THE FOLLOWING WAS NOTED:
Lot 7 Building Foundation Excavation:
Prior to our arrival, the contractor excavated for Lot 7 building foundation subgrade (Fig 1). The contractor had excavated
approximately 8’ deep from existing grade. AESI was informed that the contractor would place and compacted approximately 5’ thick
of recycle concrete spalls to return to proposed subgrade. AESI observed and assessed the subgrade with a ½” diameter steel soil
probe. Exposed materials consisted of silty sands. In our opinion this area was firm, unyielding, and ready for backfill with the
following exception. While assessing the subgrade AESI noted a 4’ by 4’ area which was saturated and loose, AESI recommended
removing approxiametly 1.5’ deep of this material until firm and unyielding material is encountered and replacing with the recycled
concrete spalls. Mark Seek assured us that they will get this soft spot removed as well as remove and loose sediment which may have
accumlated in the bottom of the excavation.
AESI departed the site in the AM and will return upon request.
