Make OR Break Factor
We had no precedent to learn from as this was India’s first case of residential structure strengthening using fibre-wrapping.
THE CHALLENGE :
- A residential structure was extensively damaged in the 2001 Gujarat earthquake, and was unsuitable for continued inhabitation.
THE ODDS :
- 80 out of the 88 columns on the ground floor had failed
OUR RESPONSE :
- Pre-commencement, the existing structure was supported and jacked up to prevent it from collapsing during repairs
- Intense and detailed evaluations were carried out to evaluate extent of damage
- All cracked RCC members were grouted
- All RCC columns and beams were jacketed
- All RCC members were fibre wrapped
- Some of the concrete slabs were recast
- The facade was repaired and given its finishing touches
