ATL <br />assumes that the permission to access the proposed boring locations along the project alignment will <br />be provided at ATL at no cost. <br />It is our understanding that HALFF Associates, Inc. assumed 15-feet to 30-feet deep borings will be <br />ideal proposed depths along the subdivision. Boring locations are shown in Figure 2: Proposed <br />Boring Location Plan. ATL assumed the twenty (20) borings inside Brookglen Subdivision require <br />pavement coring. Drilling and sampling will be done continuously to fifteen (15) feet and the deep <br />borings continuously to twenty feet (20) and 5 feet intervals after. Tabulation of soil borings and <br />depth are shown below. <br />Boring <br />Depth, ft. <br />Street Location <br />Coring required, Yes/No <br />B-1 <br />30 <br />Venture Ln <br />Yes <br />B-2 <br />25 <br />Venture Ln <br />Yes <br />B-3 <br />25 <br />Venture Ln <br />Yes <br />B-4 <br />25 <br />Venture Ln <br />Yes <br />B-5 <br />25 <br />Huntersfield Ln <br />Yes <br />B-6 <br />25 <br />Somerton Dr <br />Yes <br />B-7 <br />25 <br />Somerton Dr <br />Yes <br />B-8 <br />25 <br />Brookwood Dr <br />Yes <br />B-9 <br />25 <br />Brookwood Dr <br />Yes <br />B-10 <br />25 <br />Brookwood Dr <br />Yes <br />B-11 <br />15 <br />Brookwood Dr <br />Yes <br />B-12 <br />15 <br />Brookwood Dr <br />Yes <br />B-13 <br />15 <br />Gladwyne Ln <br />Yes <br />B-14 <br />15 <br />Brookwind Ln <br />Yes <br />B-15 <br />15 <br />Somerton Dr <br />Yes <br />B-16 <br />15 <br />Somerton Dr <br />Yes <br />B-17 <br />30 <br />Lazybrook Dr <br />Yes <br />B-18 <br />15 <br />Lazybrook Dr <br />Yes <br />B-19 <br />15 <br />Orchard Ln <br />Yes <br />B-20 <br />15 <br />Brookwood Dr <br />Yes <br />Soil Borings:2 @ 30' [60LF], 9 @ 25' [225 LF], 9 @ 15' [135 LF] TOTAL = 420 LF, Piezometer: 1 @ 25' [25 LF] <br />The field investigation will be performed in accordance with Standard Practice for Soil Investigation <br />and Sampling by Auger Borings [ASTM D 1452].
