Maithili Co-operative Housing Society (SK Fortune), Erandwane

Fortune Developers are building a new residential building for Maithili Co-operative Housing Society at Erandwane, in central Pune. It rises from a ground floor of entrance lobby, parking and services to twelve residential floors and a terrace, on a 1,027 sq m plot beside a 9 m road, with 10,000 sq m of construction. It holds 47 flats - 24 of two bedrooms, 22 of three and one five-bedroom home - served by two lifts and a fire tower, with mechanical car parking, a pump room and underground tanks at ground level. On a tight city plot, a tall building's tanks, pumps and parking all have to fit at the foot of the tower. The architecture is the architect's; our scope is the MEPF design.

We prepared the calculations and the layouts in June 2026. Power: every flat at 75 W per sq m of carpet area, two 15 HP lifts, the domestic and drinking-water pumps, the water treatment plant, sump and sub-soil pumps, staircase pressurisation, four mechanical car-parking units, street and common lighting, and charging for 20% of the 54 car bays - 11 chargers of 7.2 kW - for 484 kW connected and 235 kW of maximum demand: 261 kVA, or 313 kVA with a 20% margin, on one 315 kVA indoor transformer, with a three-phase supply to every flat - 49 connections in all; and a 160 kVA DG set for the lifts, pumps, parking and common lighting, checked against each motor's starting current. Water: 235 residents at 135 litres a day - 120 litres of domestic and 15 of drinking water on separate pipes - 31.7 kL a day, with domestic, drinking-water and fire tanks underground and on the terrace, and a 75 kL fire tank for the 45 HP hydrant and sprinkler pumps and the jockey pump. Layouts: the transformer, DG set, pump room, tanks and sumps placed on the ground-floor plan, with the tank plan and sections; and the internal services for the first, second, fifth, typical, refuge and terrace floors - plumbing cutouts, service slabs, 150 and 200 mm sunk areas and the fire duct opening into the fire lobby.
