' GEOTEO{WGL ENGINEEPoNG STUOV E-12863 1 March 17,2007 � In no case should the stripped or grubbed materials be used as structural fill or mixed with material to be used as structural fill. The stripped materials may be "wasted" on site in non- structural landscaping area�, or they should be exported. ' Existing utility pipes to be abandoned should be plugged or removed so that they do not provide a conduit for water and cause soil saturation and instability problems. � Following the stripping operation, the ground surfact: where structural fill, foundations, slabs, or pavements are to be placed should be observed by a representative of ECI. Soil in loose 1 or soft areas, if recompacted and still yielding, sho�ld be overexcavated and replaced with a granular structural fill. The optional use of a geotextile fabric placed directly on the overexcavated surFace may also help to bridge unstable areas. ECI can provide Irecommendations for geotextiles, if necessary. Temporary Excavations IThe following information is provided solely as a service to our client. Under no circumstances should this information be interpreted to mean ti�at ECI is assuming ( responsibility for construction site safety or the contractor's activities; such responsibility is 1 not being implied and should not be inferred. I In no case should excavation slopes be greater than the limits specified in local, state (WISHA), and federal (OSHA) safety regulations. Based on the information obtained from our subsurface exploration, the loose soils encountered within the top 10 feet of the borings � wouid be classified as Type C by WIS:iA/OSHA. Temporary cuts greater than 4 feet in height in Type C soils should be sloped at an inclination of 1.5H:1V (Horizontal:Vertical). The medium dense to very dense soils underlying soils would by classified as Type A by ( WISHA/OSHA. Temporary cuts greater than 4 feet in height in Type A soils should be sloped at and inclination of 0.75H:1V. If seepage is encountered in the excavation, the soii type should be considered Type C and cut accordingly. , An ECI representative should observe temporary excavations to verify soil and groundwater 1 conditions and the soil type. If slopes of the above inclinations or flatter cannot be constructed, temporary shoring may be necessary. Shoring recommendations are provided in the "Shoring Recommendations" � section below. , Structural Fill Structural fill is defined as compacted fill placed under buildings, roadways, floor slabs, pavements, oiher load-bearing areas, or behind retaining walls. Structural fill should be placed in horizontal lifts not exceeding 12 inches in loose thickness and compacted to a minimum of 95 percent of its laboratory maximum dry density determined in accordance with ASTM Test Designation D1557 (Modified Proctor). The fill materials should be placed at or near their optimum moisture content, EART}i CONSUUING IMCQRPORATED Paae 5
