Residential Project, Gat No. 273 P & 281 P, Borhadewadi

A residential project on a 2,124 sq m plot at Gat No. 273 P & 281 P, Borhadewadi, near Moshi on the northern edge of Pimpri-Chinchwad, with 12,081 sq m of construction. Two buildings, A and B, rise from a basement and a podium of parking to seven residential floors and a terrace, beside a 9 m road; building A holds 42 flats of one and two bedrooms and building B 39 two-bedroom flats - 81 in all - served by three lifts, with an open space and an amenity space at ground level. Homes of this size on a compact plot need their services kept efficient and their water reused. The architecture is the architect's; our scope is the EC data and the MEPF design.

We prepared the calculations and the first layouts in March and revised the external layout through June 2026. Power: every flat at 75 W per sq m of carpet area, three 5 HP lifts, the domestic, drinking-water and grey-water pumps, the basement sump, the organic waste converter, basement ventilation, street lighting and charging for 20% of the parking - 8 car chargers of 7.2 kW and 20 two-wheeler chargers of 3.5 kW - for 508 kW connected and 254 kW of maximum demand (282 kVA) on a 315 kVA transformer, on 84 connections: a single-phase supply to each of the 81 flats and 3 common; meter rooms with meter panels and sub-distribution panels for each building; and a 62.5 kVA DG set for the lifts, pumps, ventilation and common lighting, placed above the transformer room. Water: 405 residents at 135 litres a day - 70 domestic, 20 drinking and 45 flushing - and the landscape, about 56 kL a day, with underground tanks of 80 kL domestic, 20 kL drinking and 15 kL raw water, 3 m deep, and terrace tanks on each building, including 25 kL of fire water. Reuse: a 35 KLD grey-water treatment plant between the basement and the ground floor, returning 18 kL a day to the flushing system and watering the landscape, with the surplus to the municipal drain. Floors: the internal services location layout with the plumbing cutouts, service slabs, 150 and 200 mm sunk areas and the electrical and low-voltage slits for every floor and the terrace.
