Example project
1,200 apartments, every toilet connected the same way
Residential towers- Scope
- Drainage + water supply
- Team
- 3 modelers
- Size
- 2 towers, 38 floors
Typical floors repeated across two towers. The team connected one toilet group per apartment type, copied the branches to every floor and only adjusted the exceptions.
