The drilled shaft foundations for the kcICON bridge over the Missouri River have been completed according to Dan Brown and Associates, LLC, the geotechnical engineers on the job. The 1700-ft long bridge conveys the I-29/35 over the River with the central spans being cable-stayed and supported by a single pylon in the river. The foundations for the central pylon consist of 8 10.5-ft diameter shafts socketed into bedrock. The land-based bents are supported on 6.5 to 8-ft diameter shafts and the abutments are on driven piles. Some of the drilled shafts were post-grouted as well. The project is scheduled for completion in the summer of 2011. Find much more about the project at the DBA website. (Photo by Dan Brown and Associates)
A New Mexico mountain resort recently unveiled their new fitness complex which featured a large indoor swimming pool and 32 person spa. Built on the side of a mountain, on side of the spa structure sits on top of approximately 12.0’ of fill material. When the spa and portions of the deck began to show telltale signs of settlement, the spa was drained and taken out of service, and an investigation was conducted. This investigation revealed a large plumbing leak which had occurred under the pool/spa deck, causing compaction and consolidation of the supporting fill materials. The general contractor on the job broke out a section of the pool deck to make the plumbing repair, and then turned to URETEK ICR for the remediation of the settlement issues.
Management was pleased that the process meant no disruption for their guests. URETEK’s solution was less than 20% of the cost of replacement of the structure.
