BIG SKY CONSTRUCTION UPDATE:
This June, over half a ton of explosives were used to precisely break down parts of solid rock in the peak, creating a workable area for drilling. To help create a sturdy foundation for the top terminal, a footing and large retaining wall support the East face, and 23 micropiles secure the terminal deep into the bedrock to counteract the pulling force of the Tram from below.”The micropiles help hold the foundation in place and minimizes the excavation needed. We are building this structure for the future – to last many decades up in some of Montana’s harshest weather conditions,” said Ty Jahn, project manager for Condon Johnson, the contractor building the top terminal.
Helicopter trips are happening frequently as more materials are being brought to the summit. This past week, materials, drills, and compressors were flown to the surface to begin micropile installation.
At the tower site, about 600 feet below the top terminal location, team members are creating a level surface to eventually move materials down to, where more drilling and blasting will happen.
