22-Floor Hospital, Hebbal
Project overview
A 22-floor hospital tower in Hebbal required a 14-hour continuous foundation pour and an aggressive 14-month structural schedule. Alpha delivered 4,800 m³ across M30 and M40 grades using night dispatch and a fast-track admixture system to enable 24-hour form stripping on slabs.
Active healthcare campus; noise restrictions during day; tight site access through ambulance corridors.
The challenge
Hospital noise limits and tight schedule.
- ›No daytime pumping during patient hours
- ›Foundation pour to complete in single shift overnight
- ›24h form-stripping for slab cycle to hold programme
- ›Coordinate with active hospital traffic
The solution
Night-shift dispatch with fast-track Alpha High-Rise.
- ›Pours scheduled 10pm-6am for foundation and slabs
- ›Fast-track admixture for 14h form-stripping
- ›Dedicated low-noise pump and silenced gensets
- ›Pre-clearance with hospital security per shift
Execution detail
14h foundation pour clean; 7-day slab cycle held.
- ›Foundation: 14h continuous, 343 m3/hr avg
- ›Slab cycle: 7 days held for 18 floors
- ›M40 28-day mean: 47.1 MPa
The result
Programme held; zero noise complaints from hospital admin.
