Remediation Contractor Permit No. SLC1402-0264 SDII Project No. 8058005D i " Dear Ms. Pryor: SDII Global Corporation (SDII) is pleased to present this report"summarizing the underpinning remediation performed at the Lyshon residence located at 2601 Gray Twig Lane in Fort Pierce, Florida. Figure 1 illustrates the project location. BACKGROUND INFORMATION SDII was retained to monitor and confirm that foundation repairs were made in substantial compliance with the recommendations made in our Foundation Stabilization Recommendations, dated October 31, 2013, SDII Project Number 8058005C. The purpose of the underpinning program was to stabilize the foundation of j the structure. SDII monitored the contractor's operations during the underpinning to verify compliance with the .intent of , SDII's recommendations. Although SDII monitored the contractor's operations, SDII did not have control over, charge of, or responsibility for the construction means, methods, techniques, sequences or procedures or for the safety precautions and programs performed in connection with the work, since these are solely the contractor's responsibilities. t Completion Report of UnderpinningRemeaiaron -- Marrh31,2014 Lyshon residence - Fort Pierce, Florida Claim No. 069-20290 SD77 Project No 80580OSD SUMMARY OF MONITORING SERVICES The following summarizes the activities SDII observed and documented at the site: • Between March 10 and March 21, 2014, Certified Foundations, Inc. installed 46 steel helical pipe piles along the exterior of the residence which comprised of 1,216 linear feet of steel piling advanced into the subsurface. • The installed helical piles had 1-1/2 inch square shafts (Chance SS150) with lead sections consisting of a 10-inch diameter helix followed by an 8-inch diameter helix (Chance C150-0490). • Installation torque ranged from 5,130 to 6;398 foot-pounds and installed tip depths ranged from 20 to 38 feet. 4! Following installation, the .piles and foundation brackets were initially seated at 1,500 _ pounds per square inch sr Final lift pressures ranged from 1200 to. 2 200 PSI. _ Y • The contractor used the installed helical underpinning piles and hydraulic tams to support the foundation and close any cracks on the exterior of the home. The perimeter, of the residence was lifted between 3/8 and 2 inches. Based on our observations, the underpinning pile installations were documented as' substantially., complying with SDII's recommendations. Table 1 in, the Appendix summarizes the ,pin pile installation. Figure 2 illustrates the location and numbering of the -pin pile locations. It is SDII's understanding that cosmetic repairs, will be done following the pin pile*installation..' Accordingly, any existing damage and/or collateral damage associated with the .pin pile t` " installation program and the previously performed compaction grouting operations should be" ' repaired at that time by a qualified restoration contractor. f F Im L E OPY Completion Report of Underpinning Ret', ,ion March 3I, 2014 Lyshon residence - Fort Pierce, Florida Claim No. 009-20290 SDII Project No 8058005D CLOSING SDII appreciates the opportunity to have assisted you on this project.

Figure 1 illustrates the project location. It is noted that SDII completed a subsidence investigation at the subject residence and was detailed in our Final Report — Subsidence Investigation dated August 21, 2013. In our report, it was SDII's opinion, within a reasonable professional probability, that sinkhole activity, as defined by Chapter (§) 627.706(2)(i) Florida Statutes (F.S.), did not exist at the Lyshon residence and that the observed damage to the structure is most consistent with either the direct result, or the collateral effect, of differential foundation movement. The observed conditions were structurally significant in that they compromise the load capacity of primary structural members or systems. The differential movement of the foundation was primarily attributed to the shallow organic -rich soils that were encountered onsite and evident in SPT B-1. These soils are susceptible to compression as a consequence of organic decomposition, resulting in settlement. Also contributing to the differential foundation movement are the encountered near -surface sandy soils are also susceptible to consolidation and/or settlement. These conditions are a result of various factors including variations in applied structural loads through the foundation, variable soil relative densities, seasonal fluctuations in groundwater levels, surface soil erosion, and stormwater runoff and percolation. These factors can occur at varying points during a structure's lifetime and need not be contemporaneous. These factors can contribute to long-term settle der tial movement of the foundation. SDII has been d p 0V'OPY recommendations for stabilizing the foundation of a fff��� sif Foundation Stabilization Recommendations Lyshon Residence —Fort Pierce, Florida Claim No. 009-20290 SDI/Project No. 86k05C Paget of 3 Based on the slope of the floor slab and the damage observed, SDII recommends that the foundation of the structure be stabilized and releveled through the installation of helical piles around the perimeter of the structure. The intent of the helical piles is to resupport the foundation/slab such that the helical flights will bear on the medium dense sands encountered between 20 and 35 feet bls. The installation of the underpinning piles will lift, support, and relevel the structure, closing the relatively wide cracks that have opened. The underpinning helical pile assembly, including mounting bracket, is to have a minimum load capacity of 30 kips. The contractor is to submit the proposed helical pile system to SDII for approval. The underpinning helical piles should be installed around the perimeter of the structure as shown on Figure 2. These piles should be advanced to bear on the medium dense sands between 20 and 35 feet bls (estimated average of 30 feet). The lead section flights (likely 3 flights will be necessary) shall be capable of bearing a 30-kip load. The final bearing capacity will be determined in the field based on the final achieved torque as per the manufactures specifications of the equipment utilized. Helical bearing capacities shall be confirmed by the overseeing geotechnical engineer. Flight configuration and pile installation methods must be submitted to SDII for approval. Helical pile spacing should be approximately 6 feet on center and should not be located more than 3 feet from any corner unless a spreader beam is utilized and should not be located under any window or ,opening unless approved by the overseeing engineer. An estimated 46 piles will be required at the approximate locations shown on Figure 2. These locations may require adjustment by the contractor based on site conditions but the overseeing engineer must approve any adjustment. It is important to note that the optimum level to which the structure can be lifted as a result of the underpinning process is a function of the structural configuration as well as the amount of long- term and irreversible stresses that have accumulated. It may not be practical to attempt to completely relevel the structure, as excessive collateral damage may result. Following the underpinning, any remaining releveling that is needed should be accomplished through cosmetic repair techniques. It is our recommendation that the structure be carefully monitored during the lifting process. It should be noted that the contractor is responsible for the means and methods of construction. A list of estimated costs for repair and engineering supervision is provided below. It does not include estimates for cosmetic repairs, which should be estimated by a qualified insurance adjustor or contractor. Cosmetic repairs should be postponed for 30 days after the installation of the helical piles to allow for any subsequent structure movement to occur. A.

This will also allow the engineer who created the foundation stabilization design to certify that the stabilization met design specifications. It should be noted that the contractor is responsible for the means and methods of construction. SDII appreciates the opportunity to have assisted Frontline Homeowners Insurance on this project.

Sincerely, FILE SDII GLOBAL CORPORATION COPY ,f Subsidence Investigation SDIi'rioject Number: 8058005B Lyshon Residence — Fort Pierce, Florida EXECUTIVESTTWUAPY Frontline Homeowners Insurance retained SDII Global Corporation (SDII) on July 30, 2013 to conduct a subsidence investigation, including a structural damage evaluation at the Lyshon residence in Fort Pierce, Florida. The purpose of the. investigation was to determine if sinkhole activity and structural damage exist at the property and, to the extent possible, the probable causes contributing to the observed damage, especially structural damage, at the property. SDII previously completed a Structural Damage Evaluation (SDE) and a Residential Damage Assessment (RDA) at the Lyshon residence to determine if structural damage exists at the property and, to the extent possible, determine the probable causes contributing to the damage, especially structural damage, at the property. SDII issued the RDA and SDE reports to Frontline Homeowners _Insurance dated May 16, 2013 and August 19, 2013, respectively. The conclusions of the SDE evaluation are incorporated into this report. Please refer to the RDA and SDE reports for the observed and reported damages, and an evaluation of said observations and structural damage to the residence. The following methods were utilized in our investigation: • A site inspection and an owner interview were completed to identify local conditions, record specific concerns, establish a history of the structure, determine a timeline of observed damages, and obtain details of the construction of the structure. • Damage to the structure was documented, photographed, and mapped (Figure 2). • A Ground Penetrating Radar (GPR) survey was conducted around the perimeter and inside of the structure to identify anomalous subsurface areas within the zone of influence of the foundation and in other areas of interest (Figure 3). Wall scans were also conducted along the exterior walls of the structure where applicable. • Test pits were excavated to directly observe foundation construction and geometry (Figure 4). • Hand auger (HA) borings and push penetrometer soundings were advanced to determine the composition and strength of subsurface materials near the foundation and the upper zone of influence of the structure (Figure 4). • Standard Penetration Test (SPT) borings were advanced adjacent to the foundation in order to characterize the relative stability of soils within the zone of influence of the structure and to investigate deeper geologic conditions for the presence of evidence of sinkhole activity (Figure 4). • Laboratory testing of soils was performed to identify deleterious soil types and for quality control of soil and geologic materials classification. • Relative floor elevation contour mapping was completed to identify anomalous floor elevation trends and establish a baseline contour map of the existing floor elevation (Figure5). FILE COPY iii Subsidence Investigation Lyshon Residence — Fort Pierce, Florida SDIi r`roject Number: 8058005B • A limited visual, non-destructive structural assessment was completed by an engineer in the field to identify construction methods and structural deficiencies related to the potential causes of observed damage. • Specific structural observations and measurements were made to allow for determination of the conditions considered to reflect structural damage. • ASTM International (ASTM) standard methods, where available, were generally utilized in this scope of work. Otherwise, industry standard methods were employed. Methods of data collection are explained and cited in Appendix A. This final report was prepared to summarize the results of the subsidence investigation and reiterate the results of SDII's Structural Damage Evaluation. If sinkhole activity is identified, this report also includes SDII's recommendations for remediation. This report provides conclusions concerning whether sinkhole activity and structural damage exist. It is SDII's opinion, within a reasonable professional probability, that sinkhole activity, as defined by Chapter (§) 627.706(2)(i) Florida Statutes (F.S.), does not exist at the Lyshon residence. The SPT boring data do not indicate the presence of sinkhole activity at the site. The N value patterns observed in the SPT borings are consistent with normal compaction of sediments, changes in stratigraphy, an increase in the clay content, and/or depositional features related to the geology of the Eastern Valley Physiographic province of St. Lucie County. There were no indicators of settlement or systematic weakening of the earth supporting the residence resulting from contemporaneous movement or raveling of soils, sediments, or rock materials into subterranean voids created by the effect of water on a limestone or similar rock formation. The generally lateral continuity of the stratigraphy, as well at the relatively similar N value patterns observed in the SPT borings, indicates that the sediments have not been disturbed by sinkhole activity. It is SDII's opinion, within a reasonable professional probability, that structural damage, §627.706(2)(k) F.S., exists at the Lyshon residence. The observed damage to the main structure qualifies as excessive foundation displacement or deflections. As structural damage, as defined in §627.706(2)(k) F.S., has been identified and the presence of sinkhole activity, as defined in §627.706(2)(i) F.S., has been eliminated, SDII certifies that this investigation was of sufficient scope to determine the absence of sinkhole loss, as defined in §627.706(2)0) F.S., and the presence of other cause(s) of damage within a degree of reasonable professional probability as specified in §627.7072 F.S. and §627.7073 F.S. The observed damage to the main structure is most consistent with either the direct result, or the collateral effect, of differential foundation movement. The observed conditions are structurally significant in that they compromise the load capacity of primary structural members or systems. The differential movement of the foundation is primarily attributed to the shallow organic -rich soils that were encountered onsite and evident in SPT B-1. These soils are susceptible to compression as a consequence of organic decomposition, resulting in settlement.

The SPT boring data do not indicate the presence of sinkhole activity at the site. The N value patterns observed in the SPT borings are consistent with normal compaction of sediments, changes in stratigraphy, an increase in the clay content, and/or depositional features related to the geology of the Eastern 'Valley Physiographic province of St. Lucie County.

The SPT boring data do not indicate the presence of sinkhole activity at the site.

The observed damage to the main structure qualifies as excessive foundation displacement or deflections. As structural damage, as defined in §627.706(2)(k) F.S., has been identified and the presence of sinkhole activity, as defined in §627.706(2)(i) F.S., has been eliminated, SDII certifies that this investigation was of sufficient scope to determine the absence of sinkhole loss, as defined in §627.706(2)0) F.S., and the presence of other cause(s) of damage within a degree of reasonable professional probability as specified in §627.7072 F.S. and §627.7073 F.S. The observed damage to the main structure is most consistent with either the direct result, or the collateral effect, of differential foundation movement. The observed conditions are structurally significant in that they compromise the load capacity of primary structural members or systems. The differential movement of the foundation described below is primarily attributed to the shallow organic -rich soils that were encountered onsite and evident in SPT B-1. These soils are susceptible to compression as a consequence of organic decomposition, resulting in settlement. Also contributing to the differential foundation movement are the encountered near -surface sandy soils are also susceptible to consolidation and/or settlement. These conditions are a result of various factors including variations in applied structural loads through the foundation, variable soil relative densities, seasonal fluctuations in groundwater levels, surface soil erosion, and stormwater runoff and percolation. These factors can occur at varying points during a structure's lifetime and need not be contemporaneous. These factors can contribute to long-term settlement and differential movement of the foundation. These conclusions are based upon the following: • The SPT borings indicated typical N values for the soils throughout the extent of the SPT borings performed at the site. Voids or raveling soils indicative of sinkhole activity were not observed during the completion of the borings. FILE COP4-1 Y Subsidence Investigation Lyshon Residence — Fort Pierce, Florida SDII rroject Number: 8058005B The hand auger and SPT borings indicate the near -surface soils consist of very loose to medium dense sands. Very loose and loose sandy soils are susceptible to long-term settlement from variations in applied structural loads through the foundation, variable and/or inadequate soil compaction, seasonal fluctuations in the groundwater table level, surface soil erosion, surface -water runoff, and groundwater percolation. • Laboratory testing of soil samples from 6 to 8 feet bls in SPT boring B-1 returned an organic content of 12.3 percent by weight. Soils with organic contents greater than 5 percent by weight are generally considered unsuitable for foundation support due to compression as a consequence of organic decomposition, resulting in settlement. FILE COPY 4-2 Subsidence Investigation SDii`t•roject Number: 8058005B Lyshon Residence — Fort Pierce, Florida 5.0 LIMITATIONS 5.1 Ground Penetrating Radar According to ASTM D6429, GPR is the preferred method for investigating "voids and sinkholes". This method provides high -resolution data with a minimum of interferences. GPR has been used in similar investigations to help identify shallow subsurface conditions frequently associated with karst features. In many cases, a GPR investigation has resulted in the identification and mapping of the boundaries of karst features and has helped characterize their size and geometry. This method, however, is limited to the ability of the GPR unit to collect interpretable data. There is a possibility that karst features may exist at the project site and not be detected by the GPR technique due to small size, subsurface soil conditions, or the occurrence of such karst features below the depth of penetration of the GPR signal. Note that many GPR anomalies are not sinkhole or karst features. The presence of an anomaly should not be construed to reflect sinkhole activity simply because of its existence. 5.2 Standard Penetration Test and Hand Auger Borings The determination of soil type and conditions was only done from the ground surface to the maximum depth of the borings. Any changes in subsurface conditions that occur between or below the borings would not have been detected or reflected in this report. Soil classifications are based upon identifiable textural changes, color changes, changes in composition, or changes in resistance to penetration at the intervals from which such samples were collected. Abrupt changes in soil type, as reflected in boring logs and/or cross sections, may actually represent gradual transitions. Depth to the water table is based upon observations made while advancing hand augers and SPT borings. The maximum depth of hand auger borings is 10 feet bls unless otherwise noted. Water table depth is an estimate and does not reflect annual or extreme variations that occur due to fluctuations in rainfall, pumpage, and rates of evapotranspiration. Low permeability soils or sediments may not allow water to freely enter the borehole and, therefore, the water table may not be evident or it may only represent a transient condition. The depths are estimated from the immediate land surface, which is not surveyed or tied to a known reference elevation. 5.3 Site Figures and Conditions Described in this Report The measurements used for the preparation of figures in this report were made with a fiberglass measuring tape or measuring wheel. Such measurements are usually accurate to within ±5 percent. Right angles were estimated from existing exterior walls at the structure; such angles are usually accurate to within 5 degrees. Figures in this report were not prepared by a licensed land surveyor and should not be interpreted as such. The construction and damage to the structure(s) investigated by SDII are subject to change. The conditions described in this report are, to the best of our knowledge, c LEr the time of the investigation, but they may not reflect historical or post -investigation cor i 5.4 Use of This Report The conclusions, anal sis, and o inions ex ressed herein have been prepared within aeasono�� Y P P degree of professional certainty.
