The F&R technician arrived on -site as requested by Mr. Keith Moretz of Moretz & Sipe to re-
evaluate the foundation subgrade at pier locations A-1,
Hand probing of the sidewalls of the excavations at an angle revealed firm soil conditions,
suggesting that the soft surface soils encountered on May 14, 2004 may have been a result of
over -excavation and replacing the soils without compaction -
Hand probing of the excavated footings listed above revealed firm soil conditions after the
subgrade was compacted with a hand tamper, as recommended.
The F&R technician performed six Dynamic Cone Penetrometer (DCP) tests, After discussing
the test results with Mr. Michael Sloan of F&R, Mr. Sloan indicated that based on the results of
the DCP testing and the In -place density test results, the foundations are suitable for support of
foundations designed for 2,000 pounds per square foot soil bearing capacity, Mr, Hymel was
informed of the test results and requested that the reports be foxed to his office as soon as
possible, so that he may place concrete tomorrow.
oo be ex«osed to rain Qrior to concrete placement,
F&R recommends that the subgrade be re-evaluated.

moajp&i��Itgd bx Mr. Steve H�,,mel of Moss -Marlow to rf A
a subgrade evaluation of the pier footings exca�ated around the building perimeter, Hand
probing revealed firm soils at some pier locations, and soft soil conditions at others. MT. Hymel
stated that the building inspector was concerned that the subgrade at some locations did not
meet 2,000 pounds per square foot (psf) bearing capacity as required.
F&R had previously conducted 'spot check' in -place density testing on the fill placed to develop
the small building pad. Ten Dynamic Cone Penetrometer (DCP) tests were conducted; one at
each pier location. The results indicated that 2,000 psf soil bearing capacity had been achieved
at only 4 of the 10 test locations, Mr. Hymel was notified of the test results on site, After
discussing the results with Mr, Michael Sloan of F&R, M. Sloan recommended that the subgrade
at the failing test locations be either compacted with a hand tamp, or over -excavated about 6
inches to achieve 2,000 psf bearing capacity, No action was taken to correct the low bearing
foundation subgrade on this date due to the late time of day
