If difficult access conditions (such <br /> as crossing wetlands or creeks)are encountered to access boring locations, additional fees will apply. <br /> • Work can be performed during standard work hours (8am to 5pm) Monday through Friday. <br /> • We assume the client will coordinate site access through any locked gates. <br /> • We assume that there will be no private underground utilities in the vicinity of the borings or that the <br /> client will coordinate location of any private underground utilities prior to drilling operations. <br /> • We assume that no more than 10 feet of cut/fill will be needed to mass grade the site. If cut depths <br /> exceed 10 feet in the building pad, additional fee may be needed to reach boring depths required for <br /> proper analysis. <br /> • We assume building loads and subsurface conditions are such that the proposed structure can be <br /> supported on shallow foundations. If loads are higher than those assumed or subsurface conditions <br /> are such that a deep foundation system is needed, additional fee may be needed for deeper borings <br /> to support the design. <br /> Field Exploration <br /> The field exploration will consist of the following: <br /> • A geotechnical professional will perform a site reconnaissance and locate exploration locations using <br /> GPS equipment. <br /> • Contact NC 811 to mark existing public underground utilities near boring locations. <br /> • Perform Twenty Standard Penetration Test (SPT) borings in accordance with ASTM D1586 to depths <br /> ranging from approximately 10 to 50 feet. Eleven (11) borings will be performed in the proposed <br /> building area to depths ranging from approximately 20 to 50 feet. Eight (8) borings will be performed <br /> in the proposed pavement areas to depths ranging from approximately 10 to 15 feet. Two (2) borings <br /> will be performed in the proposed BMP area to depths ranging from approximately 10 to 20 feet. Boring <br /> depths are referenced to the existing ground surface. Total drilling footage is expected to be up to <br /> approximately 450 linear feet. Borings will be performed to indicated depths, or auger refusal, <br /> whichever occurs first. <br /> • Within borings, split-spoon samples will be collected in conjunction with SPT testing. Split-spoon <br /> samples will be collected at 2-foot depth intervals in the top 10 feet and at 5-foot intervals thereafter. <br /> Upon completion of borings, borehole water levels will be recorded, and the boreholes will be backfilled <br /> with drill cuttings up to the original ground surface. Soil samples will be returned to our office for visual <br /> classification and laboratory testing. All excess spoils will be disposed of on site. <br /> • Bulk soils samples will be collected from the borings and returned to our laboratory for testing. <br /> Laboratory Testing <br /> We will perform laboratory testing on representative soil samples for the purpose of classifying the soils and <br /> estimating geotechnical engineering properties. We plan to perform Atterberg limits, grain size analyses, <br /> natural moisture contents, Standard Proctor, and California Bearing Ratio (CBR) testing. <br /> CIVIL ENGINEERING I ENVIRONMENTAL I SURVEYING I GIS I LANDSCAPE ARCHITECTURE I CONSTRUCTION SERVICES <br /> 6of22 <br />
