Minneapolis, Minnesota 55422 Attn: Mr. Robert Pierce (1) Village of Brooklyn Center LABORATORY No. 9-2633 Inspection Department INTRODUCTION This report conerns our recent soil inspection performed in certain floor slab areas at the referenced project. This work was conducted in accordance with a verbal authorization from Mr. Fink of William Kranz, Inc. The results of a preliminary soil investigation conducted at this site by Soil Exploration Company and reported to The Cerny Associates, Inc. on June 20, 1969, were.available for our use during the inspection. This report.indicated that the generalized soil profile consisted of about 2' of topsoil overlying sand, which was in turn underlain by sandy clays. The purpose of our inspection was to determine if the exposed soils would provide adequate support for the proposed slab -on -grade. INSPECTION On April 9, 1970, a visual inspection was performed of the soils in the garage area of the northern portion of the building. Several shallow hand auger borings were put down to aid in evaluating local subsurface soil conditions. Throughout the central portion of the area, the soil profile consisted of 2 to 3' of black to dark grayish brown silty sand underlain by brown medium to fine grained sand, all visually estimated as medium dense. However, very loose sand fill extending from grade to the depth of our hand auger borings (4') was encountered along the walls of the building. REMARKS Based on our visual inspection, hand auger borings and the preliminary soil investigation, it is our opinion that the soils encountered are adequate for support of the floor slab, with the exception of the very loose sand fill. The loose sands along the walls should be thoroughly compacted with a heavy vibratory roller to a minimum density of 95% of the maximum density as determined by the Standard Proctor Method, ASTM:D698-66T. We further recommend that several field density tests be performed in order to determine if adequate compaction of the sand fill is obtained. TWIN CITY TESTING AND ENGINEERING LABORATORY, INC.

EUE Secretary •Treasurer April 24, 1970 Re: Proposed Municipal Services Building Brooklyn Center, Minnesota On April 15, 1970, we made a visual inspection of the soil in the floor slab area at the above referenced project. It was our understanding that the purpose of the inspection was to determine if a 6" sand cushion had been, placed in this area. The soil exposed in the area was a silty sand, as explained in our letter dated April 20, 1970. On April 23, 1970, we received a call from Mr. Merila concerning these soils. He stated that there would be some difficulty in removing the top 6" of soil from this area and wanted an opinion as to the possibility of placing the floor slab directly on the silty sand. As per our telephone conversation, we explained that the reason the sand cushion is placed below a floor slab is to provide a free draining area in case of underlying frost susceptible soils and/or a high water table. We understand that the building will be completely enclosed and heated at,all times. Furthermore, the water table at the time of the original soil borings was about 10' below floor elevation. In light of this information, it is our opinion that the floor slab could be placed directly on the exposed soil and perform satisfactorily. As indicated in our original inspection report dated October 23, 1969, two tests in the top l' of fill failed to meet the recommended compaction. One.test was taken 35' west and 40' south of the northeast corner, and the other was taken 110' east and'50' south of the northwest corner. We recommend that these areas be recompacted and tested prior to pouring the floor slab. Zen" race Hassinger Geologist-InspectorL� J BH/NEH/AMC Norman E.-Henning, P.E.
