An existing foundation assessment evaluates the condition, design, and construction quality of a foundation to identify potential concerns such as settlement, cracking, or structural deterioration. This type of investigation is commonly performed when structural damage is observed by the owner. It also helps determine whether the existing footing is adequate to support a proposed addition, lowering of the slab-on-grade, or increasing the room height through structural modifications. The assessment typically includes a visual inspection, field measurements, documentation of existing conditions, and testing to determine the load-bearing capacity of the soil and foundation system.
