661" Avenue and 16«' Street Improvements EXHIBITA Universal Proposal No. 1910. 0209. 00008 rev Page 2 Field Services • Drill three (3 ) SPT borings , one ( 1 ) adjacent to each of the proposed signal mast locations , to a depth of 25 feet bls . • Install a temporary piezometer at each boring location and obtain stabilized groundwater level readings . • Stake boring locations , provide utilities clearance , and obtain groundwater level readings . All SPT borings will be drilled in accordance with ASTM D 1586 ( Standard Method for Penetration Test and Split- Barrel Sampling of Soils ) procedures . The SPT borings will be sampled continuously at 18 - inch intervals from ground surface to a depth of 10 feet bls and at 5 feet intervals thereafter. The SPT borings will be performed using an ATV mounted drilling rig and/or a truck mounted drill rig using either rotary mud techniques or continuous flight augers to termination depth . Each recovered soil sample will be visually classified in the field and a geologic log prepared for each soil boring . Groundwater depths and any unusual subsurface conditions will be recorded on the boring logs . Representative portions of the recovered soil samples from each boring location will be sealed and packaged for transportation to our laboratory for a more detailed analysis , as required . All soil samples will be classified in general accordance with ASTM, D 2487 ( Standard Classification of Soils for Engineering Purposes ( Unified Soil Classification System ) ) guidelines . Analysis and Engineering Report Universal will prepare a geotechnical engineering report for 'the signalization portion of the project , which will respond to the proposed property development . The report will be prepared under the direction of a professional geotechnical engineer registered in the State of Florida . The report will summarize the field and laboratory services performed and provide an engineering analysis of the site soil and groundwater conditions with special attention to potential subsurface conditions that may hinder development . The final report will include the following : • Methodology and results of the field exploration . • Review of available data such as USGS Topographic maps , soil surveys and potentiometric maps . • Results of the laboratory testing program • Estimates of the typical wet season groundwater level at the boring locations • Recommendations concerning soil parameters for soil strata encountered for the design of a foundation for the proposed structures . Notes will be made as to whether the soils meet FDOT standard foundation criteria .
