RE: _ Subsoil Investigation
Proposed Residence.
1308 Nettles Blvd:
Jensen Beach, FL34957
Dear Sirs:
Pursuant to your request; Federal Engineering &;Testing, Inc: has completed: a subsoil investigation on 12/1.6/201.5 at the .
above referenced 'site,: The purpose of •our investigation was to, verify _ subsoil• conditions relative to' foundation
preparation and design.
At otaYof two- (2) $PT borings were performed according to, AST -M D-1586-, one. (1) .drilled; down: to.'a depth of thirty .feet
(30) and'one:(.1) drille&down.to a depth of fifteen feet'(15) below the'existing ground surface. (See attached: field, sketch
for- locations): The following; is ageneral descriptionpf soil stratas for the-subje'ct.sitd:
Groundwater table elevation was measured munediaiely at the. completion of .each. boring and was found at an' average: .
depth of two. (2) feet below existing ground surface. Fluctuation in'water level should be anticipated due to seasonal
variations .and ran off .as well as varying ground;elevation, contraction dewatering and.pumping activities. in the'area.
Site contractor must familiarize himself with site conditions. in the event groundwater controls and dewatering is needed.
Surface . flooding may result under 'hurricane conditions and should . be taken. into: consideration in the design, of the
project. The. contractor shall make sure that groundwater levels. on adjacent properties are not affected,by the contractors
dewatering.activities. Specialty groundwatercontractors shall be. consulted for all work below the groundwater level.
The boring log(s), attached present a detailed.description of the soils encountered at each location. The :soil stratification: .
shown on the boring log(s) .is based on the .examination of the.xecovered'.soil samples. and interpretation of the driller.'s
field log. It, indicates only Y. approxinidte boundaries between soil. types. The, actual transitions between adjacent- soil
types: may be gradual.

.Drilling & Sampling. Procedures
The soil borings were installed in.accordance with Standard Penetration Tests procedures as set. forth in ASTM D-1586.
Representative samples were collected utilizing spilt -barrel techniques in accordance with the procedures'set forth in -
"Penetration Tests and .Spilt -Barrel Sampling, of Soil in; ASTM. D=1586. The ,following field .tests,- measurements and
laboratory analysis were p'erformed/collected during the installation of each soil boring. .
Penetration Tests .
During the sampling 'procedures, Standard Penetration Tests. were performed at five (5) .foot intervals to obtain the
standard penetration value (N) of the subsurface soil. The standard penetration value (I) is identified as the number of
blows ofa' -140-pound. hammer falling ahirty .(30) inches; required. 4o advance the spilt -barrel sampler: one (1) foot into the .
subsurface -soil.' .The sampler was lower,irito the bottom. of the previously cleaned.drill:hole and .advanced by blows from
the .hammer.: The number of blows was recorded for. each of the; three :(3) successive :increments . of six(6) :inches.: .
penetration. Thee"N" value'is obtained by.ttdding the second and third incremental numbers:. .
Water Level Measurements
Water Level depths: were obtained during; the test boring operaiion's..In relatively' pervious coils, such as sandy: soils; the
indicated depths. are usually reliable groundwater levels... Seasonal variations,:tidal.conditions, temperature, .land -use and
recent rainfall, conditions may -influence the depthsto groundwater levels.. _
Soil' Properties / Classification
All samples collected .were classified in .accordance with the. Unified Soil Classification. System criteria to. determined
soil material properties and compared with publishedliterature.of the USDA Soil Conservation Survey.
Ground Surface Elevations
Ground surface elevations have not .been. provided for the proposed boring locations. Therefore, all references to depth
of the various strata and materials encountered were from.existing grade at the time of the drilling operations:
Limitations of Liability
0.
Warranty .
,We warrant that the services performed by Federal Engineering and Testing,
Inc. (F.E.T.) are conducted in a manner consistent with the level of.skill and
care ordinarily exercised by members of the profession currently practicing
under similar conditions.. No other warranties, expressed or implied, are
made. While the services of.F.E.T..are an integral and, valuable part of the
design and construction process; we do not warrant, guarantee, or insure the
quality or compleieness'of services or satisfactory performance provided by
other members of the construction process, and/or the construction plans and'
specifications' which we. have not prepared,'northe ultimate performance of
building site materials. 'As • mutual protection to . clients, the .public and
ourselves, all reports are submitted:as the confidential propertyof clients, and
authorization for publication of: statements, conclusions or. extracts from or
regarding, our reports. is reserved pending our written. approval Reports are
not intended for'3rd party use.
Subsurface Exploration .
Subsurface exploration is normally accomplished by test borings. The soil .
boring log 'includes' sampling : information, description . of the, materials
recovered, approximate depths of boundaries. between soil and rock strata and
groundwater data, 'The log represents conditions specifically at the location
and time :the boring was made. The boundaries between different soil strata.
are indicated at specific depths;. however, these depths are in fact approximate
and dependent upon the frequency of. sampling. The transitions between soil
stratum• are often gradual. Water level readings •are: made at the time the.
boring Was. performed: and can. change with time; precipitation, canal levels, .
local well drawdown, and other factors. Regardless of the •thoroughness of a
Geotechnical exploration there'is always a possibility that conditions may be
different from those of the.test locations; therefore RE.T. does not guarantee
Any subsoil condition suriounding.the'.bore test holes. For a more accurate
portrayal of subsurface conditions, the •site contractor should perform.tests
pits. If different conditions, are encountered, F.E.T. shall be; notified to review
thg findings and. make any, recommendations as needed.
Laboratory'and Field Tests
Tests are performed in accordance, with specific ASTM Standards unless
otherwise: indicated. All• criteria• included in a.given ASTM Standard are not.
always required- and performed. Each test report indicates: the -measurements-
and determinations actually made.
Ownership of Tests /.Reports
All test results and/or reports prepared by F.E.T. pursuant to this agreement
and/or Addendum(s) thereto, ,shall remain the property'of F.E.T. until all
monies due and owing to. F.E.T, under this Agreement and/or Addendum(s)
thereto, are paid in full.
Analysis and Recommendations.
The.Geotechnical report is prepared primarily to aid in the design of site work
and structural' foundations.. Although the information in the report; is expected.
to be sufficient for these purposes,' it is not intended to determine the cost of
construction or' to stand alone as construction specifications.
Analysis and Recommendations cont.
In accepting this report the client understands that all data from the soil boring
is intended for foundation analysis only and is not to be. used for excavating,
backfilling or pricing estimates. In accepting this report the client understands
that all data from the soil boring is intended for foundation analysis only and
is not'to be used for excavating, backfilling or pricing estimates. The.site
contractor must familiarize themselves with the job site conditions: Soil
boring(s) on unmarked vacant' property or existing structure(s) to be
demolished is considered preliminary with further,boring(s) to be performed
after proposed building pad is staked. out. Report recommendations are based
primarily on data from test borings ;made at the locations shown on the test
boring reports. Soil variations may exist between borings and .may not
become evident •until construction. If variations are then noted, .F.E.T.. must
be contacted so that field conditions can be examined arid recommendations
revised if necessary. The;Geotechnical report states our understanding. as to
:the location, dimensions, and structural features. proposed of the,site:. Any
significant changes in the nature,: design, or location of the site improvements
must '.be communicated . to F.E.T. so that the Geotechnical analysis,
conclusions; and recommendation's can be, appropriately adjusted.
Construction Observations
Construction observation and testing is an important element of Geotechnical
services. The; Geotechnical Engineer's Field Representative (Field Rep.) is the
"owner's representative" observing the. work -of' the. contractor, performing
tests, and reporting data from such tests and observations. The Geotechnical
Engineer's Field Representative does not.direct the contractor's construction
means, methods, operations, or personnel. The Field Rep. does not interfere
with the relationship between the owner and the contractor, and except as an
observer, does not become a substitute owner. on'site. The Field. Rep. is only
collecting data for.our Engineer to review: The Field Rep. is responsible for
his/her safety, only, but has no responsibility, for the safety of other personnel .
and/or, the general'public at the., site., If the Field Rep. does not feel that the .
site is offering a safe environment for him/her; the Field Rep. will, stop his/her.
,'observation/ testing until he/she deems the site is safe: The Field:Rep, is an
important member; of a team, whose responsibility is to observe the test ,and
work being•done and report to the client whether that work is being carried
out in general conformance. with the plans and specifications.
Limitations of Report
Federal Engineering & Testing, Inc. shall have no liability, in contract, tort or
otherwise, for any ;inaccuracy, defect, or omission in interpreting :this report
and shall. not in any event have any liability for lost profits or any other
indirect,..special, incidental, consequential, exemplary or punitive damages. In
the event of future conflict between owners and contractors the following
applies: F.E.T.(s) legal and/or company representation and preparation for
representation fees will be billed on an .hourly rate; i.e. deposition, expert
Witness,. etc.. F.E.T. has no obligation to amend its conclusions or
recommendations after the date of this report. Any alterations or changes in
the. location of the project should be brought to our attention at the earliest
