As-built drawings are detailed drawings of a building or structure that capture all the changes made to the design during or after construction. They serve as a record of the finished product, including its dimensions, layout, materials used, and any other specifications. As-built drawings provide a comprehensive picture of the completed building or structure, which is essential for contractors, designers, and project managers.
play a critical role in the construction process. They ensure that the construction process runs smoothly, efficiently, and safely. They provide a complete and up-to-date record of the building or structure for future reference, allowing informed decisions to be made during construction. For instance, if a contractor needs to make future changes to the building or structure, they can refer to the as-built drawings to understand the building's current state, making the process easier and more efficient.
In addition to providing a record of the building or structure, as-built drawings also offer valuable information for future maintenance, repairs, and renovations. This information can help building owners and managers understand the building's existing conditions, which can inform the decision-making process for future projects.
What Information do As-Built Drawings Include?
An as-built drawing typically includes the following information:
• Extra work done
• Labels and dates of changes
• Field changes
• Revisions to shop drawings
• Design changes
Having this information documented and readily available can help contractors, designers, and project managers make informed decisions about changes to the building or structure. It also helps to ensure that any changes made to the building are consistent with the original design and meet all necessary codes and regulations.
How are As-Built Drawings Created?
Skilled engineers or designers create as-built drawings with the required technical know-how. The process involves reviewing original specifications and related change documents to document the changes made to the building or structure accurately. The drawings are typically created using CAD (Computer-Aided Design) software, which allows for precise and detailed documentation of the building or construction.
The result is a comprehensive and accurate record of the building or structure that can be used for future reference. It is important to note that as-built drawings should be updated regularly to ensure that they accurately reflect the current state of the building or structure.
In conclusion, drawings play a critical role in the construction process. They provide a complete and up-to-date record of the building or structure for future reference, ensuring that the construction process runs smoothly, efficiently, and safely. They also provide valuable information for future maintenance, repairs, and renovations, helping building owners and managers make informed decisions about future projects.
