Project overview
Tour Montparnasse — Paris' tallest and most controversial building — is undergoing a comprehensive renovation to transform it from a 1970s eyesore into a modern, sustainable landmark. BIM is driving the renovation, coordinating new facade, structural reinforcement, and MEP system replacements.
What made this project complex
Renovating a 59-storey occupied tower while maintaining partial operations required surgical precision. Existing documentation was inconsistent, and the original 1970s construction contained numerous undocumented modifications.
How BIM coordination delivered
Point cloud scanning established accurate existing conditions. A phased renovation model in Revit allowed construction sequencing floor-by-floor while maintaining building operations. MEP replacements were coordinated through Navisworks to minimise disruption.
Measurable outcomes
Created accurate as-built model from 1970s-era tower
Enabled phased construction while maintaining occupancy
Coordinated full MEP system replacement across 59 floors
Reduced renovation timeline by 6 months through virtual coordination
