Super Nova Hospital, Kalyan

A hospital building on a 15 m wide road frontage, with a ground floor, a mezzanine, a first floor, a second floor and a third floor, served by passenger lifts and a stretcher lift, with a transformer area beside it. The first floor holds consulting rooms, relatives' waiting areas, a pathology lab, billing and administration, the director's cabin and an executive lounge. The second floor holds the operation theatre and X-ray rooms, and the third floor holds the patient rooms: eight special rooms, six suite rooms, five twin-sharing rooms, and a male and a female general ward, with a pantry. A hospital is wired and plumbed differently from any other building: every bedside needs medical-equipment power, every operating and imaging room needs its own supply and board, and drinking, flushing and RO water and clinical drainage must never mix.

Working from the hospital planner's and architect's layouts, our team engineered the building services. Electrical: layouts for the ground, mezzanine, second and third floors with numbered switch boards, general and 16 A power points, a pair of 16 A sockets for medical instruments at each bed, bedside power at 1,200 mm, 3-phase points on the second floor, X-ray display points, UPS control wiring and an operation-theatre board; on the third floor, 8-way three-phase boards fed through 40 A four-pole breakers with 100 mA residual-current protection for the wards, with geyser and TV points in the rooms. Lighting and fans: recessed and panel LED lights, a 1,000 W operation-theatre light, emergency lighting circuits, ceiling, wall, exhaust and in-line fans. Low voltage: LAN, Wi-Fi, telephone, CCTV and nurse-call bell points, with the 4-way and 1-way cassette and wall-mounted air-conditioner points shown on the same plans. Plumbing: layouts for the ground, mezzanine, second and third floors with 110 mm soil pipes, 75 and 40 mm waste pipes, separate flushing and drinking water and RO water lines, a drain to the effluent treatment plant, multi-traps, hot and cold angle cocks, and floor rises and under-sunk slabs of 150 to 600 mm coordinated with the structure. The drawings went through revisions from May to September 2025. Load and supply: the load statement, issued in seven revisions from September 2025 to August 2026 as the client's equipment list grew, lists every distribution board - 33 loads in all - 427.8 kW connected and 259.3 kW of maximum demand after diversity, which is 288 kVA at 0.9 power factor on a 500 kVA transformer, 58% loaded. The clinical equipment alone is 171 kW connected: a cath lab of 80 kW, two operating theatres of 16 kW each, X-ray 20 kW, 17 ventilators at 1.2 kW, a sterilisation plant, autoclave and laser. The emergency instrument and lighting boards, 46 kW connected, are kept on their own circuits for the standby supply.
