Pine Glades is a luxury townhome development tucked into Snow King Mountain at Jackson Hole, Wyoming and has full ski-in, ski-out access. In order for the developer to gain approval for construction from the Town of Jackson, they had to create their own access to the property. Sounds easy, but the only solution was to create a 600’ vehicular tunnel that made three 90 degree turns as it climbed up a 15% slope as it crosses the face of Snow King Ski Resort two times. To add to the challenges, the top of the tunnel sits 45’ below the surface of the ski run. The developer is required to have the tunnel installed and backfilled before October 15th. It took all spring and summer to brainstorm, design and negotiate the details of the project. The actual building of the concrete components did not start until the first of September and had to be completed in record time.
In order to address the challenges, it took a team effort in engineering and construction. Idaho Falls secured the work and led the charge. We combined the efforts of four Oldcastle Manufacturing Plants to meet the schedule the developer faced.
- Idaho Falls Plant (ID) – 52 ea. 3-Sided Bridge Sections, 90 ea. Box Culverts, 25ea. Box Culvert Footings, 225 ea. Box Culvert Headwalls, 20 ea. Large Utility Vaults
- Nampa Plant (ID) – 36 ea. 3-Sided Bridge Sections
- Littleton Plant (CO) – 76ea. Post Tensioned Beams (Utilized when cover exceeded 12’)
- Ogden Plant (UT) – 135 ea. Box Culverts
- Total #’s of reinforcing steel – 820,000 #’s
- Total cubic yards of concrete – 4,404 CYD’s
The three sided split box culvert was a standard product, however the post tension beams we built were a specialty product that required some real work and ingenuity. The use of these special beams was made possible by incorporating the use of light weight foam fill for the first 12’ above the beams. The concrete beams rest on a cast-in-place concrete cap supported by micro-piles, soil nails and shot-crete installed by others. Our portion of the work on this project is just under $4,000,000 and it all had to be done in just a few weeks.
This project was a great success and a testament to the talented team we have at Oldcastle Precast. As a team we can all be proud of our contributions.
