As requested, KSM Engineering & Testing has performed a subsurface investigation at the above
referenced site. The data gathered during the investigation, together with our geotechnical related
opinions, are included in this report.
Site Description:
At the time of drilling, the waterfront site was flat and had the footprint of the residence marked in the
field with stakes.
Site Investigation:
The site investigation program consisted of performing thirteen (13) Standard penetration test borings in
the proposed footprint of the structure. The borings were terminated at depths of 8 to 14 feet below
existing grade. These tests were performed in order to verify that the soil densification had been achieved
through grouting under pressure. The locations of the borings are indicated on the attached boring
Location Plan.
The SPT borings were completed in accordance with procedures described in ASTM D-1586. A standard
1.5 inch I.D., 2 inch O.D. split -spoon sampler is driven into the soil by successive blows of a 140 pound
hammer freely falling 30 inches. The number of blows required to drive the sampler 1 foot, after seating
6 in., is designated the Penetration Resistance, or "N" value. At regular intervals the sampler is extracted
from the ground and opened to allow visual examination and classification of the retained soil sample.
Also, the groundwater table was allowed to stabilize and the depth of the groundwater elevation recorded
from existing grade.
The records of the soils encountered, the penetration resistances and groundwater level are shown on
the attached logs.

Engineering Evaluation and Conclusions:
We performed borings on this site in order to verify that the site had been properly stabilized through
cement grouting under pressure, the results of these investigations are as follows:
September 21, 2019, we performed Borings SPT-1 through SPT-4, we did not find the site had been
densified as recommended in our report. There was still a loose layer between 5 and 7 feet below grade.
We informed the contractor that the soils had not achieved densification.
September 30, 2019, we performed Borings SPT-5 through SPT-11 and found the rear of the property had
been densified however we still found the loose layer in the front of the property. SPT 6, SPT 7 and SPT 8
showed densification, SPT 9 was done as a control boring at the request of the grout contractor. SPT 10
was a boring done using a different mixture of grout. SPT 5 and SPT 11 did not show densification. We
informed the pressure grout contractor of our findings and recommended further review by them. The
pressure grout contractor came onsite on October 4, 2019 to add additional pressure grout locations.
October 7, 2019, we performed Borings SPT-12 through SPT-13 and found the soils had been densified in
the locations tested.
Even though we have borings showing the soil has been densified, due to the variations in the soil profiles,
we are recommending top steel be placed in the foundation to allow the entire foundation to engage and
bridge any possible loose soils. The contractor shall install two #5 bars at the top of the footer with #3
stirrups at 6' o.c. The site should be prepared in accordance to our previous soils report, dated April 1,
2019.
Closure:
This report has been prepared in accordance with generally accepted soil and foundation engineering
practices based on the results of the test borings and the assumed loading conditions. No warranties,
either expressed or implied, are intended or made. This report does not reflect any variations which may
occur between the borings. If variations appear evident during the course of construction, it would be
necessary to re-evaluate the recommendations of this project. Environmental conditions, wetland
delineation, water quality, and municipal requirements are not a part of this report. We are pleased to be
of assistance to you on this phase of your project. When we may be of further service to you or should
you have any questions, please feel free to contact us.
