What Is an “As-Built?” – Also known as record drawings and red-line drawings, as-builts drawings are documents that allow a compare and contrast between the designed versus final specifications, and provide a detailed blueprint of the building and the land around it as actually constructed in the end.
- Field changes
- Shop drawing changes
- Design changes
- Extra works
As-built drawings go hand-in-hand with as-built surveys, also called as-built maps. These are used during the construction phase to continually track how the land and building is changing as work progresses. Dedicated as-built surveys make as-built drawings much easier to construct in the end, because of the greater level of detail recorded from every stage of the project.

What is the difference between as drawn and as-built drawings?
Back to the Basics: Shop Drawings and As-Built Drawings – If you belong to the AEC industry, you must have heard about Shop Drawings and As-built drawings, The designing stage of any construction project is essential for its satisfactory execution. Every type of construction drawing has its own purpose and a set of features. Every building comprises a set of components. All of these components have distinct specifications and measurements. Shop drawings are the detailed versions of these components and help identify how they will fit into the building structure, More importantly, the shop drawings are made before the start of a construction project,
Personify the true imagery of the construction project. These drawings need the consent and approval of the construction team Needed for coordination within the construction team. Once approved, the shop drawings are referred to the most number of times while the construction of the project is underway.
This means that the contractors, builders, workers, and supervisors will have the details of all the components beforehand. They are like the original version of the building design and how it has been imagined by the contractors or the subcontractors,
- However, there is a thin line difference between the construction drawings and shop drawings.
- Where the shop drawings depict the original design of the building, the construction drawings are modified from time to time.
- They include the revisions a building has undergone whilst the construction process is underway.
The shop drawings are not limited to the outer structure of the building, They include all the MEP components, fabrication and other types of detailing, Even the doors and window installation schematics come under the purview of shop drawings. Added to this, the shop drawings are also helpful in identifying what kind of materials will be needed for the construction process.
- And once your shop drawings are ready, you won’t have to waste time and resources on explaining the whole process to your team.
- These drawings are self-explanatory and the contractors will understand the dimensions, materials to be used, timelines, installation process and everything else.
- So, it is essential that your shop drawings must be ready before the beginning of the construction process.

It can be said that the as-built drawings are needed to compare what was originally planned and what has been made in the end,
Issued to the client after the project is complete Includes everything from the structure to the installations and their details. Important from the perspective of the client and allows them to analyze the end product.
There are a lot of benefits to making the as-built drawings. They help in the installation of the emergency services in a building, Apart from this, the as-built drawings are essential for conducting any repair or refurbishment works in the building, Well, both types of drawings are made by subcontractors and contractors. So, there is no difference in this aspect. The as-built drawings are made after the completion of the project. And the shop drawings are made before a construction project starts. As-built drawings can be made for the whole building as well as for specific components.
But the shop drawings are only made for the different components of a building. Both types of drawings are not a part of the contract documents. They can be or cannot be included in the contract. So, it is not essential to always add these drawings to the submission documents. Only the shop drawings can be changed as they are yet in the pre-development stage.
The as-built drawings, on the other hand, cannot be changed as the building has already been constructed. However, they can be changed during the renovation works. Well, both types of drawings are made for all kinds of projects. But the as-built drawings are particularly more important commercial and high-scale projects.
What is the difference between as built and as designed?
As-Designed or As-Planned Data – As-designed data or as-planned data is the engineering plan to which product should be built. These are the drawings, test plans, and build procedures that should be used when the product is assembled. As-designed data includes the planned product structure such as the parent part revision and part revisions of all child parts.
- As-designed data also includes engineering change orders and the planned revision letter or date when those engineering changes are made on the production line.
- As designed data is managed using Product Data Management (PDM) tools.
- Some of the most commonly used PDM tools are PTC’s Windchill, Epicor PDM software, SolidWorks Enterprise PDM, Siemens PLM’s NX CAD software, and PDXpert PLM.
As-designed data describes the parts list at a particular time, while as-built data records the part revisions of what was assembled. David Wilhite, author’s husband, from his master’s thesis on Stewart Platforms
How do you make as-built drawings?
What’s the Difference Between “As Built” and “Record” Drawings? – Often, the terms “as built drawings” and “record drawings” are used interchangeably, but there are important differences between these two documents, As explained above, as built drawings are generally created by a contractor during construction, with color coded notes written directly on top of the original plans.
Who prepares the as-built plan?
‘As-Built’ plans shall be submitted by the contractor within 30 days upon reaching 95% completion of the project.10. No Certificate of Completion shall be issued to the contractor unless the ‘As-Built’ plan has been approved.
What do as-built plans look like?
What Subcontractors Need to Know About As-Built Drawings – While subcontractors aren’t generally directly involved in creating as-built drawings, they must keep detailed notes about any changes to materials or specifications during their work, so they can be incorporated into the drawings.
When making a change to the original design or specifications, you must record the exact changes, including sizing, dimensions, materials used, and installation notes. To ensure your notes are clearly communicated, avoid using abbreviations, and follow any pre-established color coding (e.g., red for deleted items, green for additions, and blue for other changes).
Changes during the construction process are inevitable — but collaborating closely with the general contractor, architect, and crew to create accurate as-built drawings will ensure that the full scope of your work is captured and recorded.
How accurate are as-built drawings?
4 min read – A single factor can make a massive difference in your construction projects: As-Built drawings. From planning to execution, these drawings — when accurate — provide the type of starting point that will create confidence in your final product, adding value to your projects and reducing unnecessary risk for your team.
With accurate drawings of your building, you can make smart decisions on site. Whether you’re an architect, designer, construction manager, or any other part of the real estate development process, you can feel assured that you are making smart decisions based on situational awareness of the space you’re improving.
As Built drawings can serve as one of your biggest assets. The quality of set of As Built drawings relies on its accuracy. The documents must not only reflect any changes realized throughout the building process, but needs to fully represent what now exists as a result.
Creating these drawings can be costly and time-consuming without the right technology and help from experts. “As Built’s” are a highly detailed set of measured drawings of a building in question. Size, shape, dimensions, and locations all elements of the built environment factor into the accuracy of an As Built drawing.
Accurate As Built’s serve as an accurate point of departure for all the project’s stakeholders. Final As Built drawings will incorporate modifications, field changes, design changes, and any alterations that occurred in the construction process. They can even offer a compare-and-contrast view between the designed building and the final blueprint.
As a result, As Built’s have a number of important uses, like helping architects or construction managers understand the step-by-step evolution of their work. Post-construction, facilities teams who manage the building can solve issues faster. Planning and renovation require less upfront expense, since everyone “is working from the same sheet of music.” Knowing the exact dimensions and characteristics of a space is a “must-have” in any construction or development project.
Without an accurate starting point, it’s nearly impossible for teams to effectively manage the uncertainties that come with construction. Consider an existing structure with four walls. While it may seem easy enough to measure manually with a tape measure, that approach results in a small, but meaningful, margin of error.
If one were to apply that approach not just to a room but to an entire building, the results would be unacceptable. However, with 3D laser scanning, the measurement process is not only much faster, but it’s also exact with virtually no human error. You can start accurate and stay accurate. Instead of using hand-measured drawings, today’s best As Built’s benefit from the ability to generate millions of measurements per second in three-dimensional space using 3D laser scanning.
Thanks to modern laser-based and digital technology, it’s easier than ever to ensure that:
The drawings are created with digital measurement, eliminating human error and promoting accuracy As Built drawings are available and accessible to any stakeholder who might need them The drawings are easy to access from anywhere, including job sites, by utilizing the cloud Each As Built is a living documents that can be updated as needed
For the architects and designers who are often tasked with creating these As Built drawings, using the right technology is essential for accuracy. It’s also smarter in the long term: it’s economical, and it ensures your reputation as an accurate, data-driven business with high standards, driving more business.
When contractors are given a dependable set of As Built’s, they can provide more accurate pricing, cut costs thanks to fewer mistakes, and waste fewer materials. Unfortunately, today’s As Builts often have missing or inaccurate information. That leads to errors that slow down the building process and reflect poorly on you.
These types of drawings might:
Lack three-dimensional information Fail to include photographic documentation Only have surface-level data Be difficult to update Be disorganized
The first step is to set yourself up for success right at the beginning, by determining your needs, choosing your technology, and committing to keeping As Builts updated through the entire construction process. Using the cloud for data capture, storage, editing and distribution is a great way to ensure these details don’t fall through the cracks.
Having phones or tablets on site helps with photos and notes, which will be essential to the accuracy of your project. Once you have established the importance of your As Built drawings, and have the information in place, it’s important to understand that there are many options for capturing data.3D laser scanning data can be used for Building Information Modeling (BIM), which shows multiple physical and functional characteristics of a property.
This format has several important uses. BIM documentation can be used for creating virtual walk-throughs, increasing work site safety and productivity, improved scheduling and sequencing, model-based cost estimation, clash detection, and accurate square footage calculations.
Do as-built drawings need to be stamped?
As-Built plans may be used as reference or the basis of plan sheets for future projects. Each sheet of the As-Built plans must be clearly identified with an As-Built stamp (except NSPs or RSPs).
Why is as-built important?
What is an As-Built, and Why is it Important? ACD recently led a project that improved the water quality benefits provided by two stormwater ponds adjacent to Martin Lake in Linwood Township. The project increased the size and depth of the ponds to the maximum extent practicable within the limited spaces available.
The projects were a great success, and were recently highlighted in an outreach article titled, ”. They’re worth mentioning again in order to highlight a critical piece of successful construction management that most people never see, the as-built survey. As-built surveys, also commonly referred to as record drawings, provide formal documentation of exactly how a project was installed.
They document the actual results of the construction project rather than the planned layout shown in the project design and are critical for project closeout. As-built surveys ensure the project was built to meet the specifications in the original plan set.
- This allows the project engineer to confidently sign-off that the project was installed as per the plan.
- If any deviations from the original plan were approved during the construction process, the as-built survey will show the changes as they were installed and provide an opportunity to formally document those changes.
Final payment to the contractor is also typically withheld until engineer sign-off on the as-built survey. The as-built survey also provides a formal record that can be used to standardize how a project should be maintained over its lifespan. In the event of these stormwater ponds, accumulated sediment and debris should be periodically removed to achieve the original design depths in order to ensure the ponds continue to function at maximum efficacy.
Depending on the type and scale of a project, multiple as-built surveys may be completed throughout the construction process to confirm critical elevations and layouts are being met prior to approving advancement to the next construction step. They are typically shown as an overlay on the original plan sheet to allow a direct comparison and easy identification of any significant deviations from the original plan.
The 228 th Place stormwater pond as-built (see plan sheet below) documented key elevations around the pond to ensure safe side slopes were achieved. It also documented the stabilized outlet and controlled overflow elevation to ensure neighboring properties were not at risk of flooding as a result of the project.

Can I do my own drawings for planning?
How to get planning permission without an architect? – You don’t need an architect to obtain planning permission, You can submit your plans yourself online via your local authority’s website or in person. Having an architect submit your plans will not guarantee they are approved.
- If you know, for example, that your planned rear extension, is a replica of works next door that was approved last year, then it is likely your plans will also be approved.
- You can request a pre-application meeting with your planning department before submitting plans.
- It comes at a cost but may be valuable in understanding any possible issues with your plans.
You can then rectify any issues before paying to formally submit plans. This meeting and a little research should help you determine local planning restrictions, targets and preferences. So, you can tailor your project accordingly. If you aren’t confident doing this yourself, a good planning consultant might be an option to help you through this process.
