COVE POINT LNG EXPANSION
Kiewit Foundations Group reached out to KB early in the spring of 2015 for help on the Cove Point LNG Expansion project for which they were self-performing the installation of over 400 drilled shafts. After attempting for several months to install full length casing, they needed another option because they were getting far too much resistance, limiting their production. KB utilized their original design for the project using the Enhanced SlurryPro CDP system. The drilling conditions were extremely difficult due to the presence of liquefiable sand, fossilized seashells and marine clay. KB utilized several different additives to eliminate fluid loss and limit concrete overbreaks to less than 2% on each pile. KB assisted in the drilling and completion of the remainder of piles averaging 66 feet in depth.
