Visit Requested By: Tim (NEI) Met With (on site): NEI Crews
Purpose: Evaluate Subgrade for Lot 19
Outstanding Issues: FR25A (1 1/1 1) Plug Tract B Stormwater Pond Sinkhole
FR33 (12/4) Low Density Trench Backfill on SW Aubergine Terrace
While onsite for other earthwork activities, I observed that NEI crew members had prepared subgrade for lot 19.
Using a1/2" diameter foundation probe, I evaluated the subgrade approximately every 15 square feet. Subgrade
consisted of brown silt. Probe penetration ranged from 2 to 8 inches. Based on penetration resistance, the subgrade
appeared medium-stiff to stiff.
Based on observations and probing, the subgrade for lot 19 has been prepared in accordance with our geotechnical
recommendations.
