Observations/Finding

The above-mentioned AS Engineering and Consulting (ASEC) representative, visited the Naturewalk at 7 Hills Amenities site to conduct quality control inspection and testing services. Visual observation techniques were employed to ensure compliance with project drawing/specifications, applicable codes, and materials submittals.  The following observations were made on-site:

• Rock Volume Determination for the blast was performed on this date: Rock volume was determined
  based on the attached drill logs. Drilling was performed on the days leading to today and depths to
  top of rock and termination was recorded.
• Drilled 176 blasting holes and completed 99 blasting locations.
• The total quantity of mass rock shot on this day was calculated to be 2,742.2 cubic yards.

• Larger boulders more than 2′ on all sides are break into small pieces with Deere breaker 350G lc.
•  Compaction testing was performed four times using a Troxler nuclear density gauge (30942), along with general probing using a 3/8″ diameter probe rod. few observations and necessary changes are suggested to foremen (Francisco).
