The work is taking place as part of a significant upgrade of its largest data centre, Telehouse South at Docklands in London.
It will be the one of the largest fit-outs, in terms of financial value, that Skanska UK has undertaken.
Managing director Dan Williams from Skanska said: “We are excited to be working with Telehouse to deliver this project.
“It is something we are ideally suited for, as we are experienced in delivering a wide range of data centre fit-outs”
The project will see the mechanical, electrical and public health engineering fit-out of two of the top floors. This includes the installation of electrical plant and systems, together with air conditioning and ventilation.
A new roof gantry for plant will also be installed, together with new lifts.
The project also involves other construction work, including cladding replacement, reconfiguring the building’s secure entrances, a new gatehouse and new fencing.
The award follows Skanska’s delivery of an early works package at the data centre, as part of a preconstruction services agreement.
The project is being delivered by Skanska’s specialist mechanical, electrical and public health engineering arm, while the construction work will be delivered by Skanska’s buildings team.
Work on the main contract is due to be completed in June 2024.
