(TX), MBA Austin | Dallas | Fort Worth | Houston |San Antonio | Waco (469) 751-7694 www.CrosstownEngineering.com Date: April 24, 2025 Attention: Atlas Foundation Co., Inc. (via e-mail) Subject: Structural Foundation Initial Inspection Report 3914 Meadow Dr., Grapevine, TX. 76051 To Whom It May Concern: Crosstown Engineering (CE) was retained to conduct a review of the provided pier plan prepared by Atlas Foundation Co., Inc. to determine if it is a reasonable limited plan of repair. CE visited the subject site to interview the property owner, observe the structure and terrain, and to verify the floor elevation data. We observed brick cracks, drywall cracks, ceiling cracks, window separations, frieze board separations and trim separations that indicated settlement was occurring on the right and front sides of the structure. These observations are confirmed by floor elevation data. Atlas Foundation Co., Inc. has proposed to perform the following in the approximate locations of the structure as indicated on the limited repair plan to support the foundation: x Obtained a ground penetrating radar scan to identify interior concrete beam within the slab. x Install 25 total pilings (17 exterior, 8 breakouts). The foundation repairs are to meet or exceed 2021 IRC. Based on our observations, it is our opinion that the proposed plan of repair is reasonable. Because the structure has endured pre-repair foundation differ- ential movement, residual differential elevation and perceptible floor slope may remain following the lim- ited foundation repairs. This limited repair plan is intended to provide a reasonable repair to improve the performance of the foundation and is not intended to level the foundation. The contractor shall determine the amount of elevation correction needed based on the reaction of the structure during the lift in order to minimize damages and additional stress. Please see the Disclosure & Disclaimer, pier detail (if provided), and limited repair plan for more infor- mation and do not hesitate to call us if you have any questions. Sincerely, Crosstown Land Development Services Texas Engineering Firm (F-15944) Adam Green, P.E. 4/24/25 Professional Engineer (TX #116597) Foundation Report Page 2 of 4 Adam A. Green, P.E. (TX), MBA Austin | Dallas | Fort Worth | Houston |San Antonio | Waco (469) 751-7694 www.CrosstownEngineering.com DISCLOSURE & DISCLAIMER It is known to knowledgeable professional engineers that the soils in this area are subject to movement due to expan- sion, contraction or densification of the soils etc. This soil movement could possibly cause the foundation to move after the remediation plan within the attached report has been implemented and may impact the stability of the foun- dation and cause damage. NO WARRANTY IS EXPRESSED OR IMPLIED BY THIS ENGINEER AS TO THE PERFORMANCE OF THIS FOUNDATION OR THE REPAIRS THERETO. Diligent foundation maintenance to maintain consistent soil con- ditions along the perimeter should reduce further problems after the recommendations within this report have been implemented. However, seasonal moisture variations, water leaks, erosion and other factors may affect the stability of the foundation and put it in danger of further damage. REPORT LIMITATIONS This report is written for informational purposes only and is not intended to be a detailed technical evaluation of the property or an inventory of defects.

The client agrees that neither CLDS nor its employees or owners will be responsible for: 1.Knowledge of the subsurface conditions without extensive geotechnical data obtained from onsite drilling and testing of the recovered samples, 2.Knowledge of cracks, vertical differential displacement of floors without uncovering of the floor by the client; and 3.Any other element such as joists or beams and other structural members that is boxed or otherwise not readily available to CE for viewing, and releases CE from any liability attributable to such knowledge or conditions. Any prescribed repair or maintenance plan detailed by this report is based on observations of apparent performance of the facility at the time of this structural survey. Compliance with any code or specification other than as express- ly noted is specifically excluded.
