Gaikwad Corp Residential & Commercial Project, Sr. No. 21 Punawale

Gaikwad Corp is developing a residential and commercial project at Sr. No. 21, Punawale, on the western edge of Pimpri-Chinchwad. It is one building: a basement, a ground floor and 18 residential floors with a terrace, holding 71 two-bedroom flats of about 71.5 sq m each and a refuge floor, with shops on the ground and mezzanine floors at the front. The construction area is 6,881.96 sq m on a plot of 2,000 sq m - more than three times the plot - so the water tanks, pump room and sewage treatment go into the basement, and the transformer, with the DG set above it, the meter room and the organic waste converter share the ground floor with the shops, the entrance and stack parking. The architecture is the architect's; our scope is the MEPF design, from the load and water calculations to the services in every flat.

We prepared the MEPF design between August and October 2026. Power: every flat at 75 W per sq m of carpet area, three 15 HP lifts, four shops at 150 W per sq m, the water, drinking-water, sewage and sump pumps, ventilation and staircase pressurisation fans, stack parking and EV charging for 20% of the 74 car bays - 591 kW connected and 291 kW of maximum demand, which is 323 kVA, or 388 kVA with a 20% margin, on one 630 kVA transformer, with 78 meter connections (71 single-phase flats, 4 three-phase shops and 3 common supplies) and a DG set for the lifts, pumps and common services. Water: 355 residents at 135 litres a person a day - 115 litres of domestic water and 20 litres of drinking water, which runs through its own treatment plant and pipes - 47.93 kL a day, plus the shops and the swimming pool make-up. Storage in the basement: 62 kL of domestic water (a day and a half), 21 kL of raw water, 15 kL of drinking water and a 200 kL fire tank, with 41 kL domestic, 8 kL drinking and 25 kL fire on the terrace; and 43.76 kL a day of sewage to a 50 KLD treatment tank. Fire: hydrant, sprinkler and jockey pumps, quick-response sprinklers in every flat and a fire alarm with smoke and heat detectors, manual call points, hooters and fire telephone jacks on every floor. Coordination: the schematic section showed the basement needs a 3.5 m floor height to keep the clear height under the beams for the pipes and cable trays. Flats: the typical-floor layouts place every light, fan, switchboard, socket, AC point and video door phone, the sprinkler and alarm devices, the soil, waste, rain-water, drinking-water and hot-water pipes, the sunk slabs and the AC drain downtakes, issued as R1 on 5 October 2026.
