As-built drawings is a specialized skill in the field of architecture and engineering that involves creating detailed drawings and documentation of a project or structure as it is built. This process requires a thorough understanding of design specifications, construction materials, and building codes to ensure accuracy and completeness of the as-built documentation. As-built drawings are important for future maintenance, repairs and renovations, and are often required for legal and regulatory compliance. They provide a detailed record of the project's construction and allow for a comprehensive understanding of its structure and components.
