Video introducing CADAM3D

Welcome

CADAM3D is a user-friendly software based on the gravity method originally developed by MLT Technology for Hydro-Quebec and for Dams and Hydrology of the Quebec Ministry of Environment. CADAM3D is intensively used by Hydro-Quebec since 2005. To our knowledge, no other software similar to CADAM3D is available at this time.

If you perform stability analyzes of concrete hydraulic structures, this software will allow you to perform them much faster and more efficiently. If you are interested in this type of software and would like to try CADAM3D, please click on the "Contact" button to send us a message.

“CADAM3D is a very user-friendly dam stability analysis software. The learning period is short. The speed with which I obtain the desired results is surprising. CADAM3D is suitable for solving tangible problems. The technical service is exemplary. Excellent tool!”

Pierre Wagner, P.Eng., M.S.A. - Projects Director at Tetra Tech

“I am pleased to confirm that Mott MacDonald is using Cadam3D for his gravity dam stability analyses. It is very useful software and we appreciate the direct contact with the developer, who is listening to our requests to add functionality to the software.”

Eric Guilleminot - Technical Director, Hydropower at Mott MacDonald

“ESB have been using CADAM3D to reassess the stability of its concrete dams since July 2020. We have found the software both accurate and efficient. In addition the support offered by the developer has been prompt and knowledgeable. I would gladly recommend this software to a similar user.”

Cathal Smith - Civil Hydro Team Lead at ESB
