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. Page 1 of 8 UES Project No.: 0610.1400037 UES Report No.: 12679 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. TABLE 1: HAND AUGER RESULTS Location: DCP-1 Feet Below Grade DCP Value Soil Description 0.0 —1.0 10-10-9 Brown to gray, loose fine sand, trace shell and gravel (SP) 1.0 — 2.0 11-10-10 2.0 — 3.0 10-11-11 Light gray, loose fine sand (SP) 3.0-4.0 9-11-10 4.0 — 4.8 15+ an, medium -dense fine sand, with shell and cemented sand Groundwater found 4.8 feet below land surface.

Page 2 of 8 i� Samples of the auger cuttings were with the guidelines of ASTM D 2488, Soils (Visual -Manual Procedure). 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. s by several interrelated of the subsurface; (2) pressures beneath the techniques used by the 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. Page 7 of 8 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. Page 8 of 8 � 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 P ly, on Your AMMember Geotechnclal gineer top Additional Assistance Membership in ASFE/fhe Best People on Earth exposes geolechnical engineers to a wide array of risk management techniques that can be of genuine benefit for everyone involved with a construction project.

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.
