I am a geotech engineer being asked to provide passive earth pressure parameters for the design of building foundations. Metal building supported by column footers. Is it conventional to use passive earth pressures for lateral loads on foundations, or is the lateral load typically addressed...

I have a question regarding best practices for lab testing. My lab will sometimes have several people working in the lab together, and they may run a proctor together. I don't know how they split up the work, whether they take turns beating each point, or whether the same person always beats...
General question regarding using the results of triaxial testing on remolded samples for slope analysis. We are generally testing silty sands or sandy silts. Not really any clays to or even elastic silts in our area. The lab we use often reports effective values in the neighborhood of 34...
I have a small project masonry project for which 1 set of 3 mortar cubes were made and tested for compressive strength. Low 28-day strengths were 600 psi for Type S. There is only 1 set due to size of project and contractor not calling for testing. Can the prism method by done (ASTM C 1314)...
Looking for any data or experience working with low unit weight soils. I drilled a site for a new project which will have earthwork cuts and fills. We ran Standard Proctor tests on two bulk samples and got very low unit weights, 76 pcf and 83 pcf with optimum moistures around 30 percent...
I've seen it referenced several times here, but have not been able to find a copy. Looking for the following paper
"Dynamic CPT for Test-Pit Field Investigations: Experiences with Sowers' Cone Penetrometer" by L.E. Robinson that provides several equations to correlate Sowers' DCP blows to SPT...
