LIVERPOOL STREET – THAMESLINK PROGRAMME
Liverpool Street Station is one of the new underground stations proposed along the Crossrail network. The new station will be situated between the existing Moorgate and Liverpool Street LU stations. The construction of a new passageway to the new Crossrail Broadgate ticket hall will require the relocation of the existing switchroom and the existing Sprinkler Valve Chamber (SVC). In addition, the current passageway in front of the existing Station Control Facility (SCF) cannot accommodate the projected number of people at peak times and therefore the SCR has to be relocated.
The fire system enabling for Liverpool Street Crossrail project consisted of the relocation of the existing Station Operations Room and Sprinkler Valve Chamber and the creation of Switch room E12. Which consisted of the installation of a new fire sprinkler control valve set in the new SVC including the re routing of the incoming distribution main pipe work. Reconfiguration of the suppression and detection systems to accommodate the new layout.
