“The owner wanted the building to feel ‘of the earth’, as if it was part of the landscape,” says OZ Architecture’s Becky Stone, explaining that the lodge’s rammed earth wall follows the contour of the land. Because construction of the wall took place during the winter, weather protection measures required fill dirt be kept above 40° F while heating and insulation systems protected the mixing station, 300-ft-long conveyors and installation area. Temperature sensors installed in the wall enclosure alerted the team when heater systems required attention—a situation that arose several times during overnight hours. In each instance, the problems were rectified to protect the wall and allow work to resume.

It was important for crews to minimize impacts to the natural environment and for the structures to blend in wherever possible with natural stone, wood and green roofs, Stone says. The lodge building’s skin is comprised of 12-ft customized panels fabricated in Michigan and erected on site; their design follows the rhythm of the surrounding aspen trees. Because many of the buildings are not air-conditioned, wood was delivered to the site one month before installation for conditioning to prevent cracking.

The final step to integrate the complex into its surroundings came as the team prepared to demobilize. Replanting trees and reseeding the valley made it appear as if the buildings rose naturally rather than as the result of a concerted construction effort.
