The project is for a pressurized pipeline that will go between 5 ft to 25 ft below ground surface (depending if they do HDD or trenching). The pipeline extends for about 6 miles, so there is a large variation between materials along the plan view.

I am looking to obtain some used lab equipment, specifically a soil Unconfined Compression machine. I've looked at Ad-Tek and worked with them in the past but they do not have anything used in our price range. I'm located in California if that is applicable. Does anyone out there know where you...
Ron: I'm not the decision maker in the project, the solution is pretty set in stone and calculations have been done including pipe bedding and the pipe filled, hollow, etc. I'm the field engineer on the site. I think your concerns and recommendations are completely valid and quite well though...
@Ron, we have enough data for the insitu densities. Our goal is to backfill so the same stresses are felt just below the pipe as before to minimize any movement upward or downward. By applying the same amount of stress to the peat just below the pipe, the worry of settlement is negated. Do you...
I'm currently working on a project that requires knowing the density of insitu peat and being sure to not apply too much overburden to the native soils. We are installing a drinkwater pipeline roughly 6 feet below grade that traverses an agricultural field. The agricultural field consists mostly...
