Commercial Building with Restaurant, Vadgaon

A commercial building at Vadgaon, in south Pune, on a plot of 1,500 sq m with 4,582 sq m of construction: three basements, a lower ground and an upper ground floor, seven upper floors and a terrace. The upper ground and first floors are a showroom of about 460 sq m, the second to the sixth floors have more than fifty offices of 40 to 76 sq m, and the seventh floor is a restaurant of 381 sq m with its kitchen. Five lifts serve the floors and puzzle parking fills the basements. The restaurant and the offices have different needs and different hours, so the services had to be split: two diesel sets, separate water tanks, and a ventilation system for basements 10.6 m below the street. The basements are deep, so the design had to get groundwater out as well as supply water in.

Electrical: the load sheet follows the distribution company's guidelines of 14 November 2025 at 150 W per sq m: 653 kW for the showrooms, offices, restaurant, lifts and common lighting, 37 kW for plumbing, 50 kW of ventilation and pressurization, 53 kW for puzzle parking and street lighting, and 220 kW for charging - 1,013 kW in all, 499 kW after diversity, 555 kVA and 666 kVA with a 20% margin; the sheet lists a 630 kVA oil-filled indoor transformer. Two diesel sets were sized: 250 kVA for the common services and the restaurant (234.9 kVA at 80%, 187.9 kVA) and 500 kVA for the showrooms and offices (474 kVA at 80%, 379 kVA). Charging is provided for 20% of the parking - 11 car chargers of 7.2 kW and 41 two-wheeler chargers of 3.5 kW. Water: the demand is 51.9 kLD - the restaurant alone takes 17 kLD and its kitchen 10 kLD - with underground tanks of 21 kL domestic (offices), 36 kL domestic (restaurant), 15 kL flushing and 200 kL fire, overhead tanks of 14, 24, 15 and 20 kL, a 50 kLD sewage plant (46.7 kLD of sewage) that returns 41.5 kLD, and a filling pump of 14.8 m3/h at 40 m. Basement: sumps with duplex submersible pumps (one working, one standby) and 65 mm UPVC SCH-80 pumping lines to the ground floor, 150 mm plum-concrete trenches under perforated gratings, sleeves through the walls, and a sub-soil drain of 110 mm geotextile-wrapped perforated pipes and 200 mm drain belts under the raft with heavy-duty FRP manhole covers. Layouts: the services layout went from R0 on 30 October 2025 to R9 on 23 September 2026; the dewatering and sub-soil layouts from March to October 2026; and the basement ventilation layout was drawn on 15 July 2026.
