Know Something About As-Built Drawing and Its Importance In Post-Construction

1. Know Something About As-Built Drawing and Its Importance In Post- Construction Have you ever wondered how builders and facility managers keep track of every change made during construction? The answer is As-Built Drawings. These are a critical component of any construction project that serves the final set of drawings that reflect all changes made during the building process. Unlike design or construction drawings, which are created before or during construction, as-built drawings Auckland provide an accurate representation of the finished structure, including any modifications, deviations, or on-site adjustments that occurred during construction. As a result, they are essential for future renovations, facility maintenance, and legal documentation, ensuring that building owners, contractors, and engineers have a reliable reference for the life of the structure. If you want to delve deeper, then this content is for you. How Important Is As Built ? You know that all engineering work has as its main references the architectural and executive projects of the project that will be built, right?

2. However, it's natural that, during construction, new changes are made, modifying the original design. The same occurs throughout a building's lifespan, when renovations and adaptations are invariably carried out by users. Therefore, it's to be expected that the initial technical design will undergo changes throughout the building's lifespan. A complete and reliable record of all these modifications is essential. Do you know why? So that, in the future, renovations and maintenance can be carried out without compromising the quality of the constructed structure. This is precisely what As Built is all about. It lists all the changes made to a civil engineering project during its construction and use. Technically and formally recording any undocumented changes helps prevent potential accidents that may occur when working on older properties. Main Types of “As Built” Projects : Therefore, it can be classified into several types. Each type involves a survey of the facilities based on their specific characteristics, as shown below : Architectural As-Built- Includes a complete survey of the building, including interior areas and facades. This type of As-Built includes the dimensions and geometric measurements, as well as details on the materials used in sealing, roofing, and cladding. Electrical As-Built- As you might expect, this type of As-Built involves surveying the entire electrical installation and analyzing circuit layout, energy demand, components, and the number, power, and location of power points. As-Built Plumbing- This identifies the various installations that make up the plumbing and plumbing system. It includes all the locations, piping dimensions, and branching, both for hot and cold water. Other typologies- As Built can also be carried out to analyze the voice and data communication system, fire prevention, air conditioning, among other disciplines. What Is The Difference Between Construction Drawings And As-Built Drawings ? Construction drawings : The construction drawing is the basis for construction and the basis for cost budget. Construction personnel shall carry out construction according to the construction drawing and ensure that the

3. construction is carried out strictly in accordance with the construction drawing during the construction process. All construction drawings are produced by the design institute. During the construction process, many design changes will occur due to modifications made by the owner, etc., and they are the main basis for construction. As-built drawing : After the project is completed, the construction unit draws the actual construction situation on the original drawing based on the effective changes in the design modification, technical verification, etc. The completion drawing is drawn by the construction unit and reflects the actual completion status of the house. After the project is completed, the construction unit is responsible for compiling it according to the requirements of the completion drawing and sending it to the archives bureau for archiving. Conclusion While construction drawings serve as the foundation for any building project, they are often subject to modifications during the construction phase due to on-site changes, design updates, or unforeseen conditions. In contrast, As-Built Drawings are prepared after the construction is fully completed, capturing the final, accurate representation of the built structure. These drawings are considered the definitive record and should not be altered once finalized. They must be properly archived for future reference, maintenance, or renovation work.
