McMullen was awarded the package by main contractor Laing O’Rourke who are working for developer Delancey in partnership with Oakmayne Properties.
McMullen will start working on the 23-storey West Tower this August.
Work will involve providing the complete vertical envelope using a unitised system with bolt-on balconies, brise soleil and feature aluminium cladding.
The ‘fast track’ installation is due to take just 23 weeks with McMullen completing one floor per week on average.
