A Square Properties Residential & Commercial Project, Talegaon Dabhade

A residential and commercial development by A Square Properties at Talegaon Dabhade, in the Maval taluka of Pune district, beside an 18 m road. Wing A rises from a basement, a ground floor and a first floor with mezzanine to the 14th floor, 43.6 m high, with 108 flats from two to four bedrooms; wing B, on the same basement, holds 70 flats from one to three bedrooms. Twenty-one shops line the ground and mezzanine floors of wing A, and the podium has a club house with a stage, a swimming pool and deck, a play area and lawns, with the sewage plant and transformer yard set into the site. The basement of 5,616 sq m holds the parking, the underground tanks and the pump rooms. A project of this size needs environmental clearance before it is built, so the MEPF design and the EC data were prepared together. The architecture is the architect's; our scope is the EC data and the MEPF design.

We prepared the calculations in June and the layouts for the environmental clearance in July 2026. Power: every flat at 75 W per sq m of carpet area and every shop at 150 W, seven lifts, the water, sewage, pool and sump pumps, the organic waste converter, basement ventilation and staircase pressurisation, the club house and street lighting, and charging for 30% of the parking - 43 car chargers of 7.2 kW and 53 two-wheeler chargers of 3.5 kW - for 1,908 kW connected and 796 kW of maximum demand on a 630 kVA and a 315 kVA transformer, with a 250 kVA DG set for the lifts, pumps, ventilation and common lighting, checked against the starting current of each motor. Energy: 72 kW of rooftop solar - 106 panels of 675 W across the two terraces - generating about 107 MWh a year; 13,350 litres a day of solar hot water from 107 collectors of 125 litres, 75 litres for each flat; timers on the common-area and street lighting; and drives on the lifts and 5-star pumps - together saving about 372 MWh a year. Water: 890 residents at 135 litres a day - 90 domestic and 45 flushing - and 386 people in the shops at 45 litres, with the lawn and pool, about 139 kL a day; underground tanks of 121 kL domestic water for the flats, 25 kL for the shops and 150 kL of fire water, 4 m deep, with overhead tanks on each wing; and a 130 KLD sewage plant whose treated water goes back to the flushing tanks and the lawn. Basement: 5,616 sq m in two fire zones, ventilated at 6 air changes an hour (about 65,450 CFM) and 12 in a fire, by fresh-air and exhaust axial fans and ceiling jet fans under carbon monoxide sensors; and drained by a 300 mm trench to two pumped sumps of 9 cu m. Site: four rainwater recharge pits with bores, de-siltation and oil-and-grease pits, storm water and sewer lines to the corporation mains, a 150 mm fire hydrant ring with hose boxes, EV charging, lightning arresters with chemical earthing on both terraces, and the solar layouts.
