This project consisted of 97 drilled shaft foundations 60 inches in diameter, between 90 and 120 feet in depth. Phase I of the project had to be constructed in between the two existing IH 10 bridges, leaving a working width of only eighty feet (80’). The scope of work also included an Osterberg cell load test for design verification. Due to the footing for the new bridge foundations (consisting of clusters of 12-60” diameter shafts) and the narrow working width between the bridges, A. H. Beck used long reach drill attachments they had fabricated to be able to reach across the footings and construct each one from only one side.
