Diagnomediq Diagnostic Centre, Aundh

A diagnostic imaging centre at Aundh in Pune, over a ground floor, four upper floors and a terrace. The ground floor holds the MRI scanner with its control and equipment rooms beside the reception; the first floor the CT scanner, the X-ray room, a bone density room and a patient room; the fourth floor sonography, a report room, three OPDs and a feeding room; and the terrace the cabins, a conference room and a VIP lounge. The second and third floors are let separately on their own meters. The architecture is the architect's; our scope is the MEP design.

We prepared the water demand, the first load sheet and the plumbing layouts in May 2026, the heat loads and VRF selection in mid-May, and the revised load sheet and main power schematic at the end of the month. Power: lighting at 1 W and raw power at 3 W per sq ft, UPS power, the MRI at 100 kW, the CT scanner at 40 kW and X-ray at 35 kW, a 20 kW fire pump, the compressor, pumps, lift and air conditioning, and the two let floors come to 342 kW connected and 177 kW of demand, 196 kVA, for which a 315 kVA transformer is recommended. A 250 kVA DG set on an AMF panel takes over through a 500 A four-pole automatic transfer switch with over- and under-voltage protection; a 60 kVAR, eight-stage power factor panel and class B surge protection sit on the main board, the CT and X-ray machines have their own power distribution units, and a 15 kVA online UPS holds the lighting and UPS sockets for 30 minutes. Cooling: VRF on every floor - outdoor units of 11, 13, 10 and 10 tons for the ground, first, fourth and terrace floors, 26 indoor units in all, with ducted units of 4.5 tons for the MRI and CT rooms and 4 tons for X-ray, and cassettes and wall units elsewhere, each room with its fresh air. Water: about 4,100 litres a day for 91 people, from a 7 kL underground tank to 5 kL of domestic and 10 kL of fire water on the terrace. Drainage: 110 mm soil, 75 mm waste, 50 mm urinal and 40 mm basin pipes to 150 mm RCC sewers and 450 x 900 mm chambers, with 200 mm RCC storm water pipes.
