What are As Built Drawings?
As built drawings are the completed and finalized construction documents that accurately represent the final design of a building or infrastructure project. These drawings reflect all the changes, modifications, and upgrades that happened during the construction process, ensuring that the final product is in accordance with the required standards and codes. They are considered as essential records for the future maintenance, modification, or renovation of a construction project, and are required to be submitted to the owner or operator upon completion of the project.
As built drawings are typically produced by architects, engineers, or contractors who are involved in the construction of the project. They use as built drawings to record the actual dimensions, layout, materials, and locations of various components of the project, including walls, foundations, electrical, plumbing, mechanical systems, and others.
Why Are As Built Drawings Important?
As built drawings are crucial to ensuring that the final construction product matches the desired specifications and requirements. These documents often reveal unforeseen changes in the original plans, amendments caused by any discovery during the construction process. Inaccurate or incomplete as built drawings can lead to future errors and complications causing a delay in building maintenance, redesigns, or renovation activities.
Furthermore, as built drawings also serve as a record of the building or infrastructure project, providing vital documentation that can be used for future reference. These documents help facilities managers, engineers, architects, and contractors to analyze past construction activities and identify areas of potential improvement for future projects.
What Information Do As Built Drawings Typically Contain?
As built drawings must be comprehensive and detailed and contain all the necessary information for future use. The scope and level of information contained in as built drawings often varies by project, building types, and design specifications. Typically, this kind of drawing will include:
- – Original design specifications and the difference between them and the actual construction (changes, additions, deviations).
- – Structural systems, including foundations, walls, beams, and columns.
- – Electrical systems, such as power layouts, distribution boards, and control panels.
- – Plumbing systems, including piping diagrams, valves, and fixtures.
- – HVAC systems, such as heating, cooling, and ventilation.
- – Fire protection systems, including fire alarms, sprinklers, and extinguishers.
- – Finishing details, such as flooring, painting, and ceilings.
- – Site details, such as landscaping, pavement, curbs, and fencing.
In Conclusion
As built drawings represent the final construction drawings that capture all the adjustments and modifications made during the construction process. These drawings are essential for future maintenance, renovation, and modification and serve as a record of the project. Inaccurate or incomplete as built drawings can create unnecessary challenges for the future maintenance and related activities, leading to increased expenses and delays. Therefore, it is incredibly important to ensure that as built drawings are comprehensive, detailed, and accurately reflect what has been built.

How As Built Drawings are Created
As built drawings are an essential part of the construction industry, which assist the project team with verifying that the final construction of a project adheres to the original specifications. The process of creating as built drawings starts with the review of the original design and construction drawings that were produced before the construction project began.
The as built drawing process aims to capture all changes that have been made during the construction phase. Regular site visits are made to inspect progress, identify changes and record details with status updates on construction progress. This process is accomplished through detailed site notes, and annotations performed on the original design drawings or a digital 3D model of the design in the case of a BIM project.
The as built drawing, produced following completion of a construction project, captures changes and ensures that any modifications made are correctly and accurately updated in the documentation during the construction phase. The initial design plan may indeed include any future modifications made at a later stage of construction.
To produce comprehensive as built drawings, the project team might also collect photos, test reports, surveys, and other relevant documents, such as product data from suppliers, drawings from sub-contractors, inspection records, and certification documents. The as built drawing should always be considered a live document, constantly progressing. Without the creation of as built drawings, any subsequent changes will be hard to document and might result in a situation that is difficult to manage for the project team, which highlights the importance of this process.
The purpose of as built drawings is to serve as the final set of drawings, which accurately represents the current state of the construction project. These drawings may be used extensively by construction professionals for maintenance, repairs, future modifications, and even during future next construction phases.
Overall, as built drawings are vital for assessing the accuracy of the construction design based on the final constructed result. The process of creating as built drawings is not merely a matter of copying existing drawings, but also one of ensuring that the construction project is completed accurately according to the original intention and to the benefit of all parties involved. Construction industry professionals need to have the necessary skills, knowledge and tools to generate accurate as built drawings throughout the construction process.
The Benefits of Using As Built Drawings
As built drawings refer to the final set of drawings which reflect any changes, modifications or alterations carried out during the construction process. Using accurate and up-to-date as built drawings can bring several benefits to any construction project. Let’s explore some of the most essential advantages:
