Nuvoco Completes Hiranandani Hospital Project Despite All Odds

100 CE&CR June 2018

had to be poured beneath the existing RCC slab in the basement with

uniform density throughout the bunker as per the AERB (Atomic

Energy Regulatory Board) standards. It must be mentioned that the

guidelines are stringent and AERB as a Regulatory Body does not permit

commissioning of a facility till the most stringent specifications are met.

Nuvoco took up the challenge and ensured that pouring of the

concrete was done in a manner that did not hinder hospital operation

even for a day. For the final slab, the pouring of concrete was done

through core cuts from the ground floor. To achieve the required density

and uniform spreading of the self-compacting concrete the mixing must

be 100 per cent accurate, which was accomplished by Nuvoco. The job

was done so meticulously that the centre passed the AERB Radiation Leak

Test with flying colours. It was not a small achievement as the area above

the bunker has 100 per cent occupancy by people.

To complete the project successfully, Nuvoco

used Agile concrete with a compressive strength of

40 MPa. Around 700 cu.m. concrete was used for the

entire project. Agile is a self-compacting, self-levelling

concrete that provides solutions and opportunities

for design and placement. A fluid concrete that flows

freely around congested steel reinforcement and fully

compact without any added placing energy. Agile is

ideal for both vertical and horizontal constructions and

delivers excellent filling in congested reinforcement and

smooth surface finish with no vibration. The main benefits are:

- Self-compacting, self-levelling and free flowing

- No Vibration

- Easier to place

- Worksite Flexibility

- Excellent surface finish

this project was different since it was for a hospital. The project was

for Oncology Radiation Chamber Room, Hiranadani Hospital, Mumbai.

Nuvoco had to retrofit a bunker in the basement pouring concrete

in RCC Wall covered by 1-m thick top RCC slab. It was a challenging

project because we had to pour concrete in the basement bunker of the

operating hospital without disturbing their daily routine. The concrete

Pouring the concrete as per AERB standards, which is very stringent.

Project had to be completed without hampering a single day’s work of the hospital.

Concrete had to be poured beneath the existing RCC slab with uniform density.

The floor over bunker had 100% occupancy by people.
