With a complete re-engineering, Revizto has realized a BIM vision and dream, bringing it to life now, not in the next 5-10 years. Everyone wins with Revizto!" - Jason Howden, Principal | Digital Innovation Leader, Warren and Mahoney "Extremely cool, something we have been waiting for a while now and can hopefully allow our field crews to readily adapt to the new age workflow." - Tanner Scholin, BIM Detailer, Murphy "Revolutionary app that will help push construction into the 21st century. A surprisingly quick way to view models from your phone!" - Jeff Kocinski, Associate/ Project Architect, SCB "I used the app for 5 minutes and definitely left thinking it would lead to more adoption in the field by our internal project teams as well as the subcontractors. Being able to fly the model with how light/easy it was, while going through issues in both 2D and 3D will definitely help." - Shaun Carollo, VDC Manager, Hoar Construction ______________________________ Don't have an account yet or want to learn more?
