AESI provided a variety of engineering and surveying services for the Trail Creek Ranch improvements located between Bozeman and Livingston, Montana. The work included multiple new structures, renovation of several existing structures, and miles of new roadway in a mountainous environment. The improvements involved conducting geotechnical test pits, soil sampling, soils analysis, and slope stability analyses to provide recommendations for site development and construction. The new developments required multiple on-site wastewater treatment facilities which were designed and permitted by AESI. Surveying at the site involved pre-development conventional topographic survey, drone aerial survey and 3D modeling, and construction staking for excavation and road development. Stormwater improvements were also a large part of the project and involved permitting and permit administration for State construction stormwater discharge. Multiple plan sets were created for the different project aspects.
