For the last two years, Y Combinator alum PlanGrid has helped modernize the construction industry by moving blueprints to tablets. After originally launching on the iPad, the company will now offer all the same features and capabilities on a wide variety of Android tablets.

At the end of the day, PlanGrid’s mobile app enables construction teams to cut paper out of their blueprint plans. Instead of printing out new versions of a blueprint every time it gets updated and sending them out to all the people on site, images can be uploaded and then viewed on tablets.

By moving blueprints off paper and onto tablets, PlanGrid helps to save construction teams a ton of money. But it also enables PlanGrid users to more efficiently use the blueprints they have, and more quickly update or make changes to them.

Last summer it added hyperlinking between plans stored on the app. Users can also mark up blueprints and quickly share changes or annotations with others.

Since launch, the company has been used on more than 125,000 construction projects, and more than 20,000 blueprints are uploaded every day to its network.
