Deep Foundations

Project Partner: HK Contractors, Inc.

Challenge: Installing micropiles for new boardwalks on the edge of the Grand Canyon in Yellowstone National Park.

Overview: Condon-Johnson was contracted to install micropiles for the foundation support on three new boardwalks and also for the support of a failing retaining wall. The micropiles were located on the edge of the Grand Canyon which has an 800 foot drop off.

Results: Condon-Johnson was able to successfully overcome the very limited and technical access to install the micropiles. All personnel were tied off during the phasing of the work and the drill rig was winched down the slope to the edge of the cliff. The project was completed ahead of time and on budget.
