Blueprints are set of proposed drawings and elevations produced at the time of construction or refurbishment of a building. These drawings were commonly used for over a century for the reproduction of specification drawings in construction and industry.
However, there’s one big problem: in the majority of cases, blueprint drawings do not match what was actually built. Changes to the design often go unrecorded, making things much more complicated further down the line.
For this reason, blueprints are no longer recommended when creating a new design proposal due to their questionable precision.
As-built drawings are the final set of drawings produced at the completion stage of a construction project. They show the dimensions, geometry, and location of all components of the project.
This is much easier to accomplish with detailed notes recorded throughout the construction phase, including information about any changes to the original plan.
3D laser-scanning technology can be used for as-built drawings to record any changes along the way and make any necessary alterations after the drawings have been produced. These 3D models can then be translated into highly accurate 2D as-built drawings. To find out more about how this works, go to our 3d laser scan to 2d plans page.
How to Create As-Built Plans
As-built drawings should be reviewed and inspected regularly to ensure accuracy. It’s crucial to record the exact details of changes or additions to previous information as soon as they happen. Some examples of this are different sizing, materials used, dimension measurements, or installation.
Remember to add dates to the sheets so that you have a clear record of the whole process, and use colours to code any details that have been changed, added or deleted.
3d Laser Scanning for As-Built Plans
3D laser scanning is a great choice for as-built plans, as it provides the accuracy needed for construction planning and can compare newly built work against the original drawings. It’s ideal for planners, designers and engineers, who benefit from real as-built drawings with the assistance of 3D laser technology.
One of its most useful features is its clash detection function, which will immediately report any inconsistencies so that they can be reviewed and updated ahead of time.

3D laser scanning is used by the majority of contractors, designers and architects. Here are just a few of its key benefits:
- It detects clashes or inconsistencies early on in the process to prevent any unforeseen problems, making it more cost and time-effective in the long run.
- Using precise data reduces the need to alter plans due to drawing misrepresentations.
- 3D laser scanning creates a digital copy of the plan, which is much easier to transfer and communicate (both with the team and with clients) than hard copies of blueprint drawings. Data is more secure and consistent, and can be shared easily.
