As built drawing : An "As-Built Drawing" (also known as a "Record Drawing" or "As-Constructed Drawing") refers to a set of plans or blueprints created after the construction of a project, reflecting all modifications and changes made during construction. These drawings document the final design of a project, showing the precise locations and dimensions of all elements as they were actually built, rather than how they were originally planned. Here are some key details typically included in an As-Built Drawing: 1. Accurate Dimensions and Coordinates: Final measurements of the structure or system (e.g., foundation, walls, doors, windows). Coordinate locations of all building components and utilities, reflecting what was actually constructed. 2. Modifications from Original Plans: Any changes or deviations from the original construction plans, such as repositioned walls, doors, or utilities. Alterations during construction, like adjustments for unforeseen site conditions, design changes, or material substitutions. 3. Material Specifications: Details of the materials used, including any changes from what was initially planned. Supplier and product details for components that were substituted or modified. 4. Utility and Service Lines: Accurate locations of all underground utilities such as sewer lines, water lines, electrical, gas, and communications. Locations and specifications of HVAC systems, electrical panels, and plumbing connections. 5. Construction Details: Structural elements such as beams, columns, foundations, and floor slabs. Any specific construction techniques or features used, including those that differed from the design. 6. Finished Floor Elevations: The elevations of finished floors, including levels for landscaping, foundations, and any special drainage or slope conditions. 7. Elevations, Sections, and Views: Updated elevations and sections reflecting any architectural changes. Views of the site to show how the project was constructed relative to neighboring elements or infrastructure. 8. Compliance and Approvals: Inspection and approval marks from authorities or project stakeholders, confirming the construction matches the approved plans. Permits and regulatory notes indicating that the construction complies with applicable codes and standards. 9. Survey Information: Topographical survey data if there were changes to the landscape during construction. Boundary lines and property lines that may have been adjusted during construction. 10. Final Location of Equipment and Appliances: For mechanical, electrical, and plumbing (MEP) systems, final locations of equipment such as HVAC units, water heaters, and electrical outlets. 11. Documentation of Changes: A summary of all changes from the original design, with reference to who authorized the change and the reason behind it (e.g., client request, regulatory requirement, unforeseen issue). 12. As-Built Symbols and Notations: Symbols and annotations specific to the as-built format, often using different colors or line types to differentiate between the original design and the changes. In summary, as-built drawings are critical for the operation, maintenance, and future renovation of a building or project, ensuring that anyone involved in the building’s lifecycle can understand how it was actually constructed. These drawings are often required at the end of construction projects for building owners, engineers, or architects to ensure everything complies with the intended design and regulations. www.bechennai.com.
