Proposed Bungalow, Pimpri-Chinchwad

A private family bungalow in Pimpri-Chinchwad, on the north-west side of Pune. The ground floor holds the parking, a waiting lobby and the electrical panel room; the first floor the living room, dining room, kitchen with store and utility, a pooja room and a terrace; the second floor a family area, a guest room and a master bedroom with a walk-in wardrobe; and the third floor a guest room and two more master bedroom suites, with the overhead water tank on the terrace above. A lift links all four levels. A house on four floors with a lift, a full modern kitchen and showers on every bedroom floor needs its power, water and drainage planned floor by floor before the slabs are cast. The architecture is the architect's; our scope is the MEPF design.

We prepared the calculations and the services layouts from February to August 2026, and issued the slab drawings as the structure went up. Power: every room's ceiling, cove and wall lights, fans and sockets listed floor by floor, with the kitchen appliances (10.4 kW), the plumbing pumps and a 10 kW heat pump (18 kW), an allowance of 7.39 kW for 10.65 TR of air conditioning (designed by others), a 5 HP lift, the AV system and the landscape lights - about 64 kW across the line items. A UPS with four hours of battery backup carries the lighting, the lift and the AV. Water: two methods side by side. By people, 10 residents at 450 litres a day - the norm for a five-star hotel - plus 500 litres for the landscape is 5 kL a day; by fixtures, four 60-litre-a-minute showers and the other fittings draw 285 litres a minute at peak, and 45 minutes of that is 12.8 kL - so the calculation calls for 15 kL of underground storage, with a 5,000-litre tank on the terrace. Drawings: the external and internal services layout for every floor - 110 mm soil, 75 mm waste and 75 mm rainwater pipes to storm water and sewage chambers with their invert levels, the incoming electricity supply through the meter and stabilizer to the distribution panel and the UPS battery rack, and the electrical chambers and hume pipe for the cable - revised in July to suit the site, with gully traps added and the underground tank set out; a first-slab layout of 110 mm and 75 mm sleeves, the electrical and plumbing cutouts and the 150 and 200 mm sunk areas, with the beams to be kept top-flush, or sunk, so the pipes can pass; and a ground-floor electrical layout with its switchboard schedule, conduits for power, lighting and CCTV, and a single-line diagram from a 40 A main breaker and a 30 mA earth-leakage breaker to a 12-way distribution board.
