The project in brief

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 installation of a Fixed Fire Fighting System.

In 2018 it was decided that VID Fire-Kill´s TUNPROTEC® Low Pressure Watermist Solution was going to be installed during the refurbishment.

Why was a VID Fire-Kill solution chosen?

The TUNPROTEC® system offered several advantages to Land Transport Authority (LTA) e.g.:

  • TUNPROTEC offered significantly less consumption of water than conventional sprinkler systems
  • TUNPROTEC allowed for a significantly smaller water reservoir and drainage system
  • TUNPROTEC offered significantly less spatial requirements for pipes and valves
