Apt. 302, 7845 East River Road Fridley, Minnesota 55432 Attn: Mr. Richard Fidele Re: 69-253 INSPECTION Buildings 3 and 4 Meadow Run Apartments 7845 East River Road Fridley, Minnesota Gentlemen: As requested, an inspection to evaluate natural and fill soils in Building 3 in accordance with FHA requirements for 79G projects was conducted at 9:30 A.M., Friday, October 8. The footing trench for the outside northwest wall of Building 3 had been dug. Forms were being placed. The exposed natural soil was a -dark brown fine loamy sand similar to the fine sand encountered in boring ST -7 of our report of September 15, 1969. It appeared firm and capable of supporting the anticipated loads. The rest of the building area was approximately level and about 6 inches above the bottom of exterior footing grade. The southeast half of the building area was sandy fill with a maximum depth of about 30 inches. Compaction other than that due to scrapers running over the area had not been performed. The wheels of the scrapers had compacted the sandy fill in the area of the outside southeast wall footing and this area will be tested on Monday, October 11, for adequate density. Natural soils located on the inside southeast wall footing line had not been cut down to footing grade at the time of the inspection. Some topsoils were still in place, but they appear to lie above bottom of footing grade and subcutting under the footing does not appear necessary at this time. This area, however, will be subsequently reinspected.

BORINGS • TESTS • INSPECTION • ANALYSIS • REPORTS • RECOMMENDATIONS 69-253 Five Sands, Inc. -2- 10/11/71 It is recommended that when a vibratory roller is brought to the site, the loose fill in the floor slab area of the southeast half of Building 3 be compacted. As the sandy fill is not thick, adequate compaction should be possible without removing any fill already in place. At the time of the inspection, a dragline was excavating organic soils in the north wing of Building 4. Soil borings ST -9 and ST -10 in our report of September 15, 1969, had not detected a stratum of organic soils extending to a depth of at least 10 feet at the east corner. Most of this material has reportedly been excavated, starting from the south corner and working northeast. The eastern third of the excavation was under water. The excavation of the organic soils was expected to be complete by Friday afternoon, October 8. The location of the building had been marked in the following manner. Two stakes were set on the initially proposed southeast line of the building. It was indicated by Allan (Field Supervisor of Imperial Developers, last name not obtained) that the building location had subsequently been moved 20 feet northwest. The stakes are therefore 20 feet southeast of the currently proposed southeast line of Building 4. Excavation of organic soils was done southeast of the line between the stakes, hence oversizing in the excavation on the southeast side of the building was more than adequate. The northeast line of the building was marked by 2 stakes offset 12 feet northeast. The top of the stake at the east corner was reportedly the approximate footing grade. Standing water level in the eastern third of the excavation was then approximately 6 feet below footing grade. The excavation was probed along the northeast side and found to extend to at least 7 feet below standing water level. As the proposed footings are 24 inches wide, the bottom of the excavation should then be oversized at least 14 feet. It is now oversized less than 7 feet. Also, a form board thrust to the bottom brought up chunks of muck with shells. The insufficient oversizing and unexcavated muck were brought to the attention of Allan in the field. Spoil piles along the northeast side of the excavation would hinder further work from outside the excavation, therefore Allan proposed that fill be placed in the excavation starting from the west and working east. This would aid in pushing loose soils at the bottom towards the east corner. When the fill reaches the east corner, the dragline could work on the fill and complete the necessary oversizing outside the northeast building line. SOIL ENG/NEER/NG SERV/CES, INC- W 6�-253 Five Sands, Inc. -3- 10/11/71 It is regrettable that additional borings were not taken to determine the depth of excavation and probe for "false bottom" conditions or soft cohesive soils along the northeast and southeast building lines. It is our opinion that after fill has been placed to above ground water level, S borings should be taken to explore for trapped organic soils and evaluate soils beneath the fill. If more than a few inches of organic soils exist below the fill, it will be necessary to remove portions of the fill and excavate the trapped organic soils. This would be very costly in terms of both time and money. Backfill placed below water should be clean sand and/or gravel with less than 10 percent passing the #200 sieve. It appeared that the fine sand at the site contained more than 10 percent passing a #200 sieve, therefore, off-site sand will be necessary.

The purpose of the inspections was to evaluate the adequacy of the soil conditions encountered in the building excavation, while the compaction tests were taken to indicate the density of the fill materials placed for support of the proposed structure. The results of a soil boring investigation conducted by us and reported to Dolan Engineering Company on September 15, 1969 was available to aid in our inspections. This report is subsequent to our previous inspection report of Building #3 dated October 11, 1971. Additional inspections subsequent to that report were conducted on October 12 and 19, 1971. Our previous inspection and additional inspection on October 12 in Building #3 indicated adequate natural soils of fine sand. A limited amount of fill was placed at the south end. Density tests #1 thru 3 were taken in this area and indicated adequate compaction.

BORINGS • TESTS • INSPECTION • ANALYSIS • REPORTS • RECOMMENDATIONS �G'�s 69-2S3 Five Sands, Inc. -2- 10/21/71 The excavation for Building #4 was approximately 195 by 22S feet in plan. The excavation sloped uniformly from 6 feet to 11 feet from north to south. A 100 by 100 -foot area in the southeast corner had ponded a limited amount of ground water. A ditch was excavated to the adjacent creek on the south to aid in draining the water. A clean medium sand from McCrossan's Pit was approved for fill below water. During the period of October 15 to 19, 1971, 11 soil compaction tests were taken in Building #4. The tests were taken in accordance with ASTM D1SS6 (sand -cone method). Representative samples of each different type of fill material were returned to the laboratory for determination of maximum density and optimum moisture content in accordance with ASTM D1SS7-70 (modified Proctor). All test areas meet the specified minimum compaction of 90 percent of modified Proctor density. Based on the previous soil borings, our inspections of the excavations, and the compaction tests, it is our opinion that the areas tested and inspected to date will adequately support the anticipated building loads without detrimental settlement and with a factor of safety of three with respect to an actual shear failure.

The borings were generally located along the proposed exterior walls as marked by stakes set in the field. The elevation of the fill varied, but was approximately 6 feet below the proposed footing elevation. Accurate elevations of the surface were not considered important for the purpose of these borings, and hence were not determined. The borings were taken on the morning of October 22, 1971, by a truck -mounted power auger. The soils classifications and strata depths were inferred from the disturbed samples brought to the surface by the auger. Classifications were made by visual observation in the field in accordance with the U.S. Bureau of Chemistry and Soils Classification System. A chart of that classification system is attached.

The borings encountered only sand fill or underlying natural sand with the exception of sandy clay loam encountered at the 17 -foot depth in boring B-2. No trapped organic or cohesive soils were encountered in the borings. Hence, the borings indicate that these unsuitable soils were removed. Of necessity, the area of the borings in relation to the area of the site, and the depth of the borings, are limited.

The purpose of the inspection was to evaluate the adequacy of the soil conditions encountered in the building excavation, while compaction tests were taken to indicate the density of the fill materials placed for support of the proposed structure. Prior to our inspection, this firm has conducted a'series of soil boring investigations on this lot. The most recent investigation, the results of which were reported to you on January 24, 1973, was performed in the area of Building #5. The results of that investigation were available to aid in our inspection. The inspection was performed on May 1, 1973. At the time of the inspection, topsoils had been stripped in the northern portion of the building and in the western wing of the building. Several shallow hand probings were put down in these two areas. These BORINGS • TESTS • INSPECTION • ANALYSIS • REPORTS • RECOMMENDATIONS Five Sands, Inc. -2- 6/18/73 probings encountered brown fine to medium sand, fine sand and loamy sand. It is our opinion that the topsoils were properly stripped and that the granular soils encountered are capable of supporting a design bearing pressure of 2000 pounds per square foot (psf). It appeared that approximately 1 foot of topsoil had been stripped in these portions of the building. In the southern wing of the proposed building, the excavation extended to the 6 -foot depth or an approximate elevation of 845. In the southwestern corner of this wing, approximately one foot of water was present in the bottom of the excavation. Several shallow hand probings were put down around this pool of water. These probings encountered fine to medium sand. Due to the amount and depth of the water, no hand probings were put down in a 20 -foot square area in the southwest corner of the building. Boring ST -28, taken in this area, encountered fibrous peat to the 9 -foot depth as opposed to the 6 -foot excavation depth. Therefore, we could not ascertain whether all deleterious materials were excavated in this small section of the building. It was indicated to us by Mr. Fudali that this area of the building had been properly excavated although no equipment was present on the site to dig a test pit in this area. It is our opinion that the remainder of the building, excluding this 20 -foot square area in the southwest corner of the south wing of Building#5, was properly excavated and that adequate bearing soils were encountered throughout the excavation. Seven compaction tests were taken on the fill placed and compacted to bring the bottom of the excavation up to the proposed footing grade. Compaction test results are attached. All seven compaction tests met the specified minimum compaction of 900 of modified Proctor density (ASTM D1557-70).
