Proposed Residential Project, S. No. 28, Ambegaon

A residential project on a 3,577 sq m plot at S. No. 28, Ambegaon, in south Pune, with 12,288 sq m of construction. Two buildings, A and B, each rise from a basement and a ground floor to ten residential floors and a terrace, with eight flats on each typical floor - one-room-kitchen (1RK), two-bedroom homes of about 62 to 67 sq m and three-bedroom homes of about 87 to 94 sq m carpet area - 158 flats in all, reached from a five-foot corridor round the lift and fire-tower core. Mechanical stack parking, the sewage plant, the underground tanks and the transformer room sit at the foot of the buildings. A compact plot of this size has to fit its tanks, plant and parking without losing a flat, and its slabs carry every service from the start. The architecture is the architect's; our scope is the MEPF design.

We prepared the calculations and the services location layouts in May, and the slab and typical-floor drawings from September to October 2026. Power: every flat at 75 W per sq m of carpet area, the lifts, the domestic, drinking-water and sewage pumps, the water treatment plant, organic waste converter and basement sumps, basement ventilation, street and amenity lighting, 59 stack-parking units and charging for 20% of the 117 car bays - 23 chargers of 7.2 kW - for 1,233 kW connected and 617 kW of maximum demand: 685 kVA, or 822 kVA with a 20% margin, on a 630 kVA and a 315 kVA transformer, with 162 connections - 98 single-phase for the 1RK and two-bedroom flats, 60 three-phase for the three-bedroom flats and 4 common; and a 250 kVA DG set for the common services, placed above the transformer room. Water: 135 litres a person a day - 70 domestic, 20 drinking and 45 flushing - about 108 kL a day, with underground tanks of 56 kL domestic, 28 kL raw, 24 kL drinking and 150 kL fire water, 4 m deep, and a 100 KLD sewage plant, with the organic waste converter above it, returning 36 kL a day to the flushing system. Floors: a floor height of 3.4 m, keeping 300 mm below the beams for services. Basement of wing A: the first-slab sleeve and cutout layout with every electrical, fire and plumbing cutout and 200 mm fire sleeves through the beams; the sprinkler layout with 68 °C quick-response heads and 150 mm hydrant and sprinkler headers; the fire alarm with heat detectors, manual call points, hooters and fire telephone jacks; the ventilation cutouts; and the lighting, power and CCTV conduits. Typical floor: every flat's lights, fans, sockets, AC, geyser and inverter points, a video door phone, the sunk and ledge walls for the toilets, and single-line diagrams for the two- and three-bedroom flats.
