5 Best Redline Drawing and As-Built Software

Cloud-based software has streamlined the once-tedious as-built creation process, making it easy for teams to document what is actually being built as it’s being constructed. 

Looking to up your as-builting game? Find tips in our guide to digital as-builts.

But with many construction software products offering a range of capabilities, it can be hard to choose a product with the features necessary to redline drawings and create accurate, high-quality as-builts. 

So we’ve done some research for you and have reviewed top redline drawing and as-built software offerings that can make your documentation a breeze. Before we dive into those reviews, it’s important to understand some key terms and traits in order to select the right software for your project.

As-Built vs. Redline Drawing Software: Understanding the Difference

You’ve probably heard the terms “as-built” and “redline” used interchangeably. But they are two different concepts, and knowing what each is will help you better understand the capabilities and strengths of different software.

“Redlining” refers to the act of marking up drawings to reflect the changes made to the original design as construction takes place.

“As-builts” are the drawings that include all the redlines from different sources throughout the construction process. At the end of a project, they are packaged with additional project documentation and turned over to the owner as a record of exactly what was constructed and where everything is located.

Project managers at a jobsite use redline drawing software on a mobile device.

Why the difference matters in evaluating software

“Redlining” capabilities generally refer to the tools that make revisions to drawings – which in a digital space includes not just marks and comments drawn on plans but attachment of other file types (photos, video, and project documents).

“As-built” centers more on the process and “record” aspect of the software – having all documentation up-to-date, accurate, organized, searchable, and ready to be exported for the owner at project close.

Most software in this space – certainly those reviewed in this blog – have both redlining and as-builting capabilities, but they may be stronger in one area over another. So it’s important to think about what functionality you require in your day-to-day work and to look closely at the traits of different software so you can select one that best meets your needs.

7 Key Traits to Look For in As-Built & Redline Software

High-quality as-builts are accurate, comprehensive, and capture and share data in real-time. To redline drawings effectively and create as-builts with these qualities, you'll want software with the following traits:

1. Mobility

It’s critical to be able to mark up plans and document work from the jobsite. When data is captured and shared straight from the construction site, you avoid a game of telephone and ensure your data’s accuracy.

Field-friendly apps mean that workers can gather data and revise plans to reflect what they are building and finding on site in real time. Additionally, they can share updated project information immediately, so everyone on the team is always on the same page. Software with offline mode ensures that they can still capture important information even when internet connection is spotty or nonexistent. 

2. Markup tools

Easy-to-use markup tools make it possible to revise plans and documentation directly so that no manual transfers of data are necessary – cutting down on the likelihood of transcription errors or information lost in the shuffle. Options to select colors, opacity, shapes, and line or border styles (dashed, dotted, double, etc.) enable customization.

3. Multimedia data capture

The ability to add photos, video, and comments to drawings at the specific locations they relate to provides vital context and streamlines communication. Visual documentation of your project also makes for a more accurate as-built.

For many redline drawing and as-built software, multimedia often falls under the umbrella of markup tools. 

4. Ease of versioning

One of the biggest challenges of as-built creation – and project documentation in general – is making sure everyone is working from the most up-to-date information.

Software with the capability to automatically slip-sheet updated pages into plan sets and/or notify users when the drawing they’re looking at is not the latest version can alleviate headaches in drawing management.

5. Ease of use

Ideally, you want software that’s simple to learn and use. Complicated interfaces and confusing workflows will hurt adoption – workers in the field can’t afford to stop in the middle of tasks that require their full attention to fool with tricky field apps. 

6. Cloud-based collaboration

As-built creation is a team effort that relies on dispersed workers updating documentation across the jobsite or even from remote offices.

Cloud-based software provides a centralized place to share, store, and view drawings and documentation. It also enables real-time communication and collaboration between the office and the field – which streamlines workflows and saves time and money.

7. Map-based

When drawings are geolocated, stakeholders can see where work – and any related issues – are happening, not just in the context of the plan but in relation to the real world.

And by recording the actual location of an asset – and providing location data through the entire project record – the final as-built delivers higher value for owners and their operations and maintenance activities.

How to Use Software to Redline Drawings and Create As-Builts

Once you’ve selected your software, you can streamline your redline and as-builting process. Here are the day-to-day steps you’ll follow to document as-built information in sync with construction.

1. Upload plans

The first step is simple: upload your plans. If your plan is not already in PDF format, you’ll likely need to convert it. Bluebeam has several plug-ins for creating PDFs of CAD files from a few other softwares. Otherwise, it’s fairly easy to find converters online.

If you’re working with paper drawings, you’ll need to scan them and save them as PDFs, which can then be imported into your as-built and redlining software.

2. Mark up your drawings

Did you stumble upon undocumented utilities in the field? Needed to change the location of electric infrastructure? Use your software’s markup tools to redline construction drawings to accurately show as-built conditions.

Make traditional redline drawing changes with freeform lines, shapes, and text in colors of your choice to show additions and deletions to your plans. And take advantage of tools that enable you to pin additional file types to your drawings – photos, videos, and documents such as RFIs, change orders, and submittals.

With this change documentation attached to your drawings, you can create a richer project record, where all the information you need is easier to find.

3. Collaborate with team members

Using cloud-based software ensures that redlines from the field and changes originating from the office are shared to the team in real time. Stakeholders can access dynamic data that is continually updated, so they are always working from the most current drawing version and information.

With the cloud, there’s no need to manually transfer data – exporting static information (like a PDF) then sharing via email. While there is a place for that method of data sharing, the cloud helps you avoid the risk of errors or siloes that can arise with exporting and emailing files.

Construction workers use as-built software on a tablet to check for their task assignments.

4. Track progress and assign work

A benefit of your team using cloud-based software to document what is being built is that you’ll have visibility into the real-time status and condition of your project at any given time.

That valuable stream of information will help to inform smart decision-making, and you can then use your software to communicate next steps with your team. Assign tasks and connect them to drawings, so assignees can quickly see exactly what work needs to be done where – even easily navigating to the correct work location when the task is pinned to a geolocated plan.

When they have completed their task, they can note it – and include photo documentation – in the same assignment, providing a complete record of work for the as-built.

5. Export your as-built

When the project wraps up, it’ll be time to deliver your as-built. Because changes have been documented and stored continuously, your software should be able to package all the information needed and export it with just a few clicks.

You’ll generally have a few options for the file type you want to export. For example, in OnePlace, you can export as-built documentation as GIS information in Shapefile, GeoJSON, or KML format. So be sure to find out what format the project owner would prefer.

Follow these steps and you’ll be using your software effectively to redline drawings and create high-quality as-builts.
