Visual observation techniques were employed to assure compliance with project drawings/specifications, applicable codes, and materials submittals. The following observations were made on site today:

• Work continued on Wall 1 until. The location of the wall is along the western most part of lot 9 (begin STA 0+00.00 , end STA 0+94.50)
  • Onsite material (Red Silty SAND) was used to build up the area beside the wall. (Moisture was at 21%) The area was compacted using a remote control sheep’s foot roller and a skid loader. The area was manually probed and within plan specifications.
• Digging continued on the sewerline (along Cannon Walk) using 2 full size CAT excavator from an area directly in front of lot 14 headed south toward the end of the cul-de-sac.
  • Compaction was performed (Cat Excavator with a sheep’s foot attachment) with onsite backfill material. (Red/Brwn Silty Clay, Located in front of lot 14) The fill material was at 19% moisture.
  • 9 lifts were placed in this area today. The undersigned observed the soil being placed in approximately 20 inch lifts and compacted with a CAT Excavator with a padfoot roller attachment.
  • The density test report for this day list the test result for the work performed on this day.
  • Based on the density test results, visual observation of the material placed and random probing of the placed lifts, the fill placed was found to be acceptable
• Grading continued on lots 10 – 16 using a full size CAT excavator, bulldozer, and dump truck.
• Grading continued and completed on lots 17 – 19
  • Lot 19 was cut to grade, and compacted (all compaction was performed with a full size sheep’s foot roller.) DCP tests were performed (see DCP test results) at two locations (East and West.) The compaction was found to be within plan specifications.
  • Lot 18 was cut to grade, compacted and DCP tests performed. (See DCP test results)
  • Lot 17 was filled to grade, Fill material was onsite (Red Silty Clay) two lifts were placed, compacted and DCP tests were performed.
  • The DCP Test results for this day list the test results for the work performed this day.
  • Based on the DCP test results, visual observation of the material placed and random probing of the placed lifts, the fill placed was found to be acceptable.
