• Provision of a new vertical hydrant riser and distributed ring mains across three pressure zones (Z1, Z2, Z3) with pressure-reduction stations as required.
• Installation of new fire hydrant outlets and hose reel outlets across all floors, including within stairways, carpark areas, and plantrooms.
