Balvac has been awarded the contract. The contract will deliver substantial tunnel lining improvements, waterproofing and the installation of a drainage system to collect and control water.

"The subway modernisation programme is not just about better stations and new trains, it is also about ensuring the current infrastructure is maintained to a high standard and to protect the integrity of the system," said David Fagan, vice chair for SPT. "This major investment should be commended as in the longer term it will dramatically reduce maintenance costs."

The project is part of an overall USD 39M spend committed by SPT over the next five years to improve the network’s infrastructure and to minimise ongoing maintenance costs. Wider modernisation plans for the subway will deliver refurbished stations, new trains and signalling and smart card tickets.
