A joined up way of working for construction

Used BaseStone for 8 months on major public infrastructure project.
Finally a joined up way of working for the construction industry to emerge from the dark ages. Easy to use but powerful and effective project management collaboration tool. In addition to managing site issues and site change control has been successfully used for tracking and managing installation status for equipment as part of testing & commissioning process. It’s not perfect (what is) but BaseStone have listened to us a customer and have provided great customer support. It’s still evolving and being developed (but that’s good). Thoroughly recommended.

Great construction site app

I’ve been using the app for a few months and am very pleased with it. The app allows you to access your engineering drawings and mark them up on site. This can be used for setting out, raising issues and redlines. Highly recommend!

Fantastic App for Architecture and Construction

My go to app for drawing issue, snagging and site reports. It's amazing to have all all a project's documents in one place and accessible on the move. Great to be able to view a project's entire issue history. Time saving & convenient. Invaluable!
