Auger Cast Pile Installation Clearances
(OP)
I am running into some problems with a project involving auger cast piles. This involves a new pipe rack we have designed that will be placed within an existing refinery. There are many places that have either existing foundations nearby or existing piping running about 1'-0" above grade.
The geotech report called for piles to be used so we had no choice in that matter. We decided to go with auger cast piles with the thinking this would be the best option for installation with existing objects nearby.
The contractor has expressed concern with being able to install these piles as he wants a 4'-0" diameter safety cage around the auger during installation (piles are 12" dia.). This cage goes into the ground approximately 1'-0". This obviously will not work due to nearby interferences. My question for you all is...is this typical for ACP installation? Do you know of any alternatives I could offer to work around existing foundations etc.? See attachment for details. Thanks...

Good point ! But I have not seen any other place where a safety cage could be mandatory. If it's not, then they just have to remove the safety cage.

Come to find out, the ACP contractor was acutally concerned about getting his rig into tight spots to drill the holes. Have any of you ever seen auger cast piles installed with a rig that has an articulating boom on it (for hard to reach spots)? I'm looking for a piece of equipment that can sit on top of an earth dike and drill holes on the slope. If so can you provide any links or other information? Thanks...

How does this get to be your problem? Shouldn't the ACP contractor be figuring this out?

The reason I'm in this situation is because the guy who did the engineering left our company once the package was issued for construction. I was not involved with this particular project in the design stages and was trying to keep the client happy while also finding a solution to constructability problems.
After talking with the contractor some, it looks like we may have worked through any issues that he had. Thanks again for all the input.
