Gessner Engineering provided geotechnical and structural engineering as well as construction materials testing services for the one-story stone office building totaling approximately 4,042 square feet. For geotechnical engineering, subsurface conditions were evaluated by drilling one test bore hole to a depth of 15 feet below the existing ground surface within the limits of the proposed office building. Gessner Engineering’s primary foundation recommendation was to support the proposed structure with a slab and grade beam foundation system to provide the best protection from soil movement. Construction materials testing and inspection services included concrete tests, in-place nuclear density tests and a sieve analysis. All density tests were taken at six inch depths in accordance with ASTM D 698. As requested, Gessner Engineering personnel were on site to witness the proof rolling of the building pad subgrade for this project.
