As-Built Drawings, Record Drawings and Measured Drawings: What’s the Difference
The designing stage of any construction project is vital for successful execution. And, each type of drawing for this purpose has its unique purpose and certain features associated with it. This offers a detailed overview of different phases of a project, from the design process to permitting the actual building process. Ranging from the foundation to making models, these drawings provide an outlet for the architectures to transfer their ideas and concepts in reference to any building.
If you belong to the Architecture, Engineering and Construction (AEC) industry, then there’s a likelihood that you heard about record drawings, as-built drawings and measured drawings. These terms are often confusing and used interchangeably, but they are different.
Let’s understand the basics and the difference between these three important drawings. This article will help you understand the specifics of each and what sets them apart.
As-built Drawings
Definition
Documents that help identify changes made throughout the entire course of construction projects. They reflect each change the structure has undergone. It includes major as well as minor modifications made in the specifications such as design changes, show drawing changes, component relocation, and more. As-built drawing helps depict the difference between pre-and post-development.
Preparation Procedure
As-built drawings are made either during the construction process or after the final construction of the project. Contractors create it by utilizing field data collected during the project. It becomes quite easy when they keep detailed track of all the changes including every phase of the construction process such as show drawing changes, design changes, component relocation and more.
Benefits
- Better building maintenance
- Provides a detailed record of improvements made during the construction process
- As-built drawing standards relate to health & safety
- Provides an accurate view for future work and demolition
Record Drawings
Definition
It is a final compiled drawing that marks the notes of the on-site measurements changes that the contractor makes in the as-built drawings.
Preparation Procedure
Record drawings are usually drawn and compiled as an “architect approved” set of on-site changes made exclusively for the owner as per the architect-owner contract. It is more reliable than as-built drawings
Benefits
Indicate all features of the development as it has actually been built.
Measured Drawings
Definition
They are prepared from on-site measurements of the already existing building or space.
Preparation Procedure
These drawings and measurements are prepared from on-site project data.
Benefits
Measured drawings are based on new projects on existing buildings.
Final Thought
To conclude, the comparison of as-built vs. record drawings vs. measured drawings doesn’t always require choosing one over the other. If you’re looking for as-built CAD drawings and documentation services, you can consider outsourcing an experienced engineering company.
