IRONWOOD, Mich. (WLUC) -- The Copper Peak Ski Jump is making progress toward building the world's largest ski flying hill and the only one hill for summer ski jumping.
They got a $125,000 grant from the Michigan Department of Agriculture, and another $25,000 from River Valley Bank and private fundraising.
After nearly two months working with Coleman Engineering of Ironwood, Michigan, Barr Engineering of Duluth, Minnesota and Gundlach Champion from Iron Mountain, Michigan those involved said they were making great headway on the design and engineering of the Copper Peak Landing hill.
To match the International Ski Federation (FIS) certified landing hill profile, the Copper Peak landing needs to be lifted, especially in the lower part. As they lift the landing hill, they also need to address environmental conditions such as drainage and insure that the hill is structurally sound and capable of holding a huge surface of plastic tiles that the athletes land on.
Barr Engineering has come up with an innovative solution using “Rip Rap mattresses” as a foundation for the landing hill surface and to build it up to the correct profile. The Rip Rap (aggregate/rock) is encased in a steel mesh that looks something like a chain link fence. This is then anchored into the bedrock using Tecco steel anchor bars. This method allows them to build up the hill while addressing slope drainage and stabilization. The Rip Rap is composed of a free draining rock which in allows water to flow through it. On top of this foundation they will install a cast in place concrete slab on which the landing surface will be installed.
Over the next few months they will continue with the engineering and design to be ready for construction in the spring of 2018 and events in 2019.
