Girls Hostel, Karve Nagar

A girls hostel on a 272.10 sq m plot at Karve Nagar, Pune, with 822.01 sq m of construction on a pile foundation. The ground floor holds the reception and waiting area, the manager's office and administration, a study room, dining and café, the kitchen and store, a security and delivery point, a water station, the electrical panel room and DG set, and two-wheeler parking with charging points; above it, seven floors of four rooms each - 28 rooms of about 22.4 sq m with three beds and an attached toilet - 84 beds in all, served by one lift. On a plot this small, every service has to share the ground floor with the people who use it. The architecture is the architect's; our scope is the MEPF design.

We prepared the calculations in August and the drawings from September to October 2026. Power: every room at 75 W per sq m, the lift, the water and drinking-water pumps, a 20 HP heat pump for hot water, the terrace booster pump, street lighting and EV charging - two car chargers of 7.2 kW and two two-wheeler chargers of 3.5 kW - for 108 kW connected and 52 kW of maximum demand: 58 kVA, or 70 kVA with a 20% margin, on a 315 kVA transformer. Backup: an 82.5 kVA DG set sized on the lift (starting), the pumps, the heat pump, the common lighting and the rooms at 60% diversity, and in every room a 1 kVA inverter with a 332 Ah, 12 V battery for four hours of lights, fans and sockets. Water: 84 residents at 135 litres a day - 11.34 kL - from an 18 kL underground tank (2 m deep), with 12 kL domestic and 20 kL fire water on the terrace, and 10.21 kL a day of sewage to a 20 KLD plant. Rooms: the typical-floor electrical layout places each light, fan, AC point, geyser and socket, with the room's single-line diagram - a 40 A main breaker and a 30 mA earth-leakage breaker feeding a 12-way distribution board, with a 20 A geyser circuit - and the plumbing layouts cover every floor, the underground tank, the 300 mm storm water gutter at 1 in 300, the ground-floor pipe diversions at ceiling level and the connections to the existing sewage and storm water chambers.
