Shree Associates Commercial Building, Vadgaon

A commercial building by Shree Associates & Developers at Vadgaon, in south Pune, with 5,481 sq m of construction on a 1,900 sq m plot. Two large showrooms take the ground and mezzanine floors; the six floors above each hold two offices; and the lower ground holds the pump room, the underground tanks, the meter room and the transformer, with stack parking for the cars. Two lifts serve the building. An office building where every unit is sold or let separately needs its own meter, its own risers and its own backup planned in from the start. The architecture is the architect's; our scope is the MEPF design.

We prepared the calculations and layouts from June to September 2026, revising them as the building changed. Power: every showroom and office at 150 W per sq m of carpet area, two 10 HP lifts, the domestic, raw-water and terrace booster pumps, four stack-parking units, street and common lighting, and charging for 20% of the parking - 5 car chargers of 7.2 kW and 12 two-wheeler chargers of 3.5 kW - for 595 kW connected and 298 kW of maximum demand: 331 kVA, or 397 kVA with a 20% margin, on one 630 kVA indoor transformer, with 15 connections, 14 of them CT meters; and a 320 kVA DG set sized to carry the lifts, pumps and common services together with the showrooms and offices, checked against each motor's starting current. Distribution: 450 x 75 mm and 300 x 50 mm cable trays from the meter room, with the commercial meter panel, changeover panel and building common panel, and every ground-floor light, fan, socket, telephone point and indoor AC unit placed on the fixture layout. Fire: 150 mm hydrant and sprinkler headers, single hydrant valves, hose reels and hose boxes on every floor, and an underground fire tank, with two options for the tank layout drawn in August. Plumbing: 110 mm soil, 75 mm waste, 40 mm basin waste and 150 mm rainwater pipes with multi-floor traps for every floor, and where pipes could not run under the office floors, the toilets were sunk to the outside of the building or raised 200 mm on the first and second floors.
