Working on a customized trestle in the middle of a stream, crews recently installed in Oahu, Hawaii, what officials say may be the deepest 10-ft-dia cast-in-drilled-hole pile (CIDH) in foundation history.
A design-build joint venture team of Shimmick/Traylor/Granite, working since 2017 on an $875-million contract to build 5.2 miles of elevated light rail, began installation in late May of a 357-ft-long pile down to 332 ft deep. It is one of 225 CIDH piles required for the project, slated for completion in 2021 as part of an overall 20-mile, $8-billion system.
