THE FOLLOWING WAS NOTED: Associated Earth Sciences Inc. (AESI) was onsite at 7:30 Am and 1:30 PM to observe lot 6
building foundation subgrade and backfill.
Lot 6 Foundation Subgrade
We were on site this date in the AM to observe the remainder of
the subgrade overexcavation for Lot 6 building foundation south
end. The subgrade consisted of brown silty sand with some heavy
moisture in ceratin parts. The contractor excavated approximately
8-9 feet from final grade to reach foundation subgrade using a
large excavator. We assessed the subgrade using a ½” diamater
steel t-probe and confirmed the subgrade to be firm and unyieldng
probing no more than 2-3 inches suitable to support recycled
concrete structural fill (Photo 1). We understand that they will be
placing recycled concrete in the afternoon to bring the excavation
back up to foundation grade.
Lot 6 Backfill
We returned in the PM to observe the placement of the recycled
concrete backfill. The fill was being placed in lifts and bucket
tamped in place. The fill was in a firm and unyielding conditon and
suitable for the placement of the foundation.
