Road tunnels, Singapore

The Kallang-Paya Lebar & Central Expressway twin-tube tunnels (cut & cover) opened in 2008. In 2018 Land Transport Authorities (LTA) initiated a tender for refurbishing the tunnels including the installation of a Fixed Firefighting System. In 2018 it was decided that VID FIREKILL’s TUNPROTEC® solution should be installed during the refurbishment.

KPE Tunnel protected with watermist

Why was a VID FIREKILL solution chosen?

• The TUNPROTEC® solution offered a significantly lower water consumption than conventional sprinkler systems.
• The TUNPROTEC® solution allowed for a much smaller water reservoir and drainage system.
• The TUNPROTEC® solution offered significantly fewer spatial requirements for pipes and valves.
