Contractor informed its earlier today that they were backfilling with drain rock today over the footing drains. We
arrived onsite this afternoon. Contractor had placed drain rock over footing drains and enclosed with filter fabric. We
recommended that they place more rock behind the retaining wall, over the footing and part way up the wall currently
covered by MiraDrain. The contractor anticipates only 5 feet of total backfill behind the garage retaining wall.
Placement and Compaction of Structural Fill
At the time of our arrival, the contractor was backfilling the new staitwell wall and the garage slab area to achieve up
to approximately 3 feet of fill. Fill was being placed and spread in less than 1 foot thick lifts with the excavator and
being compacted with a jumping jack. Soils consisted of brown sand with some silt and appeared to be close to the
optimum moisture content. We informed the contractor that the plans listed compaction as one of the items to be
inspected. The soils were in a firm and unyielding condition, based observations made visually and with a''/z inch
diameter, steel soil probe. The current fill Iayer could be probed with some effort under full body weight to the
previously compacted layer. The contractor was only making one pass with the jumping jack so we recommended that
they start making two passes. They planned to remove the partially placed loose lift, recompact a second time and
then continue. I informed the contractor that we would collect a sample of the soil and come back another day to test
compaction at the subgrade elevation. We tentatively scheduled for Wednesday (in 2 days).

As recommended, the contractor placed more rock behind the garage retaining wall.
While onsite, he ran water from a garden hose into the existing slab drain outside the existing basement door on the
south side of the house. He said that he had already tested it for 45 minutes earlier in the week and never saw signs of
it back flowing. The water was run for 20 minutes this afternoon, but its destination could not be determined. The
small volume of water already flowing in the existing street catch basin near the southwest property comer did not
appear to increase.
We understand that the existing drain located outside the southern basement door will be within the crawlspace for the
new construction. The contractor said that he planned to build a short concrete wall to confine the quarry rock
exposed under the new footing, which was above and near the existing south basement door. The short wall would also
help block potential seepages from the quarry rock. We suggested that he allow for a small drainage connection
between the quarry rock and the existing drain outside the southern basement door.
Placement and Compaction of Structural Fill- South Garage
The compacted soils for the southern garage slab and stairwell wall were at subgrade elevation and in a fine and
unyielding condition. Three density tests were conducted with a nuclear, moisture -density gauge with compaction
results ranging between 91 and 92 percent. The test locations are shown on page 2.
