DocuSign Envelope ID:7DEFBC40-ACE8-418F-A707-78004D4F60A4 <br /> Proposal for Subsurface Exploration Summit Proposal# G 16-0022 <br /> Soccer Center Expansion April 12,2016 <br /> Efland,North Carolina <br /> Within each boring, samples of subsurface soils will be taken at 2-'1/2 foot intervals above a depth of 10 <br /> feet. After 10 feet, we will sample every 5 feet to the full depth explored. An engineer or geologist from <br /> Summit will maintain a log of soil encountered and to obtain soil samples. Standard penetration tests will <br /> be conducted in conjunction with split-spoon sampling in general accordance with ASTM D 1586-99. All <br /> borings will be performed to the above indicated depths or auger refusal, whichever occurs first. Rock <br /> coring is not planned. Upon completion of the borings, measurements of groundwater levels will be taken <br /> and boreholes will be backfilled up to the original ground surface with auger cuttings. <br /> Task 003—Laboratory Testing <br /> Representative portions of soil samples will be returned to our laboratory for visual observation, <br /> classification, and laboratory testing. Atterberg limits and #200 sieve wash analysis tests will be <br /> conducted for soil classification and to evaluate physical and engineering characteristics of the subsurface <br /> soils. All laboratory testing will be performed in accordance with applicable ASTM standards. <br /> Task 004—Geotechnical Report <br /> Based on the results of the field exploration and laboratory testing, we will provide a written evaluation <br /> based on the site's suitability for the proposed development. This subsurface report will be signed and <br /> sealed by a professional engineer registered in the state of North Carolina, and will include the following <br /> information: <br /> • General description of the site, subsurface soils, and groundwater conditions; <br /> • Boring logs with soil strata descriptions, groundwater, and Standard Penetration Test <br /> N-values as a function of depth; <br /> • Depth and location of any rock or unsuitable materials encountered in borings; <br /> • Construction and earthwork recommendations, including subgrade preparation, <br /> grading and compaction requirements, effect of weather or equipment on soil during <br /> construction, groundwater control, analysis of expansive clays, or other deleterious <br /> conditions, etc. Recommendations on possible repair measures; <br /> • General recommendations for excavation of on-site materials; <br /> ® Suitability of on-site soils for reuse as structural fill; <br /> ® Cut and fill slope recommendations; <br /> ® Pavement recommendations for both flexible (asphalt) and rigid (concrete); and <br /> ® Results of laboratory testing. <br /> SCHEDULE <br /> We will schedule our field services upon receiving a written Authorization to Proceed and a signed <br /> Standard Contract for Professional Services. We expect that all fieldwork (clearing and drilling) will <br /> require 2 days to complete, provided there are no delays due to weather or unforeseen conditions. <br /> Completion of the visual classification, lab work, preparation of the boring logs,and the geotechnical report <br /> will be completed within 10 business days after the drilling has been completed. <br /> 2 <br />
