The archetypal factual basal slab of the Mumbai underground slug bid presumption was formed connected November 30, 2024, astatine a extent of astir 32 metres from the crushed level, which is equivalent to a 10-storey building. The presumption is being built utilizing the bottom-up method, which means that excavation enactment has commenced from the crushed level and the factual enactment has started from the foundation.
This slab is 3.5-meter-deep, measures astir 30 meters successful magnitude and 20 meters successful width. This is archetypal of the 69 slabs that volition beryllium formed for the presumption that volition signifier the deepest operation level for the slug bid station.
High-grade reinforced steel, 6200 rebar couplers, and 2254 cubic metres of M60 people factual on with 4283 MT( metric tonne) of aggregate factual are being utilized for casting of the slab.
Concrete pouring was temperature-controlled to beneath 25° Celsius, done in-situ crystal and chiller plants. Sufficient waterproofing measures person been ensured earlier casting the slab.

Platform 24 metres from crushed level
The level is planned astatine a extent of astir 24 metres from the crushed level. There volition beryllium 3 floors including a platform, concourse, and work floor.
Excavation is being done till a extent of 32 meters from the crushed level. The presumption volition person six platforms and the magnitude of each level is astir 415 m (sufficient to accommodate a 16-coach slug train).
The presumption volition person roadworthy and metro connectivity. Two entry/exit points are planned astatine the presumption — 1 to facilitate entree to the adjacent metro presumption and the different towards the MTNL building. The presumption has been planned successful a mode to spend rider question crossed the concourse and level level.
