As-built plans are detailed drawings that depict the actual construction and layout of an existing commercial building. These plans are important for several reasons: Building maintenance and repair: As-built plans provide important information about the building's structure and systems, which is essential for maintaining and repairing the building. Building upgrades and renovations: As-built plans are used to plan and execute upgrades and renovations to the building. They allow contractors and engineers to understand the existing conditions and plan accordingly.

Building code compliance: As-built plans help ensure that the building is up to code and complies with all local, state, and federal regulations. Real estate transactions: As-built plans are often required for real estate transactions, as they provide information about the property's condition and any potential issues. Legal disputes: As-built plans can be used as evidence in legal disputes, such as construction defects or zoning violations. Overall, as-built plans are an important tool for managing and improving existing commercial buildings. They help ensure that buildings are safe, compliant, and functional for their intended use.
