What Mall Construction Actually Looks Like in Bangalore
A mall is not just a big office building with shops in it. The structural grid is different. The loads are different. The services are different. We push column spacing out to 9 to 12 metres so anchor tenants get usable floor plates. Floor-to-floor heights sit at 4.8 to 5.5 metres because you need room for trunk ducting, sprinkler mains, signage bands, and a ceiling that still feels generous. Live loads are designed to IS 875 Part 2 for the 5 kN/sq.m that retail demands, and 7.5 kN/sq.m around the food court and anchor stores where fit-out weight adds up quickly.
We did a 2,40,000 sq.ft. community mall off Sarjapur Road two years ago. The water table sat at 2.8 metres. BBMP required two basement parking levels. So the first six months of that job were basically earth retention and dewatering, not concrete. That is the Bangalore reality on Outer Ring Road, Bannerghatta, and most of the Whitefield belt. You plan for shallow water, or you pay for it later. Our go-to approach: secant pile walls for the perimeter, well-point dewatering to drop the table by 1.5 to 2 metres during excavation, and M40 waterproof concrete with Kryton or Penetron crystalline admix (per IS 9103 for admixtures, IS 456 for the RCC itself). Honestly, most contractors skip the crystalline admix because it adds ₹180 to ₹220 per cubic metre. We do not. Ten years from now, the basement is still dry.
Escalator and lift shafts get their own headache. Each shaft punches through every slab, and the pit has to sit below the lowest basement. Equipment specs from Schindler, Otis, or Kone all differ slightly, so we coordinate shaft dimensions and pit loads against the supplier drawing before the raft is poured. Changing a shaft after the slab is cast costs roughly ₹4 to ₹6 lakh per floor. We would rather take the two weeks upfront.
What We Actually Build
- RCC framed structures, wide column grids, post-tensioned slabs where span demands it (IS 1343)
- Escalator wells and lift shafts. Reinforced edge beams, machine rooms, waterproofed pits
- Anchor store shells. Clear-span steel trusses, 6m+ ceilings, loading dock pits
- Food court infrastructure. Grease traps, stainless kitchen exhaust risers, cold water mains, gas routing
- Two and three-level basements with diaphragm or secant walls, dewatering, waterproof concrete
- Atriums and skylights. Long-span steel trusses, laminated glass per IS 2553, MS glazing frames
- Back-of-house. Service corridors, loading bays, bulk waste holding rooms with exhaust
- Facade substructure. MS framing for ACP cladding, curtain wall brackets, signage mounts
How We Run a Mall Job
Mall construction is a coordination problem first and a concrete problem second. We work closely with the MEP team and the interior design team so conduits, sleeves, and slab openings go in before the pour, not after. Chipping 200mm of finished slab to run a missed sleeve is the kind of thing you never want to do twice.
