PDF Reviews Are Broken in Engineering
Current workflows create delays, miscommunication, and frustrated teams.
Email Chain Hell
Markups get lost in email threads. Version control becomes impossible. Critical feedback falls through the cracks.
Desktop-Only Tools
Field teams can't mark up drawings on tablets. Site visits require printed plans. Mobile reviews are impossible.
Expensive Licensing
$300+/user/year for BlueBeam, even for reviewers who barely use it. Budget-breaking for large project teams.

Case Study: Metro Transit Authority
How Goldline reduced review cycles from 3 weeks to 3 days
The Challenge
Metro Transit was spending 3+ weeks on each round of structural drawing reviews for their new rail extension. Field engineers couldn't mark up drawings during site visits, causing delays and miscommunication between office and field teams.
The Solution
Deployed Goldline for the 50-person project team. Field engineers now mark up foundation plans on tablets during daily site visits. Office team sees updates in real-time.
"Goldline transformed our workflow. What used to take 3 weeks now takes 3 days. Our field teams love being able to mark up drawings on their tablets during inspections."
