February Joint Meeting - Section and Geo-Institute
At this elevation, the ground is permanently frozen and is covered in snow during 10 months of the year. Storms roll in with little to no warning, and the oxygen levels are less than 14% (versus 21% at sea-level). There are no roads to top of the mountain, and all access is provided via helicopters.
CJA had to come up with innovative solutions to excavate over 2000 yards of rock, remove massive amount of snow, and tackle logistical issues of transporting drill rigs, equipment and material to top of the mountain. CJA was able to install over 40 heavy duty micro-piles and tiebacks - embedded into the frozen ground - that will support the future structures against over-turning, rotation and sliding off the mountain.
