Redline™ Planroom

Planned Productivity.

Discover plan-centric project management with the revolutionary Redline Planroom. Upload plans, make notations and markups, and pin tasks directly to your sheets.

Give your projects clarity with markups, notes, photos and more.

Redline™ Planroom makes it easy to add markup, progress photos, notes and more, so everyone on the job knows what's changed and where work needs to happen. Cut down on confusion and increase productivity on the job site with intuitive drawing, text, and shape tools. Your team will automatically see the latest updates to the plan set, so nothing falls through to cracks.

Pin project tasks, variations, RFIs and more directly to your sheets.

Manage your jobs with maximum efficiency and clarity by pinning tasks, variations, RFIs, punch lists and more to your sheets. You can assign items to your team so they'll know exactly where on site they need to be and what needs to be completed. You can also review observations made in the field, so you'll stay up-to-date and in the loop.

Save hours of data entry with automated sheet scanning and hyperlinking.

When you upload your plans, our proprietary UDAi™ machine learning technology scans your plan set and automatically detects sheet numbers and names, so what used to take hours is done in minutes. Our system will also find any callouts and automatically link them to the correct detail of index sheets, so finding what you're looking for is a cinch.

The current set ensures your team is working from the latest revisions.

Working from outdated plans can turn into an expensive, time-consuming headache. When you upload revised plan sets to your jobs, Redline's automatic sheet versioning creates new revisions, labels them, and places them in the proper order in the current set view.


Show, Don't Tell.

Miscommunication is a thing of the past with the SmartShot™ Visual Reference report, generated directly from Redline Planroom. The report includes any pinned items and markup, so you can show team members exactly where work needs to happen, along with descriptions, due dates, cost impacts and more.
