Key Highlights
As-built and record drawings are essential for accurate documentation of a building project.
As-built drawings reflect the actual construction, including any on-site changes made.
Record drawings are the architect-approved versions of as-built drawings.
While contractors typically handle as-built drawings, architects maintain record drawings.
These drawings are important for future renovations, legal purposes, and facility management.
Understanding the differences can prevent confusion and potential liabilities.
Introduction to The Difference Between As-Built Drawings and Record Drawings
In the detailed world of construction, the design team’s ideas become real through careful work. Accurate documents are very important. As-built and record drawings are key to showing the final design and the changes made during the construction process.
This guide will help explain the main differences between these two important types of documents.
Understanding As-Built Drawings
As-built drawings, also called "as-constructed" drawings, show an accurate view of a project after it has been built. They carefully record every change made to the original design during the construction process. These changes are marked in red ink on the construction drawings. This highlights real adjustments made because of site conditions, material availability, or other unexpected issues.
In simple terms, these drawings connect what was planned with what has been completed. They are important for any future repairs, renovations, or expansions.
Definition and Purpose of As-Built Drawings
As-built drawings are updated versions of the original construction drawings. They show all the changes made during the building. These changes are usually marked in red ink. They include new sizes, places of elements, materials used, and installations.
The main goal of these drawings is to keep a clear record of the work that was finished. This is important for a few reasons. First, they help avoid confusion in future renovation projects. Second, they make maintenance easier. Finally, if there are any disputes, as-built drawings provide a clear record of the final construction. This can be very important for legal reasons.
How As-Built Drawings Are Created and Updated
The as-built drawings are made during the construction phase. Drafting Contractors in Santa Rosa, CAÂ are responsible for changing the original construction drawings when there are updates. They often use red ink to show these changes on the drawings.
As the project moves forward, the architect or design professional will review the updated drawings. They check that the changes fit with the overall design and safety standards. This teamwork between the contractor and the design team makes sure that the final as-built drawings are correct and complete.
Exploring Record Drawings
As-built drawings show what is really happening on the site. In contrast, record drawings are approved by the architect and explain any changes. They connect the contractor's work in as-built drawings with the official project records kept by the architect.
Record drawings are often seen as more trustworthy. They get checked to make sure they follow building rules and fit the design plan. These drawings are included in the final project documents and are important for different legal and real-world uses.
The Role of Record Drawings in Construction Projects
Record drawings, also known as "as-constructed record drawings," are created after a construction project is finished. They combine details from the original construction documents with the changes noted in the as-built drawings. Unlike as-built drawings that contractors often make, record drawings are done by architects or design professionals.
These drawings are very important for several reasons. They give an accurate and legally safe record of the completed project. They are needed to get occupancy permits and for any future renovations or changes. They also act as a helpful guide for managing and maintaining the facility.
Differences Between Record and As-Built Drawings
Although "as-built" and "record" drawings are often confused, they have important differences. Knowing these differences is key for architects, contractors, and building owners. It helps to avoid confusion and issues later on.
Here are some important differences:
Authorship:Â Contractors usually create and update as-built drawings. On the other hand, design professionals, typically architects, prepare record drawings.
Purpose: As-built drawings act as a record of what was actually built. In contrast, record drawings are the official version of the project. They include changes made from the original drawings.
Liability:Â The term "as-built" can carry risks because these drawings may not meet building codes. Meanwhile, record drawings are reviewed by the design professional, which gives more legal safety.
The Difference Between As-Built, Record, and Measured Drawings
Measured drawings are an important type of construction drawing. They are often needed for existing buildings that do not have proper as-built documentation. By measuring the existing structure, these drawings help in planning renovations, additions, or just understanding the building's layout.
Here's a look at the differences between as-built, recorded, and measured drawings:
Drawing Type | Created By | Purpose |
As-built | Contractor | Lists what was actually built, including any changes from the original plans. |
Record | Architect/Design Professional | Merges original plans with approved changes to create a complete drawing set. |
Measured | Surveyor or Architect | Shows the details of an existing building based on measurements taken on-site. |
Conclusion
In conclusion, it is important to understand the differences between as-built drawings and record drawings for successful construction. As-built drawings show the real conditions, which helps with project accuracy and future upkeep.
Meanwhile, record drawings act as historical references. Knowing these differences helps manage projects better and keeps documentation correct. If you need more help or information about this topic, please contact us.

FAQ For As-Constructed Record Drawings
Why are as-built drawings important in construction projects?
As-built drawings are very important in construction projects. They act as a clear record of the work done. This is especially true for house design jobs. These drawings are key for renovations, future additions, and meetings. They help avoid problems and make sure everyone has the same correct information.
What is the difference between as-drawn and as-built drawings?
As-drawn drawings show the first design plans. As-built drawings show what was actually built. The main difference is how accurate they are. As-drawn drawings don’t include changes made during construction. They act like a blueprint. In contrast, as-built drawings show the final built conditions.
What software or tools are commonly used to create, update, and manage both types of drawings effectively?
AIA standards usually require the use of certain software tools, like AutoCAD or Revit. These tools help create and manage as-built drawings and record drawings. They are essential for handling revisions. They make sure that changes, like ductwork adjustments, are included and noted correctly. These tools also show when a project is complete.
