What can shims be used for in the installation of base plates on footings?

Shims are essential tools used in construction and installation, particularly for achieving proper alignment and leveling. When installing base plates on footings, shims are employed to provide the necessary leveling adjustments. This is crucial because footings may not always be perfectly level due to variations in the ground or other factors.

Using shims allows for a precise fit, ensuring that the base plates are level and stable. A level base plate is vital for the overall integrity of the structure being built, as it helps distribute loads evenly, reducing the risk of structural issues down the line. Without shimming, imperfections in the footing could lead to misalignments, uneven weight distribution, or even failure of connections and components.

The other options do not address the primary purpose of shims as effectively as leveling adjustments. While enhancing durability and reducing friction are important considerations in construction, they do not capture the specific function that shims serve in the context of base plate installation. Increasing surface area is not relevant in this scenario, as shims are more about creating a suitable elevation and leveling rather than changing surface areas.
