work (presuming they can find bedrock!) might have information for you.
