PROJECTS

For this large warehouse structure, the geotechnical challenge is deep, soft, wet soils. My client, the general contractor, had to lift some very heavy concrete wall panels into place. The heaviest panel weighs 95 tons, and the crane used to lift them weighs 260 tons. My job was to make sure the crane did not sink into the ground when making the heavy lifts. I designed bearing pads under the crane tracks. These pads consist of 1 to 5 feet of crushed limestone, layers of geogrids, and layers of large wood timbers.
