Brookfield Multiplex sought Emerald’s assistance in overcoming a ventilation supply problem to the electrical substation beneath the building; soon to be the Wellesley Hotel. Emerald successfully tendered and implemented the rerouting of the ventilation system (including London Underground approved fire-rated ductwork) through the exterior portico of the hotel down into the substation, to provide an overall solution satisfactory to London Underground’s section 12 requirements

Part of the builder’s works element involved cutting out several tons of concrete using a water-based cutting rig from the substation ceiling whilst still operational at 11,000v directly underneath
