• Remove and safely dispose of all existing air conditioning equipment.
• Provide all necessary components, including indoor/outdoor mounting brackets, refrigeration piping, insulation, drainage lines, cable containment, and electrical connections to a dedicated three-phase distribution board.
• Conduct pressure testing, system evacuation, functional commissioning, and formal handover.
• Execute ancillary builders' work, including core drilling, surface restoration, and paint touch-ups.
• Ensure all activities comply with occupational health and safety regulations while minimizing noise, dust, and operational disruption in an active healthcare environment.
