GEOTECHNICAL ENGIN'eERING STUDY 1920 Grand c/o Stucheli Enterprises =-'�6S December 21, 2000 Page 6 During dry weather, most soils, which are compactible and non-organic, can be used as structural fill. dased on the results of our laboratory tests, the existing soils are generally � over the optimum moisture content and will need to be moisture conditioned prior to their use as structurai fil�. We anticipate some of the site soils wit! be usable for backfill provided they are stockpiled and covered until use. During dry weather, most non- �� organic compactible soil with a maximum particle size of six inches can be used. Fill for use during wet weather should consist of a fairly well graded granuta- material havin6 a maximum particle size of six inches and no more than 5 percent fines passing the No. 200 sieve based on the minus 3/4inch fraction. A contingency ir the ea~hwork budge: should be inciuded for this possibility. Excavations and Sbpes We anticipate the cut along Grard Avenue can be accomplished with temporary cuts provided an easement can be obtained for the City of Everett to remove the sidewalk. The side walk should be replaced as part af the project as the existing sidewalk is in poor ' condition. Temporary cuts on the north side of the site should start a minimum of five feet from the foundations of the adjacent residence. The following information is provided sulely as a service to our client. Under no circumstances should this information be inte�preted to mean that ECI is assuming responsibility for construction site safety or the contractor's activities; such responsibility is not being implied and should not be inferred. In no case should excavation slopes be greater than the limits specified in local, state, and Federal safety regulations. Based on the information obtained from our field ` exploration and taboratory testing, the existing fill would be classified as Type C by L OSHA. Temporary cuts greater than four feet in height in Type C soils should be sloped at an inclination of 1 .5H:1 V (Horizontal:Verticaq. The siit and clay native soil would be classified as Type A by OSHA. In Type A soils temporary cuts greater than four feet in � height can be steepened to 3/4H:1 V. If slopes of this inclination, or flatter, cannot be constructe�, temporary shoring may be necessary. Shoring recommendations are provided in the following section. r ; ` � Erth Con*+Itann, Ina /�1 � �� L
