DESCRIPTION All descriptions of the structure are based on observation from Silver Mountain Drive. The front of the home is assumed to face South West for the purpose ofthis report. This structure is a 2-story single-family home reportedly originally built in 2005. The exterior is wood batten siding. The roof is an asphalt shingle gable design. Gutters and downspouts were observed. No foundation or as-built construction drawings were available for review for this project. No soils testing was available for this report. ANALYSIS The homeowner has requested stabilization and lift for the structure. The garage area is concrete slab on grade.The main structure is built over a crawlspace with foundation footer and stem walls. There are two steel wide flange beams running from the front to rear of the structure. These beams are bearing on beam pockets in the stem wall on both ends of the beam. No adjustable steel jacks are supporting wide flange beam load. The crawlspace has a vapor banier and insulation on the inside of the foundation stem wall limiting visibility. (¡ þ oÀ LICENSED PROFESS¡ONAL ENGINEERg HOME AND BUILDING INSPECTION. STRUCTURALEVALUATION DESIGN COMMI JNITY ASSOCIAÎON SFRVICFS @ Seismic activity is not considered a factor in respect to this project. 360'maximum frost depth is assumed for this location. The water table is typically approx. 15-35 ft. Shallow or perched water can exist seasonally especially if poor drainage occurs close to the structure foundation. Proper grading of the soils around the perimeter of the home and moving water away from the foundation is important with any home: o The homeowner should maintain a positive drainage slope away from the structure for 360 degrees around the structure -6" minimum slope every l0 ft. o The perimeter within 4 feet lateral distance from the structure shall not be subject to irrigation, either lawn sprinkler spray heads or drip systems. o Gutters and downspouts to be intact and move water at least I ft. away from foundation. o Cracks in foundation walls should be sealed by installing high- strengfh low-shrinkage grout material or equiv. PROJECT SCOPE Install 33 Supportworks 288 push piers to stabilize the foundation walls. The pier spacing varies and spacing shown on the Design Drawing should be maintained. 4'-0" pier spacing is shown at the beam pockets. The installer will need to locate the steel support beams in the field. If cracking at the beam pocket location is observed by the installer after excavation, contact engineer for instruction on installing a new beam between piers to span the foundation crack. Utility locates are recommended to minimíze the risk of any conflicts. Multiple piers should be lifted simultaneously to minimize the potential for breakage of the concrete foundation. Please see enclosed drawing #FR-2023-196 I thru 2 for design details associated with this project. CONCLUSION AND LIMITATIONS This report is valid only for the address and the project scope listed, by the client listed above. The observations described in this document are valid for the date of the observation and have been made under the conditions noted in the report. Use by any other entity or for any other purpose is prohibitecl, without the express, written consent ofthe undersigned engineer. This report is based on published and anecdotal information;variations from the anticipated soil profrles may be encountered; contact the engineer immediately if they are discovered. This report does not cover geological hazards, such as slope süability or landslide. Such investigations require extensive investigative techniques and are well outside the scope of this report. c\ (¡ ð(rô LICENSEÞ PROFESSIONAL ENGINEERS HOME AND BUILDING INSPECTION,.

This report does not express or imply any wananty of the future performance of the structure or drainage condition. This report should not be considered a warranty of condition, and no warranty is implied. The opinions and recommendations presented in this report are based solely on visual observations available for viewing at the time of the site visit and information, if any, provided by the Client and/or their representative(s). We are not responsible for conditions that were not within the scope of our services at the time of inspection. We did not undertake or perform any destructive or invasive testing. No additional subsurface testing, material testing, calculations, nor monitoring over time of the conditions presented in this report are included in this project, but may be obtained, if desired, under separate âgreement. Not included in this site visít was a review of the architectural, mechanical, electrical, plumbing, cosmetic, landscaping, drainage or structural conditions, other than those items specifically discussed, nor a comprehensive review of compliance with applicable building codes. The work covered by this project is not held out as being a complete repair for all known or suspected structural or foundational issues within the building; other work may be justified or needed, but work not included is outside the scope of this project. If it is required at a future date, it will be under a separate contrâct. This report has been prepared for your benefït and in strict confidence with you as our client.
