Boulder rubble wall design
I'm looking for some guidance on evaluating an existing boulder/rock rubble wall. What are the critical components and requirements in terms of height vs. thickness, slope, toe conditions, backfill type, and geofabric/drains?- mad2323

Deep Foundation Cost Comparisons
I have a site that will have 7-feet of dense gravel fill over 6-feet of soft sands (liquefiable) over native gravel at about 15-feet total. It may be hard to auger through the fill as it has cobbles. I'm considering micropiles, drilled shafts, geopiers, CFA piers, or whatever else would work...- mad2323

Settlement of sand under fill
I have a site that will have 6 ft of fill placed over 6-feet of loose fine-grained sand with N value of 3 with water at the ground surface. I have looked at a schmertmann approach and came up with less than 1 inch of settlement but I'm not buying it. Any thoughts out there?- mad2323
