AESI worked with Centre Sky Architecture, Moonlight Basin, and the project team to design civil engineering services for a new dining facility. The project was located on the Moonlight side of the Big Sky Ski Resort on an undeveloped mountainside at approximate elevation 7700 feet, between the “Trembler” and “Horseshoe” ski runs. Civil engineering included design and grading for the parking lot, access road, entry points, patios, landscape berms, etc. The project also involved design and permitting for the public wastewater system for the facility. Detailed geotechnical work included over 15 excavated test pits and an evaluation of existing nearby boreholes. A thorough geologic study of the site was also conducted along with mapping of bedrock slopes and slope stability analyses. The geotechnical slope stability analyses worked closely with the civil grading aspects of the project to create a stable and safe configuration. A site-specific ground topographic survey and a drone aerial survey were conducted to supplement existing LiDAR survey data for the area.
