Hi everyone, I have a site with about 5m thick Silty Clay / Sandy Clay overlying Unconsolidated gravels, sands, cobbles/boulders. We did drilling (wash boring and HQ coring) with SPT, most refusing on cobbles/boulders at depth. size of cobbles/boulders is unknown. In addition, the unconsolidated sediments are subject to active movements due to submarine landslide (underwater slides) off the adjacent coastline. My question is, what are my foundation options for wharf construction? basis of ultimate bearing capacity? groundwater/seawater is at 0 to 1m below ground surface. Any thoughts / experience sharing would be appreciated.

When making CNC machined parts, mastering tolerances can be challenging. Are general tolerances good enough? When does it make sense to call out for tighter tolerances? Do you need a better understanding of fits, datums, or GD&T? Learn about these topics and more in Xometry's new e-book. Download Now
When designing a metal component, engineers have to consider how susceptible certain alloys are to corrosion in the final productâ€™s operating environment. In a recent study by NACE (National Association of Corrosion Engineers), it was estimated that the direct and indirect costs of corrosion in the United States is approximately 6.2% of the GDP. In 2016, that cost exceeded $1 trillion dollars for the first time. Download Now
With all of the hype around 3D printing, it can be easy to get lost in fascinating, intricate metal parts made with additive manufacturing. These parts, while impressive, are probably dissimilar from many of the parts you currently produce or use. So why invest in metal additive manufacturing? Download Now
Construction was at one time a highly regionalized business. Pragmatic and market forces made it more efficient for even a large, industrial general contractor to focus regionally. But inexorable trends are making it more important for major commercial, civil, engineering and industrial contractors to grow their global footprint.
