Proposed Residential Project, Manik Baug

A residential building at Manik Baug, off Sinhgad Road in south-west Pune: a ground floor with the entrance lobby and G+1 puzzle parking, and six floors above with four two-bedroom flats each - 24 flats of about 64 and 67 sq m carpet area, served by one lift. The plot is tight, with 3 m margins and a 6 m road in front that is to be widened to 9 m, so the tanks, septic tank, meters and pipe routes have to fit around the parking, and the soil and waste pipes have to leave the building without cutting through beams. The architecture is the architect's; our scope is the MEPF design, from the load and water calculations to a fully detailed sample flat.

We prepared the calculations in August and the drawings in October 2026. Power: every flat at 75 W per sq m of carpet area, the lift, the water, drinking-water and terrace booster pumps, street lighting, and EV charging for 20% of the parking - five car chargers of 7.2 kW and four two-wheeler chargers of 3.5 kW - for 188 kW connected and 89 kW of maximum demand: 99 kVA, or 119 kVA with a 20% margin, on a 315 kVA transformer with 25 meter connections, and a 30 kVA DG set for the lift, pumps and common lighting at 80% diversity. Water: 120 residents at 135 litres a person a day - 115 litres of domestic and 20 litres of drinking water on separate pipes - 16.2 kL a day, with underground tanks of 21 kL domestic, 7 kL raw and 4 kL drinking water, terrace tanks of 14 kL domestic, 3 kL drinking and 25 kL for fire, and a 15 KLD septic tank. Plumbing: the ground-floor diversion and external layout - corporation inlet, storm water and sewage chambers, the overflow to the existing sewer, and the fire hydrant and hose reel - and the typical-floor layouts with concealed-cistern and wall-hung WCs, sunk slabs, ledge walls and dry-balcony and kitchen-sink details, with a note to keep beam tops flush where the soil and waste pipes run out of the building. Sample flat: every light, fan, switchboard and socket, the AC, geyser, inverter, water-purifier and video door phone points, and the flat's single-line diagram - a 40 A main breaker and a 30 mA earth-leakage breaker feeding a 16-way distribution board with C-curve breakers sized circuit by circuit.
