The Difference Between As-Built Surveys and As-Built Drawings: Why Both Matter in Construction

When a construction project wraps up, the structure standing on the site often looks a little different from the original design plans. Whether it’s small changes to the layout or significant adjustments due to unforeseen site conditions, these modifications need to be captured accurately. That’s where as-built surveys and as-built drawings come in. But what exactly are they, and how do they differ?

What Are As-Built Surveys?

An as-built survey is a detailed field survey conducted after construction is complete. It documents the exact locations, dimensions, and features of the completed structure. The survey provides a snapshot of what exists on-site—giving a real-world view of the finished project, as opposed to what was initially planned.

The survey typically covers:

  • The structure's actual location
  • Utilities, roads, and other external elements
  • Elevations and dimensions that might differ from original designs
  • Any deviations made during construction

These surveys are especially useful when planning future renovations, expansions, or even for legal documentation purposes.

What Are As-Built Drawings?

As-built drawings (sometimes called "record drawings") are the blueprints or plans that reflect all the changes made during the construction process. While they begin as standard construction drawings, updates are made throughout the project to show every modification, from material changes to layout tweaks.

The main difference here is that as-built drawings don’t require a physical survey like as-built surveys. Instead, they are created based on information from contractors, engineers, or architects who document changes as the project progresses. They act as a paper trail of adjustments, ensuring everyone involved knows exactly what has been built.

Key Differences Between As-Built Surveys and As-Built Drawings

While as-built surveys and as-built drawings often serve a similar purpose—documenting the final state of a project—they approach this goal from different angles:

Challenges and Best Practices for Creating As-Built Drawings

Keeping as-built drawings accurate throughout a project can be challenging, particularly if updates are delayed or not logged in real-time. Without consistent updates, teams may find themselves scrambling at the end of the project to remember and document all the changes made on-site.

To avoid this issue, a best practice is to establish a process where updates to as-built drawings are captured as they happen. This could involve assigning specific team members the task of logging changes immediately or using digital tools to streamline the process. Regular updates ensure that no detail is missed and that the final drawings reflect the true state of the project.

Technology and Tools for Managing As-Built Records

As-built surveys and drawings are becoming easier to manage thanks to modern technology. Cloud-based platforms and mobile apps now allow construction teams to update and share as-built records in real time. For example, using mobile devices on-site, contractors can immediately input changes into digital drawings, ensuring the entire team has access to the most current plans.

Additionally, software solutions like KYRO, Plangrid, and more, offer integrations with field tools, allowing teams to sync field measurements directly into digital models or drawings. These tools not only improve accuracy but also save time by reducing the need for manual updates.

Importance of Coordination Between Teams

Effective communication between contractors, architects, engineers, and surveyors is essential for accurate as-built records. Without clear coordination, changes made in the field may not be captured in the drawings or surveys, leading to discrepancies that can cause confusion or costly rework down the line.

One way to improve coordination is by using collaborative platforms that allow teams to share updates in real time. For example, if a contractor makes a layout change on-site, that information should be instantly shared with the design team to ensure that as-built drawings reflect the new configuration. Clear communication ensures that the final records are comprehensive and accurate.

How They Work Together

In many cases, as-built surveys and as-built drawings work hand in hand. While drawings document what was planned and then changed during construction, surveys confirm what’s actually in place after completion. Having both on record ensures a comprehensive understanding of the project, helping teams plan for future work or resolve any disputes.

Why Accurate As-Built Records Are Essential

Whether it’s through as-built surveys or drawings, keeping accurate records of a construction project is crucial. These documents protect against future confusion, help maintain compliance, and provide a solid foundation for future projects. Plus, with today’s digital tools, keeping these records organized and accessible has never been easier.

If you’re planning a project or managing a build, don’t overlook the importance of maintaining updated as-built records. In the long run, they save time, reduce risk, and help keep projects running smoothly.
