Nicolas Catellier / Atelier 21 Architects

Nicolas Catellier is an Architect, BIM Manager and teacher based in Quebec City, Canada. Nicolas graduated from Université de Montréal in 2011 and has been working and experimenting with BIM ever since. He started the learning website in 2016. The site provides content to help both beginners and advanced users learn Revit in a spirit of fun and simplicity. Nicolas also works for Atelier 21 architects, where he engineered the transition from AutoCAD to BIM for the entire office. He also completed projects such as the Valcartier, a 153 rooms hotel and a 70 000 square feet indoor waterpark. Nicolas acted as the lead BIM manager but also as a designer and rendering artist for the project. Bridging the gap between the technical aspect of BIM and the creative process of architecture has always been a major goal for Nicolas.

COVID-19 Update

20th May 2020

DBEI has been closely monitoring the COVID-19 (coronavirus) situation around the world. While some parts of our society are beginning to open in baby-steps, none of us know how the situation will develop over the coming months. As such, DBEI has now made the decision to postpone all our 2020 events to 2021 as the well-being of all our partners and participants in our events remains our utmost priority. For new details on each region please visit our event pages. We have also sent communications to all registered attendees, speakers or sponsors for all of our 2020 events.

In the interim, DBEI will be launching several exciting virtual events and webinars in 2020 to continue to deliver the same expertise, insights and knowledge to the AEC industry during these uncertain times. We also have some other exciting initiatives we are working on to continue to provide value to our community, which we look forward to sharing with you all shortly.

We wish to thank you all for your support and appreciate your patience and understanding under the current circumstances and will continue to update our website and the community if there are any changes.
