1.0 INTRODUCTION
1.1 GENERAL
UES Project No.: 0610.1400037
UES Report No.: 12679
This report contains the results of a geotechnical exploration conducted for a proposed
addition at the existing single-family residence located at 22 Aqua Ra Drive, Jensen Beach,
St. Lucie County, Florida. This report includes the following sections:
• SCOPE OF SERVICES - Defines what services were completed
• RECOMMENDATIONS - Describes what we encourage you to do
• LIMITATIONS - Describes the restrictions inherent in this report
• SUMMARY - Reviews the material in this report
• APPENDICES - Presents support materials referenced in this report.
1.2 PROJECT DESCRIPTION
Our understanding of the proposed construction is based on conversations with you. The
project includes the construction of a CBS addition to the southeast building corner
approximately 14 x 30 feet in extent. We assume the planned construction will exert no
more than 4 kips per linear foot on continuous footings. The recommendations contained
herein are based upon the above considerations. If any of this information is incorrect or if
you anticipate any changes, UES should be notified immediately to review and possibly
amend the recommendations contained in this report.
2.0 SCOPE OF SERVICES
2.1 PURPOSE
The purposes of this geotechnical exploration were:
• to explore and evaluate the subsurface conditions at the construction site by
advancing Dynamic Cone Penetration (DCP) soil borings with special attention to
potential geotechnical considerations that may affect the proposed design,
construction, and serviceability of the proposed structure; and
• to provide geotechnical engineering recommendations for foundation design.
This report presents an evaluation of site conditions on the basis of traditional geotechnical
procedures for site characterization. The recovered samples were not examined, either
visually or analytically, for chemical composition or environmental hazards. UES would be
pleased to perform these services, if you desire.

2.2 FIELD EXPLORATION
On April 21, 2014 UES completed a hand -turned auger boring designated DCP-1 to a depth
of 4.8 feet below the ground surface in the planned foundation area. The approximate
location of the auger boring is shown in Appendix B: Boring Location Plan. The boring was
located on -site by UES personnel by measuring distances and estimating right angles
relative to existing site features and should be considered accurate only to the degree
implied by the methods used.
3.0 FINDINGS
3.1 SURFACE CONDITIONS
At the time of exploration, the site had been cleared of vegetation and landscaping. The
USDA -Natural Resource Conservation Service (Soil Conservation Service) soil survey of St.
Lucie County Florida maps the site within Arents, 0-5 percent slopes. These are somewhat
poorly drained nearly level to gently sloping sand soils, with depth to groundwater typically
18 to 36 inches below ground surface. Depth to weathered bedrock (limestone) is typically
greater than 80 inches.
3.2 SUBSURFACE CONDITIONS
Penetration tests were completed at one -foot intervals using a Model S-200 Dynamic Cone
Penetrometer (DCP) manufactured by Durham Geo Slope Indicator. The number of blows
required to drive the penetrometer a specified interval is referenced as an index of soil
shear strength. Table 1: Hand Auger Results presents the DCP values and soil
descriptions.

4.1 GENERAL
UES Project No.: 0610.1400037
UES Report No.: 12679
collected and visually classified in general accordance
Standard Practice for Description and Identification of
4.0 RECOMMENDATIONS
This section of the report includes detailed. recommendations for groundwater, building
foundations, site preparation, and construction related services. The following
recommendations are based upon the attached soil test data, our stated understanding of
the proposed construction, and experience with similar projects and subsurface conditions.
UES should be retained to observe the proposed construction, and provide updated
recommendations as required.
We note that since the applicability of geotechnical recommendations is very
dependent upon project characteristics, most specifically: improvement locations,
grade alterations, and actual structural loads applied, UES must review the
preliminary and final site and grading plans, and structural design loads to validate
all recommendations rendered herein. Without such review our recommendations
should not be relied upon for final design or construction of any site improvements.
4.2 GROUNDWATER CONSIDERATIONS
The groundwater table will fluctuate seasonally depending upon local rainfall. The rainy
season in South Florida is normally between May and October. Based upon the test boring
data, a reasonable estimate for the seasonal high groundwater table is approximately 3 feet
_ below existing grade.
Note that our estimate of seasonal high groundwater level is. based on limited data and
does not, provide any assurance that groundwater levels will not exceed the estimated level
during any given year in the future. If the rainfall intensity and duration or total rainfall
quantities exceed those normally anticipated, then groundwater levels will likely exceed the
seasonal high estimate.
The estimate of seasonal high groundwater level is made for the site at the present time.
Future development of adjoining or nearby properties and development on a regional scale
may affect the local seasonal high groundwater table. Universal makes no warranty on the
estimate of the seasonal high groundwater table.
UES recommends that all foundation and pavement designs incorporate assumption of the
seasonal high groundwater condition. We recommend that positive drainage be established
Page 3 of 8
UES Project No.: 0610.1400037
UES Report No.: 12679
and maintained on the site during construction. UES further recommends that permanent
measures be implemented to maintain positive drainage throughout the life of the project.
The performance of site improvements may be sensitive to their post - construction
relationship to site groundwater levels, seepage zones, or soil/rock characteristics
exposed at final grades. Since horizontal and vertical control of our site borings was
not provided, we do not recommend the use of our boring stratigraphy or
groundwater information for final grading and improvement design purposes. Such
use could result in potentially unacceptable performance of site improvements
and/or additional costs for unanticipated construction modifications. UES will not be
responsible or liable for the consequences of such use. UES recommends that use of
boring information for final design of all site improvements be predicated on proper
horizontal and vertical control of borings.
4.3 BUILDING FOUNDATIONS
4.3.1 SHALLOW FOUNDATIONS
We anticipate that the proposed structure can be supported on shallow foundations after the
site has been prepared as outlined in our site preparation recommendations found in
Section 4.4 of this report. Upon successful completion of the recommended site preparation
procedures, the anticipated structure will most likely be able to be supported on shallow
foundations sized to exert a maximum net soil bearing pressure of 2,500 pounds per square
foot (psf). Net bearing pressure is defined as the soil bearing pressure at the foundation
bearing level in excess of the natural overburden pressure at that level.
The estimate of maximum allowable bearing pressure is based on presumed wall
foundation load of 4 kips per linear foot. The estimate of allowable bearing pressure may
be refined based on more precise estimates of loads (provided by the structural engineer)
{ and proposed site grades. The foundations should be designed based on the maximum
load which could be imposed by all loading conditions.
Shallow foundations should be embedded at least 18 inches below lowest adjacent grade
(finished surrounding grade, for example). Further, maintain minimum foundation widths of
16 inches for strip footing, respectively, even though the maximum allowable soil bearing
pressure may not be developed in all cases. We estimate the foundations will have a
minimum. factor of safety of two against bearing capacity failure.
Post -construction settlements of the structure will be influenced
factors, including: (1) strength and compressibility characteristic
footing size, bearing level, applied loads, and resulting bearing
foundations; and (3) site preparation and earthwork construction
contractor.

Page 4 of 8
u
UES Project No.: 0610.1400037
UES Report No.: 12679
Our settlement estimates for the structure are based on the use of site
preparation/earthwork construction techniques as recommended above and in Section 4.4
of this report. Any deviation from these recommendations could result in an increase in the
estimated post -construction settlements of the structure.
Assuming all soils are properly prepared and using the recommended maximum bearing
pressure, maximum structural loads and the field data (which were correlated to
geotechnical strength and compressibility characteristics of the subsurface soils), we
estimate that total post construction settlements of the structure will be 1 inch or less.
Differential settlements result from differences in applied bearing pressures and variations
in the compressibility characteristics of the subsurface soils. If the recommended site
preparation and earthwork construction techniques outlined above and in Section 4.4 are
followed, differential settlements of'/ inch or less should be anticipated.
4.3.2 STANDARD FLOOR SLAB
For floor slabs, we recommend using a standard concrete slab -on -grade, reinforced with
welded wire mesh or macro -synthetic fibers to control cracking. Normal weight concrete
having a 28-day compressive strength (fc) of at least 3,0.00 pounds per square inch (psi)
should be used. A modulus of subgrade reaction of 150 pounds per cubic inch (pci) can be
used for design, assuming the slab is supported on compacted structural fill or compacted
existing subgrade soils. Further, the floor slab must be isolated from the building columns
foundations.
4.3.3 FLOOR SLAB MOISTURE CONTROL
The Florida Building Code requires the use of a vapor barrier beneath the floor slab to
control moisture. It is recommended that a minimum 6-mil, rolled plastic (Visqueen) vapor
barrier be used between the bottom of the floor slab and the top of the subgrade. This will
help to minimize floor dampness and moisture intrusion into the structure through the slab.
Care must be exercised during construction to prevent tearing or punching of the vapor
barrier prior to slab placement. Any tears must be repaired immediately.
4.4 SITE PREPARATION
We recommend normal, good practice site preparation procedures. These procedures
include: stripping the site of grass, deleterious material, proof -rolling, and proof -compacting
the subgrade, and filling to grade with engineered fill. A general outline of the anticipated
earthwork is as follows:
1. If required, perform remedial dewatering prior to any earthwork operations.
Page 5 of 8
UES Project No.: 0610.1400037
UES Report No.: 12679
2. Prior to construction, any existing underground utility lines within the construction
area should be located. Provisions should be made to relocate interfering utilities.
Note that if underground pipes are not properly removed or plugged, they may serve
as conduits for subsurface erosion which may lead to excessive settlement of
overlying structures.
3. Strip the proposed construction limits of all grass, construction debris, organic soils
and other deleterious materials within and 5-feet beyond the perimeter of the
proposed building.
4. The site should be graded to direct surface water runoff away from the construction
areas. Positive drainage must be maintained throughout the design life of the
project.
5. After clearing and stripping of the site is completed, the prepared subgrade soils
should be observed by a qualified geotechnical engineer or his representative to
locate any surficial deposits of organic soils, vegetation, excessive roots or debris.
Organic soils, vegetation, or deleterious material should be undercut until clean
natural soils are encountered, and the resulting excavations backfilled according to
the fill placement procedures provided later in this section.
6. In the areas to receive fill, the subgrade should be compacted using a smooth drum
vibratory roller in the static mode, having a minimum static, at -drum weight on the
order of 10 tons and a drum diameter on the order of 3 to 4 feet making a minimum
of eight overlapping passes with the second set of 4 passes perpendicular to the first
set of 4 passes. Typically, the material should exhibit moisture content within +/- 2
percent of the Modified Proctor optimum moisture content (ASTM D-1557) during the
compaction operations. Compaction should continue until densities of at least 95
percent of the Modified Proctor maximum dry density (ASTM .D-1557) have been
uniformly achieved within the upper 12 inches of the compacted natural soil surface.
Care should be exercised to avoid damaging any nearby structures while the
compaction operation is underway. Compaction should cease if deemed detrimental
to adjacent structures and the geotechnical engineer should be contacted
immediately. It is recommended that heavy vibratory equipment in the vibratory
mode remain a minimum of 50 feet from existing structures. Within this zone, use of
a track -mounted bulldozer, a heavy vibratory roller operating in the static mode, or a
smaller vibratory roller is recommended.
7. Place fill material, as required. The fill should consist of sand with less than 10
percent soil fines. Place fill in uniform 8-inch loose lifts and compact each lift to a
minimum density of at least 95 percent of the Modified Proctor maximum dry density
(ASTM D1557). The last 6 inches of fill beneath pavement areas should be
compacted to 98 percent of the Modified Proctor maximum dry density. Stabilize this
zone with shell or limerock as required to meet the subgrade recommendations
contained in the Pavements Section of this report.
Page 6 of 8
UES Project No.: 0610.1400037
UES Report No.: 12679
8. Complete in -situ density tests on the subgrade and each lift of fill at a frequency of
not less than one test per 2,500 square feet in the building area and one test per
10,000 square feet in paved areas.
9. In the building area, test compaction to a depth of 1 foot at the bottom of all column
footings. We recommend conduct one test for every 50 lineal feet of wall footing.
10. If difficult compaction conditions are encountered during the site work operations, the
compaction efforts should stop and the geotechnical engineer should be contacted.
The geotechnical engineer or his representative should observe proof -rolling of the
exposed subgrade to determine if additional compaction is warranted or if any
material needs to be over -excavated and replaced.
If site preparation work is performed during the rainy season (May through October), special
care should be taken to maintain positive drainage from the building pad and paved areas
to drains or ditches around the site. Unexpected wet _periods can also occur in Florida
during the "dry" season. Such events can raise water tables to levels above seasonal highs
without the associated high temperatures to evaporate ponded water. Therefore, the
contractor should practice wet weather means and methods for earthwork during the "dry"
season as well. Groundwater and surface water control, use of granular fill material and
aeration are typical means to accomplish wet weather grading. All fill materials that are
excavated from below the water table should be stockpiled for a sufficiently long period to
allow drainage.
4.5 CONSTRUCTION RELATED SERVICES
We recommend the owner retain UES to perform construction material testing and
observations on this project. Field tests and observations could include items such as
verification of foundation subgrade by cone penetration testing, monitoring of proof -rolling
operations, pile installation, and performing quality assurance tests on the placement of
compacted structural fill.
The geotechnical engineering design does not end with the advertisement of the
construction documents. The design is an on -going process throughout construction.
Because of our familiarity with the site conditions and the intent of the engineering design,
we are most qualified to address problems that might arise during construction in a timely
and cost-effective manner.

UES Project No.: 0610.1400037
UES Report No.: 12679
5.0 LIMITATIONS
Our field exploration did not find unsuitable or unexpected materials at the time of
occurrence. The test borings completed for this report were widely spaced and are not
considered sufficient for reliably detecting the presence of isolated, anomalous surface or
subsurface conditions, or reliably estimating unsuitable or suitable material quantities.
Accordingly, UES does not recommend relying on our boring information to negate the
presence of anomalous materials or for estimation of material quantities. Therefore, UES
will not be responsible for any extrapolation or use of our data by others beyond the
purpose(s) for which it is applicable or intended.
Geotechnical issues not addressed in this report may arise. Because of the natural
limitations inherent in working with the subsurface, it is not possible for a geotechnical
engineer to predict and address all possible problems. An (ASFE) publication, "Important
Information About Your Geotechnical Engineering Report" appears in Appendix C, and will
help explain the nature of geotechnical issues. -
Further, we present documents in Appendix C: Constraints and Restrictions, to bring to
your attention the potential concerns and the basic limitations of a typical geotechnical
report.
6.0 SUMMARY
In summary, we understand you propose to construct an addition to the existing single-
family residence located at 22 Aqua Ra Drive, Jensen Beach, Florida. Field tests have
been performed to provide geotechnical engineering recommendations for foundation
design and site preparation. The soils encountered generally consisted of loose to medium -
dense, gray to brown fine sand (SP) to the maximum explored depth of 5.5 feet (bis). The
borings found groundwater at a depth of 5 feet below ground surface. A reasonable
estimate for an average wet. seasonal high groundwater table is approximately 3 feet below
land surface (bls).
Estimates of allowable soil bearing values and estimates of settlement for the proposed
construction are covered in detail within the body of this report. If the subgrade soils are
prepared as recommended, the proposed building addition may be supported on a
conventional, shallow foundation system. UES recommends normal, good practice site
preparation procedures to prepare the subgrade to support the proposed improvements.
We note that since the applicability of geotechnical recommendations is very
dependent upon project characteristics, most specifically. improvement locations,
grade alterations, and actual structural loads applied, UES must review the
preliminary and final site and grading plans, and structural design loads to validate
all recommendations rendered herein. Without such review our recommendations
should not be relied upon for final design or construction of any site improvements.

� Geotechnical Engineering Report
Geotechnical Services Are Performed for
Specific Purposes, Persons, and.Projects
Geotechnical engineers structure their services to meet the specific needs of
their clients. A geolechnical engineering study conducted for a civil engi-
neer may not fulfill the needs of a construction contractor or even another
civil engineer. Because each geotechnical engineering study is unique, each
- geotechnical engineering report is unique, prepared solelyfor the client. No
one except you should rely on your geotechnical engineering report without
first conferring with the geatechnital engineer who prepared it. And no one
— not even you ---should apply the report for any purpose or project
except the one originally contemplated.
Read the Ftdl Report
Serious problems have occurred because those relying on a geotechnical
engineering report did not read it all. Do not rely on an executive summary.
Do not read selected elements only.
A Geotechnical Engineering Report is Based on
A Unique Set of Project-Spedfiie Factors
Geotechnical engineers consider a number of unique, project -specific fac-
tors when establishing the scope of a study. Typical factors include: the
client's goals, objectives, and risk management preferences; the general
nature of the structure involved, its size, and configuration; the location of
the structure on the site; and other planned or existing site improvements,
such as access roads, parking lots, and underground utilities. Unless the
geotechnical engineer who conducted the study specifically indicates oth-
erwise, do not rely on i geotechnical engineering report that was:
• not prepared for you,
- • not prepared for your project,
• not prepared for the specific site explored, or
• completed before important project changes were made.
elevation, configuration, location, orientation, or weight of the
proposed structure,
composition of the design team, or
project ownership.
As a general rule, always inform your geotechnical engineer of project
changes —even minor ones —and request an assessment of their impact.
Geotechnical engineers cannot accept responsibility or liability for problems
that occur because their reports do not consider developments of which
they were not informed.
Subsurface Conditions Can Change
A geotechnical engineering report is based on conditions that existed at
the time the study was performed. Do not rely on a geotechnical engineer-
ing report whose adequacy may have been affected by: the passage of
time; by man-made events, such as construction on or adjacent to the site;
or by natural- events, such as floods, earthquakes, or groundwater fluctua-
tions. Always contact"the geotechnical engineer before applying the report
to determine if it is still reliable. A minor amount of additional testing or
analysis could prevent major problems.
Most Geotechnical Findings Are Professional
Opinions
Site exploration identities subsurface conditions only at those points where
subsurface tests are conducted or samples are taken. Geotechnical engi-
neers review field and laboratory data and then apply their professional
judgment to render an opinion about subsurface conditions throughout the
site. Actual subsurface conditions may differ —sometimes significantly —
from -those indicated in your report. Retaining the geotechnical engineer
who developed your report to provide construction observation is the
most effective method of managing the risks associated with unanticipated
conditions.
Typical changes that can erode the reliability of an existing geotechnical
engineering report include those that affect A Report's Recommendations Are Not Final
• the function of the proposed structure, as when it's changed from a Do not overrely on the construction recommendations included in your
parking garage to an office building, or from a light industrial plant report. Those recommendations are not final, because geotechnical engi-
to a refrigerated warehouse, neers develop them principally from judgment and opinion. Geotechnical
engineers an finalize their recommendations only by observing actual
subsurface conditions revealed during construction. Me geolechnical
engineer who developed your report cannot assume responsibility or
liability for -die reports re_ commendafions if that engineer does not perform
construction observation.
A Geatechnical Engineering Report Is Subject to
Misinterpretation
Other design team members' misinterpretation of geotechnical engineering
reports has resulted in costly problems. Lower that risk by having your geo-
technical engineer confer with appropriate members of the design team after
submitting the report. Also retain your geotechnical engineer to review perfi-
nentetements of the design team's plans and specifications: Contractors can
also misinterpret'a geotechnical engineering report. Reduce that risk by
having your geotechnical engineer participate in prebid and preconstniction
conferences, and by providing construction observation.
Oa Not Redraw the Engineer's Logs
Geotechnical engineers prepare final boring and testing logs based upon
their interpretation of field logs and laboratory data. To prevent errors or
omissions, the logs included in a geotechnical engineering report should
never be redrawn for inclusion in architectural or other design drawings.
Only photographic or electronic reproduction is acceptable, butrecognize
that separating logs from the report can elevate risk.
'Give Contractors a Complete Report and
Guidance
Some owners and design professionals mistakenly believe they can make
contractors liable for unanticipated subsurface conditions by limiting what
they provide for bid preparation. To help prevent costly problems, give con-
tractors the complete geotechnical engineering report, but preface it with a
clearly written letter of transmittal. In that letter, advise contractors that the
report was not prepared for purposes of bid development and that the
report's accuracy is. limited; encourage them to confer with.the geotechnfcal
engineer who prepared the report (a modest fee may be required) and/or to
conduct additional study to obtain the specific types of information they
need or prefer. A prebid conference can also be valuable. 6e sure contrac-
tors have suftiient time to perform additional -study. Only then might you
be in a position to give contractors the best information available to you,
while requiring them to at least share some of the financial responsibilities
stemming from unanticipated conditions. .
Read Res{mnsibllity. Provisions Closely
Some clients, design professionals, and contractors do not recognize that
geotechnical engineering is far less exact than other engineering disci-
plines. This lack of understanding has created unrealistic expectations that
have led to disappointments, claims, and disputes. To help reduce the risk
of such outcomes, geolechnical engineers commonly include a variety of
explanatory provisions in their reports. Sometimes labeled "limitations"
many of these provisions indicate weere geotechnical engineers' responsi-
bilities begin and end, to help others recognize their own responsibilities
and risks. Read these provisions closely. Ask questions. Your geotechnicai
engineer should respond fully and frankly.
Geeenvironmental Concerns Are Not Covered
The equipment, techniques, and personnel used to perform a geoenviron-
mental study differ significantly from those used to perform.a geotechnical
study. For that reason, a geotechnical engineering report does not usually
relate anygeoenvironmental findings, conclusions, or recommendations;
e.g., about the likelihood of encountering underground storage tanks or
regulated contaminants. Unanticipated environmental problems have led
to numerous project tailures. If you have not yet obtained your own geoen-
vironmental information, ask your geotechnical consultant for risk man-
agement guidance. Do not rely on an environmental report prepared for
someone else.
Obtain Professional Assistance To Deal with Mold
Diverse strategies can be applied during building design, construction,
operation, and maintenance to prevent significant amounts of mold from
growing on indoor surfaces. To be effective, all such strategies should be
devised for the express purpose of mold prevention, integrated into a com-
prehensive plan, and executed with diligent oversight by a professional
mold prevention consultant. Because just a small amount of water or
moisture can lead to the development of severe mold infestations, a num-
ber of mold prevention strategies focus on keeping building surfaces dry.
While groundwater, water infiltration, and similar issues may have been
addressed as part of the geotechnical engineering study whose findings
are conveyed in -this report, the geotechnical engineer in charge of this
project is not a mold prevention consultant; none of the services per-
formed in connection with the geolechnical engineer's study
were designed or conducted for the purpose of mold preven-
tion- Proper implementation of ifre recommendations conveyed
in this report will not of itself Ire -sufficient to prevent mold from
growing in or on the structure involved

CONSTRAINTS AND RESTRICTIONS
WARRANTY
UES has prepared this report for our client for his exclusive use, in accordance with generally accepted
soil and foundation engineering practices, and makes no other warranty either expressed or implied as to
the professional advice provided in the report.
UNANTICIPATED SOIL CONDITIONS
The analysis and recommendations submitted in this report are based upon the data obtained from soil
borings performed at the location indicated on the Boring Location Plan. This report does not reflect any
variations which may occur in the borings.
The nature and extent of variations in the borings may not become known until excavation begins. If
variations appear, we may have to re-evaluate our recommendations after performing on -site
observations and noting the characteristics of any variations.
CHANGED CONDITIONS
We recommend that the specifications for the project require that the contractor immediately notify
Universal Engineering Sciences, as well as the owner, when subsurface conditions are encountered that
are different from those present in this report.
No claim by the contractor for any conditions differing from those anticipated in the plans, specifications,
and those found in this report, should be allowed unless the contractor notifies the owner and UES of
such changed conditions. Further, we recommend that all foundation work and site improvements be
observed by a representative of UES to monitor field conditions and changes, to verify design
assumptions and to evaluate and recommend any appropriate modifications to this report.
MISINTERPRETATION OF SOIL ENGINEERING REPORT
UES is responsible for the conclusions and opinions contained within this report based upon the data
relating only to the specific project and location discussed herein. If the conclusions or recommendations
based upon the data presented are made by others, those conclusions or recommendations are not the
responsibility of UES.
CHANGED STRUCTURE OR LOCATION
This report was prepared in order to aid in the evaluation of this project and to assist the architect or
engineer in the design of this project. If any changes in the design or location of the structure as outlined
in this report are planned, or if any structures are included or added that are not discussed in the report,
the conclusions and recommendations contained in this report shall not be considered valid unless the
changes are reviewed and the conclusions modified or approved by UES.

USE OF REPORT BY BIDDERS
Bidders who are examining the report prior to submission of a bid are cautioned that this report was
prepared as an aid to the designers of the project and it may affect actual construction operations.
Bidders are urged to make their own soil borings, test pits, test caissons or other investigations to
determine those conditions that may affect construction operations. UES cannot be responsible for any
interpretations made from this report with regard to its adequacy in reflecting subsurface conditions which
will affect construction operations.
STRATA CHANGES
Strata changes are indicated by a definite line in the soil description of this report. However, the actual
change in the ground may be more gradual. Where changes occur between soil samples, the location of
the change must necessarily be estimated using all available information and may not be shown at the
exact depth.
OBSERVATIONS DURING DRILLING
Attempts are made to detect and/or identify occurrences during drilling and sampling, such as: water
level, boulders, zones of lost circulation, relative ease or resistance to drilling progress, unusual sample
recovery, variation of driving resistance, obstructions, etc.; however, lack of mention does not preclude
their presence.
WATER LEVELS
Water level readings have been made in the drill holes during drilling and they indicate normally occurring
conditions. Water levels may not have been stabilized at the last reading. This data has been reviewed
and interpretations made in this report. However, it must be noted that fluctuations in the level of the
groundwater may occur due to variations in rainfall, temperature, tides, and other factors not evident at
the time measurements were made and reported. Since the probability of such variations is anticipated,
design drawings and specifications should accommodate such possibilities and construction planning
should be based upon such assumptions of variations.
LOCATION OF BURIED OBJECTS
All users of this report are cautioned that there was no requirement for UES to attempt to locate any man-
made buried objects during the course of this exploration and that no attempt was made by UES to locate
any such buried objects. UES cannot be responsible for any buried man-made objects which are
subsequently encountered during construction that are not discussed within the text of this report.
TIME
This report reflects the soil conditions at the time of investigation. If the report is not used in a reasonable
amount of time, significant changes to the site may occur and additional reviews may be required.
