The century-old Sisters of St. Joseph of Chambéry convent is being transformed into One Park, a 294-unit multi-family housing complex located on the 22-acre campus. The Sisters will continue to occupy apartments in one area, while the remainder will be renovated into studio, one-, two- and three-bedroom apartments. Langan provided multidisciplinary services to support the building foundation and site development of this complex project. We designed site, grading, and drainage improvements to maximize the usable area of the property and incorporate myriad amenity spaces. Geotechnically, the project was constrained by subsurface conditions and short- and long-term settlement criteria for constructing an addition adjacent to the structure. We helped develop foundation recommendations to meet the project settlement criteria and address constructability and settlement concerns.
