Box 66 Crystal Bay, MN 55323 Dear Mr. Gerhart: Re: Excavation Observation for the Proposed Fuel Tank Pad, Public Works Pazking Area, Orono Public Works Building, Orono, Minnesota As you authorized on December 1, 1992, we have completed excavation observations for the proposed fuel tank pad in the Public Works parking area of the Orono Public Works building in Orono, Minnesota. The purpose of our excavation observation was to assist in judging the suitability of the soils in the pad area for foundation support at that time. Background Information Braun Intertec has been involved with site preparation activities for the recent City Hall, Public Works Garage, Police Station and pazking lot construction. The bulk of that work was performed during the summer of 1992. Earthwork correction activities included site stripping and fill placement in the proposed fuel tank area locateti about 50 feet east of the new Public Works building. Mr. John Gerhart of the Citv of Orono indicated that above-ground fuel tanks were to be installed on a pad in the Public Works parking azea. The fuel tanks will rest on a 10-foot by 22-foot slab which is 6-inches thick. The total load on the slab will be about 61 kips. Locations and Elevations The locations observed in the field at the time of our work and referenced ia this report were from Plan PRD1.3 prepared by Boarman and Associates and dated February 26, 1992. In addition, Mr. Doug Rivard from Kraus-Anderson Construction Company showed us the proposed pad area.
