VAE works included the identification, audit, redesign, modification and testing of controls interfaces in excess of 40 complex switchboards, 480 HVAC devices and 400 access control devices. All works were required to be completed without disruption to passengers or flight schedules within a live airport that operates 24 hours per day, and handles over 1.4 million passenger movements a month. Adding to the complexity of this project, all airside works involved restricted access and ASIC clearance for all VAE employees and subcontractors.
A key deliverable of the project was safely supporting the transition of the facility's original fire control strategy (7 zones) into the new modernised fire control strategy (22 zones), with the resulting zone overlaps and translations carefully managed as part of a detailed and coordinated cutover strategy.
