GAMMA AR: Augmented Reality for Construction Site Management GAMMA AR is an application designed for monitoring construction sites. It utilizes augmented reality technology to overlay 3D Building Information Models (BIM) on construction sites using smartphones or tablets. With GAMMA AR, site managers, facility managers, craftsmen, and other stakeholders involved in the construction process can walk through the site and compare real-world conditions with the planning information contained in 3D BIM models. GAMMA AR enables the visualization of 3D BIM models before and during the construction process, thereby fostering a better understanding of the planning, preventing errors, and reducing construction costs. This enables site managers and planners from various disciplines (HLS, architecture, etc.) to collaborate on the construction site using the BIM model, preventing collisions and resolving ambiguities before they lead to errors. Additionally, GAMMA AR allows for the direct detection of errors within the BIM model, enabling adjustments to be made during the planning phase, preventing errors, and ensuring comprehensive monitoring of construction progress. Is GAMMA AR for you? GAMMA AR allows you to connect various software systems such as Autodesk, Procore, and BIMCollab. Construction site managers benefit from GAMMA AR by avoiding errors and eliminating the need to interpret 2D plans. Facility managers can report errors or make adjustments directly in the BIM model via GAMMA AR and transmit this information to other stakeholders involved in the construction process. GAMMA AR is an easy-to-use, intuitive tool that can be applied directly without requiring any training that could increase the cost of implementation. For construction companies, GAMMA AR offers significant benefits: entire departments can be relieved of the burden of communicating via 2D plans, which is no longer necessary. GAMMA AR establishes digital communication channels between the construction site and the office. Using BIM360 or Autodesk Construction Cloud (ACC)? Simply sign in with your Autodesk account, import your IFC, REVIT, and NAVISWORKS models into GAMMA AR, and synchronize your issues with BIM360, ACC, Procore, or BIMCollab. Summary Avoid Errors: Plans on-site are cumbersome and prone to errors! For many tasks, it is faster and safer to review the plans directly on a tablet and compare them with real-world conditions. By working digitally on tablets and smartphones, the reliance on paper plans is significantly reduced, thereby lowering the risk of obsolete information and redundancies. Sync Models and Notes with Your Office: With GAMMA AR, you can send issues directly from the construction site to the office. Each comment is directly linked to a building element or room during site inspections. With this location reference, new information is immediately integrated into the building model. This simplifies documentation and improves communication, as comments are clearly and unambiguously conveyed. ## Key features - Augmented reality BIM overlay - On-site construction monitoring - Error detection and prevention - Digital communication channels - Integration with Autodesk, Procore, BIMCollab - BIM model synchronization ## Recent user reviews (7 of 7) All indexed reviews: https://appshunter.io/ios/app/gamma-ar/id1298017298/reviews.md ### 5/5 — Perfekt für 3D Abgleich *2023-11-22, version 5.0.3* Wunderbare Software und sehr schnelles, agiles Entwicklungsteam! Es gibt keine bessere AR Bausoftware auf dem Markt. ### 5/5 — Bridging the gap between BIM and on-site *2023-04-28* Great app for all user, beginners and experts. Close the gap between BIM and the install team. ### 4/5 — Good app *2019-07-10* The app is very simple to use and a great visualization tool, there are some things that could be done a little better but overall really great app. ### 5/5 — Great app *2019-06-05, version 1.3.1* This application really helped me alot great work keep it up ### 5/5 — Einfach Unglaublich *2019-06-05, version 1.3.1* Die App ist super!!! Kaum Bugs und einfach Bedienbar. Sehr empfehlenswert. 👍🏼 ### 5/5 — Very helpful for onsite comparison *2018-09-22, version 1.2* Great tool to overlay reality with digital plans (supports IFC as the central open Bim format) ### 3/5 — I don’t have a business well out of luck *2018-06-21* I really wanted to use this app but then I got in and was about to create a account and saw you had to put the name of your business. I don’t have a business I was just looking for something to help me finish off the inside of my greenhouse. But because I don’t have a business I’m out of luck I guess. ## Frequently asked questions about GAMMA AR ### What is GAMMA AR used for?
