Re: Limited Subsurface Evaluation
The Reserve at Regents Center

Lexington, North Carolina
Excel Project Number 2016103
Dear Mr. Ratchford:
Excel Civil & Environmental Associates, PLLC (Excel) has performed a limited subsurface
evaluation of the above-referenced site in Lexington, North Carolina. As requested, Excel
personnel mobilized to the site on December 15, 2016 to evaluate the existing soil conditions in
regards to capable bearing capacities at various locations as requested by the client. Drilling
activities were conducted in order to determine the soil and bedrock conditions in the
proposed construction area and to evaluate pertinent physical properties of the soils
encountered
Fourteen (14) soil borings were completed and tested in approximately 2-foot depth intervals
beginning at grade level. The test locations were evaluated by utilizing a Dynamic Cone
Penetrometer (DCP). When testing, the technician records the number of strikes required to
drive the point through three increments of 1.75-inches and records the average number of
strikes in the second two increments as the penetration resistance at that depth. The
penetrometer reading is similar to the Standard Penetration Resistance "N-value" as defined by
ASTM D1586. When properly evaluated, the penetrometer test results provide an index for
estimating both soil strength and relative density.

General Soil Conditions
Borings B-1 thru B-3, B-6, B-7, B-9, B-10, B-12 and B-13 were completed to a total maximum
depth of ten fbgl. Borings B-4, B-5, B-8, B-11 and B-14 were completed to a total maximum
depth of seven fbgl. Field personnel visually examined the samples collected from the borings
to estimate the distribution of grain sizes, plasticity, organic content, moisture condition and
color. The observations for soil samples collected from select borings are summarized on the
attached Boring Logs included in Appendix A.
During the site visit, the property was observed to be an existing apartment complex with the
proposed apartment building locations to be open, grassy areas. The topography of the
property was generally sloping downward from northeast to southwest. Residual materials
were encountered beneath the subgrade for borings B-3 through B-12 consisting of clay, silty-
clay and silty-sand observed from grade to approximately ten fbgl. Organic materials were
encountered at borings B-1, B-2, B-13 and B-14. Soil borings B-1 and B-2 had an organic layer
from approximately five fbgl to the boring termination depth of ten fbgl. Soil borings B-13 and
B-14 had an organic layer from grade to a depth of approximately three fbgl. Results from DCP
testing indicated the soil bearing capacity of subsurface soils at all testing locations ranged, at
various depths, from 0 pounds per square foot (psf) to greater than 4,500 psf.
Groundwater was not encountered at the subject site during drilling activities to a depth of 10-
fbgl or the boring termination depth at any of the boring locations, meaning that the soils were
not observed to be considerably wet, soft or loose at a specific depth. However, it should be
realized that the water content of the near surface soils at the site could significantly change
between the time our report is submitted and construction is initiated at the site.
It should be noted that some of the material excavated from borings B-1, B-2 and B-6 through
B-13 on the property was classified as being either moist or saturated. This condition may be
due to recent precipitation and these areas should be monitored during construction activities
for any moisture-related problems related to excessive moisture in the soil. This can create a
situation in which water is absorbed into spaces between soil particles and the soil becomes
less dense, which reduces its ability to support a load.
For more detailed soil descriptions and stratifications at a particular boring location, the
respective boring log should be reviewed.
Laboratory Data
One Standard Proctor Compaction Test was conducted in the laboratory with the sample
collected from soil boring B-11. The Standard Proctor Compaction Test is used to determine
the maximum dry unit weight and optimum moisture content, which can be used for
specification of field compaction. The sample was classified as a yellow silty CLAY and had a
EXCEL CIVIL&ENVIRONMENTAL ASSOCIATES,PLLC

Limited Subsurface Evaluation January 11, 2017
The Reserve at Regents Center
Lexington, North Carolina Excel No. 2016103
maximum dry density of 84.7-pcf with an optimum moisture content of 31.2-% (see Appendix
A).
Limitations
The surface soils encountered at this site are of a type that will soften significantly if the soil
water content should be increased for any reason. Such increases in soil water content
normally cause difficulties in proper soil compaction. Sources of increased water content in the
surface soils could include, but are not limited to, rainwater, improper surface drainage during
earthwork or site grading, and broken or leaking utility lines. It should be realized that the
water content of the near surface soils at the site could significantly change between the time
our report is submitted and construction is initiated at the site. Unanticipated soil conditions at
a construction site are commonly encountered and cannot be fully predicted by soil samples,
test borings, or test pits. Such unexpected conditions frequently require that additional
expenditures be made by the owner to attain a properly designed and constructed project.
The analyses, conclusions, and/or recommendations contained in this report are based on site
conditions as they existed at the time of our field investigation, a limited number of soil borings,
and further on the assumption that the exploratory borings are representative of the sub-
surface conditions throughout the site, that is, that the sub-surface conditions everywhere are
not significantly difficult from those disclosed by the borings at the time they were completed.
If, during construction, different sub-surface conditions from those encountered in our borings
are observed, or appear to be present beneath excavations, we must be advised promptly so
that we can review these conditions and reconsider our recommendations where necessary. If
there is a lapse of time of more than one year between submission of this report and start of
the work at the site, if conditions have changed due either to natural causes or to construction
operations at or adjacent to the site, or if building locations, structural loads, or finish grades
are changed, we urge that we be promptly informed and retained to review our report to
determine the applicability of the conclusions and recommendations, considering the changed
conditions and/or time lapse.
Further, we request that our firm be retained to review those portions of the plans and
specifications for this particular project that pertain to earthwork and foundations as a means
to determine whether the plans and specifications are consistent with the recommendations
contained in this report. In addition, we are available to observe construction, particularly the
construction of foundations as recommended in this report, and such other field observations
as might be necessary.
This report has been prepared for the exclusive use of Southwood Realty Company for specific
application to sub-surface conditions associated with the property located at 100 Regents
Center Court, Lexington, North Carolina. The only warranty made by us in connection with the
services provided do reputable members of our profession practicing in the same or similar

conditions. No other warranty, expressed or implied, is made or intended.
