Crosstown Engineering (CE) was retained to conduct a review of the limited foundation repair plan prepared by Advanced Foundation Repair (the contractor) to determine, in our opinion, if the recommended remediation plan is a reasonable plan of repair based on the relative elevation map provided. The contractor provided a limited repair plan that included the pier locations and pre -lift elevations for the structure for our review. No other information was provided regarding prior engineering reports, recommendations for foun- dation repairs or construction documents relative to this structure. If existing piers are shown in the limited repair plan, their locations were provided by the client and are approximated. We do not certify their performance or exist- ence. If the reader would like to determine if they are present, they must contact the owner or contractor to obtain an engineering certificate for them. CE has not performed a visual inspection of the structure. The slab -on -grade foundation has settled towards the areas where piers are located on the limited repair plan and physical damage is present which indicates a need for remedial measures according to the contractor. Advanced Foundation Repair has recommended performing the following in the approximate locations of the struc- ture as indicated on the limited repair plan: • Installing 11 total pilings (10 exterior, 1 breakout). Upon review of the elevation drawing and based on the contractor's evaluation of the property, we believe the pro- posed limited repair plan to be a reasonable and limited repair.

Moving forward, we anticipate that some cracks in the interior and exterior walls will surface due to seasonal movement within the soils, even after foundation repair. Periodic repair of this type of cracking may be needed. A foundation and yard watering and foundation maintenance program will help control seasonal movement. It is important that the soils be stabilized and maintained with grass or ground cover around the perimeter of the structure. In addition, tree and shrub removal or root barrier installations are advisable if trees or bushes are observed to be close to the foundation. Tree roots can cause "heave" or settlement of the foundation where roots grow and absorb moisture over time when planted close to the foundation (tree roots extend approximately as far or further than tree limbs). Maintaining the soils around the structure to slope away from the foundation to prevent excessive ponding near the foundation in areas that are not already sloping away will help prevent future foundation movement. We recommend that a full gutter system with gutter extensions be maintained to discharge a minimum of 4 feet from the foundation (not in landscaped flower beds or any other location that will trap water near the foundation). Ponding near the foundation can cause "heaving" (upward movement of the foundation), settlement of the foundation due to overly saturated clays soil or erosion of soil embedment around the foundation. If the owner, at any time, observes standing water near the foundation, we recommend that they consult with an engineer or a drainage contractor immediately. We recommend pre -lift and post -lift plumbing tests be performed on the sewer and potable plumbing lines. All leaks shall be repaired immediately. Disclaimer: We do not warrant the future performance of the subject foundation and the reader is urged to review the Disclosure & Disclaimer for other limitations and standard recommendations.

Wor(k (169) 7 1-7691, Attention: Advanced Foundation Repair and Property Owner (via email) Subject: Post -Repair Foundation Repair Evaluation Slab Foundation 728 Heather Wood Dr, Grapevine, TX Good Afternoon: ` Advanced Foundation Repair (the contractor) retained Crosstown Engineering (CE) to visually inspect foundation repairs completed by Advanced Foundation Repair. This report provides our reasonable professional opinion of the condition of the foundation on the date of our inspection and does not take into consideration any changes in the condition of the foundation or soils after that date. The contents of this report supersede any verbal comments made regarding the structure before, during or after the inspection and this report was prepared for exclusive use of the person or persons this report was prepared for and we do not have any obligation or contractual rela- tionship to any other party other than the party this report was prepared for. Observations for compliance with any code or specification other than those explicitly stated are not included. Scone of Work: The subject foundation was visually inspected and a floor elevations survey was performed in areas that were accessible at the time of the inspection. The opinions provided within this report are based on the experience and judgment of the inspector and the information provided at the time of the inspection. This report also gives engineering advice with regard to the best and most economical repair method assuming normally expected subsurface conditions and conventional construction methods. It is known to all educated engineers with knowledge of the active soil supporting the structure that a full repair plan would include the underpinning of the entire structure and is not economically feasible due to the cost vs. benefit and the risk of resulting damages. Scope of Work Limitations: This report is for informational purposes only and is not intended to provide a detailed inventory of defects or a technical evaluation of the structure, drainage system or the overall property. The inspection excludes plumbing tests or procedures, verification of previous foundation repairs, framed superstruc- ture, detached buildings, privacy or retaining walls, general site drainage away from the structure, ma- terial and soil sampling/testing, and verification of concrete reinforcement or knowledge of the location of interior grade beams, boxed structural members not in plain sight or previous repair work. The client or individual ordering this report agree that Crosstown Engineering is not responsible for knowledge of the subsurface conditions without extensive geotechnical investigation including on -site drilling or testing of samples. 1 of 6 CROSSTOWN-, 1'milpa: (813) 702 -3i348 j 11dhv; .). Wonh 1469) 7 rii-769I The future performance of this foundation cannot be predicted due to variables out of the control of the inspector. Therefore, this report does not predict or warrant the future performance of the subject foun- dation and the reader is encouraged to read the entire report. Document Review: The contractor provided a limited repair plan that included the pier locations and pre -lift elevations for the structure for our review. No other information was provided regarding prior engineering reports, recommendations for foundation repairs or construction documents relative to this structure. If existing piers are shown in the limited repair plan, their locations were provided by the client and are approxi- mated. We do not certify their performance or existence. If the reader would like to determine if they are present, they must contact the owner or contractor to obtain an engineering certificate for them. Documents that provide original structural design drawings, design conditions, or "as -built" drawings or slab elevations at the time of construction were not available at the time of the inspection. Therefore, knowledge of interior grade beam locations or other foundation information is unknown. General Observation: For the purposes of this report directions will be described using the terms left, right, front, and back with the front referring to the side of the structure indicated on the limited repair plan. The structure is two stories tall with a slab -on -grade foundation. The primary structural system of the structure is a wood framed system with exterior brick veneer, exterior wood siding, interior wallpaper and interior drywall with various finishes. The foundation was not exposed during our inspection and was covered with various floor -covering types. Gradinv. Drainaee. Erosion and Vegetation Observations:. The terrain immediately surrounding the structure was visually observed during the inspection. We observed the following: • The gutter system is adequate. • The drainage system is adequate. • The terrain is landscaped with grass, several trees, and some shrubbery. Some trees and/or shrubs are close to the foundation. • Disturbed soil in the area of the repairs was observed. Floor Elevation Discussion: A relative elevation floor survey was performed using a Ziplevel Pro-2000B to map the surface topog- raphy of the floor of the living area and garage (if present). The floor plans and the elevations are illustrated on the limited repair plan. The elevations were adjusted based on the flooring type encoun- tered to be on the same plane as the base point floor type. If a garage was present, the garage ceiling was measured and adjusted to be on the same plane as the foundation. Garage floors are designed to slope and are not as effective in measuring foundation movement. 2of6 40 0 0"F Adam A. Grccn, P.L. (FL a_ TX), lA4il.1 CROSSTOWNainpa: (813) 3398 I Dallas' 1. \i'ol th (169) 7.51-7601 11- Observations: Based on our observations and review of the limited repair plan provided by the contractor, the structure has experienced general foundation movement over the life of the structure, resulting in the front, right and back side of the structure being low with respect to the rest of the structure. Brick cracks, drywall cracks, ceiling cracks, window separations, and trim separations were observed. Foundation Repair Details: Advanced Foundation Repair performed the following in the approximate location of the structure as indicated on the limited repair plan: • installed 11 total pilings (10 exterior, 1 breakouts). The purpose of the installation was to provide support and mitigate downward movement in the areas of the installation. To the best of our knowledge the contractor has performed the limited repairs in substantial conformance with their provided limited repair plan and our pre -repair report dated 1/14/20, including any approved changes. Maintenance Opportunities: We recommend post -lift plumbing tests be performed on the sewer and potable plumbing lines and any leak be immediately repaired. The results of the tests should be provided to our office. Maintaining a fully functioning gutter system will minimize ponding, soil loss and erosion, and will help control seasonal movement near the foundation. The gutter system should direct storm -water discharge away from the foundation through downspouts to a well -drained area that is graded away from the foun- dation. Optimally, we recommend the gutter system discharge via in -ground solid pipe to a low-lying area far away from the foundation. Vegetation maintenance and a foundation and yard -watering program will also help control seasonal movement. Maintaining consistent moisture levels in supporting soils at all times of the year is neces- sary. It is important that the soils be stabilized and maintained with grass or ground cover around the perimeter of the structure to prevent erosion and an exposed or improperly embedded foundation. Large to medium-sized trees, and even large or numerous shrubs, growing too close to a foundation can dra- matically effect the moisture content of the soils within the zone of influence beneath the structure. Root systems extract large quantities of water from underlying soils and result in large volumetric changes in the soils (shrinkage). As the tree absorbs water from the soil and the soil volume decreases, the foun- dation will settle in unsupported. If problematic roots are observed, we recommend removal or instal- lation of tree root barriers. Grading of the soils around the foundation is a critical element to your foundations health. Sloping the soils away from the home and preventing water from ponding near the foundation is needed to prevent soil "heave". If ponding is noticed near the foundation during the rainy season, consult with an engineer or a drainage contractor immediately. Over -saturated soils can cause "heave" or settlement and contrib- ute to foundation movement. 3of6 ROSSTOWN. Expectations of the Limited Foundation Repairs:. Adam A.

Aworth (469) 7,51-769 1 This limited repair plan is intended to provide a reasonable repair and to improve the foundation and is not intended to level the foundation. The contractor determined the amount of elevation correction needed based on the reaction of the structure during the lift in order to minimize damages and additional stress. Because the structure has endured pre -repair foundation differential movement, residual differential el- evation and other cosmetic issues may remain following the foundation limited repair, such as interior and exterior wall distress, door sticking, and doorway leaning. The soils beneath and surrounding the structure are known to shrink and swell as the seasonal soil mois- ture content fluctuates. Moving forward, we anticipate that some cracks in the interior and exterior walls will surface due to seasonal movement within the soils, even after foundation repair (if performed). Periodic repair of this type of cracking may be needed. However, if cracks appear to worsen and there are new indications of foundation movement, we recommend re-evaluating the structure. Underpins (a.k.a. Pilings or Piers) are constructed of steel or concrete and cost and performance will vary. Generally speaking, the deeper a piling is installed, the better it will perform. Shallow installations may be acceptable if they are terminated into rock. This information is meant to serve as a guideline and the owner must decide a reasonable cost/benefit on the property. Piling design is best done with data from a site -specific soils investigation. Such an investigation was not provided and is not a part of this scope of work but we strongly recommend obtaining this data. If this data is not provided, our pier design is only intended to be a minimum standard based solely upon average soil conditions in the general location of the property and as such, may not necessarily provide maximum performance. 4of6 CROSSTOWN Disclaimer: Adam A.
